what does fda look for in safe medication
No medicine can be sold unless it has first been approved by the U.S. Food and Drug Administration (FDA). The manufacturers of the medication perform tests on all new medicines and send the results to the FDA. The FDA allows new medicines to be used only if they work and if they are safe enough. When a medicine's benefits outweigh its known risks, the FDA usually approves the sale of the drug. The FDA can withdraw a medication from the market at any time if it later is found to cause harmful side effects.
