Thiola EC

Thiola EC is used along with diet, fluids, and other medicines to help prevent kidney stones in adults and children who weigh at least 44 pounds (20 kilograms).

Thiola EC is typically prescribed when diet, drinking more fluids, or other medications have not worked.

Thiola EC may also be used for reasons not mentioned in this medication guide.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Take the medicine at the same time each day, with or without food.

Swallow the tablet whole and do not crush, chew, or break it.

Drink plenty of liquids while you are taking Thiola EC.

You will need frequent urine tests.

Store at room temperature away from moisture and heat.

Follow all instructions on your medicine label and package. Inform each of your healthcare providers about all your medical conditions, allergies, and all medicines you are taking.

You should not use Thiola EC if you are allergic to it.

Thiola EC should not be given to a child who cannot swallow a tablet.

Tell your doctor if you are pregnant. It is not known if Thiola EC will harm an unborn baby. However, having a kidney stone during pregnancy may lead to complications such as low birth weight or premature birth. The benefit of preventing kidney stones may be greater than any risks to the baby.

You should not breastfeed while using Thiola EC.

Get emergency medical help if you have signs of an allergic reaction: hives, rash; fever, swollen glands, joint pain; difficult breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have signs of kidney problems--puffy eyes, swelling in your ankles or feet, weight gain, or urine that looks foamy.

• nausea, diarrhea, vomiting;
