aluminium hydroxide, dried + magnesium hydroxide interactions
Antacids can alter the absorption or elimination of other medicines. A pharmacist should check the full medicine list and advise on separation or alternatives.
Tetracycline antibiotics
The antacid can reduce antibiotic absorption, so they should not be taken together.
