The most common side effects were: dizziness, sleepiness, blurred vision, dry mouth, swelling of the extremities, weight gain, trouble concentrating, lack of energy, muscle weakness, constipation, and forgetfulness.
A small number of patients taking a drug of this type may experience thoughts of suicide. The doctor should be informed immediately if this occurs.
When starting the intake of pms-PREGABALIN, sleepiness or dizziness may be experienced.

When pms-PREGABALIN is taken with other medications that may cause constipation (such as opioid pain medications), it is possible that gastrointestinal problems may occur (eg., constipation, blocked or paralysed bowel). (See table.)
