What Pregabalin Pfizer is and what it is used for

Pregabalin Pfizer belongs to a group of drugs that are used i.a. to treat epilepsy, neuropathic pain, and generalized anxiety disorder in adults.

Peripheral and central neuropathic pain: Pregabalin Pfizer is used to treating long-term pain caused by a nerve injury. Several diseases can cause peripheral neuropathic pain, such as diabetes or shingles. The feeling of pain can be described as hot, burning, throbbing, radiating, stabbing, cutting, cramping, aching, stinging, numbness, and ant crawling. Peripheral and central neuropathic pain can also be associated with mood swings, sleep disorders, and fatigue (fatigue), and can have an impact on physical and social functioning as well as the overall quality of life.

Epilepsy: Pregabalin Pfizer is used to treating a particular form of epilepsy ( partial epilepsy with or without secondary generalization) in adults. Your doctor will prescribe Pregabalin Pfizer to you to treat your epilepsy as your current treatment does not keep the disease under control. You should take Pregabalin Pfizer as a supplement to your current treatment. Pregabalin Pfizer is not for use alone but should always be taken in combination with other antiepileptic medicines.

Generalized Anxiety Disorder: Pregabalin Pfizer is used to treat generalized anxiety disorder. The symptoms of generalized anxiety disorder are prolonged excessive anxiety and worry that are difficult to control. Generalized anxiety disorder can also cause restlessness or a feeling of being bloated or tense, that you easily get tired, have concentration problems or episodes of absence, feel irritable, get muscle tension or sleep disturbance. This differs from stress and strain in everyday life.
