Buy Zyrik 100mg (Allopurinol) Online
Zyrik 100mg is a prescription oral tablet containing 100mg of Allopurinol, a xanthine oxidase inhibitor used for the long-term management of gout, hyperuricaemia, and uric acid-related kidney stones. Zyrik 100mg is a cost-effective generic formulation that lowers serum uric acid levels by inhibiting its production, thereby preventing the crystal deposits in joints and soft tissues responsible for the painful acute gout attacks and chronic tophaceous gout. It is the most widely prescribed urate-lowering therapy globally and is the first-line agent for gout prevention according to international rheumatology guidelines.
What is Zyrik 100mg?
Zyrik 100mg is an oral tablet containing Allopurinol 100mg, a xanthine oxidase inhibitor that reduces uric acid synthesis in the body. It is indicated for the long-term prevention of gout attacks, the management of chronic hyperuricaemia (elevated uric acid), the dissolution of tophi, and the prevention of uric acid and calcium oxalate kidney stones. Zyrik 100mg is the initiating dose for most patients, particularly in those with renal impairment or those at risk of allopurinol hypersensitivity syndrome — the lowest effective dose is used and titrated upward based on serum uric acid response. It is a long-term medication — it does not treat acute gout attacks but reduces their frequency and severity over time. Allopurinol must never be started during an acute gout flare.
Manufacturer: Zyrik 100mg is manufactured by Sun Pharma, India’s largest pharmaceutical company, with a strong presence in rheumatology and metabolic disease medicine, producing high-quality generics to international standards.
Key Ingredients of Zyrik 100mg and Their Working Process
Allopurinol and its active metabolite, oxypurinol, are inhibitors of xanthine oxidase, the enzyme responsible for the final two steps in uric acid biosynthesis — converting hypoxanthine to xanthine, and xanthine to uric acid. By blocking this enzyme, Allopurinol reduces uric acid production, lowering serum urate concentrations. As serum uric acid levels fall below the saturation threshold (6 mg/dL), previously deposited monosodium urate crystals in joints and soft tissues begin to dissolve, reducing the burden of crystal-induced inflammation. The reduction in serum uric acid also prevents the formation of new crystals. Xanthine and hypoxanthine — the precursors that accumulate when xanthine oxidase is inhibited — are more soluble than uric acid and are safely excreted by the kidneys. The target serum uric acid level for effective gout management is below 6 mg/dL, or below 5 mg/dL in patients with tophi.
Clinical Uses of Allopurinol 100mg
Allopurinol 100mg is the initiating dose for long-term gout prophylaxis and hyperuricaemia management. Starting at 100mg allows the body to adapt and reduces the risk of allopurinol hypersensitivity syndrome in genetically susceptible patients. The dose is typically titrated upward at 4-to-8-week intervals — guided by serum uric acid monitoring — to a target maintenance dose of 200–300mg for mild gout, or up to 600–800mg for severe tophaceous gout. Allopurinol is also used in hyperuricaemia secondary to haematological malignancies or chemotherapy (tumour lysis syndrome prophylaxis) and in the prevention of recurrent calcium oxalate kidney stones in patients with hyperuricosuria.
Related strengths and products: Zyrik 300mg is available for patients who require higher maintenance doses for adequate serum uric acid control — the majority of gout patients ultimately require 300mg or more daily. Both Zyrik 100mg and Zyrik 300mg are stocked on AllDayChemist, allowing seamless dose escalation within the same product range. Febuxostat is an alternative xanthine oxidase inhibitor for patients who are intolerant of Allopurinol.
Key Benefits of Zyrik 100mg
Zyrik 100mg provides a safe, low-dose starting point for Allopurinol therapy, minimising the risk of hypersensitivity during treatment initiation while initiating serum uric acid reduction. Long-term Allopurinol therapy significantly reduces gout flare frequency, promotes tophus regression, and prevents joint damage from chronic hyperuricaemia. As a once-daily medication, it is easy to adhere to, and as a Sun Pharma generic, it delivers the full benefits of branded Allopurinol at a substantially lower cost.
