Tolsura is used to treat blastomycosis (infection caused by Blastomyces fungus) and histoplasmosis (infection caused by Histoplasma fungus), which can affect the lungs and other organs. It may also be used for other fungal infections as determined by a healthcare provider.
Tolsura contains itraconazole, an azole antifungal that works by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes. This disruption weakens the fungal cell wall, preventing the fungus from growing and spreading.
Tolsura should not be used by patients with heart failure. It has numerous drug interactions and should be taken with food for optimal absorption. Liver function monitoring may be needed during treatment. Pregnant women should avoid this medication. Always complete the full course of treatment as prescribed.
