Description
Pregabalin is used with other medicines to help control partial-onset seizures (convulsions) in the treatment of epilepsy in patients 1 month of age and older. This medicine will not cure epilepsy and will only work to control seizures for as long as you continue to take it.
Pregabalin is also used for postherpetic neuralgia (pain that occurs after shingles) and pain caused by nerve damage from diabetes or a spinal cord injury.
Pregabalin capsule and oral liquid are also used to treat a condition called fibromyalgia (muscle pain and stiffness).
Pregabalin works in the central nervous system (CNS) to control seizures and pain. It is an anticonvulsant and neuropathic pain agent.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:
- Capsule
- Tablet, Extended Release
- Solution
Before Using
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies have not been performed on the relationship of age to the effects of pregabalin capsules and oral liquid in children younger than 1 month of age for partial onset seizures and extended-release tablets in children. Safety and efficacy have not been established for other conditions.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of pregabalin in the elderly. However, elderly patients are more likely to have unwanted effects (eg, dizziness, blurred vision, confusion, or clumsiness) and age-related kidney problems, which may require an adjustment in the dose for patients receiving pregabalin.

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Check with your doctor before using this medicine with alcohol or other medicines that affect the central nervous system (CNS). The use of alcohol or other medicines that affect the CNS with pregabalin may worsen the side effects of this medicine, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.
This medicine may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts or to become more depressed. Also tell your doctor if you have sudden or strong feelings, including feeling nervous, angry, restless, violent, or scared. If you or your caregiver notice any of these side effects, tell your doctor right away.
This medicine may cause respiratory depression, a serious breathing problem that can be life-threatening, when used together with narcotic pain medicines. Check with your doctor right away if you have pale or blue lips, fingernails, or skin, difficulty or trouble breathing, or irregular, fast or slow, or shallow breathing.
Pregabalin may cause blurred vision, double vision, clumsiness, unsteadiness, dizziness, drowsiness, or trouble with thinking.
