MSF Essential Drugs 2024 (aluminium hydroxide/magnesium hydroxide oral monograph, page 31): "Adult: 1 to 2 tablets 3 times daily 20 minutes to one hour after meals, or 1 tablet during painful attacks", of the "400 mg aluminium hydroxide/400 mg magnesium hydroxide chewable tablet"
The first step for reflux in pregnancy, and the one to try before an acid suppressant. The GORD article's indication is that antacids are taken as and when they are needed, for the symptoms of dyspepsia or reflux, heartburn among them. The amount and the pregnancy position come from MSF Essential Drugs 2024, which records this tablet as carrying no contra-indication in pregnancy and none in breast-feeding - a plainer statement than the formulary manages for the H2 blocker that follows it.
- MSF Essential Drugs 2024 is explicit on both counts: there is no contra-indication in pregnancy, and none during breast-feeding.
- CHEW THE TABLETS - the monograph's own administration instruction.
- IT BLOCKS THE ABSORPTION OF OTHER DRUGS, and this is the caution that matters most in practice. Plenty of medicines are taken up less well from the gut while it is on board, and these must NOT go down at the same time as it: iron salts and levothyroxine, digoxin, doxycycline, gabapentin, itraconazole, chloroquine and atazanavir - leave at least 2 hours between them. Iron and levothyroxine are the two a pregnant woman is most likely to be taking already.
- Separate the quinolones and the antivirals further still. Ciprofloxacin goes either 2 hours before the antacid or 4 hours after it; dolutegravir needs 2 hours ahead of it, or 6 hours after; velpatasvir wants 4 hours' clearance either way.
- Egyptian antacid products are commonly aluminium + magnesium WITH simeticone, and several substitute magnesium oxide, trisilicate or carbonate for the hydroxide. The dose above is the one the monograph states for the 400/400 mg tablet; a different salt or a suspension is a different presentation and its own label governs.
- The monograph gives no antenatal-specific dose and states none for children under 5; over 5 it says the drug is seldom called for.
