Lyrica has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.

In these studies, some of the most common Lyrica side effects included:

Dizziness -- in up to 45% of people
Drowsiness -- up to 28%
Coordination problems -- up to 20%
Weight gain -- up to 16%
Dry mouth -- up to 15%
Infections -- up to 14%
Headaches -- up to 14%
Accidental injury -- up to 11%
Shakiness (tremors) -- up to 11%.

Some other common side effects of Lyrica, occurring in 1% to 10% of people, included:

Memory loss, problems concentrating, or slow thinking; Constipation; Speech problems; Weakness; Increased appetite; Problems walking; Twitching; A spinning sensation (vertigo); Chest pain; Gas; Unexplained pleasant or happy feelings (euphoria); Vomiting; Back pain; Bladder control problems; Flu-like symptoms (such as body aches and chills); Low blood sugar (hypoglycemia); Nervousness; Fatigue; Feeling abnormal or drunk; Sinus infections; Joint pain; Muscle spasms.

Some side effects of Lyrica are potentially serious and should be reported immediately to the doc. These include, but are not limited to:

Signs of congestive heart failure, including difficulty breathing and water retention or swelling (especially in the hands, legs, or feet); Unusual bruising or bleeding; An irregular heart rhythm (arrhythmia); Any vision changes, including blurred vision or double vision; A need to take more Lyrica than prescribed, especially if you think you may be dependent or addicted to Lyrica; Unexplained muscle pain or weakness, especially if accompanied by a fever and fatigue; Anxiety or confusion; Signs of an allergic reaction, including unexplained rash, hives, itching, and unexplained swelling; Suicidal thinking or behavior.

Rare Lyrica Side Effects
Rare side effects are also possible. These side effects occurred in less than 1% of people taking Lyrica during clinical trials. Because these side effects are so uncommon, it can be difficult to tell whether they are actually caused by Lyrica or by factors unrelated to the medication.

These less common side effects include, but are not limited to: Sensitivity to the sun; A stiff neck; Hangovers; Canker sores; Anemia; Hiccups; Hair loss; Dry skin; Dry eyes; Taste changes; Kidney stones; Menstrual problems.
