Was this refill for the increased dosage a mistake on the part of the pharmacist? Or was it a new Rx called in by your doctor?
Interesting though, that the increased dosage of Diovan seems to have helped with your "head" palpitations.
I would definitely double check with your doctor that he/she indeed wants you on the upped dose, that it was no mistake on the phamacist's part, and explain you even feel better on it.
