Is there a possibility that the doctor made a mistake in signing me Alpragen for numbness in my hands?

The probability that your doctor prescribed you an incorrect drug is very small. It should be remembered that any drug can be prescribed by a doctor off-label from the leaflet, based on his best knowledge and experience, if he considers that such a practice will be helpful and safe for the patient. This is the so-called off-label use of the drug, which we wrote about here: https://www.gdziepolek.pl/artykuly/leczenie-off-label-poza-wskazaniami If you have doubts about the legitimacy of prescribing your Alpragen drug, I encourage you to dispel them in a telephone conversation with the doctor who recommended it: https://www.gdziepolek.pl/blog/jak-telefoniczne-otrzymac-recepte-i-zwolnienie-lekarskie
