Every Drug Has Side Effects. Here’s the Truth About Them.

Side effects. Adverse reactions. That folded-up piece of paper in your medication box with the tiny type nobody can read. That laundry list of horrible things in every drug commercial. This week, co-hosts Erin Stein and Dr. Gillian Goddard break down what all of it really means.

We start with the definitions: all side effects are adverse reactions, but not all adverse reactions are side effects. We explain how clinical trials sort side effects from coincidences with terms like “common,” “rare,” and “incidence not known.” We break down the actual numbers behind these categories and walk through a real medication’s side effect lists.

There is no medication without side effects, but side effects shouldn’t be your only consideration. We cover how to weigh benefits against the risks of doing nothing, when to stop a medication and call your doctor, and practical pharmacy tips: similar-sounding drug names, brand vs. generic, expiration dates, and why your medicine doesn’t belong in a steamy bathroom or your checked luggage.
