4. How and when to take amitriptyline for depression
You'll usually take amitriptyline once a day. It's best to take it before bedtime because it can make you feel sleepy. If you find that you are still feeling drowsy in the morning you could try taking it earlier in the evening.
Dosage and strength
Amitriptyline tablets come in different strengths of 10mg, 25mg or 50mg.
Amitriptyline liquid also comes in 3 different strengths containing 10mg, 25mg or 50mg of amitriptyline in a 5ml spoonful.
The usual dose of amitriptyline for depression in adults is 50mg to 100mg a day. This may go up to 150mg a day if you need a stronger dose, but only under the supervision of a specialist.
Young people aged 16 to 17 years and older people sometimes start on a lower dose of 25mg to 50mg a day to reduce the chance of side effects.
The maximum dose of amitriptyline is 150mg per day.
Sometimes, when you're just starting treatment, you may be told to take a lower dose, 2 or 3 times a day, until you get used to the medicine. This is because taking a smaller dose 2 or 3 times a day for a while can reduce the chance of you having side effects.
How to take it
Amitriptyline does not usually upset your stomach, so you can take it with or without food.
Swallow the tablets whole with a drink of water. If you chew them, they taste bitter.
The liquid comes with a plastic syringe or spoon to help you measure out the right dose. If you do not have one, ask your pharmacist for one. Do not use a kitchen teaspoon as it will not measure the right amount.
What if I forget to take it?
If you take amitriptyline once a day and forget a dose, leave your missed dose and take your next one the next day at the usual time.
If you take amitriptyline 2 or 3 times a day and forget a dose, take it as soon as you remember unless it's close to the time for your next dose.
Never take 2 doses at the same time to make up for a forgotten dose.
If you often forget doses, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
What if I take too much?
The amount of amitriptyline that can lead to an overdose varies from person to person.
Taking more than your prescribed dose of amitriptyline can:
- make you feel agitated
- make you sick (vomiting)
- cause shaking
- cause a fast heart rate

6. How to cope with side effects of amitriptyline
What to do about:
- constipation – eat more high-fibre foods such as fresh fruit and vegetables and cereals.
Try to drink several glasses of water or other non-alcoholic drinks every day. If you can, it may also help to increase your level of exercise. - feeling dizzy – this is probably due to low blood pressure. Drink plenty of water or other non-alcoholic drinks. Do not stand up too quickly after you have been sitting or lying down. Do not drive until you stop feeling dizzy.
- dry mouth – try sugar-free gum or sugar-free sweets.
- feeling sleepy or tired – take amitriptyline in the evening and try to cut down the amount of alcohol you drink. Do not drive, cycle or use tools or machinery if you're feeling sleepy. Talk to your doctor if this does not help.
- difficulty peeing – try to relax when you pee. Do not try to force the flow of urine. If you still cannot go, try again later. Talk to your doctor urgently if you cannot pee at all.
- headaches – make sure you rest and drink plenty of fluids.
Try not to drink too much alcohol. Paracetamol and ibuprofen may help if you need pain relief. Talk to your doctor if the headaches last longer than a week or are severe.
7. Pregnancy and breastfeeding
Amitriptyline and pregnancy
If you are already taking amitriptyline, you may be advised to continue taking it during pregnancy, especially if you take it to treat depression.
If you become pregnant while taking amitriptyline, speak to your doctor. Do not stop taking your medicine unless your doctor tells you to.
Your doctor can explain how taking amitriptyline can help you and how it might affect you. They will also help you choose the best treatment for you and your baby.
Amitriptyline and breastfeeding
If your doctor or health visitor says your baby is healthy, you can take amitriptyline while breastfeeding.
Amitriptyline passes into breast milk in very small amounts, so it's unlikely to cause any harm to your baby.
It's important to keep taking amitriptyline to keep you well. Breastfeeding will also benefit both you and your baby.
If you notice that your baby is not feeding as well as usual, or seems unusually sleepy, or if you have any other concerns about your baby, then talk to your midwife, health visitor or doctor as soon as possible.
Non-urgent advice: Tell your doctor if you're:
- trying to get pregnant

- codeine
- morphine

9. Common questions about amitriptyline
How does amitriptyline work in depression?Amitriptyline is from a group of medicines called tricyclic antidepressants. They are thought to work by increasing levels of a chemical called serotonin in your brain. This can improve your mood.
When will I feel better?You may find you are feeling better after a couple of weeks, although it usually takes between 4 and 6 weeks before you feel the full benefit of the medicine.
