Pepcid vs. Mylanta Maximum Strength

Famotidine (Pepcid AC) and aluminum hydroxide/magnesium hydroxide/simethicone (Mylanta Maximum Strength) are both used to treat heartburn, but they work differently and have different uses. Famotidine is a histamine-2 (H2) antagonist that reduces stomach acid production and is available both over-the-counter and by prescription. It can treat conditions like stomach ulcers and GERD. On the other hand, Mylanta Maximum Strength is a combination of two antacids and a gas relief medication, which neutralizes stomach acid and helps with gas symptoms. Mylanta works quickly, within minutes, but its effects last only about an hour, whereas famotidine takes about an hour to start working but lasts several hours. Famotidine is generally well-tolerated but can cause headaches and dizziness, while Mylanta can cause diarrhea due to its magnesium content. It's best to speak with a healthcare professional before using either medication during pregnancy. Both medications are available in generic forms and can be purchased over-the-counter.
