Sofosbuvir
About Sofosbuvir
Sofosbuvir is a prescription medicine used to treat chronic hepatitis C, a long-term viral infection that causes liver inflammation and damage. The primary medical purpose of this medicine is to clear the hepatitis C virus from your bloodstream. It is almost always used in combination with other direct-acting antiviral medications to ensure the infection is completely cured.
For this treatment to be successful, you must take Sofosbuvir consistently every single day without missing a dose. You can take this tablet with or without food, making it easy to schedule around your daily routine. Adopting a nutritious diet, maintaining good hydration, and avoiding substances that strain the liver can significantly support your body's recovery during treatment.
While Sofosbuvir is generally well-tolerated, some people may experience mild, manageable side effects like headache or fatigue. If you experience severe symptoms, such as signs of a serious allergic reaction or rapid worsening of liver function, seek emergency medical care immediately.
Talk to your doctor before starting this medicine if you have certain pre-existing health conditions, such as a history of hepatitis B infection, kidney disease, or severe liver impairment. Do not take this if you have a known allergy to any of its components or if you are taking specific medications that severely interact with it.
This medicine can interact with several other drugs, including herbal products like St. John's wort, which can make the antiviral therapy much less effective. If you are pregnant, breastfeeding, or planning a family, you must consult your doctor or pharmacist before starting Sofosbuvir, as it is used in combinations that can pose risks.

The symptoms may not appear immediately. Some may take between 2 to 12 weeks to appear.
