Verelan PM Reviews

For High Blood Pressure "I have had excellent results with this medication and only minor side effects (occasional constipation). I am a long-time calcium channel blocker user, and so far it has been an excellent prescription."


For Cluster Headaches "My neurologist put me on just about every preventative medicine on the market, and none helped stop my clusters. A high dose of Verapamil ER finally did the trick (240 mg 3x a day). After almost 25 years of episodic cluster headaches, I have finally been virtually headache-free for about 3 years now! I am a bit worried about the side effects of taking such a high dose for such an extended time, though. I've recently been having some voice issues, and I'm wondering if there is a correlation."


For High Blood Pressure "I have been on Verapamil 200 mg ER for two months. Recently, I started getting palpitations, feeling dizzy, skipped beats, and fluttering and coughing sensation in my throat area and slow HB. I called my doctor and lowered my dose to 100 mg and he scheduled me for a halter monitor to see if it’s the medication. I am hoping it is and maybe he can switch me back to toprol xr."
