Probenecid
About Probenecid
Probenecid is a prescription medicine primarily used to treat gout and gouty arthritis by lowering high levels of uric acid in the body. It is also prescribed alongside certain antibiotic treatments to help the body keep the antibiotic in the bloodstream longer, making the infection treatment more effective.
To get the best results, you must take this medicine consistently every day exactly as your doctor directs, even if you do not have active gout symptoms. It is highly recommended to take Probenecid with food or an antacid to prevent stomach upset, and you must drink plenty of water throughout the day. Making dietary changes, such as reducing purine-rich foods like red meat and seafood, can also help manage your condition.
While taking Probenecid, some people may experience mild side effects like a loss of appetite, nausea, or mild headaches. However, if you experience more serious issues such as severe lower back pain, blood in your urine, or signs of a severe allergic reaction, you should seek immediate medical attention.
Do not take this medicine if you have blood disorders, uric acid kidney stones, or if you are experiencing a sudden, acute gout attack. Talk to your doctor before starting this medicine if you have kidney disease, a history of stomach ulcers, or glucose-6-phosphate dehydrogenase (G6PD) deficiency.
This medicine can interact with alcohol, which can raise uric acid levels and trigger gout attacks, as well as pain relievers like aspirin, which can make this medicine less effective. If you are pregnant, breastfeeding, or are an elderly individual, consult your doctor to discuss whether this medicine is safe for your specific needs.
Uses of Probenecid
Medicinal Benefits
Probenecid provides several important health benefits. These benefits include:
- Prevention of painful gout flares: By keeping uric acid levels stable, Probenecid helps you avoid the sudden, intense joint pain and swelling associated with gout attacks, allowing for easier, pain-free movement.
- Protection against joint damage: Over time, high uric acid can cause permanent damage to your joints and tissues. This medicine helps dissolve existing crystal deposits and prevents new ones from forming, preserving your long-term joint health.
- Enhanced antibiotic effectiveness: When taken during an infection, it helps your prescribed antibiotics work longer and more powerfully in your system, supporting a faster and more complete recovery.

View AllDrug Warnings
- Watch for early gout flares: When you first start taking Probenecid, you may experience a temporary increase in gout attacks as old uric acid deposits begin to dissolve. Keep taking the medicine and talk to your doctor about temporary pain-relief options.
- Regular kidney tests: Your doctor will likely order regular blood and urine tests to monitor your kidney function and uric acid levels while you are on this medicine.
- Avoid aspirin: Do not take aspirin or other salicylates unless specifically directed by your doctor, as they can completely block the effects of this medicine.
- Do not start during a flare-up: If you are having a sudden, painful gout attack, do not start taking Probenecid until the acute attack has completely subsided.
- Check for dizziness: Since this medicine can cause dizziness in some individuals, avoid driving or operating machinery until you know how it affects you.
Drug Interactions
- Salicylates (like Aspirin): Can cancel out the uric-acid-lowering effects of Probenecid.
- NSAIDs (like Indomethacin, Naproxen, or Ketoprofen): Probenecid can slow down the removal of these pain relievers from your body, increasing their levels in your blood and raising the risk of side effects.
- Methotrexate: Taking these together can cause dangerous buildups of methotrexate in your body, increasing the risk of severe toxicity.
- Certain Antibiotics (like Penicillin or Cephalosporins): May stay in your system longer and at higher levels; while sometimes intentional, this requires close monitoring by your doctor.

Habit Forming
Diet & Lifestyle Advise
- Stay well-hydrated: Drink plenty of water (at least 2 to 3 litres daily) to help your kidneys flush out uric acid and prevent the formation of kidney stones.
- Limit purine-rich foods: Reduce your intake of foods that increase uric acid levels, such as red meats, organ meats (like liver), shellfish, and yeast extracts.
- Avoid alcohol and sugary drinks: Limit or avoid alcohol, especially beer, and drinks sweetened with high-fructose corn syrup, as these can trigger sudden gout attacks.
- Maintain a healthy weight: Gradually losing excess weight can help lower uric acid levels, but avoid extreme fasting or rapid weight loss diets, as these can temporarily raise uric acid and trigger gout flares.
Special Advise
Drink at least eight glasses of water or other fluids each day while taking Probenecid unless directed to do otherwise by your doctor. If you are a kidney patient, consult a doctor before fluid intake.
- The doctor will monitor your kidney function constantly before and while on treatment with Probenecid.
- A liver function test should be done regularly to monitor liver enzymes, as Probenecid can cause fluctuations.
- If you are undergoing a urine test, inform the lab technician or the doctor about the use of Probenecid.
Patients Concern
Disease/Condition Glossary
Gout: It is a type of inflammatory (allergic reaction) condition that forms uric acid crystals and accumulates inside feet, knuckles, and surrounding bone joints. This occurs due to high uric acid levels in the blood, resulting in immense pain in joints. The pain may be severe, but the condition improves with medication. To avoid bone and cartilage damage and weakening of the kidneys, repeated gout attacks can require long-term medication. In areas such as the wrists, elbows, feet, or earlobes, chronic gout sufferers can feel small hard lumps forming over time in the soft flesh. These deposits are concentrations of uric acid crystals, called tophi, and over time, can cause pain and stiffness.
FAQs
Probenecid is used to treat Gout (increased uric acid in joints).
Probenecid contains probenecid, primarily used to decrease blood uric acid levels in the body. It works by inhibiting the tubular reabsorption of urate, thus decreasing serum urate levels. It stops uric acid formation inside the body without affecting the essential mechanism of cells and the body.
The common side effects of Probenecid are stomach upset, diarrhea, nausea, skin rash, drowsiness, headache, vomiting, and loss of appetite. If you experience any of these side effects or have concerns, consult your doctor.
No, Probenecid should not be started during a sudden, painful gout attack, as it can actually make the flare-up worse. It is designed to prevent future attacks over the long term. If you have an active flare, talk to your doctor about fast-acting pain relief options first.
Generally, no. Aspirin and other salicylates can block Probenecid from working properly to lower your uric acid. If you need a pain reliever or take low-dose aspirin for your heart, talk to your doctor before taking them together.
This medicine works by forcing your kidneys to filter more uric acid out through your urine. Drinking plenty of water (10 to 12 glasses a day) dilutes your urine and prevents this excess uric acid from forming painful kidney stones. Talk to your pharmacist if you have questions about your daily fluid intake.
It is best to avoid or strictly limit alcohol, especially beer, while taking this medicine. Alcohol increases the production of uric acid in your body and decreases your kidneys' ability to remove it, which can trigger gout attacks and reduce the effectiveness of Probenecid. Talk to your doctor about safe lifestyle choices.
It is common to experience a temporary increase in gout attacks when you first start this medicine. Do not stop taking your medicine, as this is a sign that the drug is actively working to shift and clear out uric acid deposits. Talk to your doctor about safe anti-inflammatory medicines you can take to manage these early flares.
If you have moderate to severe kidney disease, Probenecid may not work effectively because it relies on healthy kidneys to clear uric acid from your blood. Before starting this medicine, talk to your doctor to check if your kidney function is sufficient for this treatment.
The safety of this medicine during pregnancy or breastfeeding is not fully established. If you are pregnant, planning to become pregnant, or are nursing, talk to your doctor to weigh the potential benefits against any risks before taking this medicine.
