Therapeutic Class: Antigout
Uses For This Medicine
Probenecid and colchicine combination is used to treat gout or gouty arthritis.
The probenecid in probenecid and colchicine helps to prevent gout attacks by removing extra uric acid from the body. The colchicine in probenecid and colchicine also helps to prevent gout attacks. Although colchicine may also be used to relieve an attack of gout, this requires more colchicine than this combination medicine contains. Probenecid and colchicine combination does not cure gout. Probenecid and colchicine will help prevent gout attacks only as long as you continue to take it.
Probenecid and colchicine combination is available only with your doctor's prescription.

Proper Use of This Medicine
If probenecid and colchicine upsets your stomach, it may be taken with food. If this does not work, an antacid may be taken. If stomach upset (nausea, vomiting, loss of appetite, or stomach pain) continues, check with your doctor.
Take probenecid and colchicine only as directed by your doctor. Do not take more of it and do not take it more often than your doctor ordered. The colchicine in this combination medicine may cause serious side effects if too much is taken.
After you begin to take probenecid and colchicine, gout attacks may continue to occur for a while. However, if you take probenecid and colchicine regularly as directed by your doctor, the attacks will gradually become less frequent and less painful than before. After you have been taking probenecid and colchicine for several months, they may stop completely.
Probenecid and colchicine 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 probenecid and colchicine also.
When you first begin taking probenecid and colchicine, 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.
The dose of probenecid and colchicine will be different for different patients. Follow your doctor's orders or the directions on the label.
