Are my problems a side effect of medications I'm taking?

I have no choice of medication other than these 2.

I was on a lot of medication at the time.

For the next several days, she'll be taking a lot of medication and not feeling well.

The name of the medication didn't mean anything to her.

You should go through all of your medications once a year.

You can be on both of these medications at the same time.

A person would be on one of these medications, but not both at the same time.

Three of the five medications were new, on the market for less than two years.

All of the medications helped a little, but not enough.
