Zyloprim

If you have been taking a drug that promotes the excretion of uric acid in the urine, such as probenecid (Benemid) or sulfinpyrazone (Anturane), to try to prevent attacks of gout, your doctor will probably want to reduce or stop your dosage of this drug while increasing your dosage of Zyloprim.

--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 cool, dry place, away from light.

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 Zyloprim.

Because a skin reaction, the most common side effect of Zyloprim, may occasionally become severe or even fatal, you should stop taking Zyloprim if you notice even the beginnings of a rash. Such a rash may be itchy or scaly or may make your skin peel off in sheets; it may be accompanied by chills and fever, aching joints, or jaundice.

• More common side effects may include:
  Acute attack of gout, diarrhea, nausea, rash

Why should Zyloprim not be prescribed?

Do not take Zyloprim if you have ever had a severe reaction to it in the past.

Special warnings about Zyloprim

If you notice a rash or other signs of an allergic reaction, stop taking Zyloprim immediately and consult your doctor. In some people, a Zyloprim-induced rash may lead to a serious skin disease, generalized inflammation of a blood or lymph vessel, irreversible liver damage, or even death.

You may experience acute attacks of gout more often in the early stages of Zyloprim therapy, even when normal uric acid levels have been attained. These attacks will become shorter and less severe after several months of therapy.

A kidney problem may turn a normal dose of Zyloprim into an overdose. If you have a kidney disease, or a condition such as diabetes or high blood pressure that may affect your kidneys, your doctor should prescribe Zyloprim cautiously and order periodic blood and urine tests to assess your kidney function.
