Zerit

Generic name: Stavudine

Why is Zerit prescribed?

Zerit is one of the drugs used to fight the human immunodeficiency virus (HIV)—the deadly cause of AIDS. It is usually prescribed for people who have already been taking the HIV drugs for an extended period. HIV attacks the immune system, slowly destroying the body's ability to fight off infection. Zerit helps stave off the attack by disrupting the virus's ability to reproduce.

Signs and symptoms of HIV infection include diarrhea, fever, headache, infections, problems with the nervous system, rash, sore throat, and significant weight loss.

Most important fact about Zerit

Although Zerit can slow the progress of HIV infection, it is not a cure. Because of the continuing danger of complications and infections, you should get frequent physical exams and blood counts. Be sure, too, to notify your doctor immediately if you experience any changes in your general health.

How should you take Zerit?

Take Zerit every 12 hours, exactly as prescribed. It's important to keep a constant level of the drug in the body, so be sure to take each dose on schedule. Do not take more than the prescribed amount; nerve disorders could result.

Shake the oral solution vigorously before measuring the dose.

You can take Zerit with or without food.

• 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...
  Keep the Zerit container tightly closed. Store the capsules at room temperature. Store Zerit oral solution in the refrigerator; throw out any unused medication after 30 days.

What side effects may occur?

Side effects are more likely if you combine Zerit with other drugs that cause similar reactions. Also, the higher your dosage of Zerit, the greater the chance of a problem. However, it's often hard to tell a side effect from a symptom of the disease. If you think the drug is causing problems, keep taking it until you've checked with your doctor. Only your doctor can determine whether the drug is at fault, and adjust your dosage accordingly.
