Frequently Asked Questions

Sofosbuvir ke side effects kya hain?

Common side effects include fatigue, headache, nausea, and insomnia. Anaemia can also occur when taken with Ribavirin. Serious side effect: when taken with amiodarone, heart rate can become very slow — this can be fatal. Never take them together.

Sofosbuvir se anaemia kyun hoti hai?

Sofosbuvir itself does not cause anaemia — but Ribavirin destroys red blood cells. For this reason, CBC (blood count) must be monitored regularly during treatment.

Kya Sofosbuvir aur Amiodarone sath le sakte hain?

ABSOLUTELY NOT. The combination of Sofosbuvir and Amiodarone is CONTRAINDICATED. Taking both together has been reported to cause severe or fatal bradycardia. If you are taking amiodarone, inform your doctor immediately.

Hepatitis B reactivation kya hota hai?

If someone has had a prior Hepatitis B infection, it can reactivate when HCV treatment is started. For this reason, an HBsAg test is required before starting Sofosbuvir. If needed, Hepatitis B treatment is given beforehand or concurrently.

Sofosbuvir se kaun se symptoms par foran doctor se milna chahiye?

Slowing heart rate or palpitations, worsening jaundice, extreme fatigue or shortness of breath, yellow eyes — these are all emergency signs. Contact a doctor or hospital immediately.
