If probenecid upsets your stomach, it may be taken with food. If this does not work, an antacid may be taken. If stomach upset (nausea, vomiting, or loss of appetite) continues, check with your doctor.
For patients taking probenecid for gout:
- After you begin to take probenecid, gout attacks may continue to occur for a while. However, if you take this medicine regularly as directed by your doctor, the attacks will gradually become less frequent and less painful than before. After you have been taking probenecid for several months, they may stop completely.
- This medicine will help prevent gout attacks but it will not relieve an attack that has already started. Even if you take another medicine for gout attacks, continue to take this medicine also. If you have any questions about this, check with your doctor.
For patients taking probenecid for gout or to help remove uric acid from the body:
- When you first begin taking probenecid, the amount of uric acid in the kidneys is greatly increased. This may cause kidney stones or other kidney problems in some people. To help prevent this, your doctor may want you to drink at least 10 to 12 full glasses (8 ounces each) of fluids each day, or to take another medicine to make your urine less acid. It is important that you follow your doctor's instructions very carefully.

- For treating gout or removing uric acid from the body:
- Adults: 250 mg (one-half of a 500-mg tablet) two times a day for about one week, then 500 mg (one tablet) two times a day for a few weeks. After this, the dose will depend on the amount of uric acid in your blood or urine. Most people need 2, 3, or 4 tablets a day, but some people may need higher doses.
- Children: It is not likely that probenecid will be needed to treat gout or to remove uric acid from the body in children. If a child needs this medicine, however, the dose would have to be determined by the doctor.
- For helping antibiotics work better:
- Adults: The amount of probenecid will depend on the condition being treated. Sometimes, only one dose of 2 tablets is needed. Other times, the dose will be 1 tablet four times a day.
- Children: The dose will have to be determined by the doctor. It depends on the child's weight, as well as on the condition being treated. Older children and teenagers may need the same amount as adults.
