Use Food to Improve a Drug’s Performance

By Carol Ann Rinzler

Not every food and drug interaction is an adverse one. Sometimes a drug works better or is less likely to cause side effects when you take it on a full stomach. For example, aspirin is less likely to upset your stomach if you take the painkiller with food, and eating stimulates the release of stomach juices that improve your ability to absorb griseofulvin, an antifungus drug.

The table lists some drugs that may work better when your stomach is full.

Drugs That Work Better on a Full Stomach
Purpose Drug
Analgesics (painkillers) Acetaminophen Aspirin Codeine Ibuprofen Indomethacin Mefenamic acid Metronidazole Naproxen/naproxen sodium
Antibiotics, antivirals, antifungals Ethambutol Griseofulvin Isoniazid Ketoconazole Pyrimethamine
Antidiabetic agents Glipizide Glyburide Tolazamide Tolbutamide
Cholesterol-lowering agents Cholestyramine Colestipol Lovastatin Probucol
Gastric medications Cimetidine Ranitidine
