Qnerve Sr Tablet belongs to the class of medications ‘anticonvulsants’ used in the treatment of neuropathic pain. Neuropathic pain is a chronic (long-term) progressive nerve disease that causes nerve pain due to nerve damage or the nervous system's malfunctioning. It is mostly seen in patients who had suffered a trauma or nerve injury, diabetes, vitamin deficiencies, cancer, multiple sclerosis (disease of the brain and spinal cord), shingles (a viral infection), and HIV.

Qnerve Sr Tablet is a combination of two medicines: Pregabalin and Methylcobalamin. Pregabalin acts by decreasing the pain signals sent by a damaged nerve in the body. On the other hand, Methylcobalamin helps rejuvenate and protect damaged nerve cells by producing a substance called myelin (outer protective layer of nerve cell - neuron).

You should take this medicine as prescribed by your doctor. The common side-effects of Qnerve Sr Tablet are dizziness, drowsiness, headache, anorexia (loss of appetite), nausea or vomiting, diarrhea, headache, hot sensation (burning pain), vision problems, and diaphoresis (sweating). Inform your doctor if any of these side effects persist.

Qnerve Sr Tablet is a combination of two drugs: Pregabalin and Methylcobalamin. Pregabalin is an anticonvulsant that affects the brain's chemicals that send pain signals across the nervous system. It works by binding to the specific site on voltage-gated calcium channels (responsible for excitatory response), thereby decreasing brain activity. This effect helps in relieving nerve pain and lowers the risk of seizures. On the other hand, Methylcobalamin is a form of vitamin B12 that helps rejuvenate and protect damaged nerve cells by producing a substance called myelin (outer protective layer of nerve cells). Together, Qnerve Sr Tablet helps in providing relief from neuropathic pain and improved nerve signal conduction.
