Useful information should make the next appointment clearer

Psychiatric medicines are not one category. Antidepressants, antipsychotics, mood stabilisers, ADHD medicines, sedatives and sleep medicines, and medicines used in addiction and dementia have different benefits, risks, monitoring needs and stopping considerations. A claim that is true of one group can be unsafe when copied to another.

Choice depends on the working diagnosis, which symptoms are causing impairment, previous response, physical health, other medicines, substance use, pregnancy or breastfeeding, cost and availability, and your own priorities. Medication may be one part of care, and it is not automatically the first or the only part.

Everything below is written at the level of the medicine group. It names generic molecules so that you can recognise what you have been prescribed, and it deliberately gives no doses, no schedules and no way to pick a medicine for yourself.

Do not use this page to change treatment yourself. A severe reaction, overdose, high fever with muscle stiffness or confusion, a spreading rash, fainting, marked agitation, new or worsening thoughts of suicide, or an inability to stay safe all need urgent clinical assessment, not a webpage.

The medicine groups

What each group is for, and what it asks of you

Find the group you have been prescribed. Each entry covers what it treats, what benefit tends to look like, the effects people most often notice, the effects that need prompt review, what is monitored and what matters when stopping.

Antidepressants

Generic names you may seeSSRIs: fluoxetine, sertraline, escitalopram, paroxetine, fluvoxamine. SNRIs: venlafaxine, desvenlafaxine, duloxetine. Others: mirtazapine, bupropion, vortioxetine, agomelatine, trazodone. Tricyclics: amitriptyline, nortriptyline, imipramine, clomipramine.
Used for
EstablishedDepression, generalised anxiety, panic disorder, social anxiety, OCD, PTSD and premenstrual dysphoric disorder, depending on the specific molecule. Also used forDuloxetine and amitriptyline are used in some pain and neuropathic conditions, and low-dose amitriptyline is used in migraine prevention. Bupropion is also used in smoking cessation.
What benefit looks like
Sleep, appetite, energy and concentration often shift before mood does. A first change is often visible within about two weeks, with fuller effect over four to eight weeks. OCD and some anxiety disorders can take longer. The target should be agreed at the start so that benefit is judged against something specific.
Common effects
Nausea, headache, changed sleep, dry mouth, and sexual effects including reduced desire or delayed orgasm. Anxiety or restlessness can briefly increase in the first days. Mirtazapine tends to increase sedation and appetite. Bupropion tends not to cause sexual effects but can disturb sleep.
Needs prompt review
New or worsening suicidal thoughts, particularly in the first weeks and particularly under the age of 25. A switch into elevated or agitated mood, which can reveal an underlying bipolar illness. Confusion or unusual drowsiness in an older adult, which may indicate low sodium. Agitation with fever, sweating, tremor and muscle twitching, which needs emergency assessment.
Monitoring
Clinical review of benefit and adverse effects, more closely at the start. Sodium in older adults where indicated. Blood pressure with venlafaxine and duloxetine. Liver tests with agomelatine. Caution when combined with anti-inflammatory painkillers or blood thinners because of bleeding risk. Tricyclics are dangerous in overdose, which affects how they are prescribed.
Stopping
Not addictive, but stopping suddenly can cause withdrawal symptoms such as dizziness, electric-shock sensations, nausea, irritability and vivid dreams. Paroxetine and venlafaxine are more likely to do this. Reduction is planned individually, and withdrawal is not the same as relapse. How to tell withdrawal from relapse.

