wrong perscription

In order to have a valid medical malpractice case, you must be able to prove that you suffered some injury as a result of the doctor's (or in this case the pharmacy's) mistake. If I were you, I would contact a lawyer in your area who has a proven track record in medical malpractice cases. He or she will be able to determine if your hospitalization and the other effects of taking the wrong medication for 3 months will provide you with legitimate grounds for a lawsuit. It sounds like you have suffered damages as a result of this error, it's just a matter of whether it can be proven in a court of law. Best of luck.

I've heard that a lot if times in a medical malpractice case, you need to have an expert witness (usually a doctor or nurse) testify confirming that the negligence of a medical professional caused you an injury. So, basically, if a medical expert witness would agree that because you received the wrong medication it caused you some harm, you will have a much stronger case. I definitely think you still need to talk to an attorney, I just thought I'd share what I've heard about these kinds of things.

If I were you, I would probably consult a medical malpractice lawyer and see if what are legal actions to take.
