Isavuconazonium Injection

Isavuconazonium injection is used to treat serious fungal infections such as invasive aspergillosis (a fungal infection that begins in the lungs and spreads through the bloodstream to other organs) and invasive mucormycosis (a fungal infection that usually begins in the sinuses, brain, or lungs). Isavuconazonium injection is in a class of medications called azole antifungals. It works by slowing the growth of fungi that cause infection.

Inflated pharmaceutical prices are another huge factor in the steep cost of healthcare. Americans spend an average of $858 per person on prescription drugs, according to Vox. That’s about twice as much as people in Australia spend on prescriptions. It’s three times the amount paid by people in The Netherlands.
