Pharmacy cause permanent nerve damage, do I have a case to peruse for damages or are they protected?

It depends if you ordered timely.

You may be entitled to file a cause of action in negligence if the pharmacy failed to perform a duty and the breach of that duty resulted in quantifiable damages.

You need to have your medical records reviewed by your doctor, or someone else of his specialty, to render an opinion as to whether the delay of obtaining your medication caused and/or contributed to your nerve damage. Also need a neurologist to opine that your nerve damage is permanent and could have been avoided had you timely taken your medication. If these facts are established by expert medical opinions, then you may have a case, especially if it can be established that the pharmacy knew, or should have known, that the timely dispensation of your medication was crucial to prevent the injury you in fact sustained. You may need an expert in the field of pharmacology. Pharmacy's have no particular immunities. I successfully sued a major pharmacy for dispensing the wrong dosage of a corticoroid (prednisone) rather than dispensing .5 mg tablets of the drug, the pharmacy dispensed 50 mg tablets! The pharmacy settled with me prior to going to trial.

Delay in filling prescription? Not very clear and does not sound like a liability case. in any event you would have to prove they they were negligent and that the negligence clearly caused whatever problem you say you have. If you have a doctor who will say that (and you must) find you a good PI lawyer and share the whole story.

You would have get a doctor to testify that was the reason you have nerve damage and you would have to prove it was the pharmacy fault your prescription was not called in a timely manner.

It sounds like the culprit is the insurance company, more so than the pharmacy, although both may be at fault. If the injuries are severe enough, it may justify pursuit.

I think you do have a case, or at least a situation that deserves some serious investigation. Two key issues: (1)What are the obligations of a pharmacy to fill a prescription in a "timely" manner and (2) Can you prove that there is nerve damage and that it is due to the tardy prescription?

I don't see a winning case. Your condition sounds advanced enough that any defendant could say your condition was destined to progress and they shouldn't be blamed for the whole problem. Why did you wait two weeks?
