Probenecid
Summary
Probenecid is primarily used to treat chronic gout and gouty arthritis. It helps in increasing the excretion of uric acid through the kidneys, thereby reducing serum urate levels. It is also used to enhance the effectiveness of certain antibiotics by preventing their excretion in urine, thus maintaining higher plasma levels.
Probenecid works by inhibiting the reabsorption of urate in the renal tubules. This increases the urinary excretion of uric acid and decreases serum urate levels. This action helps reduce the miscible urate pool, retards urate deposition, and promotes the resorption of urate deposits, effectively managing conditions like gout.
For adults, the usual daily dose of Probenecid for treating gout is 250 mg twice a day for one week, followed by 500 mg twice a day. For children aged 2 to 14 years, the initial dose is 25 mg/kg body weight with a maintenance dose of 40 mg/kg body weight per day divided into 4 doses. Probenecid is contraindicated in children under 2 years of age.
Common side effects of Probenecid include headache, upset stomach, vomiting, and dizziness. Serious adverse effects can include severe skin rash, difficulty breathing, and unusual bleeding or bruising. Patients should report any severe or persistent side effects to their healthcare provider immediately.
Important warnings for Probenecid include the potential for exacerbation of gout attacks when starting therapy, hypersensitivity reactions, and interactions with other medications like methotrexate and salicylates. Contraindications include hypersensitivity to Probenecid, children under 2 years, and individuals with blood dyscrasias or uric acid kidney stones. Therapy should not start during an acute gout attack.
Indications and Purpose
How does Probenecid work?
Probenecid works by blocking the reabsorption of uric acid in the kidneys, which increases its excretion in urine. Think of it like a filter that helps remove excess uric acid from your body. This process lowers uric acid levels in the blood, reducing the risk of gout attacks. Probenecid is effective for people with gout and hyperuricemia.
Is Probenecid effective?
Probenecid is effective in treating gout and hyperuricemia, which is high uric acid levels in the blood. It works by helping your kidneys remove uric acid, reducing the risk of gout attacks. Clinical studies show Probenecid effectively lowers uric acid levels and decreases the frequency of gout attacks. Always follow your doctor's instructions for the best results.
What is Probenecid?
Probenecid is a medication used to treat gout and hyperuricemia, which is high uric acid levels in the blood. It belongs to a class of drugs called uricosurics, which help your kidneys remove uric acid from your body. By lowering uric acid levels, Probenecid reduces the risk of gout attacks. It's often used in combination with other therapies for better management of gout.
Directions for Use
For how long do I take Probenecid?
Probenecid is usually a long-term medication for managing conditions like gout. You'll typically take it every day as a lifelong treatment unless your doctor suggests otherwise.

How long does it take for Probenecid to start working?
Probenecid begins working in your body shortly after you take it, but it may take several weeks to achieve its full therapeutic effect. You might notice a reduction in gout attacks and lower uric acid levels over time. How quickly the medication works can depend on your overall health and kidney function. Take it exactly as prescribed for the best results.
How should I store Probenecid?
Store Probenecid at room temperature, away from moisture and light. Keep it in a tightly closed container. Don't store it in humid places like bathrooms.
