Rovamycine (Spiramycin, macrolide antibiotic)

Written by Stephanie Nera, RPh, PharmD · Pharmacology

Updated Jul 26, 2021

Rovamycine (also spelled rovamycin) is the brand name of the generic drug spiramycin. Spiramycin is a macrolide antibiotic that is used to treat certain parasitic infections, particularly toxoplasmosis. It is only available for purchase with a physician’s prescription.

Toxoplasmosis is an infection by the parasite Toxoplasma gondii. This parasite typically does not cause symptoms unless someone is immunocompromised, such as pregnant women or HIV/AIDs patients. Ways this parasite spreads is through eating undercooked meat and shellfish, consuming contaminated water or vegetables, or handling cat feces (poop) or soil that is contaminated with the parasite. Other routes of transmission include mother-to-child and receiving infected organ transplants or blood transfusions.



What is Rovamycine used for?

  • Respiratory tract infections
  • Skin and soft tissue infections
  • Gonorrhea (in patients who are allergic to penicillins)
  • Toxoplasmosis in pregnancy (<18 weeks)

How should I take Rovamycine?
