Precautions

This medication should not be used in patients with severely impaired kidney function, as excessive levels of magnesium can pose a risk in cases of poor kidney function. Furthermore, it should also be avoided in patients with diarrhea, as severe diarrhea may worsen the symptoms. Caution should be exercised when using this medication in patients with weak heart function or those with already elevated magnesium levels due to a risk of side effects. Taking this medication can occasionally cause diarrhea, as it may affect the gastrointestinal tract. Long-term or high-dose use can lead to hypermagnesemia, so the condition should be monitored closely. If hypermagnesemia is suspected, treatment can be administered via potassium salt injection; therefore, immediate consultation with healthcare providers is necessary if symptoms appear. This medication may interfere with the absorption of certain antibiotics, so it is advisable not to take them concurrently. Additionally, when taken with other medications, caution is needed as it may affect the absorption or excretion of those drugs. Taking it with a large amount of milk or calcium-containing medications may lead to milk-alkali syndrome, so symptoms should be monitored closely, and if any issues arise, the medication should be discontinued. This medication should be stored out of reach of children, and it’s best kept in a cool, dry place away from direct sunlight. Moreover, to maintain the quality of the medication and prevent misuse, it should not be transferred to other containers.
