Why is Anafranil prescribed?
Anafranil, a chemical cousin of tricyclic antidepressant medications such as Tofranil and Elavil, is used to treat people who suffer from obsessions and compulsions.
An obsession is a persistent, disturbing idea, image, or urge that keeps coming to mind despite the person's efforts to ignore or forget it--for example, a preoccupation with avoiding contamination.
A compulsion is an irrational action that the person knows is senseless but feels driven to repeat again and again--for example, hand-washing perhaps dozens or even scores of times throughout the day.
Most important fact about Anafranil
Serious, even fatal, reactions have been known to occur when drugs such as Anafranil are taken along with drugs known as MAO inhibitors. Drugs in this category include the antidepressants Nardil and Parnate. Never take Anafranil with one of these drugs.
How should you take Anafranil?
Take Anafranil with meals, at first, to avoid stomach upset. After your regular dosage has been established, you can take 1 dose at bedtime to avoid sleepiness during the day. Always take it exactly as prescribed.
This medicine may cause dry mouth. Hard candy, chewing gum, or bits of ice may relieve this problem.
--If you miss a dose...
If you take 1 dose at bedtime, consult your doctor. Do not take the missed dose in the morning. If you take 2 or more doses a day, take the missed dose as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take 2 doses at the same time.
--Storage instructions...
Store at room temperature in a tightly closed container, away from moisture.
What side effects may occur?
Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Anafranil.
The most significant risk is that of seizures (convulsions). Headache, fatigue, and nausea can be a problem. Men are likely to experience problems with sexual function. Unwanted weight gain is a potential problem for many people who take Anafranil, although a small number actually lose weight.
• More common side effects may include:
Constipation, dizziness, dry mouth, impotence, increased appetite, increased sweating, indigestion, libido changes, nausea, nervousness, sleepiness, tremor, twitching, visual changes, weight gain, weight loss
Why should Anafranil not be prescribed?
Do not take Anafranil if you are sensitive to or have ever had an allergic reaction to a tricyclic antidepressant such as Tofranil, Elavil, or Tegretol.
Be sure to avoid Anafranil if you are taking, or have taken within the past 14 days, an MAO inhibitor such as the antidepressants Parnate or Nardil. Combining Anafranil with one of these medications could lead to fever, seizures, coma, and even death.
Do not take Anafranil if you have recently had a heart attack.
Special warnings about Anafranil
This drug should be used with caution in children with depression. In clinical studies, antidepressants increased the risk of suicidal thinking and behavior in children and adolescents with depression and other psychiatric disorders. Anyone considering the use of Anafranil or any other antidepressant in a child or adolescent must balance this risk with the clinical need. In children, Anafranil is only approved to treat obsessive-compulsive disorder.
Additionally, the progression of major depression is associated with a worsening of symptoms and/or the emergence of suicidal thinking or behavior in both adults and children, whether or not they are taking antidepressants. Individuals being treated with Anafranil and their caregivers should watch for any change in symptoms or any new symptoms that appear suddenly--especially agitation, anxiety, hostility, panic, restlessness, extreme hyperactivity, and suicidal thinking or behavior--and report them to the doctor immediately. Be especially observant at the beginning of treatment or whenever there is a change in dose.
If you have narrow-angle glaucoma (increased pressure in the eye) or are having difficulty urinating, Anafranil could make these conditions worse. Use Anafranil with caution if your kidney function is not normal.
If you have a tumor of the adrenal gland, Anafranil could cause your blood pressure to rise suddenly and dangerously.
Because Anafranil poses a possible risk of seizures, and because it may impair mental or physical ability to perform complicated tasks, your doctor will probably warn you to take special precautions if you need to drive a car, operate complicated machinery, or take part in activities such as swimming or climbing, in which suddenly losing consciousness could be dangerous. Note that your risk of seizures is increased:
• If you have ever had a seizure
• If you have a history of brain damage or alcoholism
• If you are taking another medication that might predispose you to seizures
As with Tofranil, Elavil, and other tricyclic antidepressants, an overdose of Anafranil can be fatal. Do not be surprised if your doctor prescribes only a small quantity of Anafranil at a time. This is standard procedure to minimize the risk of overdose.
Anafranil may cause your skin to become more sensitive to sunlight. Avoid prolonged exposure to sunlight.
Before having any kind of surgery involving the use of general anesthesia, tell your doctor or dentist that you are taking Anafranil. You may be advised to discontinue the drug temporarily.
When it is time to stop taking Anafranil, do not stop abruptly. Your doctor will have you taper off gradually to avoid withdrawal symptoms such as dizziness, fever, general feeling of illness, headache, high fever, irritability or worsening emotional or mental problems, nausea, sleep problems, vomiting.
Possible food and drug interactions when taking Anafranil
Avoid alcoholic beverages while taking Anafranil.
If Anafranil is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Anafranil with the following:
Antipsychotic drugs such as Haldol and chlorpromazine
Barbiturates such as phenobarbital
Certain blood pressure drugs such as Ismelin and Catapres-TTS
Cimetidine (Tagamet)
Digoxin (Lanoxin)
Drugs that ease spasms, such as Donnatal, Cogentin, and Bentyl
Flecainide (Tambocor)
Methylphenidate (Ritalin)
MAO inhibitors such as Nardil and Parnate
Phenytoin (Dilantin)
Propafenone (Rythmol)
Quinidine (Quinidex)
Serotonin-boosting drugs such as the antidepressants Luvox, Paxil, Prozac and Zoloft
Thyroid medications such as Synthroid
Tranquilizers such as Xanax and Valium
Warfarin (Coumadin)
Special information if you are pregnant or breastfeeding
If you are pregnant or plan to become pregnant, inform your doctor immediately. Anafranil should not be used during pregnancy unless absolutely necessary; some babies born to women who took Anafranil have had withdrawal symptoms such as jitteriness, tremors, and seizures. Anafranil appears in breast milk. Your doctor may advise you to stop breastfeeding while you are taking Anafranil.

After the dose has been determined, your doctor may direct you to take a single dose at bedtime, to avoid sleepiness during the day.
