It is very important that your doctor check your or your child's progress at regular visits to allow for changes in your dose and to make sure this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.
Clomipramine may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some children, teenagers, and young adults to have suicidal thoughts and tendencies or to become more depressed. Some people may have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. Also tell the doctor if you or your child have sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. If you, or your caregiver notice any of these side effects, tell your doctor right away. Let the doctor know if you, your child, or anyone in your family has bipolar disorder (manic-depressive) or has tried to commit suicide.
Do not use clomipramine with a monoamine oxidase (MAO) inhibitor (eg, isocarboxazid [Marplan®], linezolid (Zyvox®), phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start using clomipramine during the 2 weeks after you stop an MAO inhibitor. Wait for 2 weeks after stopping clomipramine before you start using an MAO inhibitor. If you take them together or do not wait 2 weeks, you may develop confusion, agitation, restlessness, stomach or bowel symptoms, a sudden high body temperature, an extremely high blood pressure, or severe convulsions (seizures).
Clomipramine may cause a serious condition called serotonin syndrome if taken together with some medicines. Do not use clomipramine with buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), lithium (Eskalith®, Lithobid®), tryptophan, St. John's wort, or some pain or migraine medicines (eg, sumatriptan, tramadol, Frova®, Maxalt®, Relpax®, Zomig®).

Be careful when using sharp objects, including razors and fingernail clippers.
