| name | Magnesium Hydroxide |
| Classification | Antacid, laxative |
| Pharmacokinetics | Magnesium hydroxide is largely poorly absorbed in the gastrointestinal tract. It is primarily excreted as magnesium and hydroxide ions in the feces. The extent of absorption may vary based on individual factors such as intestinal motility and co-administered medications. The magnesium portion is generally well-tolerated. The hydroxide portion neutralizes stomach acid. |
| suggested dosage | | adult | | general | Dosage varies significantly depending on the specific indication (e.g., antacid vs. laxative). Consult with a healthcare professional for personalized recommendations. Dosage for antacid use is typically measured in grams, while laxative use might be expressed in terms of 'grams per dose'. | | example antacid | For mild heartburn, 1-2 teaspoons (4-8 mL) of magnesium hydroxide mixture up to 4 times daily | | example laxative | For occasional constipation, 10-30 mL of magnesium hydroxide suspension can be taken once daily |
| | important note | Do not exceed recommended dosage without consulting a doctor. Overdosage can lead to serious side effects. |

| contraindications | | 1 | Known hypersensitivity or allergy to magnesium or other components of the medication | | 2 | Severe kidney disease | | 3 | History of intestinal obstruction | | 4 | Certain types of dehydration |
|
| interactions | | 1 | Other antacids (may decrease effectiveness or cause unwanted side effects) | | 2 | Certain medications that may reduce absorption of magnesium (check with pharmacist) | | 3 | Loop diuretics (may increase risk of magnesium loss) |
|
