Your doctor may need to change the doses of your medications or monitor you carefully for side effects. If you become pregnant while taking allopurinol, call your doctor. Do not drive a car or operate machinery until you know how this medication affects you. Alcohol may decrease the effectiveness of allopurinol. What special dietary instructions should I follow? Drink at least eight glasses of water or other fluids each day while taking allopurinol unless directed to do otherwise by your doctor. What should I do if I forget a dose? Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule.
Do not take a double dose to make up for a missed one. What side effects can this medication cause? Allopurinol may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away: If progressive deposition of urates is to be arrested or reversed, it is necessary to reduce the serum uric acid level below the saturation point to suppress urate precipitation. Administration of Allopurinol generally results in a fall in both serum and urinary uric acid within 2 to 3 days. The degree of this decrease can be manipulated almost at will since it is dose-dependent. A week or more of treatment with Allopurinol may be required before its full effects are manifested; likewise, uric acid may return to pretreatment levels slowly usually after a period of 7 to 10 days following cessation of therapy.
This reflects primarily the accumulation and slow clearance of oxipurinol. In some patients a dramatic fall in urinary uric acid excretion may not occur, particularly in those with severe tophaceous gout. It has been postulated that this may be due to the mobilization of urate from tissue deposits as the serum uric acid level begins to fall. The action of Allopurinol differs from that of uricosuric agents, which lower the serum uric acid level by increasing urinary excretion of uric acid. Allopurinol reduces both the serum and urinary uric acid levels by inhibiting the formation of uric acid.
The use of Allopurinol to block the formation of urates avoids the hazard of increased renal excretion of uric acid posed by uricosuric drugs. Allopurinol can substantially reduce serum and urinary uric acid levels in previously refractory patients even in the presence of renal damage serious enough to render uricosuric drugs virtually ineffective. Salicylates may be given conjointly for their antirheumatic effect without compromising the action of Allopurinol. This is in contrast to the nullifying effect of salicylates on uricosuric drugs. Allopurinol also inhibits the enzymatic oxidation of mercaptopurine, the sulfur-containing analogue of hypoxanthine, to 6-thiouric acid.
This oxidation, which is catalyzed by xanthine oxidase, inactivates mercaptopurine. Allopurinol tablets, USP reduces serum and urinary uric acid concentrations. Allopurinol tablets, USP are indicated in: Treatment with Allopurinol tablets, USP should be discontinued when the potential for overproduction of uric acid is no longer present. Therapy in such patients should be carefully assessed initially and reassessed periodically to determine in each case that treatment is beneficial and that the benefits outweigh the risks. Contraindications Patients who have developed a severe reaction to Allopurinol tablets, USP should not be restarted on the drug.
A few cases of reversible clinical hepatotoxicity have been noted in patients taking Allopurinol, and in some patients, asymptomatic rises in serum alkaline phosphatase or serum transaminase have been observed. If anorexia, weight loss, or pruritus develop in patients on Allopurinol, evaluation of liver function should be part of their diagnostic workup. In patients with pre-existing liver disease, periodic liver function tests are recommended during the early stages of therapy. Due to the occasional occurrence of drowsiness, patients should be alerted to the need for due precaution when engaging in activities where alertness is mandatory. The occurrence of hypersensitivity reactions to Allopurinol may be increased in patients with decreased renal function receiving thiazides and Allopurinol concurrently.
For this reason, in this clinical setting, such combinations should be administered with caution and patients should be observed closely. Precautions General: An increase in acute attacks of gout has been reported during the early stages of administration of Allopurinol, even when normal or subnormal serum uric acid levels have been attained. Accordingly, maintenance doses of colchicine generally should be given prophylactically when Allopurinol is begun. The use of colchicine or anti-inflammatory agents may be required to suppress gouty attacks in some cases.
The attacks usually become shorter and less severe after several months of therapy. The mobilization of urates from tissue deposits which cause fluctuations in the serum uric acid levels may be a possible explanation for these episodes. Even with adequate therapy with Allopurinol, it may require several months to deplete the uric acid pool sufficiently to achieve control of the acute attacks. A fluid intake sufficient to yield a daily urinary output of at least 2 liters and the maintenance of a neutral or, preferably, slightly alkaline urine are desirable to 1 avoid the theoretical possibility of formation of xanthine calculi under the influence of therapy with Allopurinol and 2 help prevent renal precipitation of urates in patients receiving concomitant uricosuric agents.
Some patients with pre-existing renal disease or poor urate clearance have shown a rise in BUN during administration of Allopurinol. Although the mechanism responsible for this has not been established, patients with impaired renal function should be carefully observed during the early stages of administration of Allopurinol and the dosage decreased or the drug withdrawn if increased abnormalities in renal function appear and persist. Renal failure in association with administration of Allopurinol has been observed among patients with hyperuricemia secondary to neoplastic diseases. Concurrent conditions such as multiple myeloma and congestive myocardial disease were present among those patients whose renal dysfunction increased after Allopurinol was begun.
