I have had a few scrapes with Drs and chemist over the years one that springs to mind....

At the time I was on 20 mg of some med I cant remember which one. I would get four ___ five mg as the chemist never had the 20 mg tabs.

I used a different chemist who filled the script and off I went on my merry way.

I took the four tablets in the evening (I think they was abilify) for two days, I was so ill hubby had to take me to the Drs. Instead of taking 20 mg I was taking 80 mg boy was I ill.

So your right ALWAYS check what the Drs script is and ALWAYS check your meds BEFORE you take them.