Do not stop taking amitriptyline after 1 or 2 weeks just because you feel it is not helping your symptoms.
Give the medicine at least 6 weeks to work.
Antidepressants like amitriptyline help to gradually lift your mood so you feel better. You may notice that you sleep better and get on with people more easily because you're less anxious. Hopefully you'll take little things that used to worry you in your stride.
Amitriptyline will not change your personality or make you feel euphorically happy. It will simply help you feel like yourself again.
Do not expect to feel better overnight though. Some people feel worse during the first few weeks of treatment before they begin to feel better.
How long will I take it for?Once you're feeling better it's likely that you will keep taking amitriptyline for several more months. Most doctors recommend that you take antidepressants for 6 months to a year after you've stopped feeling depressed.
Stopping before then can make depression come back.
Talk to your doctor about the risks and benefits of taking amitriptyline for longer than a few months. It will depend on:
- how bad your symptoms are
- whether it's a one-off problem or it keeps coming back
- how well amitriptyline works for you
- any bad side effects you've had
Amitriptyline is safe to take for a long time. There do not seem to be any lasting harmful effects from taking it for many months or years.
Is it addictive?Amitriptyline is not addictive but you can get withdrawal side effects if you stop taking it suddenly.
Do not stop taking it without talking to your doctor first.
What will happen when I stop taking it?If you've been feeling better for 6 months or more, your doctor may suggest coming off amitriptyline.
Your doctor may recommend reducing your dose gradually over several weeks, or longer if you have been taking amitriptyline for a long time.
This is to help prevent any withdrawal side effects you might get as a reaction to coming off the medicine. These include:
- feeling dizzy
- feeling sick
- numbness or tingling in the hands or feet
- trouble sleeping
- feeling agitated or anxious
- headaches
- shaking
Important
Do not stop taking amitriptyline suddenly, or without talking to your doctor first.
Will I gain or lose weight?Amitriptyline can change how hungry you feel. Some people feel more hungry when they're taking it, while others feel less hungry.
So your weight may change when you first start taking it.
If you start to have problems with your weight while taking amitriptyline, talk to your doctor or a pharmacist.
Can I drive or ride a bike?Some people feel sleepy while they're taking amitriptyline. It's best to stop driving and cycling for the first few days of treatment until you know how this medicine makes you feel.
It's an offence to drive a car if your ability to drive safely is affected. It's your responsibility to decide if it's safe to drive. If you're in any doubt, do not drive.
Talk to your doctor or pharmacist if you're unsure whether it's safe for you to drive while taking amitryptyline. GOV.UK has more information on the law on drugs and driving.
Is amitriptyline better than other antidepressants?Amitriptyline does not work any better or worse than other antidepressants.
However, for some people, the side effects are a problem and they may have fewer side effects with another antidepressant. Sometimes people respond better to one antidepressant than to another.
Talk to your doctor if you are not feeling any better after taking amitriptyline for 6 weeks, or sooner if the side effects are still a problem.
Are there other treatments that will help?Antidepressants, including amitriptyline, are just one of several approaches to treating depression. Other potential treatments include:
- talking therapy (such as cognitive behavioural therapy (CBT))
- exercise programmes
- help to get a good night's sleep
Choosing a treatment that's most suitable for you depends on:
- how long you've had depression
- your symptoms
- whether you've had depression before
- whether previous treatment has worked
- how likely you are to stick with your treatment
- the potential side effects
- your preferences and priorities
You can drink alcohol while taking amitriptyline but it may make you feel sleepy.
It might be best to stop drinking alcohol until you see how the medicine makes you feel.
You can eat and drink normally while taking amitriptyline. However, it might be best to stop drinking alcohol until you see how the medicine makes you feel.
Will it affect my contraception?Amitriptyline does not affect any type of contraception, including the combined pill and emergency contraception.
Will it affect my sex life?The good effects of amitriptyline may, after a while, improve your sex life as your mood lifts and you become interested in life and relationships again.
Some of the possible negative effects include:
- having problems with getting an erection and problems ejaculating
- having some vaginal bleeding
Sexual side effects are not common and should pass after the first couple of weeks.
If they do not, and this is a problem for you, go back to your doctor to see if there's another antidepressant you can try.
If you get vaginal bleeding after the menopause make an appointment to see your doctor as soon as possible.
Will it affect my fertility?There's no evidence that amitriptyline affects either male or female fertility.
Will recreational drugs affect it?Cannabis with amitriptyline can give you a fast heartbeat. Cannabis can also make drowsiness worse, especially if you've just started taking amitriptyline.
