Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Contact lens wearers: People who wear contact lenses should be cautious as clomipramine may decrease tear production in the eye, thereby increasing the chance of eye damage for those wearing contact lenses.
Dental effects: Lengthy treatment with clomipramine may lead to an increased incidence of dental cavities. You should have regular dental checkups and practice good dental hygiene while taking this medication.
Drowsiness/reduced alertness: Since clomipramine may cause drowsiness, especially at the beginning of treatment, caution should be used when engaging in activities requiring mental alertness, judgment, and physical coordination such as driving or operating machinery.
Medical conditions: Anyone with a history of seizures or conditions that lower the seizure threshold (such as alcoholism or withdrawal from alcohol) should be closely monitored by their doctor while taking clomipramine.
Anyone with the following conditions should be monitored by their doctor while taking clomipramine:
- a history of heart disease
- thyroid disorders
- problems with urination
- a history of liver disease
Orthostatic hypotension (dizziness upon arising): Move slowly when rising from a sitting or lying down position as clomipramine can cause sudden temporary low blood pressure resulting in dizziness.
Suicidal or agitated behaviour: People taking antidepressants such as clomipramine may feel agitated (restless, anxious, aggressive, emotional, trouble sleeping, and feeling not like themselves), or they may want to hurt themselves or others. If you notice any changes in mood, behaviours, thoughts, or feelings in yourself or someone who is taking this medication, contact a doctor immediately. Your doctor will monitor you closely for behaviour changes, especially at start of treatment or when your dose is increased or decreased.
Withdrawal: Withdrawal symptoms such as dizziness, nausea, headache, and sleep disturbance have occurred when clomipramine therapy is discontinued suddenly. This is not a sign of addiction. Check with your doctor before stopping this medication on your own.
Pregnancy: The safety of this medication for use by pregnant women has not been established. It should not be taken by pregnant women unless the benefits outweight the risks.
Breast-feeding: Since clomipramine passes into breast milk, breast-feeding women should gradually withdraw the medication or stop breast-feeding.
Children: Clomipramine has not been studied for use by people under 10 years of age, and specific recommendations for its use by this age group cannot be provided. The long-term effects of clomipramine on childhood growth and development have not been determined.
