Side effect of Pregabalin

Pregabalin is used to relieve neuropathic pain (pain from damaged nerves) that can occur in your arms, hands, fingers, legs, feet, or toes if you have diabetes or in the area of your rash if you have had shingles (a painful rash that occurs after infection with herpes zoster). It is also used to treat fibromyalgia (a long-lasting condition that may cause pain, muscle stiffness and tenderness, tiredness, and difficulty falling asleep or staying asleep). Pregabalin is used with other medications to treat certain types of seizures in people with epilepsy. Pregabalin is in a class of medications called anticonvulsants. It works by decreasing the number of pain signals that are sent out by damaged nerves in the body.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. These usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.


Adverse drug reactions associated with the use of pregabalin include:

Very common (>10% of patients): dizziness, drowsiness.

Common (1–10% of patients): blurred vision, diplopia, increased appetite and subsequent weight gain, euphoria, confusion, vivid dreams, changes in libido (increase or decrease), irritability, ataxia, attention changes, abnormal coordination, memory impairment, tremors, dysarthria, parasthesia, vertigo, dry mouth and constipation, vomiting and flatulence, erectile dysfunction, fatigue, peripheral edema, drunkenness, abnormal walking, asthenia, nasopharyngitis, increased creatine kinase level.

Infrequent (0.1–1% of patients): depression, lethargy, agitation, anorgasmia, hallucinations, myoclonus, hypoaesthesia, hyperaesthesia, tachycardia, excessive salivation, sweating, flushing, rash, muscle cramp, myalgia, arthralgia, urinary incontinence, dysuria, thrombocytopenia, kidney calculus.

Rare (<0.1% of patients): neutropenia, first degree heart block, hypotension, hypertension, pancreatitis, dysphagia, oliguria, rhabdomyolysis, suicidal thoughts or behavior.


Pregabalin may also cause withdrawal effects after long-term use if discontinued abruptly. When prescribed for seizures, quitting “cold turkey” can increase the strength of the seizures and possibly cause the seizures to reoccur. Withdrawal symptoms include restlessness, insomnia, and anxiety. Pregabalin should be reduced gradually when finishing treatment. Because of complication risk associated with certain common side effects in patients affected by other health issues, Pregabalin should not be used without regular medical supervision and any side effect should immediately be reported.