Methadone and other opiates (for example, heroin) can increase the risk of severe drowsiness if you're taking amitriptyline.
It can be dangerous to take amitriptyline with:
- stimulants like MDMA (ecstasy) or cocaine
- hallucinogens like LSD
- novel psychoactive substances (previously called legal highs), like mephedrone
Find out more the side effects of some recreational drugs on the Frank website.

Update date: 2021.12.06 Marketing authorization holder:DALHIMFARM JSC (Russia) ATX code: N06AA09(Amitriptyline) Active substance: amitriptyline (amitriptyline) Rec.INN WHO registered Dosage form
Release form, packaging and composition drug Amitriptyline Tablets white with grayish to white with a yellowish tinge, flat-cylindrical shape with a bevel. Excipients : lactose monohydrate (milk sugar) - 51.1 mg, potato starch - 14.47 mg, microcrystalline cellulose - 4 mg, colloidal silicon dioxide (aerosil) - 0.08 mg, gelatin - 1.05 mg, calcium stearate - 1 mg. 10 pcs. - cellular contour packings (5) - packs of cardboard. Clinical and pharmacological group: Antidepressant Pharmacotherapeutic group: Antidepressant Pharmacological actionAntidepressant from the group of tricyclic compounds, dibenzocycloheptadine derivative. The mechanism of antidepressant action is associated with an increase in the concentration of norepinephrine in the synapses and/or serotonin in the CNS due to inhibition of neuronal reuptake of these mediators. With prolonged use, it reduces the functional activity of β-adrenergic receptors and serotonin receptors in the brain, normalizes adrenergic and serotonergic transmission, restores the balance of these systems, disturbed during depressive states. It also has some analgesic effect, which is thought to be related to changes in CNS concentrations of monoamines, especially serotonin, and effects on endogenous opioid systems. It has a pronounced peripheral and central anticholinergic effect due to its high affinity for m-cholinergic receptors; a strong sedative effect associated with affinity for histamine H 1 receptors, and alpha-adrenergic blocking action. The mechanism of therapeutic action in bulimia nervosa has not been established (possibly similar to that in depression). Amitriptyline has been shown to be clearly effective in bulimic patients both without depression and in its presence, while a decrease in bulimia can be observed without a concomitant weakening of the depression itself. Efficacy in bedwetting appears to be due to anticholinergic activity resulting in increased bladder distensibility, direct β-adrenergic stimulation, α-adrenergic agonist activity associated with increased sphincter tone and central blockade of serotonin uptake. It has an antiulcer effect, the mechanism of which is due to the ability to block histamine H 2 receptors in the parietal cells of the stomach, as well as to have a sedative and m-anticholinergic effect (in case of gastric ulcer and duodenal ulcer, it reduces pain, accelerates the healing of the ulcer). Reduces blood pressure and body temperature during general anesthesia. Does not inhibit MAO. Antidepressant effect develops within 2-3 weeks after the start of use. PharmacokineticsThe bioavailability of amitriptyline is 30-60%. Plasma protein binding 82-96%. V d - 5-10 l/kg. Metabolized to form the active metabolite nortriptyline. T 1/2 - 31-46 hours Excreted mainly by the kidneys. Indications of the active substances of the drug Amitriptyline Depression (especially with anxiety, agitation and sleep disorders, including in childhood, endogenous, involutional, reactive, neurotic, drug-induced, with organic brain damage, alcohol withdrawal), schizophrenic psychoses, mixed emotional disorders, behavioral disorders (activity and attention), bulimia nervosa, tension headache, migraine, neuropathic pain, chronic pain in cancer patients, rheumatic pain, nocturnal enuresis (except for patients with bladder hypotension), peptic ulcer of the stomach and duodenum.

