Hello Jack,
Beacon and Incepta are two quality trustworthy Pharma companies from Bangladesh. Both produce a co-formulated single pill version of Sofosbuvir + Daclatasvir – Darvoni and Corevigen respectively.
Anything you read about Sofosbuvir + Daclatasvir on the forum is applicable.
Most of the side effects are from Sofosbuvir, and are usually mild and short lived.
Fatigue, headache, insomnia and stomach upset are the most common.
Daclatasvir interacts with a few medicines and foods – there is a lot on that here.
