Question 2

What kind of drug is vancomycin?

Accepted Answer

The FDA classifies vancomycin as a glycopeptide antibacterial. If you are checking whether it is safe to combine with something else, the class is what matters — two drugs from the same class usually should not be stacked.

Question 3

Can you take vancomycin with other medicines?

Accepted Answer

It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run vancomycin against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.

Question 4

What brand names is vancomycin sold under?

Accepted Answer

We track 4 vancomycin-containing products in the U.S.: Firvanq Kit, Tyzavan, Vancomycin Hydrochloride and Vancocin Hydrochloride. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.

Question 5

What forms does vancomycin come in?

Accepted Answer

Across the brands we track, vancomycin is currently marketed as kit, injectable, solution, capsule and powder, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.

Question 6

Is there a generic vancomycin?

Accepted Answer

Yes. Our catalog lists 2 generic vancomycin products alongside the brand versions. A generic has the same active ingredient and must meet the FDA's bioequivalence standard; it usually costs less. Ask your pharmacist which one your plan covers.

Question 7

Has vancomycin been recalled?

Accepted Answer

The FDA's Enforcement database lists at least 5 recall records whose product description mentions vancomycin. The most recent: Vancomycin HCL (Mar 20, 2026). A recall applies to specific lots, not to the drug as a whole — check the record for the affected lot numbers.