Antipsychotics

Generic names you may seeSecond generation: risperidone, olanzapine, quetiapine, aripiprazole, amisulpride, paliperidone, lurasidone, cariprazine, ziprasidone, blonanserin. First generation: haloperidol, trifluoperazine, chlorpromazine, fluphenazine. Also clozapine, and long-acting injections of several of these.
Used for
EstablishedSchizophrenia and related psychoses, and mania in bipolar disorder. Some are established in bipolar depression. Also used forAdding a second-generation antipsychotic to an antidepressant is a recognised option in depression that has not responded, and low doses are used in severe agitation. Clozapine is used when at least two other antipsychotics have failed.
What benefit looks like
Agitation and sleep can improve within days. Hallucinations, delusions and disorganised thinking usually improve over weeks. Negative symptoms and cognition respond least. The aim is function, not sedation, so a person who is merely flattened is not being treated well.
Common effects
Sedation, weight gain and metabolic change, which are most marked with olanzapine and clozapine. Restlessness that is hard to sit still with, called akathisia, which is often mistaken for worsening anxiety. Stiffness, tremor and slowed movement. Raised prolactin with risperidone, paliperidone and amisulpride, which can affect periods, breast tissue and sexual function.
Needs prompt review
High fever with muscle rigidity, confusion and instability needs emergency assessment. Persistent involuntary movements of the face or tongue need review, because tardive dyskinesia can become lasting. On clozapine, fever, sore throat or flu-like illness needs a same-day blood count, and chest pain or breathlessness in the first weeks needs urgent assessment. Severe constipation on clozapine is a serious problem, not a minor one.
Monitoring
Weight and waist, blood pressure, blood glucose or HbA1c and lipids, because metabolic effects are common and treatable. Prolactin when symptoms suggest it. An ECG for some medicines and in some physical conditions. Clozapine requires a defined blood-count schedule and is prescribed within a monitoring system for that reason.
Stopping
Not addictive. Stopping abruptly raises the risk of relapse and can cause nausea, sleeplessness and rebound symptoms. In a first episode that has fully recovered, a planned reduction may be reasonable. In recurrent illness the balance is usually different. This is a decision to make together, with a relapse plan agreed in advance.

Mood stabilisers

Generic names you may seeLithium carbonate, sodium valproate and divalproex, carbamazepine and oxcarbazepine, lamotrigine. Several antipsychotics are also used as mood stabilisers.
Used for
EstablishedPreventing relapse in bipolar disorder, treating mania, and lamotrigine for preventing the depressive pole. Lithium is an established long-term relapse-prevention treatment, and evidence has associated lithium treatment with a lower risk of suicide in mood disorders. Also used forLithium is used to augment antidepressants in resistant depression.
What benefit looks like
Mania settles over days to weeks. Prevention of relapse is judged over months and years, which is why people often stop these medicines at exactly the point they are working. Lamotrigine is introduced slowly, so its effect is assessed over a longer period.
Common effects
Lithium: thirst, passing more urine, fine tremor, weight gain, and effects on thyroid over time. Valproate: sedation, weight gain, hair thinning, tremor. Carbamazepine: dizziness, unsteadiness, and many drug interactions, including reduced effectiveness of hormonal contraception. Lamotrigine: headache and sleep change, and rash during introduction.
Needs prompt review
On lithium, vomiting, diarrhoea, coarse tremor, slurred speech, unsteadiness or confusion may indicate toxicity and needs same-day assessment. Dehydration, a new anti-inflammatory painkiller, a diuretic or a blood-pressure medicine can all push a stable level into the toxic range. On lamotrigine or carbamazepine, any spreading rash, especially with fever or mouth ulcers, needs urgent assessment because rare severe skin reactions occur.
Monitoring
Lithium needs blood levels together with kidney and thyroid function, and calcium. Valproate and carbamazepine need liver tests and blood counts. Carbamazepine interacts with a long list of other medicines, so every new prescription should be checked against it. How lithium entered psychiatry.
Pregnancy
This group needs a planned conversation before conception wherever possible. Valproate carries a high risk of birth defects and of developmental problems in the child, and it should not usually be used by anyone who could become pregnant unless there is no suitable alternative and effective pregnancy prevention is in place. Lithium and carbamazepine also carry specific risks that need individual discussion. Do not stop any of them abruptly on your own.

