3 yrs ago, I went to see a dermatologist with a skin condition called Dermertographism and he prescribed Hydroxyzine, which I was to take 4 times a day for years until my condition improved. I took the prescription to CVS and received Hydralazine which is medication for Hypertension. I took this medication for 2 years but became suspicious when my condition did not improve. I later discovered that CVS gave me the wrong medication which I had been refilling for 2 years. I am fairly young and now I get anxiety attacks as well as continuous, periodic, migraines. I received an apology from CVS and chose to ignore my problem hoping it will eventually go away but it has continued to persist. My PCP advised me to rest and exercise more but this is yet to solve anything. I went to the emergency room previously and they prescribed ativan, an anti-anxiety drug, but I discontinued taking it, as it is addictive. Can I file a Law Suit and receive compensation ? I have records of all prescriptions and transactions.
