When should antacids be avoided to ensure proper medication absorption?

Antacids are designed to neutralize stomach acid and relieve symptoms of indigestion and heartburn. However, when taken with meals, they can interfere with the absorption of certain medications by altering the pH of the stomach. Many medications require an acidic environment for optimal absorption, and if an antacid is consumed simultaneously with food, it can change the way the body absorbs those medications, potentially reducing their effectiveness.

Avoiding antacids during meals helps ensure that the medications taken around that time can be fully absorbed as intended. This timing is crucial, especially for medications such as certain antifungals, some antibiotics, and medications for chronic conditions that rely on proper absorption for therapeutic effect.
