Rhea Pregabalin Dosage/Direction for Use

The dose range is 150 to 600 mg per day given in either two or three divided doses.
Pregabalin may be taken with or without food.
Neuropathic pain: Pregabalin treatment can be started at a dose of 150 mg per day. Based on individual patient response and tolerability, the dosage may be increased to 300 mg per day after an interval of 3 to 7 days, and if needed, to a maximum dose of 600 mg per day after an additional 7-day interval.
Fibromyalgia: The usual dose range for most patients is 300 to 450 mg per day given in two divided doses. Some patients may derive additional benefit at 600 mg per day. Dosing should begin at 75 mg two times a day (150 mg/day) and may be increased to 150 mg two times a day (300 mg/day) within 1 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). If needed, in some patients, based on individual response and tolerability, the dose may be increased to maximum dosage of 600 mg/day after an additional week.
Epilepsy: Pregabalin treatment can be started with a dose of 150 mg per day. Based on individual patient response and tolerability, the dosage may be increased to 300 mg per day after 1 week. The maximum dosage of 600 mg per day may be achieved after an additional week.
Generalized Anxiety Disorder: The dose range is 150 to 600 mg per day given as two or three divided doses. The need for treatment should be reassessed regularly.
Pregabalin treatment can be started with a dose of 150 mg per day. Based on individual patient response and tolerability, the dosage may be increased to 300 mg per day after 1 week. Following an additional week the dosage may be increased to 450 mg per day. The maximum dosage of 600 mg per day may be achieved after an additional week. Discontinuation of pregabalin: If pregabalin has to be discontinued, it is recommended this should be done gradually over a minimum of 1 week.
Patients with renal impairment: Dosage reduction in patients with compromised renal function must be individualized according to creatinine clearance (CLcr) (see Section 5.2 Pharmacokinetic Properties, Pharmacokinetics in special patient groups, Renal impairment), as indicated in Table 1 determined using the following formula: CLcr (mL/min) = [140 - age (years)] x weight (kg) (x 0.85 for female patients) 72 x serum creatinine (mg/dL).
For patients receiving hemodialysis, the pregabalin daily dose should be adjusted based on renal function. In addition to the daily dose, a supplementary dose should be given immediately following every 4-hour hemodialysis treatment (see Table 1).

Use in patients with hepatic impairment: No dosage adjustment is required for patients with hepatic impairment (see Pharmacology: Pharmacokinetics under Actions).
Use in children and adolescents (12 to 17 years of age): The safety and effectiveness of pregabalin in pediatric patients below the age of 12 years and adolescents has not been established. The use in children is not recommended (see Toxicology: Preclinical Safety Data under Actions).
Use in the Elderly (over 65 years of age): Elderly patients may require a dose reduction of pregabalin due to decreased renal function (see Pharmacology: Pharmacokinetics under Actions).