ADHD medicines

Generic names you may seeStimulant: methylphenidate. Non-stimulant: atomoxetine. Alpha-2 agonists: clonidine and guanfacine, used mainly in children and adolescents. Modafinil is not a guideline-standard ADHD treatment.
Used for
EstablishedADHD in children, adolescents and adults, after a proper diagnostic assessment. Medication is one part of care alongside practical support, treatment of coexisting anxiety, depression or sleep problems, and adjustments at school or work.
What benefit looks like
Stimulant effect is felt within hours, so benefit can be judged within days rather than months. Atomoxetine works gradually over several weeks. Benefit means sustained attention, less impulsive decision-making and better task completion, not sedation or a personality change.
Common effects
Reduced appetite, difficulty falling asleep, headache, dry mouth, and a rebound of irritability as the effect wears off. Atomoxetine can cause nausea, sedation or sexual effects. Alpha-2 agonists cause sedation and lower blood pressure.
Needs prompt review
Chest pain, fainting or palpitations. A marked rise in blood pressure or pulse. New agitation, low mood or suicidal thinking, particularly in young people starting atomoxetine. In children, appetite loss that begins to affect growth.
Monitoring
Benefit, sleep, appetite, mood, pulse and blood pressure, plus height and weight in children. Misuse and diversion risk is assessed honestly rather than assumed. What is actually monitored on ADHD medication.
India rules
Methylphenidate is a Schedule X medicine and is listed under the NDPS Act. It cannot be prescribed in a teleconsultation under India's Telemedicine Practice Guidelines, and the prescription and record-keeping requirements are stricter than for ordinary prescription medicines. Assessment, review and non-stimulant treatment can be handled online. Methylphenidate compared with atomoxetine · Non-stimulant options in India.

Anxiety and sleep medicines

Generic names you may seeBenzodiazepines: clonazepam, lorazepam, alprazolam, diazepam, etizolam. Z-drugs: zolpidem, zaleplon, eszopiclone. Others: melatonin, buspirone, hydroxyzine, propranolol, pregabalin.
Used for
EstablishedShort-term relief of severe anxiety or insomnia, panic while a longer-term treatment takes effect, alcohol withdrawal under supervision, and some seizure and movement conditions. NoteFor long-term anxiety and for chronic insomnia, the treatments with the better evidence are psychological. Cognitive behavioural therapy for insomnia outperforms sleeping tablets over time.
What benefit looks like
Fast and obvious, which is exactly why these medicines are easy to keep taking. Benefit should be defined as getting through a defined period, not as a permanent solution.
Common effects
Drowsiness, slowed reactions, poor concentration and impaired memory for the period of the effect. Driving is affected. In older adults, falls and confusion are a serious risk. Z-drugs can cause complex behaviours during sleep that the person does not remember.
Dependence
Tolerance and physical dependence develop with regular use, and more quickly with shorter-acting molecules. Stopping abruptly after sustained use can cause severe withdrawal, including seizures, so it is not something to do alone. This is the group where the difference between dependence and addiction matters most. Dependence, tolerance and addiction explained.
Dangerous combinations
Alcohol and opioids together with this group suppress breathing. This combination is a common cause of preventable death and is not a matter of tolerance or willpower. Pregabalin also carries misuse potential and adds to sedation.
Stopping
Reduction is gradual and individual. There is no schedule that suits everyone, because it depends on the medicine, how long it has been taken, other sedatives, physical health and previous withdrawal experience. Stopping sleeping tablets safely · CBT for insomnia, week by week.

Medicines used in alcohol, tobacco and opioid problems

Generic names you may seeAlcohol: naltrexone, acamprosate, disulfiram, and baclofen off-label. Tobacco: nicotine replacement, varenicline, bupropion. Opioids: buprenorphine with naloxone, and methadone, which require appropriately authorised clinical services. Withdrawal: benzodiazepines and thiamine, supervised.
Used for
EstablishedReducing craving and relapse in alcohol dependence, supporting tobacco cessation, and opioid substitution treatment. These medicines work best alongside psychological and social support, not instead of it.
What benefit looks like
Fewer heavy drinking days, longer gaps between episodes, less craving, and more capacity to use psychological treatment. Complete abstinence is one possible goal, not the only measure of progress.
Important cautions
Disulfiram causes a deliberate and severe reaction if alcohol is taken, so it is used only when the person understands this fully and there is no significant heart disease. Naltrexone blocks opioid painkillers, which matters in an emergency, and needs liver assessment. Thiamine is given in alcohol withdrawal to prevent a serious and preventable brain injury.
Withdrawal
Alcohol withdrawal can be dangerous and can cause seizures and delirium. Stopping heavy sustained drinking without medical support is not safe. Opioid substitution treatment has additional legal, service and monitoring requirements and should be arranged through an appropriately authorised service.

