Which drugs are commonly advised to be taken with meals to reduce gastric irritation?

• A. Potassium and aspirin
• B. Vitamin C and calcium
• C. Antibiotics only with meals
• D. Insulin and steroids

Answer: (A)

Taking certain medicines with meals helps protect the stomach lining by buffering acid and slowing contact with the gastric mucosa. This tactic is commonly recommended for drugs that can irritate the stomach.

Potassium supplements often irritate the stomach, so taking them with meals reduces this direct irritation and makes them gentler on the GI tract. Aspirin, a familiar irritant to the stomach lining because it inhibits protective prostaglandins, is also commonly advised to be taken with food to lessen gastric upset and reduce the risk of irritation or minor bleeding. The meal acts as a buffer, diluting the drug and decreasing the peak exposure of the stomach lining to the medication.

Other options don’t fit this specific safety practice as clearly. Vitamin C and calcium aren’t routinely emphasized as a pair for reducing gastric irritation, and while some antibiotics are taken with meals to lessen GI upset, the wording here about “only with meals” isn’t a general rule. Insulin and steroids aren’t a standard pairing tied to reducing gastric irritation in everyday practice, even though steroids can affect the GI tract, their primary safety guidance isn’t about taking them with meals to prevent irritation in the same way as aspirin or potassium.
