supraventricular tachycardia
"I've been on Toprol XL for 15 years ..started on 50 mg once per day then dropped to 25 mg ..experienced symptoms again then was changed to bystolic but only for a short time ..the doc said toprol was more for my problem so changed back and now on toprol xl 50 mg per day again ..I tried the generic 4 times and always have to take the brand .The genetic didn't work for me after the fourth day of trying it...but now I have severe dizziness floating and faint feeling spells that are worser with my period and noticed my blood pressure getting very low when resting 87/54 or 85/58...so I'm debating on going back to 25 mg per day ..anyone had this experience with Toprol xl?"
