Diuretics with antibiotics: interactions and safety
Antibiotic courses are common, short-term and often combined with chronic medications such as Diuretics (Diuretics). Most antibiotics do not interfere meaningfully with Amiloride, Bumetanide, Chlorthalidone, Furosemide, Hydrochlorothiazide, Spironolactone, Torsemide at 0.5mg, 1mg, 2mg, 5mg, 10mg, 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 Diuretics agents. Rifampicin has the opposite effect, accelerating metabolism. Most penicillins, cephalosporins, fluoroquinolones and tetracyclines have no clinically meaningful interaction with Amiloride, Bumetanide, Chlorthalidone, Furosemide, Hydrochlorothiazide, Spironolactone, Torsemide at 0.5mg, 1mg, 2mg, 5mg, 10mg.
Practical guidance
According to the prescribing information for Amiloride, Bumetanide, Chlorthalidone, Furosemide, Hydrochlorothiazide, Spironolactone, Torsemide, an antibiotic course should be reviewed by the prescriber or pharmacist for known interactions before Diuretics is co-administered. Adjusted 0.5mg, 1mg, 2mg, 5mg, 10mg dosing or temporary substitution is sometimes preferred for the duration of the antibiotic course.
Frequently asked questions
Can I take Diuretics during an antibiotic course? ▾
For most common antibiotics, yes. A few classes — notably macrolides and azole antifungals — alter how Amiloride, Bumetanide, Chlorthalidone, Furosemide, Hydrochlorothiazide, Spironolactone, Torsemide is metabolised and may need a temporary 0.5mg, 1mg, 2mg, 5mg, 10mg adjustment. The prescribing pharmacist should review any new antibiotic against the existing Diuretics regimen.
Will antibiotics make Diuretics stop working? ▾
Most antibiotics do not affect Diuretics efficacy. Rifampicin and a few others can lower Amiloride, Bumetanide, Chlorthalidone, Furosemide, Hydrochlorothiazide, Spironolactone, Torsemide levels and reduce effect; in those cases the prescriber may adjust the dose during and shortly after the antibiotic course.
