I wouldn't buy cough drops from Qualitest, much less Valcyte. Here are the excerpts from
an article I originally sent to
@Gingergrrl. It was the first thing that popped up when I Googled "Qualitest quality":
Instead, if you can afford it, I would recommending buying the Cipla generic
Valgan direct from AllDayChemist. Cipla’s bulk manufacturing facilities have been FDA approved for thirty years now, and they undergo regular FDA inspections. They are a top quality generic drug manufacturer. At 900 mg/day, their generic Valgan costs $360/month from AllDayChemist. It typically costs much more from other pharmacies.
