Uses for Probalan

Probenecid is used to treat chronic gout or gouty arthritis. These conditions happen because there is too much uric acid in the blood. The medicine works by getting rid of the extra uric acid from the body. Probenecid does not cure gout, but after you have been taking it for a few months, it will help prevent gout attacks. This medicine will help prevent gout attacks only as long as you keep taking it.

Probenecid is also used to prevent or treat other health issues that may happen if there is too much uric acid in the body.

Probenecid is sometimes used with certain types of antibiotics to make them work better in treating infections.

Probenecid is available only with your doctor's prescription.

Precautions while using Probalan

If you will be taking probenecid for more than a few weeks, your doctor should check your progress at regular visits.

Before you have any medical tests, tell the person in charge that you are taking this medicine. The results of some tests may be affected by probenecid.

For diabetic patients:

  • Probenecid may cause false test results with copper sulfate urine sugar tests (Clinitest®), but not with glucose enzymatic urine sugar tests (Clinistix®). If you have any questions about this, check with your health care professional.

For patients taking probenecid for gout or to help remove uric acid from the body:

  • Taking aspirin or other salicylates may lessen the effects of probenecid. This will depend on the dose of aspirin or other salicylate that you take, and on how often you take it. Also, drinking too much alcohol may increase the amount of uric acid in the blood and lessen the effects of this medicine. Therefore, do not take aspirin or other salicylates or drink alcoholic beverages while taking this medicine, unless you have first checked with your doctor.

Proper use of Probalan

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.

Dosing

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

  • 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.
