This medication is used to prevent kidney stones in people with a certain inherited disorder (cystinuria). Cystinuria occurs when there is too much of a certain natural substance (the amino acid cystine) in the urine, leading to formation of kidney stones. Tiopronin works by making cystine more dissolvable in the urine.
This medication should be used in combination with other methods to prevent kidney stones (such as drinking plenty of water, taking alkali treatment, following a special diet).
Take this medication by mouth 1 hour before or 2 hours after meals as directed by your doctor, usually 3 times daily.
Continue to drink plenty of water and to take the alkali medication as directed by your doctor. Closely follow the diet recommended by your doctor.
The dosage is based on your medical condition, lab tests, and response to treatment. Children's dosage may be based on weight.
