Stevens-Johnson syndrome is a rare side effect of allopurinol. It causes flu-like symptoms, followed by a red or purple rash that spreads and forms blisters. The affected skin eventually dies and peels off.
It's more likely to happen in the first 8 weeks of taking allopurinol, or when the dose is increased too quickly. It can also happen if allopurinol is stopped suddenly for a few days and then restarted at the same dose as before. It's better to reduce the dose and then increase it slowly.
To help prevent the chance of you getting a rash that could be confused with Stevens-Johnson syndrome, it's best not to try new medicines or food during the first 3 months of treatment with allopurinol.
Your doctor may prescribe an NSAID (such as diclofenac or naproxen) or a medicine called colchicine to help prevent or to deal with attacks of gout \u2013 especially in the early stages of allopurinol treatment.
There's not enough information to say whether complementary medicines, herbal remedies and supplements are safe to take with allopurinol. They are not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
Allopurinol comes as a tablet to take by mouth. It is usually taken once or twice a day, preferably after a meal. To help you remember to take allopurinol, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take allopurinol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
It may take several months or longer before you feel the full benefit of allopurinol. Allopurinol may increase the number of gout attacks during the first few months that you take it, although it will eventually prevent attacks. Your doctor may prescribe another medication such as colchicine to prevent gout attacks for the first few months you take allopurinol. Continue to take allopurinol even if you feel well. Do not stop taking allopurinol without talking to your doctor.
Allopurinol may rarely cause very serious (possibly fatal) skin reactions. Some people in certain ethnic groups (such as people of African, Asian, or Native Hawaiian/Pacific Islander descent) are at greater risk. Your doctor may order a blood test to measure your risk before you start this medication. If the blood test shows you are at greater risk, your doctor should discuss the risks and benefits of allopurinol and other treatment choices with you. Get medical help right away if you develop any symptoms of a serious skin reaction, including: skin rash/blisters/peeling, itching, or swelling. Ask your doctor or pharmacist for more details.

Allopurinol prescription medication, like febuxostat (Uloric), is a xanthine oxidase enzyme inhibitor medication that is sometimes marketed under the brand name Zyloprim. Allopurinol is used for managing patients with signs of primary or secondary gout, certain patients with leukemia and lymphoma, and some patients with recurrent calcium oxalate calculi and high uric acid excretion. Gout is a disorder of the metabolism (hyperuricemia) that is characterized by the deposition of monosodium urate in tissues such as the joints. Allopurinol medication works by reducing the production of uric acid by acting on purine catabolism. Similar to the purine base hypoxanthine, allopurinol inhibits the enzymatic activity of xanthine oxidase and interferes with the conversion of xanthine to uric acid. Serum and urinary uric acid levels are typically observed to drop within three days of allopurinol administration and depends on the dose of allopurinol given. Allopurinol medication is sometimes used with colchicine (Colcrys, Mitigare), indomethacin (Indocin) and probenecid in gout patients.
Allopurinol is orally administered and is available as allopurinol 100 mg and allopurinol 300 mg tablets. Allopurinol is 90% absorbed from the gastrointestinal tract and peak plasma levels occur in as quickly as 1.5 hours. A small percentage of allopurinol is excreted in the feces. Allopurinol is available at many pharmacies for a reasonable cost. Allopurinol typically costs under twenty cents per pill and, in some cases, the cost may be partially or fully covered by one's insurance plan. Allopurinol coupons may also be available online which can help reduce the cost even further.
Allopurinol OTC is not available in the US as allopurinol is a prescription medication. As such, one cannot simply buy allopurinol online. However, Push Health can help people in need of an allopurinol prescription connect with a licensed provider who can prescribe allopurinol medication, including generic allopurinol 100 mg tablets and allopurinol 300 mg tablets, when appropriate to do so.
People who plan to use allopurinol prescription medication should be aware of possible side effects. Side effects of allopurinol use include, but are not limited to, diarrhea, nausea, liver inflammation, acute attacks of gout and a rash. Allopurinol medication should not be used for treating asymptomatic hyperuricemia. People who have a hypersensitivity or allergy to allopurinol medication should not use the medication. It is not recommended to drink alcohol while using allopurinol. Questions about allopurinol prescription tablets and its side effects should be discussed with the pharmacist and medical provider prior to use.
You should not use this medicine if you have ever had a serious allergic reaction to allopurinol. Stop taking the medicine and call your doctor at once if you have any signs of skin rash (no matter how mild), painful urination, blood in your urine, burning in your eyes, or swelling in your face or throat.
Stop using this medicine and get emergency medical help if you have signs of an allergic reaction to allopurinol (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).
Take allopurinol exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
This list is not complete. Other drugs may interact with allopurinol, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
Your doctor may recommend that you do not start taking allopurinol until after an attack of gout has passed to avoid triggering further attacks. If this is not possible, it may be started when your inflammation is not too bad.
To reduce the effects of gout attacks in the first three to six months of taking allopurinol, your doctor may prescribe a low dose of colchicine or a non-steroidal anti-inflammatory drug (NSAID), such as:
If you develop a rash, redness or flu-like symptoms, you should contact your doctor straight away. If you become dizzy or drowsy while taking allopurinol, do not drive or operate machinery, and see your doctor as soon as possible. You should also speak to your doctor if you develop any new symptoms that worry you.
Allopurinol is known chemically as 1,5-dihydro-4 H-pyrazolo [3,4- d]pyrimidin-4-one. It is a xanthine oxidase inhibitor which is administered orally. Each white to off white tablet contains 100 mg or 300 mg of allopurinol and the inactive ingredients lactose, crospovidone, magnesium stearate, maize starch, and povidone. Its solubility in water at 37C is 80.0 mg/dL and is greater in an alkaline solution.
It has been shown that reutilization of both hypoxanthine and xanthine for nucleotide and nucleic acid synthesis is markedly enhanced when their oxidations are inhibited by allopurinol and oxipurinol. This reutilization does not disrupt normal nucleic acid anabolism, however, because feedback inhibition is an integral part of purine biosynthesis. As a result of xanthine oxidase inhibition, the serum concentration of hypoxanthine plus xanthine in patients receiving allopurinol for treatment of hyperuricemia is usually in the range of 0.3 to 0.4 mg/dL compared to a normal level of approximately 0.15 mg/dL. A maximum of 0.9 mg/dL of these oxypurines has been reported when the serum urate was lowered to less than 2 mg/dL by high doses of allopurinol. These values are far below the saturation levels at which point their precipitation would be expected to occur (above 7 mg/dL).
Allopurinol is approximately 90% absorbed from the gastrointestinal tract. Peak plasma levels generally occur at 1.5 hours and 4.5 hours for allopurinol and oxipurinol respectively, and after a single oral dose of 300 mg allopurinol, maximum plasma levels of about 3 mcg/mL of allopurinol and 6.5 mcg/mL of oxipurinol are produced. 041b061a72
