I'm taking verapamil for high blood pressure and clozapine can I use the psyllium which is fiber to lose wait?

Psyllium. Yes, you can use psyllium with these medicines, but i would take it separately from them so that it doesn't interfere with absorption. Also, if concerned about weight, you'll need a more detailed plan than taking psyllium -- you'll need both exercise & healthy diet, eliminating processed foods with unhealthy fat and high-sugar carbs. Talk with your doctor about this -- nutritionist can help!
