Anafranil (Generic Clomipramine): Complete Medication Guide
Key Takeaways
Anafranil (clomipramine) is a tricyclic antidepressant used to treat obsessive-compulsive disorder, depression, and certain anxiety conditions.
Generic clomipramine is the same medication as brand-name Anafranil but costs significantly less.
Common side effects include dry mouth, drowsiness, and constipation, which often improve over time.
This medication requires regular monitoring and should never be stopped abruptly without medical guidance.
Doctronic's AI doctors can help you understand whether clomipramine is right for your situation and monitor your treatment progress.
Anafranil (Generic Clomipramine) Overview
Anafranil is the brand name for clomipramine, a medication that belongs to a class of drugs called tricyclic antidepressants (TCAs). It works by increasing levels of certain brain chemicals—primarily serotonin—that help regulate mood, anxiety, and compulsive thoughts. Clomipramine was one of the first medications approved specifically to treat obsessive-compulsive disorder (OCD), a condition where people experience unwanted, repetitive thoughts or behaviors they feel compelled to perform.
Beyond OCD, clomipramine is also used to treat major depressive disorder, panic disorder, and certain types of chronic pain. The medication may take 2-4 weeks before you notice full benefits, and it requires ongoing monitoring to ensure it's working safely for you. Generic clomipramine is chemically identical to brand-name Anafranil, offering the same therapeutic effects at a lower cost.

Side Effects
Clomipramine is generally well-tolerated, but like all medications, it can cause side effects. Most common side effects are mild and often decrease over the first few weeks of treatment as your body adjusts.
Common Side Effects
Dry mouth – Stay hydrated and consider sugar-free gum or lozenges to ease discomfort.
Drowsiness or sedation – This often improves with time; take your dose at night if your doctor agrees.
Constipation – Increase fiber intake, drink more water, and get regular physical activity to help manage this.
Blurred vision – Usually temporary; avoid driving if vision changes significantly.
Weight gain – Some people gain weight on clomipramine; discuss diet and exercise strategies with your doctor.
Dizziness – Rise slowly from sitting or lying down to reduce lightheadedness.
Serious Side Effects
Serotonin syndrome – A rare but serious condition caused by too much serotonin activity, with symptoms like high fever, muscle rigidity, and confusion.
Heart rhythm changes (arrhythmias) – Tricyclic antidepressants can affect heart electrical activity, especially at higher doses.
Severe allergic reaction – Rash, difficulty breathing, or swelling of the face may indicate a serious allergy.
Seizures – Clomipramine lowers seizure threshold, so those with seizure history need careful monitoring.
Angle-closure glaucoma – A sudden increase in eye pressure that causes severe pain and vision loss, most common in people with narrow angles in their eyes.
When to Seek Medical Attention
Contact your doctor if side effects persist beyond the first few weeks or become bothersome. Seek immediate emergency care if you experience chest pain, severe shortness of breath, signs of serotonin syndrome (fever, muscle stiffness, confusion), or thoughts of self-harm. If you have a personal or family history of heart disease, glaucoma, or seizures, inform your healthcare provider before starting clomipramine.

Important: Take clomipramine exactly as prescribed, usually once daily in the evening. Do not increase or decrease your dose without consulting your doctor. If you miss a dose, take it as soon as you remember unless it's close to your next dose—then skip the missed dose. Never stop taking clomipramine abruptly, as this can cause withdrawal symptoms like dizziness, electric shock sensations, and mood changes.
Drug Interactions
Clomipramine can interact with several medications and substances, potentially increasing side effects or reducing effectiveness. Always inform your healthcare provider about all medications, supplements, and herbal products you're taking.
SSRIs and SNRIs
Combining clomipramine with other serotonin-raising medications (like sertraline, fluoxetine, or venlafaxine) may cause serotonin syndrome. Your doctor may adjust doses or choose a different medication if both are necessary.
Monoamine Oxidase Inhibitors (MAOIs)
Using clomipramine with MAOIs can trigger a dangerous spike in blood pressure and serotonin syndrome. There must be a 2-week gap between stopping one class and starting the other.
CNS Depressants
Combining clomipramine with alcohol, benzodiazepines, or opioids increases drowsiness and impairs coordination. Avoid or limit alcohol, and use caution when driving or operating machinery.
Anticholinergic Medications
Combining clomipramine with anticholinergics (used for bladder control, allergies, or Parkinson's disease) may worsen dry mouth, constipation, and urinary retention.
Blood Pressure and Heart Medications
Clomipramine may lower blood pressure or interact with certain cardiac drugs, requiring dose adjustments or increased monitoring of your heart rate and blood pressure.
CYP450 Enzyme Inhibitors
Medications that inhibit liver enzymes (like cimetidine or certain antifungals) may increase clomipramine levels in your blood, raising the risk of side effects.

Frequently Asked Questions
Get answers to common questions about clomipramine and Anafranil.
Clomipramine typically begins showing effects within 2-4 weeks, though some people may notice improvements in sleep or anxiety sooner. For OCD specifically, full benefits may take 8-12 weeks. Patience is important—don't increase your dose or stop the medication early without consulting your doctor, as this disrupts the therapeutic process.
Yes, generic clomipramine contains the same active ingredient as Anafranil and must meet the same FDA standards for purity, strength, and effectiveness. Generic and brand-name drugs are chemically equivalent, though the inactive ingredients may differ slightly. Generic clomipramine costs significantly less while delivering identical therapeutic benefits.
Alcohol is not recommended while taking clomipramine because both increase drowsiness and impair judgment and coordination. Alcohol may also worsen depression and anxiety. If you choose to drink, limit it to small amounts and discuss your drinking habits with your doctor to ensure safety.
Take your missed dose as soon as you remember, unless it's almost time for your next scheduled dose. If it's nearly time for the next dose, skip the missed dose and continue with your regular schedule. Never take a double dose to make up for a missed one, as this increases side effect risk.
No—stopping clomipramine suddenly can cause withdrawal symptoms like dizziness, electric shock sensations, anxiety, and mood changes. Always work with your doctor to gradually taper your dose over several weeks if you need to stop the medication. A slow reduction minimizes withdrawal discomfort and allows your brain chemistry to readjust safely.
The Bottom Line
Anafranil (generic clomipramine) is a well-established tricyclic antidepressant with strong evidence for treating obsessive-compulsive disorder, depression, and anxiety disorders. While it has more side effects than newer antidepressants, many people benefit significantly from clomipramine, especially those who haven't responded to other medications. The generic version provides the same therapeutic benefits as the brand name at a fraction of the cost, making it an accessible option for long-term mental health management. Clomipramine requires patience—benefits take several weeks to appear—and regular medical monitoring to ensure safety and efficacy.