Usage warnings and precautionary advice for using Allopurinol
Allopurinol hypersensitivity syndrome (AHS) is the most serious risk associated with Allopurinol — it manifests as a severe multi-system reaction including skin rashes (including Stevens-Johnson Syndrome and toxic epidermal necrolysis), fever, hepatitis, and renal failure. The HLA-B*5801 genetic variant strongly predicts AHS in patients of East and South-East Asian descent — genetic screening before initiating therapy is recommended in these populations. Any skin rash during Allopurinol use should prompt immediate cessation and medical review. Dose reduction is required in renal impairment; the dose should be proportional to creatinine clearance. Significant drug interactions include azathioprine and 6-mercaptopurine — Allopurinol dramatically increases their blood levels, risking life-threatening bone marrow suppression; these combinations are contraindicated or require major dose reduction under specialist supervision. Warfarin levels may also be increased.
Side effects of Allopurinol 100mg
Skin rashes are the most clinically important side effects, ranging from mild maculopapular eruptions to rare, life-threatening reactions. Any rash during treatment must be taken seriously, and the drug must be stopped. Gastrointestinal symptoms — nausea, vomiting, diarrhoea — are more common at higher doses and can be minimised by taking the tablet after food. Acute gout flares may occur at the start of treatment due to crystal mobilisation; this is expected and does not indicate treatment failure. Elevated liver enzymes and hepatitis have been reported rarely. Headache and drowsiness are occasionally described. Xanthine kidney stones are a rare theoretical concern at very high doses.

Proper dosage and usage guide of Allopurinol 100mg
Take one Zyrik 100mg tablet orally once daily, after meals, with a full glass of water — taking with food reduces the risk of gastrointestinal irritation. Drink plenty of fluids throughout the day (at least 2–3 litres) to maintain good urine output and reduce the risk of xanthine crystalluria. Do not start Allopurinol during an acute gout attack — wait until the flare has fully resolved for at least two to four weeks. Allopurinol initiation can paradoxically trigger a gout flare by mobilising existing urate deposits — prophylactic colchicine or an NSAID is often co-prescribed during the first 3–6 months of treatment. Have serum uric acid checked 4–6 weeks after starting therapy and after each dose change. Store at room temperature (15–30°C) in a dry, light-protected place.
What is Zyrik 100mg used for?
Zyrik 100mg (Allopurinol) is used to treat gout, high uric acid levels (hyperuricaemia), and uric acid kidney stones by reducing the body's production of uric acid.
How does Allopurinol in Zyrik 100mg work?
Allopurinol inhibits xanthine oxidase, the enzyme responsible for converting hypoxanthine and xanthine into uric acid, thereby reducing uric acid levels throughout the body.
When should I start Zyrik 100mg after a gout attack?
Do not start Allopurinol during an acute gout attack, as it can initially worsen flares. Begin treatment after the acute attack subsides, typically 2 to 4 weeks later.
How long does it take for Zyrik 100mg to lower uric acid?
Uric acid levels usually begin to fall within 1 to 2 weeks. Significant clinical benefit in preventing gout attacks typically takes 3 to 6 months of consistent use.
What are the side effects of Zyrik 100mg?
Common side effects include rash, nausea, and drowsiness. A severe skin reaction called Stevens-Johnson syndrome is rare but serious; stop the drug and seek care if a rash develops.
Can I drink alcohol while taking Zyrik 100mg?
Alcohol increases uric acid production and can trigger gout attacks. While not absolutely contraindicated, it is strongly advised to limit or avoid alcohol during Allopurinol therapy.
Can I buy Zyrik 100mg from AllDayChemist?
Yes. AllDayChemist stocks Zyrik 100mg at affordable prices. Order online with a valid prescription and benefit from genuine quality assurance and doorstep delivery.
Should Zyrik 100mg be taken with water?
Yes. Take each tablet with a full glass of water, and maintain adequate daily fluid intake (at least 2 litres) to help prevent kidney stone formation during uric acid reduction.
