Generic Combination Risks: What You Need to Know About Drug Interactions

When you take generic combination risks, the hidden dangers that arise when multiple medications interact, even if they’re sold as over-the-counter or generic versions.

A person on opioids for back pain grabs an over-the-counter anti-nausea pill, not knowing it could cause dangerous breathing changes. Or someone managing fibromyalgia adds melatonin to trazodone, thinking it’s harmless, but the combo knocks them out too hard. These aren’t rare cases.
