After asking my pharmacist not to dispense me Teva Liothyronine as I’m not doing at all well on it, I’ve just opened my latest prescription to find... three bottles of Teva! I rang the pharmacist who told me they can’t request a specific brand and I have to get what I’m given. Surely this can’t be right. She also mentioned the cost of Mercury Lio and I said I was aware of the cost but my doc had prescribed it for almost two years and I’d been doing really well on it. How do I make sure I don’t get Teva again? Any answers gratefully received.