Medicines used in dementia

Generic names you may seeDonepezil, rivastigmine, galantamine, memantine.
Used for
EstablishedAlzheimer's disease, and rivastigmine in dementia associated with Parkinson's disease. Memantine is used in moderate to severe disease or when the other group is unsuitable.
What benefit looks like
Modest. These medicines may slow decline and help attention, apathy and day-to-day function for a period. They do not reverse dementia, and expectations should be set honestly with the family at the start.
Common effects and monitoring
Nausea, reduced appetite, diarrhoea, vivid dreams, and a slowed pulse. Fainting or a very slow pulse needs review. Antipsychotics are used with particular caution in dementia because of raised risks of stroke and death, and should be reserved for severe distress or risk, at the lowest effective dose, and reviewed frequently.

Off-label uses and adjuncts

What off-label meansThe medicine is licensed, but it is being used for a purpose or in a group for which it is not formally approved. This is legal and sometimes appropriate, and it should always be stated openly, with the reason and the strength of the evidence.
Reasonable and commonly used
Propranolol for the physical symptoms of performance anxiety, with caution in asthma. Melatonin for delayed sleep timing and shift or travel disruption. Low-dose amitriptyline for migraine prevention. Trazodone or mirtazapine for sleep when depression is also being treated. Prazosin for nightmares in PTSD, where the evidence is mixed rather than settled.
Limited or early evidence
N-acetylcysteine, omega-3 supplements and a number of nutraceuticals marketed for mood and memory have limited or inconsistent evidence and should not displace treatment that works. Botulinum toxin has one established psychiatric-adjacent use in this practice, chronic migraine, and its role in depression remains research. Where the botulinum toxin evidence actually is.
Worth questioning
Fixed-dose combination products are common in India and some pair medicines that would be better prescribed and adjusted separately. If you have been given a combination tablet, it is fair to ask what each component is for and whether it could be prescribed as separate medicines.

India

Prescription rules that affect your treatment

Many psychiatric medicines in India are listed in Schedule H and may be sold only on a registered medical practitioner's prescription. Schedule H1 adds a separate pharmacy register that is kept for three years. For Schedule X medicines, the prescription is in duplicate and the pharmacy retains one copy for two years. Methylphenidate is listed in Schedule X and as a psychotropic substance under the NDPS Act. India's Telemedicine Practice Guidelines prohibit remote prescribing of Schedule X medicines and listed narcotic or psychotropic substances.

The same active ingredient may be sold under different brands and in different release formulations. Asking for the generic name makes the prescription easier to understand, but modified-release products are not automatically interchangeable. Check any brand or formulation switch with your prescriber or pharmacist. Price and availability can change.

Start with your question

Reading, arranged by what people actually ask

01 · Before starting or choosing

The first question is not which medicine is strongest

It is whether the working diagnosis is sound, what outcome is being targeted, what non-medication options fit, and how benefit and harm will be reviewed.

02 · Benefit, review and monitoring

Monitoring is how treatment stays accountable

Define the target, look for meaningful change, ask about adverse effects, and check the physical measures or tests that are relevant to that medicine.

03 · Side effects, without panic or dismissal

Some settle, some can be managed, a few need urgent help

Side effects should be discussed before and after starting. A new symptom should be neither automatically blamed on the medicine nor automatically ignored.

04 · Dependence, withdrawal and stopping

Physical dependence is not the same as addiction

Antidepressants can cause withdrawal without causing craving or compulsive use. Benzodiazepines and Z-drugs can cause tolerance and dependence, especially with longer use. Abrupt stopping can be harmful in both cases.

05 · Pregnancy, breastfeeding and everyday safety

The safest plan is the individual one

Decisions weigh the known and uncertain risks of a medicine against the risks of an untreated or relapsing illness. Do not stop an effective psychiatric medicine suddenly because of a positive pregnancy test or an alarming post online. Alcohol, driving, over-the-counter painkillers and supplements all belong in the same conversation.

