Despite rigorous testing, some drugs have side effects that only rear their ugly heads when introduced to the general population. Forbes catalogs some of the weirdest:
- Anti-smoking drug Chantix can cause insomnia and nightmares.
- Diet drug Alli can have unforeseen gastrointestinal side-effects; these can be counteracted by eating a low-fat diet, of all things.
- Mirapex, prescribed for Parkinson's and restless-leg-syndrome patients, can lead to compulsive-eating and gambling urges.
