These medications always take their share of nutrients from your system when they
are being digested. Look up your medications online and check all of the side effects.
Some sites will tell you which vitamins are being depleted by the use of that med.

For example, strong fatigue hits me on Prozac. The side effects of it are that it
drains the vitamin B6 from the system. So I take a daily supplement of vitamin B6
to counteract the medications use.

You may find a website that will give such helpful information; I hope so, and you
will be able to assist your system to manage the side effects of prescribed and over-the-counter medications.

Take care.
