pregabalin



Generic Name: pregabalin (pre GAB a lin)

What is pregabalin?

Pregabalin is an anti-epileptic drug, also called an anticonvulsant. It works by slowing down impulses in the brain that cause seizures. Pregabalin also affects chemicals in the brain that send pain signals across the nervous system.


Pregabalin is used to control seizures and to treat fibromyalgia. It is also used to treat pain caused by nerve damage in people with diabetes (diabetic neuropathy) or herpes zoster (post-herpetic neuralgia).


Pregabalin may also be used for purposes not listed in this medication guide.

Call your doctor at once if you have any new or worsening symptoms such as: mood or behavior changes, depression, anxiety, insomnia, or if you feel agitated, hostile, restless, hyperactive (mentally or physically), or have thoughts about suicide or hurting yourself.


If you are taking pregabalin to prevent seizures, keep taking the medication even if you feel fine. Do not stop using pregabalin without first talking to your doctor, even if you feel fine.

Pregabalin Dosing Information


Usual Adult Dose for Diabetic Neuropathy:

Initial dose: 50 mg 3 times a day

The maximum recommended dose is 100 mg 3 times a day in patients with a creatinine clearance of at least 60 mL/min.

The dose may be increased to 100 mg 3 times a day within 1 week based on efficacy and tolerability.

Usual Adult Dose for Postherpetic Neuralgia:

Initial dose: 75 mg 2 times a day or 50 mg 3 times a day in patients with a creatinine clearance of at least 60 mL/min

The dose may be increased to 100 mg 3 times a day within 1 week based on efficacy and tolerability.

Maximum dose: Patients who do not experience sufficient pain relief following 2 to 4 weeks of treatment with 300 mg/day and who are able to tolerate pregabalin, may be treated with up to 300 mg 2 times a day or 200 mg 3 times a day. Due to the dose-dependent adverse effects and the higher rate of treatment discontinuation due to adverse events, dosing above 300 mg/day should be reserved only for those patients who have ongoing pain and are tolerating 300 mg daily.

Usual Adult Dose for Epilepsy:

Initial dose: 75 mg 2 times a day or 50 mg 3 times a day

Doses of 150 mg to 600 mg/day have been shown to be effective as adjunctive therapy in the treatment of partial onset seizures. The total daily dose should be divided and given either 2 or 3 times a day.

Maximum dose: Based on individual patient response and tolerability, the dose may be increased to a maximum of 600 mg/day.

The efficacy of add-on pregabalin in patients taking gabapentin has not been evaluated in controlled trials. Therefore, dosing recommendations for the use of pregabalin with gabapentin cannot be offered.

Usual Adult Dose for Fibromyalgia:

Initial dose: 75 mg two times a day (150 mg/day)
The dose may be increased to 150 mg two times a day (300 mg/day) within one week based on efficacy and tolerability.

Patients who do not experience sufficient benefit with 300 mg/day may be further increased to 225 mg two times a day (450 mg/day).

Recommended dose: 300 to 450 mg/day

Although pregabalin was also studied at 600 mg/day, there is no evidence that this dose confers additional benefit and this dose was less well tolerated. In view of the dose-dependent adverse reactions, treatment with doses above 450 mg/day is not recommended.


What other drugs will affect pregabalin?


Cold or allergy medicine, sedatives, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for depression or anxiety can add to dizziness or sleepiness caused by pregabalin. Tell your doctor if you regularly use any of these medicines, or any other seizure medication.

Tell your doctor about all other medicines you use, especially:



  • rosiglitazone (Avandia, Avandamet, Avandaryl); or




  • heart or blood pressure medication such as benazepril (Lotensin), enalapril (Vasotec), lisinopril (Prinivil, Zestril), quinapril (Accupril), ramipril (Altace), and others.



This list is not complete and other drugs may interact with pregabalin. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
