Tiopronin is a tablet taken orally typically prescribed for patients who are prone to kidney stones. Specifically, this drug is used by patients who have an excessive amount of cystine in the urine (cystinuria), producing a concentration of more than 500 mg per day. This condition is typically inherited, and Tiopronin treats it by improving how cystine dissolves in the patient’s urine.
Tiopronin is usually only prescribed after other methods, such a change of diet (restricting sodium use) or increasing water or fluid intake, have proven unsuccessful in preventing kidney stones. It is also typically prescribed to patients who are unable to take other medications for cystinuria. Since the severity of cystinuria can range, the length of time this drug is prescribed to a patient can range from short-term to long term. In addition to taking the medication, a doctor may encourage the patient to continue with the aforementioned lifestyle changes in order to receive the most benefit from treatment.
Although Tiopronin is helpful for treating kidney stones, the side effects of the drugs can be very serious. It’s important to fully discuss the use of this drug with your healthcare professional.
On rare occasions, Tiopronin is sometimes also prescribed as part of a treatment for Wilson's disease. In that situation, it's used to bind metal nanoparticles when there is an oversupply of copper throughout the body. In addition, it has been researched in usage for treating arthritis, as well as treatment in the occurrence of aneurysmal subarachnoid hemorrhage.
A less common side effect is a change in the patient’s taste or smell.
These more typical side effects tend to go away as patients become used to the medication. If the aforementioned side effects tend to become bothersome or do not go away with time, it’s important to discuss your concerns with your healthcare professional. Your physician may be able to answer additional questions you have or help you reduce the appearance of these symptoms.
In addition, if you experience pain, swelling, or tenderness of the skin, a skin rash, hives, or itching, or ulcers and sores in the mouth, it’s important to consult your physician as soon as possible.

Tiopronin is a tablet taken orally prescribed to patients who are prone to kidney stones. The drug works by preventing kidney stones by reducing the amount of cystine in their urine (cystinuria). Cystinuria is typically inherited condition where a patient produces an excess of cystine, which can lead to kidney stones. Patients who take this drug typically has a daily cystine concentration of over 500 mg per day. By using Tiopronin, a patient can reduce the likelihood of kidney stones and thus the need for kidney stone treatment. Typically, Tiopronin is only prescribed after non-medical treatment, such as a change in diet, or if other medical treatments attempted are not successful. Tiopronin may also rarely be prescribed to treat Wilson’s disease, as it can help combat an oversupply of copper in the body.
While taking Tiopronin, it’s important for the patient to pay close attention to side effects. It could cause rare but very serious side effects that need to be monitored closely or treated immediately by a physician. This can include yellowing of the skin, unusual bleeding, and breathing issues. Less severe and less common side effects could appear during treatment, but may eventually dissipate as treatment continues. The patient’s physician could choose to alter treatment as time goes on, depending on whether or not the intended outcome has been accomplished.
