Spørg lægen eller apoteket til råds inden De tager Revatio, hvis De tager medicin, der indeholder erythromycin, clarithromycin, telithromycin (antibiotika til at behandle visse typer bakterieinfektioner), saquinavir (mod HIV) eller nefazodon (ved depression), da dosis måske skal justeres.
If you are taking medicines containing erythromycin, clarithromycin, telithromycin (these are antibiotics used to treat certain bacterial infections), saquinavir (for HIV) or nefazodone (for mental depression), ask your doctor or pharmacist for advice before taking Revatio, as your dose may need to be adjusted.
