This medicine should not be used by those allergic to it or any of its components. It should not be administered to patients with hyperoxaluria who excrete excessive oxalates, patients with thalassemia, gout patients, or patients with cystinuria. Additionally, patients with G6PD deficiency should be cautious as excessive use may lead to hemolysis. Patients with oxalate kidney stones should not exceed 1 gram per day. Side effects may include nausea, vomiting, diarrhea, heartburn, abdominal cramps, fatigue, flushing, headache, insomnia, and may occur with overdosing. Administering more than 1 gram per day may acidify urine and increase the risk of diarrhea and kidney stones. Doses exceeding 600 milligrams may lead to diuresis. Overdose may result in the deposition of urates or oxalates in the urinary tract, causing stones. This medicine is usually taken orally but should be administered by injection if gastrointestinal absorption is difficult or in emergencies, switching to oral administration as soon as possible is recommended. The effectiveness may change when used with certain medications, so avoid concurrent use with aspirin, smoking, alcohol, iron supplements, and certain antibiotics.

This drug passes into breast milk, but the standard dosage is not harmful to infants. Notify the doctor before any laboratory tests as this medication may influence some urine or blood test results. Overdosing may lead to diarrhea or kidney stones, and if symptoms arise, stop taking it immediately and seek treatment. Injection may cause temporary pain at the injection site, and special caution should be taken with newborns and children. If there is pain or blood reflux during injection, the injection should be stopped immediately. Rapid intravenous injection may cause fainting or dizziness, so slow infusion is necessary.