Effects due to anticholinergic activity: dry mouth, tachycardia, disturbances of accommodation, blurred vision, mydriasis, increased intraocular pressure (only in persons with a narrow anterior chamber angle of the eye), constipation, paralytic ileus, urinary retention, decreased sweating, confusion, delirium, or hallucinations. Other: hair loss, tinnitus, edema, hyperpyrexia, swollen lymph nodes, pollakiuria, hypoproteinemia. Contraindications for use Acute period and early recovery period after myocardial infarction, acute alcohol intoxication, acute intoxication with hypnotics, analgesics and psychotropic drugs, angle-closure glaucoma, severe disorders of AV and intraventricular conduction II degree), lactation period, children under 6 years of age (for oral administration), children under 12 years of age (for intramuscular and intravenous administration), simultaneous treatment with MAO inhibitors and the period 2 weeks before their use, increased sensitivity to amitriptyline. Use in pregnancy and lactationAmitriptyline should not be used during pregnancy, especially in the first and third trimesters, except in cases of emergency. Adequate and strictly controlled clinical studies of the safety of the use of amitriptyline during pregnancy have not been conducted. Amitriptyline should be phased out at least 7 weeks before expected delivery to avoid neonatal withdrawal. In experimental studies amitriptyline was teratogenic. Contraindicated during lactation. It is excreted in breast milk and may cause drowsiness in infants. Use in hepatic impairmentUse with caution in hepatic impairment. Use in impaired renal functionUse with caution in impaired renal function. Pediatric useContraindication: children under 6 years of age (for oral administration), children under 12 years of age (for intramuscular and intravenous administration). Use in elderly patients In elderly patients, it can provoke the development of drug-induced psychoses, mainly at night (after discontinuation of the drug pass within a few days), and also cause paralytic ileus. Special instructionsUse with caution in ischemic heart disease, arrhythmia, heart block, heart failure, myocardial infarction, arterial hypertension, stroke, chronic alcoholism, thyrotoxicosis, during therapy with thyroid drugs, with impaired liver and / or kidney function. During therapy with amitriptyline, care must be taken when abruptly moving to an upright position from a lying or sitting position. Abrupt discontinuation may lead to withdrawal syndrome. Amitriptyline at doses greater than 150 mg/day lowers the seizure threshold; the risk of developing epileptic seizures in predisposed patients should be taken into account, as well as in the presence of other factors that increase the risk of developing a convulsive syndrome (including with brain damage of any etiology, simultaneous use of antipsychotic drugs, during the period of refusal of ethanol or withdrawal of drugs, with anticonvulsant activity). Consideration should be given to the possibility of suicide attempts in patients with depression. Should only be used in combination with electroconvulsive therapy under close medical supervision. In predisposed patients and elderly patients, it can provoke the development of drug-induced psychoses, mainly at night (after discontinuation of the drug they disappear within a few days). May cause paralytic ileus, predominantly in patients with chronic constipation, the elderly, or in patients requiring bed rest. Before general or local anesthesia, the anesthesiologist should be warned that the patient is taking amitriptyline. With prolonged use, an increase in the incidence of caries is observed. May increase the need for riboflavin. Amitriptyline can be used no earlier than 14 days after discontinuation of MAO inhibitors. Do not use simultaneously with adreno- and sympathomimetics, incl. with epinephrine, ephedrine, isoprenaline, norepinephrine, phenylephrine, phenylpropanolamine. Use with caution concomitantly with other anticholinergic drugs. Do not drink alcohol while taking amitriptyline. Influence on the ability to drive vehicles and mechanisms During the period of treatment, one should refrain from potentially hazardous activities that require increased attention and rapid psychomotor reactions. Drug interactionsWhen used simultaneously with drugs that have a depressant effect on the central nervous system, a significant increase in the inhibitory effect on the central nervous system, hypotensive effect, and respiratory depression is possible. When used simultaneously with drugs with anticholinergic activity, it is possible to increase anticholinergic effects. With simultaneous use, it is possible to increase the effect of sympathomimetic agents on the cardiovascular system and increase the risk of developing cardiac arrhythmias, tachycardia, and severe arterial hypertension. When used simultaneously with antipsychotics (neuroleptics), metabolism is mutually inhibited, while the threshold for convulsive readiness decreases. When used simultaneously with antihypertensive agents (with the exception of clonidine, guanethidine and their derivatives), it is possible to increase the antihypertensive effect and the risk of developing orthostatic hypotension. With simultaneous use with MAO inhibitors, the development of a hypertensive crisis is possible; with clonidine, guanethidine - it is possible to reduce the hypotensive effect of clonidine or guanethidine; with barbiturates, carbamazepine - it is possible to reduce the effect of amitriptyline due to an increase in its metabolism. A case of the development of serotonin syndrome with simultaneous use with sertraline is described. With simultaneous use with sucralfate, the absorption of amitriptyline is reduced; with fluvoxamine - increases the concentration of amitriptyline in the blood plasma and the risk of developing a toxic effect; with fluoxetine - the concentration of amitriptyline in the blood plasma increases and toxic reactions develop due to inhibition of the CYP2D6 isoenzyme under the influence of fluoxetine; with quinidine - it is possible to slow down the metabolism of amitriptyline; with cimetidine - it is possible to slow down the metabolism of amitriptyline, increase its concentration in blood plasma and develop toxic effects.
