Antiviral Medications with antibiotics: interactions and safety
Antibiotic courses are common, short-term and often combined with chronic medications such as Antiviral Medications (Antiviral Medications). Most antibiotics do not interfere meaningfully with Acyclovir, Oseltamivir, Valacyclovir at 200mg, 400mg, 800mg, 30mg, 45mg, 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 Antiviral Medications agents. Rifampicin has the opposite effect, accelerating metabolism. Most penicillins, cephalosporins, fluoroquinolones and tetracyclines have no clinically meaningful interaction with Acyclovir, Oseltamivir, Valacyclovir at 200mg, 400mg, 800mg, 30mg, 45mg.
Practical guidance
According to the prescribing information for Acyclovir, Oseltamivir, Valacyclovir, an antibiotic course should be reviewed by the prescriber or pharmacist for known interactions before Antiviral Medications is co-administered. Adjusted 200mg, 400mg, 800mg, 30mg, 45mg dosing or temporary substitution is sometimes preferred for the duration of the antibiotic course.
Frequently asked questions
Can I take Antiviral Medications during an antibiotic course? ▾
For most common antibiotics, yes. A few classes — notably macrolides and azole antifungals — alter how Acyclovir, Oseltamivir, Valacyclovir is metabolised and may need a temporary 200mg, 400mg, 800mg, 30mg, 45mg adjustment. The prescribing pharmacist should review any new antibiotic against the existing Antiviral Medications regimen.
Will antibiotics make Antiviral Medications stop working? ▾
Most antibiotics do not affect Antiviral Medications efficacy. Rifampicin and a few others can lower Acyclovir, Oseltamivir, Valacyclovir levels and reduce effect; in those cases the prescriber may adjust the dose during and shortly after the antibiotic course.