Take to your appointment

Seven questions worth asking

  1. What specific problem is this medicine intended to help, and what is its generic name?
  2. What benefit would be meaningful, and when will we review it?
  3. Which common effects should I expect, and which symptoms need urgent help?
  4. What physical checks or tests are relevant for me, and why?
  5. Could this interact with alcohol, driving, over-the-counter medicines or supplements?
  6. Does pregnancy, breastfeeding, another illness or another medicine change the plan?
  7. If it does not help, or if I later want to stop, how will that decision be made safely?

Common questions

Answered plainly

How long does a psychiatric medicine take to work?

It depends on the medicine and the problem. Antidepressants often show a first change within about two weeks and a fuller effect over four to eight weeks, and anxiety disorders and OCD can take longer. Antipsychotics can reduce agitation within days while other symptoms improve over weeks. Stimulant medication for ADHD acts within hours, so benefit is judged quickly. Lithium and lamotrigine are judged over a longer period. Your prescriber should tell you at the start what change is being looked for and when it will be reviewed.

Are psychiatric medicines addictive?

It depends entirely on the group. Benzodiazepines and Z-drug sleeping medicines can cause tolerance and dependence, especially with longer use. Stimulants used for ADHD carry a misuse risk that has to be assessed. Antidepressants are not addictive in the sense of causing craving and compulsive use, but stopping them suddenly can cause withdrawal symptoms, which is a different thing. Antipsychotics, lithium and lamotrigine are not addictive. Physical dependence and addiction are not the same, and the difference matters when you are deciding what to do.

Why does my psychiatrist want blood tests?

Monitoring makes treatment accountable rather than dangerous. Lithium needs blood levels along with kidney, thyroid and calcium checks. Clozapine needs regular blood counts. Most antipsychotics need weight, blood pressure, glucose or HbA1c and lipid checks because of metabolic effects. Some medicines need liver tests. What is checked and how often depends on the medicine, your physical health and how long you have been taking it, so there is no single timetable that fits everyone.

Can psychiatric medication be prescribed in an online consultation in India?

Many can, and some cannot. Methylphenidate is a Schedule X medicine and is listed under the NDPS Act, so it cannot be prescribed in a teleconsultation under India's Telemedicine Practice Guidelines. Assessment, review and non-stimulant treatment can be handled online. Other prescription medicines are governed by the same guidelines and by the prescriber's clinical judgement about whether an online assessment is adequate for that person and that situation.

Can I drink alcohol while taking psychiatric medication?

Alcohol adds sedation to most psychiatric medicines and can make thinking, balance and driving worse. The combination of alcohol with benzodiazepines, Z-drugs or opioids is dangerous because breathing can be suppressed. Alcohol also worsens sleep quality and mood over time, which works against the treatment. Disulfiram causes a severe reaction with alcohol by design. Ask your prescriber about your specific medicine rather than assuming a general rule.

Is it safe to take psychiatric medication during pregnancy?

The decision weighs the known and uncertain risks of the medicine against the risks of an untreated or relapsing illness, which are real and are often underestimated. Some medicines are avoided where possible. Valproate in particular should not usually be used by anyone who could become pregnant unless there is no suitable alternative and effective pregnancy prevention is in place, because of a high risk of birth defects and developmental problems. Do not stop an effective medicine suddenly because of a positive pregnancy test. Ask for a planned discussion, ideally before conception.

Will I have to take this medicine for life?

Often not, and sometimes yes. It depends on the diagnosis, how many episodes there have been, how severe they were, what happened on previous attempts to stop, and what you want. A single episode of depression is usually treated for a defined period after recovery rather than indefinitely. Recurrent bipolar disorder or schizophrenia frequently needs longer-term treatment. The honest answer is that this is reviewed over time, not decided once.

Why was this medicine chosen for me and not a different one?

Choice depends on the working diagnosis, which symptoms are causing the most impairment, what has worked or not worked before, physical health and other medicines, substance use, pregnancy plans, cost and availability, and your own priorities about which side effects you are least willing to accept. There is no strongest or best psychiatric medicine. It is reasonable to ask why this one, what the alternatives were and what would trigger a change.
