Foscavir: Uses, Dosage, Demographic, Side Effects, Interactions, and Generic Options Foscavir is the brand name for Foscarnet Sodium, an antiviral medication that is used to treat different types of viral infections, including cytomegalovirus (CMV) retinitis in patients with acquired immunodeficiency syndrome (AIDS) and herpes simplex virus (HSV) infections in patients who are resistant to other antiviral drugs. This article provides comprehensive information about Foscavir, including its uses, dosage, demographic, side effects, interactions, and generic options. Uses Foscavir is primarily used to treat viral infections, such as CMV retinitis and HSV infections. It is also used to treat other types of viral infections, including varicella zoster virus infections, Epstein-Barr virus infections, and human herpesvirus 6 infections. Dosage The dosage of Foscavir depends on the type of viral infection being treated, the patient's age, and other medical conditions. The recommended dosage for CMV retinitis is 60 mg/kg every eight hours, while the recommended dosage for HSV infections is 40 mg/kg every eight hours. The duration of treatment may vary depending on the severity of the infection and the patient's response to treatment. Demographic Foscavir is approved for use in adults and children over the age of 12 years. However, the dosage may need to be adjusted for patients with renal impairment, as Foscavir is primarily eliminated through the kidneys. Side Effects Like any medication, Foscavir can cause side effects. The most common side effects include fever, nausea, vomiting, diarrhea, headache, and rash. Other possible side effects include electrolyte abnormalities, renal toxicity, and hematologic abnormalities. Patients should be closely monitored for signs of electrolyte imbalances, such as hypocalcemia, hypomagnesemia, and hypokalemia, which can be life-threatening. Interactions Foscavir has the potential to interact with other medications. Patients should inform their healthcare provider of all medications they are taking, including prescription drugs, over-the-counter medications, and supplements. Foscavir should not be used in combination with other medications that can cause renal toxicity, such as aminoglycoside antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs). Generic Options Foscavir is available as the generic drug Foscarnet Sodium. The generic medication has the same active ingredient and is equally effective as the brand-name drug. The generic medication may be less expensive than the brand-name drug, making it a more affordable option for some patients.