Renal failure is also frequently associated with gouty nephropathy and rarely with hypersensitivity reactions associated with Allopurinol. Albuminuria has been observed among patients who developed clinical gout following chronic glomerulonephritis and chronic pyelonephritis. Patients with decreased renal function require lower doses of Allopurinol than those with normal renal function. Lower than recommended doses should be used to initiate therapy in any patients with decreased renal function and they should be observed closely during the early stages of administration of Allopurinol.
In patients with severely impaired renal function or decreased urate clearance, the half-life of oxipurinol in the plasma is greatly prolonged. Therefore, a dose of 100 mg per day or 300 mg twice a week, or perhaps less, may be sufficient to maintain adequate xanthine oxidase inhibition to reduce serum urate levels. Bone marrow depression has been reported in patients receiving Allopurinol, most of whom received concomitant drugs with the potential for causing this reaction. This has occurred as early as 6 weeks to as long as 6 years after the initiation of therapy of Allopurinol.
Rarely, a patient may develop varying degrees of bone marrow depression, affecting one or more cell lines, while receiving Allopurinol alone. Information for Patients: Patients should be informed of the following: Laboratory Tests: The correct dosage and schedule for maintaining the serum uric acid within the normal range is best determined by using the serum uric acid as an index. Allopurinol and its primary active metabolite, oxipurinol, are eliminated by the kidneys; therefore, changes in renal function have a profound effect on dosage.
In patients with decreased renal function or who have concurrent illnesses which can affect renal function such as hypertension and diabetes mellitus, periodic laboratory parameters of renal function, particularly BUN and serum creatinine or creatinine clearance, should be performed and the patient's dosage of Allopurinol reassessed. The prothrombin time should be reassessed periodically in the patients receiving dicumarol who are given Allopurinol. Drug Interactions: In patients receiving mercaptopurine or IMURAN azathioprine , the concomitant administration of 300 to 600 mg of Allopurinol per day will require a reduction in dose to approximately one third to one fourth of the usual dose of mercaptopurine or azathioprine.
It has been reported that Allopurinol prolongs the half-life of the anticoagulant, dicumarol. The clinical basis of this drug interaction has not been established but should be noted when Allopurinol is given to patients already on dicumarol therapy. Since the excretion of oxipurinol is similar to that of urate, uricosuric agents, which increase the excretion of urate, are also likely to increase the excretion of oxipurinol and thus lower the degree of inhibition of xanthine oxidase. The concomitant administration of uricosuric agents and Allopurinol has been associated with a decrease in the excretion of oxypurines hypoxanthine and xanthine and an increase in urinary uric acid excretion compared with that observed with Allopurinol alone.
Allopurinol is usually prescribed anywhere between 50mg to 900mg depending obviously on the severity and common allopurinol gout treatment dosage is usually 300mg a day. It is imperative that you have regular uric acid tests while on this treatment and to ensure that the prescribed dosage is right for you. The medication is taken orally, at the same time every day and after a meal to reduce stomach upset. It is advisable to drink a full glass of water with each dose and recommended for the gout sufferer to at least drink 8 to 12 glasses of water a day unless your doctor has directed you to drink less fluids for other medical reasons.
The weird part about taking allopurinol is that in the beginning ,it may increase the number of gout attacks cause it can take up to several weeks for this drug to take effect. It is common for the starting dose of allopurinol to be low and gradually increased. Eventually, allopurinol will do its job and keep your uric acid at a healthy level and prevent any further gout attacks. What are the side effects of allopurinol? Rash is one of the more common side effects and can occur even after months or years of treatment with allopurinol. Rarer side effects that are more severe if they do occur include the following:
8/2/ · If you get a gout attack (often called gout flare) while you are taking allopurinol, you must continue. Missing a dose will do nothing to make the pain go away – it will just prolong the length of time that you have uric acid crystals in your body. But that does not completely answer the question, “Can I stop taking allopurinol?”. Tough if you can’t go on Uloric, best to seek the advice of another rheumatologist and take it from there. Maybe a daily colchicine tablet instead or further splitting of the allopurinol throughout the day. Eventually your stomach can get used to it and you can take your dose ulols.com: Spiro Koulouris. Allopurinol can lower the urate levels in your blood over the space of a few weeks. This will stop new crystals forming. It can take longer to dissolve crystals that are already there, and you may have more attacks of gout during this time. This is more likely to happen if your urate levels are very high or you’ve had gout for a long time.

