I take Telmisartin 40mg at bedtime, Hydrochlorothiazide 25mg and Simvastatin 40mg in the morning. I also have Hydralazine 10mg (1/2 tablet) if needed for occasional "spiking" of blood pressure. However, over the weekend, my blood pressure reading dropped to 70/40, for which I drank water, ate some salt, quick recovery. Otherwise my blood pressure stays fairly "normal." Suggestions?
