Zyloprim, also known by its generic name allopurinol, is a medication primarily used to treat gout and certain types of kidney stones. It belongs to a class of drugs called xanthine oxidase inhibitors, which work by reducing the production of uric acid in the body. Uric acid is a waste product that is normally excreted in urine, but in some individuals, high levels of uric acid can lead to the formation of crystals in the joints and kidneys, causing pain and inflammation.

Zyloprim is available in tablet form and is typically taken orally once or twice a day. The dosage prescribed can vary depending on the individual’s medical condition and response to treatment. It is important to follow the instructions provided by the healthcare professional and not exceed the recommended dose.


Before taking Zyloprim, it is crucial to inform your healthcare provider about any known allergies to allopurinol or any other medications. It is also essential to disclose your medical history, especially if you have or have had liver or kidney disease, heart problems, high blood pressure, or any blood disorders.

Zyloprim should not be used in individuals who have previously experienced a severe allergic reaction to allopurinol. It is also contraindicated in patients with a history of hypersensitivity to oxypurinol, the main metabolite of allopurinol.

Patients who are currently taking mercaptopurine or azathioprine, medications used to treat certain types of cancer or autoimmune disorders, should not take Zyloprim simultaneously. Concomitant use of Zyloprim with these drugs can increase the risk of adverse effects.

If you are pregnant or planning to become pregnant, it is important to discuss the potential risks and benefits of using Zyloprim with your healthcare provider. While there is limited information on the safety of Zyloprim during pregnancy, it should only be used if the potential benefits outweigh the potential risks.

Zyloprim Reactions

As with any medication, Zyloprim may cause side effects. Common side effects include nausea, vomiting, diarrhea, drowsiness, headache, and rash. These side effects are usually mild and temporary, but if they persist or worsen, it is important to contact your healthcare provider.

In some instances, serious side effects may occur. Seek immediate medical attention if you experience any of the following: severe allergic reactions (rash, itching, swelling, severe dizziness, difficulty breathing), signs of liver problems (persistent nausea/vomiting, yellowing of the eyes/skin, dark urine), or signs of a severe skin reaction (blistering, peeling, a rash that spreads).

While not common, Zyloprim can rarely cause a condition called Stevens-Johnson syndrome or toxic epidermal necrolysis. These are severe skin reactions that can be life-threatening. If you develop any signs or symptoms of these conditions, stop taking Zyloprim immediately and seek medical attention.

Taking Zyloprim Safely

It is important to take Zyloprim exactly as prescribed by your healthcare provider. Usually, the medication is taken once or twice daily, with or without food. It is recommended to drink plenty of fluids while taking Zyloprim to help prevent kidney stones.

If you miss a dose of Zyloprim, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

In case of an overdose, seek immediate medical attention or contact the local poison control center. Symptoms of an overdose may include severe dizziness, fainting, rapid/irregular heartbeat, or extreme tiredness.

What to Watch Out For

Zyloprim may interact with other medications, potentially increasing the risk of side effects or reducing the effectiveness of either drug. Inform your healthcare provider about all the medications, including over-the-counter drugs, herbal supplements, and vitamins, that you are currently taking.

Some medications that may interact with Zyloprim include diuretics, blood thinners (such as warfarin), and certain medications used to treat high blood pressure. Additionally, the use of Zyloprim in combination with other drugs that also lower the body’s ability to produce uric acid may increase the risk of developing kidney stones.

If you are scheduled to have surgery, inform your surgeon or anesthesiologist about your use of Zyloprim, as it may interact with certain anesthetics.
