Hello, Pregabalin can cause side effects like unsteadiness, memory loss, lack of coordination etc. The alternative is non-opioid analgesics like Acetaminophen and topical analgesics like Lidocaine patch, at a dose of 1.8 % or 5 %-applied over the sites of pain for up to 12 consecutive hours per day.  Capsaicin 8% patch -up to 4 patches are applied once for 30-60 minutes. Over the counter preparations (Index)of menthol, methyl salicylate though weaker have an effect on pain. Anti-depressants like Duloxetine, Amitriptyline have also been used for chronic pain and benefits are outweighed by side effects in most patients. Other anti-epileptic Chat Doctor.
