Lumigan with antibiotics: interactions and safety

Antibiotic courses are common, short-term and often combined with chronic medications such as Lumigan (Bimatoprost). Most antibiotics do not interfere meaningfully with Bimatoprost at 0.01%, 0.03%, 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 Eye Care and Ophthalmic Treatments agents. Rifampicin has the opposite effect, accelerating metabolism. Most penicillins, cephalosporins, fluoroquinolones and tetracyclines have no clinically meaningful interaction with Bimatoprost at 0.01%, 0.03%.

Practical guidance

According to the prescribing information for Bimatoprost, an antibiotic course should be reviewed by the prescriber or pharmacist for known interactions before Lumigan is co-administered. Adjusted 0.01%, 0.03% dosing or temporary substitution is sometimes preferred for the duration of the antibiotic course.

Frequently asked questions

Can I take Lumigan during an antibiotic course? ▾

For most common antibiotics, yes. A few classes — notably macrolides and azole antifungals — alter how Bimatoprost is metabolised and may need a temporary 0.01%, 0.03% adjustment. The prescribing pharmacist should review any new antibiotic against the existing Lumigan regimen.

Will antibiotics make Lumigan stop working? ▾

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