About Xapavir 50 Tablet

Xapavir 50 Tablet is a prescription medication used to treat Human Immunodeficiency Virus type 1 (HIV-1) infection in adults and children. It belongs to a group of medicines called integrase inhibitors, which help lower the amount of HIV in your body. By keeping the virus under control, this medicine supports your immune system and helps protect you from developing serious infections.

For this medicine to work effectively, you must take it consistently every single day at the same time, exactly as prescribed. You can take this tablet with or without food, making it easy to fit into your daily routine. Adopting a balanced diet and reducing stress can further support your overall immune health while you are on this treatment.

While taking Xapavir 50 Tablet , some people may experience mild side effects like trouble sleeping, headache, or feeling tired. However, you should contact your doctor immediately if you experience signs of liver damage, such as yellowing of your skin or eyes, or severe allergic reactions like skin rashes.

Do not take this if you are allergic to any of its ingredients or if you are taking certain medications like dofetilide. Before starting, tell your healthcare provider if you have a history of liver disease or kidney problems, as they may need to monitor your health closely.

This medicine can interact with certain mineral supplements, alcohol, and other prescription medications, which can lower its absorption or increase side effects. If you are pregnant, planning to become pregnant, breastfeeding, or are an elderly individual, consult your doctor to discuss the risks and benefits before starting treatment.

Uses of Xapavir 50 Tablet

Xapavir 50 Tablet may be prescribed to manage the following conditions:

How Xapavir 50 Tablet Works

Xapavir 50 Tablet contains dolutegravir. It belongs to a class of antiretroviral drugs known as integrase strand transfer inhibitors (INSTIs). To reproduce, the HIV virus needs to insert its own genetic material into your healthy immune cells. It does this using a specific viral protein called integrase. Xapavir 50 Tablet works by blocking the action of the integrase protein. By binding to this enzyme, the medicine prevents the virus from multiplying and spreading to new cells. As a result, the amount of virus in your body decreases, allowing your immune system to better protect you from other illnesses.
