Medications are always a double edged sword!
... ...The worst reaction for me was Augmentin. I vomited for 4 hours straight. Could not lay down or move, it just caused another run to the bathroom.
Augmentin is a combination drug of penicillin and something else added. I’m fine with penicillin, it’s the added thing that caused the reaction.
The old adage is still true: Show me a drug without side effects and I'll show you a drug without therapeutic effect. Risk vs benefit is still the governing rule when it comes to medications. It's unfortunate that some people have life-threatening side effects but thank goodness we have medications to control most of our maladies these days. YMMV
