Clomipramine (Anafranil) is a tricyclic antidepressant used to treat obsessive-compulsive disorder (OCD). It can be used by children as young as 10 years old. The medication is taken by mouth and your dosage might increase over several weeks. Clomipramine (Anafranil) isn't a first-choice medication because of the high risk for side effects such as dry mouth, sleepiness, weight gain, and headaches.
Obsessive-compulsive disorder (OCD)
Clomipramine (Anafranil) is a tricyclic antidepressant (TCA). It's believed to help raise the amounts of specific chemicals in the brain, like serotonin. This balancing act helps control behavior, feelings, mood, and thoughts linked to obsessive-compulsive disorder.

When you first start taking clomipramine (Anafranil) and your provider is slowly raising your dose, your provider might ask you to take this medication in split doses with meals to lower the risk of stomach upset.
Once you're on a stable dose of clomipramine (Anafranil), your provider might recommend you to take it at bedtime because this medication can make you feel sleepy.
Don't stop taking clomipramine (Anafranil) all of a sudden or change the amount that you're taking without talking to your provider first. This can cause withdrawal symptoms like nausea, headache, and overall discomfort. If appropriate, your provider can help you stop your medication safely and slowly over time.
Antidepressant medications like clomipramine (Anafranil) can raise the risk of suicidal thoughts. Contact your provider right away if you notice any new, worsening, or unusual changes in your behavior or mood while taking this medication.
Clomipramine (Anafranil) can cause drowsiness and dizziness, making you less alert. Avoid driving and doing anything that requires concentration or focus until you see how this medication affects you.
Clomipramine (Anafranil) can cause you to gain weight. Check your weight regularly after you start this medication. If you're concerned about how much weight you're gaining, talk with your provider.
Let your provider know if you're planning to have surgery where you'll need general anesthesia. You might need to temporarily stop clomipramine (Anafranil) and your provider can help you do so safely.
Clomipramine (Anafranil) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: People age 24 years or younger | History of depression or other mood problems | Taking antidepressants | Starting clomipramine (Anafranil) for the first time | Change in dose of clomipramine (Anafranil)
Clomipramine (Anafranil) can raise the risk of suicidal thoughts or behavior. Watch for new or worsening depression, suicidal thoughts or behavior, especially during the first few months of treatment or when the dose changes. Let your healthcare provider know right away if you notice any unusual changes in mood or behavior while taking this medication.
Risk factors: History of bipolar disorder | At risk for bipolar disorder
Sometimes, depression is the first symptom of bipolar disorder. Treating someone with bipolar disorder with an antidepressant alone can cause a manic episode. Symptoms of a manic episode include great excitement, euphoria, delusions, and overactivity. This is more likely to happen if you or someone in your family has had bipolar disorder. Your healthcare provider should make sure you're evaluated for bipolar disorder before starting clomipramine (Anafranil). Talk to your provider right away if you notice unusual changes in your behavior.
Risk factors: Taking clomipramine (Anafranil) with other medications that raise serotonin levels
Serotonin syndrome is a rare, but potentially life-threatening, condition that happens when there's too much serotonin active in the brain. This is more likely to happen if you're also taking other medications that affect serotonin levels, such as other antidepressants, monoamine oxidase inhibitors (MAOIs), lithium (Lithobid), and triptans. Symptoms of serotonin syndrome include fast heartbeat, sweating, muscle stiffness or spasms, fever, and confusion. Go to the emergency room right away if you think you are having these symptoms.
Risk factors: History of seizure | Taking other medications that raise seizure risk | Brain damage | Drinking alcohol | Taking higher doses of clomipramine (Anafranil) | Taking clomipramine (Anafranil) for a long time
Clomipramine (Anafranil) can raise the chance of seizures for some people, including those who have had seizures in the past. Clomipramine (Anafranil) is generally not recommended if you have a history of seizures. Talk to your healthcare provider to see if this medication is safe for you.
Risk factors: Older adults | Taking medications to control blood pressure | Raising clomipramine (Anafranil) dose too quickly
While taking clomipramine (Anafranil), you might experience dizziness and falls due to a sudden drop in blood pressure when changing positions (such as going from sitting to standing). If you're sensitive to low blood pressure or are on medications to control your blood pressure, change positions slowly until your body is used to clomipramine (Anafranil). If you still feel dizzy after a week or two, talk to your provider since a different medication may be better for you.
Clomipramine (Anafranil) can cause your pupils to widen, which, for some people with an underlying eye condition, can lead to an eye problem called angle-closure glaucoma. Symptoms of this can include eye pain, headache, changes in vision, nausea, and vomiting. Your healthcare provider might want you to have an eye exam to see if you have a higher chance of these eye problems before taking clomipramine (Anafranil).
Risk factors: Older adults | Taking water pills
Clomipramine (Anafranil) can lower your sodium level. Your risk for this problem is higher if you're also taking water pills, such as furosemide (Lasix). A low sodium level can be dangerous because it might lead to seizures or death. Let your provider know if you experience symptoms such as headache, difficulty concentrating or remembering, weakness, or feeling unsteady on your feet.
Although rare, serious skin reactions called Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome have been reported with clomipramine (Anafranil). Watch out for symptoms including fever, rash, and internal organ involvement and notify your provider immediately.
Dosing for clomipramine (Anafranil) is typically started at a low dose and slowly raised by your provider depending on how you respond to the medication.
