Nexpam Calcium Carbonate Tablet (Precipitated Calcium Carbonate)

Adult dose

1. For gastric and duodenal ulcers, gastritis, and excessive gastric acid: Administer calcium carbonate at 1-5g orally, divided into 3-4 doses per day. 2. For calcium supplementation: Administer 1.5-3g orally, divided into 1-2 doses per day. Adjust as appropriate based on age and symptoms.

This drug should not exceed 7.5 grams per day. Patients with severe hypercalcemia or hypercalciuria, patients with hyperparathyroidism or hypothyroidism, patients with severe renal failure, and patients with achlorhydria should not use this medication. Also, as it contains lactose, patients with lactose intolerance or certain genetic metabolic disorders should not take this drug. Patients with poor kidney function or problems with heart or lung function, constipated individuals, and those taking other medications should use this drug carefully. Gastrointestinal symptoms such as nausea, constipation, or diarrhea may occur during use, and, rarely, excessive gastric acid secretion may happen. Taking high doses can lead to elevated blood calcium levels or alkaline blood symptoms. Long-term or excessive use may increase the risk of kidney stones or urinary stones. Hypersensitivity reactions, such as itching, may also occur, so caution is advised. Be sure to adhere to the prescribed dosage, and when administering to children, it should be done under the supervision of a guardian. If symptoms do not improve after taking it for more than two weeks, discontinue use and consult a doctor or pharmacist. This medication can interfere with the absorption of tetracycline antibiotics, so it is advisable not to take them together. Additionally, this medication may alter the gastrointestinal environment, affecting the absorption or excretion of other drugs, so caution is advised. Taking it frequently with milk may lead to milk-alkali syndrome such as hypercalcemia, so watch for symptoms and discontinue use if abnormalities occur. Caution is necessary when taken with vitamin D or diuretics as it may increase blood calcium levels.
