Although the clinical significance of the ophthalmologic findings is unknown, inform patients to notify their physician if changes in vision occur. Consider more frequent assessment for patients who are already routinely monitored for ocular conditions see Patient Counseling Information (17). Inform patients that LYRICA-related dizziness and somnolence may impair their ability to perform tasks such as driving or operating machinery see Patient Counseling Information (17).
Small amounts of pregabalin have been detected in the milk of lactating women. A pharmacokinetic study in lactating women detected pregabalin in breast milk at average steady state concentrations approximately 76% of those in maternal plasma. The estimated average daily infant dose of pregabalin from breast milk (assuming mean milk consumption of 150 mL/kg/day) was 0.31 mg/kg/day, which on a mg/kg basis would be approximately 7% of the maternal dose see Data. The study did not evaluate the effects of LYRICA on milk production or the effects of LYRICA on the breastfed infant. In view of dose-dependent adverse reactions and since LYRICA is eliminated primarily by renal excretion, adjust the dose in adult patients with reduced renal function. The use of LYRICA in pediatric patients with compromised renal function has not been studied.
- There are postmarketing reports of life-threatening or fatal respiratory depression in patients taking LYRICA with opioids or other CNS depressants, or in the setting of underlying respiratory impairment.
- As this is one of the most convenient forms, this is also one of the most common dosage forms used.
- Find information about finished drug products, unfinished drugs, and compounded drug products.
- Patients taking gabapentin were required to discontinue gabapentin treatment 1 week prior to entering baseline.
Other Medical Problems
Pregabalin, at concentrations that were, in general, 10-times those attained in clinical trials, does not inhibit human CYP1A2, CYP2A6, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4 enzyme systems. In vitro drug interaction studies demonstrate that pregabalin does not induce CYP1A2 or CYP3A4 activity. Therefore, an increase in the metabolism of coadministered CYP1A2 substrates (e.g. theophylline, caffeine) or CYP 3A4 substrates (e.g., midazolam, testosterone) is not anticipated. In the postmarketing experience, the most commonly reported adverse events observed with pregabalin when taken in overdose include reduced consciousness, depression/anxiety, confusional state, agitation, and restlessness.

Table 9 lists all adverse reactions, regardless of causality, occurring in greater than or equal to 2% of patients with fibromyalgia in the ‘all pregabalin’ treatment group for which the incidence was greater than in the placebo treatment group. A majority of pregabalin-treated patients in clinical studies experienced adverse reactions with a maximum intensity of “mild” or “moderate”. The efficacy of LYRICA as adjunctive therapy for partial-onset seizures in adult patients was established in three 12-week, randomized, double-blind, placebo-controlled, multicenter studies. Patients were enrolled who had partial-onset seizures with or without secondary generalization and were not adequately controlled with 1 to 3 concomitant antiepileptic drugs (AEDs). Patients taking gabapentin were required to discontinue gabapentin treatment 1 week prior to entering baseline. During an 8-week baseline period, patients had to experience at least 6 partial-onset seizures with no seizure-free period exceeding 4 weeks.

In the pregabalin treatment group, the most common reasons for discontinuation due to adverse reactions were dizziness (6%) and somnolence (3%). In comparison, less than 1% of placebo-treated patients withdrew due to dizziness and somnolence. Other reasons for discontinuation from the trials, occurring with greater frequency in the pregabalin treatment group than in the placebo treatment group, were fatigue, headache, balance disorder, and weight increased. Each of these adverse reactions led to withdrawal in approximately 1% of buy pregabalin 300 mg patients.
