Nexium vs. Mylanta Maximum Strength

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Esomeprazole (Nexium) and Mylanta Maximum Strength (aluminum hydroxide / magnesium hydroxide / simethicone) are both used to treat heartburn and acid reflux, but they work in different ways. Esomeprazole is a proton pump inhibitor (PPI) that reduces stomach acid production and is available both over-the-counter and by prescription. It takes a few days to feel its full effects and sometimes requires longer-term treatment for certain conditions. On the other hand, Mylanta Maximum Strength is a combination of two antacids and a gas relief medication that neutralizes stomach acid and works within minutes, providing quick but short-term relief. Mylanta is available over-the-counter and is not recommended for use during pregnancy, while it's not known if it's safe to use esomeprazole during pregnancy. Esomeprazole has potential long-term side effects like bone weakening and low magnesium levels, whereas Mylanta can cause diarrhea and may not be suitable for people with kidney problems. Both medications have generic forms available, making them more affordable options.

Summary for Nexium

Prescription or over-the-counter

Esomeprazole (Nexium) is a medication used to treat conditions that are caused by too much stomach acid, such as heartburn or acid reflux. It's available both with a prescription and over the counter (OTC). Take esomeprazole (Nexium) an hour before a meal so that it can start working before you eat. It can take a couple days for you to feel its full effects, so consider taking other quick-acting antacids in the meantime until the medication effect kicks in.
