Lyrica with antibiotics: interactions and safety

Antibiotic courses are common, short-term and often combined with chronic medications such as Lyrica (Pregabalin). Most antibiotics do not interfere meaningfully with Pregabalin at 25mg, 50mg, 75mg, 100mg, 150mg, 200mg, 225mg, 300mg, but a few classes do, and a small number of combinations are best avoided.

Common antibiotic interactions

Macrolides (clarithromycin, erythromycin) and certain antifungals can inhibit hepatic metabolism (CYP3A4) and raise plasma levels of many medications including some Pain Relief Medications agents. Rifampicin has the opposite effect, accelerating metabolism. Most penicillins, cephalosporins, fluoroquinolones and tetracyclines have no clinically meaningful interaction with Pregabalin at 25mg, 50mg, 75mg, 100mg, 150mg, 200mg, 225mg, 300mg.

Practical guidance

According to the prescribing information for Pregabalin, an antibiotic course should be reviewed by the prescriber or pharmacist for known interactions before Lyrica is co-administered. Adjusted 25mg, 50mg, 75mg, 100mg, 150mg, 200mg, 225mg, 300mg dosing or temporary substitution is sometimes preferred for the duration of the antibiotic course.

Frequently asked questions

Can I take Lyrica during an antibiotic course? ▾

For most common antibiotics, yes. A few classes — notably macrolides and azole antifungals — alter how Pregabalin is metabolised and may need a temporary 25mg, 50mg, 75mg, 100mg, 150mg, 200mg, 225mg, 300mg adjustment. The prescribing pharmacist should review any new antibiotic against the existing Lyrica regimen.

Will antibiotics make Lyrica stop working? ▾

Most antibiotics do not affect Lyrica efficacy. Rifampicin and a few others can lower Pregabalin levels and reduce effect; in those cases the prescriber may adjust the dose during and shortly after the antibiotic course.
