What is clarithromycin and how does it work?
Clarithromycin is a macrolide antibiotic, the same drug class as azithromycin and erythromycin. It works by stopping bacteria from making the proteins they need to grow and multiply, which helps your body clear the infection. It is FDA-approved to treat several bacterial infections, including community-acquired pneumonia, acute worsening (exacerbations) of chronic bronchitis, acute maxillary sinusitis, pharyngitis or tonsillitis, and uncomplicated skin and skin-structure infections.
Clarithromycin is also used to treat and help prevent disseminated Mycobacterium avium complex (MAC) disease, and it is a component of combination therapy, taken with a proton pump inhibitor such as omeprazole and often amoxicillin, to eradicate H. pylori infection and treat associated duodenal ulcers. It was originally sold under the brand names Biaxin and Biaxin XL, though the brand has largely been discontinued in the US; the generic is what pharmacies dispense today.
Clarithromycin cost and coupons without insurance
Clarithromycin is available as an FDA-approved generic, so it is generally one of the more affordable antibiotic options, even if you are paying cash without insurance. There is no manufacturer savings card for clarithromycin. The bigger factor in what you pay is where you fill it: the same prescription can cost very differently from one pharmacy to another, sometimes even between two stores on the same street.
That is where comparing helps. Rx.com checks prices across more than 60,000 pharmacies so you can see who has the best cash price near you and use a free discount coupon at the counter. Enter your ZIP above to see today's price for your dose and quantity, then show the coupon on your phone or print it.
How clarithromycin compares to other antibiotics
Clarithromycin is one of several antibiotics a provider may choose depending on the type of infection, your allergies, and local resistance patterns. Related options include:
- Azithromycin — a fellow macrolide often taken as a shorter course; it has a different dosing schedule and interaction profile.
- Erythromycin — the older macrolide clarithromycin was derived from.
- Amoxicillin — a penicillin-class antibiotic, and a common partner in H. pylori combination therapy.
- Doxycycline — a tetracycline used for some overlapping respiratory and skin infections.
Only your prescriber can decide which antibiotic is right for you. If you have been prescribed a specific one, you can compare its cash price on Rx.com the same way.
Clarithromycin safety and interactions
Clarithromycin does not carry an FDA boxed warning, but it has important safety considerations. It can prolong the QT interval and, rarely, cause serious heart rhythm problems (including torsades de pointes), so it should be avoided in people with a prolonged QT, low potassium, or who take other QT-prolonging medicines. It is a potent CYP3A4 inhibitor with many drug interactions and is contraindicated with certain medicines, including cisapride, pimozide, ergotamine or dihydroergotamine, and specific uses of the statins lovastatin and simvastatin (because of a rhabdomyolysis risk). Colchicine should not be combined with clarithromycin in people with kidney or liver impairment.
Other risks include liver injury, C. difficile-associated diarrhea (which can appear up to about two months after treatment), and rare but serious skin reactions. Clarithromycin may cause fetal harm and is generally avoided in pregnancy unless there is no suitable alternative. Tell your provider and pharmacist about every medicine and supplement you take, and take the full course exactly as prescribed.
