Foscarnet is an antiviral medication mainly used to treat severe infections caused by viruses such as cytomegalovirus (CMV) or herpes simplex, especially in patients with weakened immune systems, like those with HIV/AIDS or transplant recipients. It works by inhibiting viral replication, helping to control the infection when other treatments are ineffective or cannot be used.

Foscarnet is usually administered intravenously under strict medical supervision, as it requires careful monitoring of kidney function and electrolyte balance. The dose and duration of treatment are determined by the doctor based on the severity of the infection and the patient's overall condition.

Common side effects include kidney function disturbances, imbalances in blood salts (such as calcium, magnesium, or potassium), nausea, vomiting, and reactions at the injection site. In rare cases, seizures or other severe reactions may occur, making constant monitoring essential.

Foscarnet is an important medication for patients with resistant viral infections, but its use requires close medical supervision to prevent complications and ensure treatment effectiveness.
