When you read the side effects on a medication packet that means that someone has had those side effects. All of them. Some are common, others are less so, but there is no such thing as a drug which has 0 side effects, and every single one has some which in very rare instances are serious.
Case in point, there is an anti emetic called cyclozine which is often handed out to pregnant women for morning sickness. One of the incredibly rare side effects of cyclozine is that it can cause an increased heart rate. It’s listed as a rare effect.
I get that side effect and as such I cannot take cyclozine. And yet they hand it out to pregnant women and others with gay abandon.
I have a note on my records that I can’t take it, the fact that I have atrial fibrillation is a good reason why not, ;) but I would never say to anyone else that they shouldn’t take it because of the risks.
Equally I take some drugs whose side effects can be liver failure, scarring on the lungs, over active thyroid. Those side effects are actually slightly less rare than those of cyclozine. But I take it without a second thought, because without it I would be headed for the transplant list. So benefit outweighs the risk.
If you’ve ever had surgery then you have had a 4% risk of dying under anaesthetic.
You are at risk of dying in childbirth.
And away from the medical arena every time you get into a car you are at risk of dying in a crash.
Benefit vs risk.
