Hello OregonDaisy, Dr James was not suggesting that you return Harvoni generic at all, you definitely need to take it, he was suggesting that you add another medication (Daclatasvir) to your Harvoni treatment. This will enable you to take antacids, such as Protonix, without worrying about potential medications interactions. You do need a prescription for Daclatasvir if you decide to get it, please let us know if you need help with that.
The alternative would be to take the lowest possible dose of Protonix 1 hour after taking Harvoni, and hopefully everything will go smoothly. If you prefer to take Protonix at night, you can take Harvoni at night too with a late dinner (instead of in the morning), then take Protonix 1 hour after that.