Rare reports indicate that cyclosporine levels may be increased during concomitant treatment with Allopurinol. Monitoring of cyclosporine levels and possible adjustment of cyclosporine dosage should be considered when these drugs are co-administered. Allopurinol is not known to alter the accuracy of laboratory tests. Pregnancy Teratogenic Effects: There were increased numbers of external malformations in fetuses at both doses of Allopurinol on gestation day 10 and increased numbers of skeletal malformations in fetuses at both doses on gestation day 13. It cannot be determined whether this represented a fetal effect or an effect secondary to maternal toxicity. There are, however, no adequate or well-controlled studies in pregnant women.
Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Experience with Allopurinol during human pregnancy has been limited partly because women of reproductive age rarely require treatment with Allopurinol. However, in 2011, a literature publication case report describes the outcome of a full term pregnancy in a 35 year-old woman who had recurrent kidney stones since age 18 who took Allopurinol throughout the pregnancy. The child had multiple complex birth defects and died at 8 days of life. The overall rate of major fetal malformations and spontaneous abortions was reported to be within the normal expected range; however, one child had severe malformations similar to those described in the cited earlier case report.
Nursing Mothers: Allopurinol and oxipurinol have been found in the milk of a mother who was receiving Allopurinol. Since the effect of Allopurinol on the nursing infant is unknown, caution should be exercised when Allopurinol is administered to a nursing woman. Pediatric Use: Adverse Reactions Data upon which the following estimates of incidence of adverse reactions are made are derived from experiences reported in the literature, unpublished clinical trials and voluntary reports since marketing of Allopurinol began. The most frequent adverse reaction to Allopurinol is skin rash.
Skin reactions can be severe and sometimes fatal. Some patients with the most severe reaction also had fever, chills, arthralgias, cholestatic jaundice, eosinophilia and mild leukocytosis or leukopenia. The explanation for this decrease is not obvious. The incidence of skin rash may be increased in the presence of renal insufficiency. The syndrome includes many of the severe reactions described above, and is potentially life-threatening and fatal. The syndrome is often characterized by fever, severe and profuse skin rash, elevated leukocyte counts and in particular, elevated eosinophil counts, lymphadenopathy, and multi-organ pathologies. Systemic symptoms often included, but were not limited to, the hepatic and renal systems.
Symptoms involving the cardiac, gastrointestinal, lymphatic, pulmonary, and ophthalmic systems were also reported as occurring as part of the syndrome. It has been reported that symptoms may develop in approximately 1 week from initiating Allopurinol therapy, but longer latency periods have also been reported. Metabolic and Nutritional: Acute attacks of gout. Skin and Appendages: Rash, maculopapular rash. The most frequent event observed was acute attacks of gout following the initiation of therapy.

In the management of overdosage there is no specific antidote for Allopurinol. There has been no clinical experience in the management of a patient who has taken massive amounts of Allopurinol. Both Allopurinol and oxipurinol are dialyzable; however, the usefulness of hemodialysis or peritoneal dialysis in the management of an overdose of Allopurinol is unknown. Allopurinol Dosage and Administration The dosage of Allopurinol tablets to accomplish full control of gout and to lower serum uric acid to normal or near-normal levels varies with the severity of the disease. The appropriate dosage may be administered in divided doses or as a single equivalent dose with the 300 mg-tablet.
Dosage requirements in excess of 300 mg should be administered in divided doses. The minimal effective dosage is 100 to 200 mg daily and the maximal recommended dosage is 800 mg daily. Normal serum urate levels are usually achieved in 1 to 3 weeks. Too much reliance should not be placed on a single serum uric acid determination since, for technical reasons, estimation of uric acid may be difficult. How should I take allopurinol? 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.
Take each dose with a full glass of water. To reduce your risk of kidney stones forming, drink 8 to 10 full glasses of fluid every day, unless your doctor tells you otherwise. Take with food if allopurinol upsets your stomach. You may have gout attacks more often when you first start taking allopurinol. Your doctor may recommend other gout medication to take at this time. Keep using your medication as directed and tell your doctor if your symptoms do not improve after 6 weeks of treatment. The medication is taken orally, at the same time every day and after a meal to reduce stomach upset.
It is advisable to drink a full glass of water with each dose and recommended for the gout sufferer to at least drink 8 to 12 glasses of water a day unless your doctor has directed you to drink less fluids for other medical reasons. The weird part about taking allopurinol is that in the beginning ,it may increase the number of gout attacks cause it can take up to several weeks for this drug to take effect. It is common for the starting dose of allopurinol to be low and gradually increased. Eventually, allopurinol will do its job and keep your uric acid at a healthy level and prevent any further gout attacks.
What are the side effects of allopurinol? Rash is one of the more common side effects and can occur even after months or years of treatment with allopurinol. Rarer side effects that are more severe if they do occur include the following: The question is are you one of those gout sufferers who actually sticks with your allopurinol therapy? Poor adherence is understandable.
