Additional dosage information:
Usual Adult Dose for Diabetic Neuropathy
Immediate-release:
Initial dose: 50 mg orally 3 times a day
- Dose may be increased to 100 mg orally 3 times a day within 1 week based on efficacy and tolerability
Extended-release:
Initial dose: 165 mg orally once a day after the evening meal
- Dose may be increased to 330 mg orally once a day within 1 week based on efficacy and tolerability
Conversion from Immediate-release to Extended-release:
- On the day of the switch, take morning dose as prescribed and initiate extended-release therapy after the evening meal. See dose adjustment section for equivalent doses.
Comment:
- Doses of 600 mg per day have been studied and do not appear to confer additional significant benefit; treatment with doses above 300 mg per day (immediate-release) or 330 mg per day (extended-release) are not recommended due to dose-dependent adverse reactions.
Use: Management of neuropathic pain associated with diabetic peripheral neuropathy
Usual Adult Dose for Postherpetic Neuralgia
Immediate-release:
Initial dose: 150 to 300 mg orally per day in 2 or 3 divided doses
- Dose may be increased to 300 per day in 2 or 3 divided doses within 1 week based on efficacy and tolerability
- If, after 2 to 4 weeks of therapy at 300 mg per day, there is insufficient pain relief and patient is tolerating therapy, dose may be increased up to 600 mg per day in 2 or 3 divided doses
Extended-release:
Initial dose: 165 mg orally once a day after the evening meal
- Dose may be increased to 330 mg orally once a day within 1 week based on efficacy and tolerability
- If, after 2 to 4 weeks of therapy at 330 mg per day, there is insufficient pain relief and patient is tolerating therapy, dose may be increased up to 660 mg per day
Conversion from Immediate-release to Extended-release:
- On the day of the switch, take morning dose of immediate release pregabalin as prescribed and initiate extended-release therapy after the evening meal. See dose adjustment section for equivalent doses.
Comment:
- Treatment with doses above 300 mg per day (immediate-release) or 330 mg per day (extended-release) should be reserved for patients with on-going pain who have demonstrated tolerability at lower doses due to the high rate of discontinuation from adverse reactions at higher doses.

Comments:
- This drug has been studied at 600 mg per day, however, as there was no evidence of additional benefit and due to dose-dependent adverse reactions, treatment with doses above 450 mg per day is not recommended.

Is pregabalin best taken at night?
You should take pregabalin twice a day, morning and night. It is important to take your pregabalin dose regularly, as prescribed for this medicine to work properly. It is not a medication that you should use on an 'as required' basis.
Does pregabalin affect sleep?
Polysomnographic data reveal that pregabalin primarily affects sleep maintenance. The evidence indicates that pregabalin has a direct effect on sleep that is distinct from its analgesic, anxiolytic and anticonvulsant effects. Keywords: Patient-report; Polysomnography; Pregabalin; Sleep disturbance.
Why do you take pregabalin at night?
Treatment with pregabalin is associated with improvement in all forms of insomnia and improvement in sleep has been found to be correlated with reduction in functional impairment and improvement in quality of life on subjective global measures.
Can you take pregabalin during the day?
You'll usually take pregabalin 2 or 3 times a day. You can take it with or without food. Pregabalin is often used for epilepsy, but you can also take it to help with pain or anxiety if you do not have epilepsy. It takes at least a few weeks for pregabalin to work.
