Clomipramine - oral


Patient Medicine Information
Why do I need this medicine?
Clomipramine is used to treat depression.

It can also be used to treat phobias (irrational or disabling fears), and obsessive-compulsive disorder or OCD (a disorder characterised by uncontrollable urge to do repetitive and ritualised behaviours).

Clomipramine may also be used together with other medicines to treat cataplexy (a sudden and uncontrollable muscle weakness usually triggered by strong emotions such as laughter) in people with narcolepsy (a sleep disorder that causes a person to suddenly fall asleep).

This medicine may be used to treat other conditions as decided by your doctor.
How do I take this medicine?
Take Clomipramine exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.

Medicines for depression such as Clomipramine may increase the risk of suicidal thoughts and behaviour. As depression and some psychiatric disorders are themselves associated with an increased risk of suicide, it is important for you or your family members to monitor your condition especially at the start of treatment and if your dosage is still being adjusted. If you experience new or sudden changes in mood, behaviour, thoughts or feelings or a worsening of your depression with suicidal thoughts or attempts, harm to self or harm to others, contact your doctor immediately.

Certain enzymes called CYP2D6 and CYP2C19 are involved in the metabolism of this medicine. Individuals who are poor metabolisers of CYP2D6 and CYP2C19 may experience enhanced side effects of Clomipramine (e.g. dry mouth, constipation) that may require dose adjustments. Although not routinely done, your doctor may advise you to undergo genetic testing to check if this medicine is best suited for you. If you know you have this gene type, inform your doctor.

Keep your appointments with your doctor. Your doctor needs to monitor your condition and check your response to the medication regularly.
  • Your blood pressure and pulse may rise to unsafe levels without you noticing it. You may need to monitor your blood pressure and pulse before and periodically during your treatment.
  • You may need to have routine tests (e.g. kidney and liver function, blood sodium levels, ECG) while you are being treated with Clomipramine. Your doctor will advise you about how often you will need to have these tests.
  • Monitoring of signs of suicidal thoughts or attempts, and unusual changes in behaviour may also be needed.
What lifestyle changes should I make to cope with depression?

Regular exercise and eating a healthy diet will help increase energy and hormones in the body such as serotonin, endorphins and other feel-good chemicals that minimise mood swings. Get enough sleep, as lack of sleep may cause irritability, moodiness, sadness, and tiredness.
What side effects could I experience?
Clomipramine may cause dizziness, drowsiness, or some problems with your eyesight such as blurred vision. If affected, do not drive or take part in any activity in which you need to be alert.

This medicine may cause your blood pressure to fall suddenly when you get up from a sitting or lying down position and you may feel giddy. To minimise this problem, stand up slowly.

Other side effects include any of the following: headache, dry mouth, constipation, nausea, vomiting, diarrhoea, increased appetite, weight gain or loss, excessive sweating, hot flushes, ringing in the ears, yawning, tremors, restlessness, tiredness, and difficulty sleeping.

Some side effects may need immediate medical help. Alert your doctor quickly if you experience any of the following:
  • having thoughts of self-harm
  • unusual changes in mood or behaviour (being too depressed, irritable, confused, too excited, aggressive, or having compulsive and impulsive behaviour)
  • hallucinations (seeing, hearing or feeling things that are not existent)
