probenecid
Probenecid is commonly used to prevent gout attacks in the long run, but it doesn't help relieve pain and swelling during a sudden gout attack. It's also sometimes used with certain antibiotics, such as penicillin, to boost their ability to fight infections. Probenecid comes as tablets that are taken by mouth twice daily for gout. Some side effects of this medication include headache, dizziness, and sometimes kidney stones. Probenecid might also have a few interactions with other medications.
What is Probenecid?
What is Probenecid used for?
- Gout (joint pain and swelling caused by high uric acid levels)
- Boosting antibiotic activity to fight infections
How Probenecid works
Probenecid is an antigout medication. Gout is a form of joint pain and swelling caused by high uric acid levels in your body. Probenecid works in your kidney to get rid of extra uric acid in the body. It helps move the extra uric acid into your urine so you can urinate it out. This helps lower the uric acid levels in your body to treat gout.
Probenecid also blocks the kidney from getting rid of certain antibiotics. As a result, the antibiotics stay in your body for a longer period of time, and their ability to fight infections gets boosted.

Pros and cons of Probenecid
Pros
- Helps treat the cause of gout
- Can use for children 2 years and older (for treatment of infections with certain antibiotics only)
- Available as a lower-cost generic medication
Cons
- Not a first-choice option for gout
- Can't take aspirin at the same time because it might raise the risk for a gout attack
- Might not work as well for people with severe kidney problems
Pharmacist tips for Probenecid
- Drink plenty of water while taking probenecid. Being well hydrated helps prevent kidney stones that might form during treatment.
- If you're having a gout attack and you haven't started your probenecid treatment yet, wait until you're feeling better to start the medication. Probenecid doesn't work well to relieve sudden, sharp pain and swelling in your joints.
- Gout attacks can happen when you first start taking probenecid. If you have an attack while taking probenecid, continue the medication at the same dose. Make sure to talk to your healthcare provider about taking additional medication (e.g., ibuprofen (Advil), colchicine (Colcrys)) that can treat these gout attacks.
- If you're still having gout attacks after using probenecid for a while, speak with your provider. They might order a blood test to check your uric acid levels. If your levels are still high, your provider might raise your dose of probenecid or they might switch you to different medication to help treat gout.
- Don't take aspirin (325 mg or 81 mg) with probenecid. Aspirin can make probenecid not work as well to get rid of uric acid from your body. As a result, taking aspirin with probenecid can raise your risk of gout attacks. Ask your provider for alternatives for aspirin or probenecid.
- Let your provider know about all the medications you're taking or planning to take. They can make sure they're safe for you to take with probenecid. Probenecid can block the kidney from getting rid of certain medications, such as methotrexate, from your body. This might raise your risk of side effects from these medications.
Risks and warnings for Probenecid
Probenecid can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Kidney stones
It's possible to get kidney stones while you're taking probenecid for gout. Make sure to drink plenty of water each day during treatment. Let your healthcare provider know if you have severe back pain, stomach pain, blood in your urine, or fever and chills. These symptoms might mean you have a kidney stone.
Risk of blood problems in certain people
- Risk factors: Glucose-6-phosphate dehydrogenase (G6PD) deficiency
People with a genetic condition called G6PD deficiency are at higher risk of developing rare, but serious blood problems while taking probenecid. These problems include low white blood cell counts and low red blood cell counts (anemia). A symptom of having low white blood cells is getting sick more often. Symptoms of anemia include feeling tired, weak, or dizzy, or having pale skin. If you have G6PD deficiency or experience these symptoms, talk to your provider to see whether there's another medication for gout that's right for you.
