Vivactil

Generic name: Protriptyline hydrochloride

Why is Vivactil prescribed?

Vivactil is used to treat the symptoms of mental depression in people who are under close medical supervision. It is particularly suitable for those who are inactive and withdrawn.

Vivactil is a member of the family of drugs called tricyclic antidepressants. Researchers don't know exactly how it works. Unlike the class of antidepressants known as monoamine oxidase (MAO) inhibitors, it does not act primarily through stimulation of the central nervous system. It tends to work more rapidly than some other tricyclic antidepressants. Improvement sometimes begins within a week.

Most important fact about Vivactil

If you are prone to anxiety or agitation, Vivactil can make the problem worse. It can also exaggerate the symptoms of manic-depression and schizophrenia. If this seems to be happening, let your doctor know immediately. The doctor may have to reduce the dose of Vivactil or add another drug to your regimen.

How should you take Vivactil?

Take Vivactil exactly as prescribed. Do not take it with alcohol.

• If you miss a dose...
  Take it 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 once.

• Storage instructions...
  Store at room temperature in a tightly closed container.

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 Vivactil.

• Side effects may include:
  Anxiety, blood disorders, confusion, decreased libido, dizziness, flushing, headache, impotence, insomnia, low blood pressure, nightmares, rapid or irregular heartbeat, rash, seizures, sensitivity to sunlight, stomach and intestinal problems

Why should Vivactil not be prescribed?

Due to the possibility of life-threatening side effects, Vivactil must never be taken with drugs classified as monoamine oxidase (MAO) inhibitors, such as the antidepressants Nardil and Parnate. Allow at least 14 days between the last dose of one of these drugs and the first dose of Vivactil.
