Have HBP..doctor changed my meds from coozar 100mg because it produced cough and didnt work to lower my BP..She prescribed lisinopril 20mg and verapamil 120mg... also a heart monitor for 24 hrs since i've been having strong palpitations and even dizziness... maybe i should wait til the heart monitor thing, this way we'll know about the electric conduction of the heart before it take verapamil? By the way, BP is normal now with the new med of lisinopril 20mg
