This medication can introduce glass fragments when opening the injection container, so care must be taken during use. Extra caution is required when being used by children or the elderly. This medication contains sodium bisulfite, which can cause serious allergic reactions or asthma attacks in individuals who are allergic to sulfites, so it should be used cautiously. Patients with asthma should be especially careful. This medication should not be used in certain patients. For example, individuals allergic to this medication or its components, patients with oxalate nephropathy or Mediterranean anemia, gout or cystinuria patients, G6PD deficiency patients, and those with renal oxalate stones should not be administered this drug. While using this medication, side effects such as nausea, vomiting, diarrhea, abdominal pain, cramps, fatigue, flushing, headache, insomnia may occur. Administering more than 1 gram per day can acidify urine, increasing the risk of diarrhea or kidney stones. Taking more than 600 milligrams a day can lead to diuretic effects, and hemolysis may occur in G6PD deficiency patients. Excessive dosage can precipitate oxalate or urate in the urinary tract, so caution is warranted. This medication is generally taken orally, but injections should only be used in acute conditions or when oral administration is challenging, and switching to oral administration is advisable when possible. This medication can interact with other drugs. Salicylates may impair the absorption of this drug, and using it with aspirin, nicotine, alcohol, some appetite suppressants, iron supplements, certain anticonvulsants, oral contraceptives, and tetracycline antibiotics may diminish its effectiveness, so concurrent use should be avoided. Additionally, high-dose administration may reduce the effects of some anticoagulants and can interact with certain psychiatric medications. During pregnancy, the effects on the fetus are unclear, so this medication should only be administered when the benefits outweigh the risks, and high doses exceeding 1 gram should be avoided. While breastfeeding, this medication can pass into breast milk, but it is known to be non-harmful to infants at typical doses. This medication may affect the results of certain clinical tests, potentially yielding false results in urine glucose tests, hematuria tests, and occult blood tests in stool. Overdosage can lead to diarrhea or kidney stones, and diuretic effects may manifest with doses exceeding 600 milligrams daily, so dosing should be stopped immediately if symptoms appear and appropriate treatment should be sought. When administered via injection, temporary pain may occur at the injection site, and injections should be administered with minimal volume, avoiding nerve regions. If pain or blood reflux is experienced when injecting, the needle should be removed immediately, and intravenous injections should be administered slowly to reduce dizziness or vascular pain. Finally, this medication should be kept out of the reach of children and stored in a dry place away from direct sunlight. Transferring the medication to another container may lead to misuse or degradation of quality, so it should always be stored in its original container with the lid tightly closed.
