Benemid (probenecid) is a uricosuric agent specifically formulated to support the management of chronic gout and gouty arthritis by enhancing the renal excretion of uric acid. By effectively lowering serum urate levels, it helps prevent the formation of tophi and reduces the frequency of acute gout attacks. This medication is often prescribed as part of a comprehensive treatment plan that includes lifestyle modifications and, where appropriate, anti-inflammatory agents. Its targeted mechanism makes it a cornerstone therapy for long-term urate control in eligible patients.
Features
- Active ingredient: Probenecid 500 mg
- Uricosuric action promotes renal excretion of uric acid
- Tablet formulation for oral administration
- Typically used in combination therapies for enhanced efficacy
- Requires gradual titration to optimal therapeutic dose
Benefits
- Reduces frequency and severity of acute gout attacks over time
- Lowers serum uric acid levels to help prevent joint damage
- May lead to the gradual resolution of existing tophi with sustained use
- Supports long-term management of chronic gout and hyperuricemia
- Can be used adjunctively with other agents like colchicine for comprehensive care
- Helps maintain renal function by preventing uric acid nephrolithiasis
Common use
Benemid is primarily indicated for the treatment of chronic gout and gouty arthritis in patients who experience frequent acute attacks or demonstrate visible tophi. It is also utilized in hyperuricemia associated with gout, particularly where urate overproduction or underexcretion is evident. In certain clinical scenarios, it may be employed to elevate and prolong plasma concentrations of penicillin-class antibiotics, though this application is less common in modern practice.
Dosage and direction
The initial adult dosage for gout management is 250 mg orally twice daily for one week, followed by an increase to 500 mg twice daily. Dosage may be further adjusted based on serum uric acid levels and clinical response, with maintenance doses typically ranging from 1–2 g daily in divided doses. Maximum recommended daily dose is 3 g. Administration should occur with meals or antacids to minimize gastrointestinal upset. Adequate hydration (8–10 glasses of fluid daily) is essential throughout therapy to reduce risk of uric acid stone formation.
Precautions
Regular monitoring of serum uric acid levels, renal function, and complete blood counts is advised during therapy. Use with caution in patients with history of peptic ulcer, renal impairment, or blood dyscrasias. May precipitate acute gout attacks during initial treatment; concurrent administration of colchicine or NSAIDs is often recommended during the first 3–6 months. Not recommended for treatment of asymptomatic hyperuricemia.
Contraindications
Hypersensitivity to probenecid or any component of the formulation; blood dyscrasias; uric acid kidney stones; children under 2 years of age; during acute gout attack (initiation phase); concomitant use with salicylates in doses greater than 325 mg daily.
Possible side effect
Common: headache, nausea, vomiting, anorexia, dizziness. Less common: urinary frequency, flushing, sore gums, hair loss. Rare: hypersensitivity reactions, anemia, leukopenia, nephrotic syndrome, hepatic necrosis. Gastrointestinal symptoms often diminish with continued therapy or dose adjustment.
Drug interaction
Significant interactions occur with: salicylates (decreased uricosuric effect), penicillin antibiotics (elevated concentrations), methotrexate (increased toxicity), NSAIDs (possible increased levels), oral hypoglycemics (enhanced effects), diazoxide (decreased efficacy), and acyclovir (increased risk of nephrotoxicity). Comprehensive medication review is essential before initiation.
Missed dose
If a dose is missed, take it as soon as remembered unless it is nearly time for the next scheduled dose. Do not double doses to make up for a missed administration. Maintain regular dosing schedule to ensure consistent uric acid control.
Overdose
Symptoms may include nausea, vomiting, dizziness, and convulsions. No specific antidote exists; treatment involves gastric lavage if recent ingestion, supportive care, and symptomatic management. Hemodialysis may be considered in severe cases though probenecid is highly protein-bound.
Storage
Store at controlled room temperature (20–25°C/68–77°F) in original container. Protect from light and moisture. Keep tightly closed and out of reach of children. Do not use after expiration date printed on packaging.

Reviews
“After six months of Benemid therapy, my uric acid levels normalized and I’ve had no acute attacks. Requires discipline with hydration but effective.” – Patient, 58 “Valuable adjunct in treatment-resistant gout cases. Requires careful patient selection and monitoring but delivers good long-term results when appropriately used.” – Rheumatologist, 12 years experience “Effective for prophylaxis though GI side effects were challenging initially. Dose adjustment and taking with food resolved most issues.” – Patient, 64 “Important historical agent that still has niche applications in modern rheumatology, particularly for patients intolerant to newer alternatives.” – Clinical Pharmacologist, 9 years experience
