Conventional medicines: benefits, limits and adverse effects

Approval means the benefits were judged greater than the known risks. It never means there are no risks — and the topic pages say which ones.

A medicine approved for sale in the United States must be safe and effective, which the FDA defines as its benefits being greater than its known risks.1 That is a comparison, not a guarantee: both prescription and over-the-counter drugs have side effects,2 ranging from minor problems to life-threatening events such as a heart attack or liver damage.3 Side effects that do occur can be reported to the FDA's MedWatch programme.4

How ProperHealth presents this

On every topic that carries the comparison block, the conventional column states what the medicines achieve — with the trial or guideline behind it — and the next column states the limits and adverse effects from the same official sources. Statins and the small rise in diabetes risk; blood pressure medicines and dizziness on standing; sulfonylureas and low blood sugar; aspirin and bleeding risk. Benefits and harms come from the same shelf.

What this does not license

It does not license the sentence "medicines do more harm than good", and the site never says it. Nor does it license the opposite reflex. A known adverse effect is a reason to ask about the dose, the alternative or the plan — not, on its own, a reason to stop a medicine that is preventing a stroke. Every comparison block ends with that boundary.
