Could changing generic brand of metoprolol tartrate caused problems?

Its the same medication, however it could be a different base, and that could be causing you trouble. I would ask my pharmacist if he can get you a list of the inactive ingredients in both pills. One might be absorbing better then the other. Or an additive could be a problem for you.

YES! My husband was switched yesterday from the Mylan to the Curaco Metropolol and has been on the Mylan generic for at least two years with no problems. This morning, two hours after taking the Curaco generic, he started feeling disoriented, dizzy and having vision problems with the Curaco. We have called the drugstore and they agreed to special order the Mylan lab generic. Very weird.

Yes, I have the same symptoms. I especially noticed after and during my routine exercise. I wonder how many people have gone off to the emergency room as a result of this switch?

My pharmacy changed from Mylan to Carac. After 2 days my BP was out of control and I went to the ER and was admitted to hospital. The stress test showed no problems and my cardiologist blamed to much salt in my diet (which hadn't really changed that much). The only real change was the prescription. I will insist on a different mfg. now. The problem was not me.

I am having similar problems. I am call g pharmacist andc doctor if need be.

I recently was switched by Walgreens to the Curaco version of Metropolol Tartrate at Walgreens when I moved by prescription from Mayo. It does not work as well. My heart is racing 8 to 10 hours later. My 50 mg pills are making me anxious.

My pharmacy switched my Metoprolol from Mylan to Caraco and within days I felt like my heart was doing cartwheels. It would race and then I would feel irregular heartbeats. I always maintained a good blood pressure while on the Mylan brand and had no side effects. I took my blood pressure and it was 167/100! It was a struggle to find a pharmacy that still has the Mylan brand, and when I did, within 5 hours, my heart was back to normal, and my blood pressure is now 125/78. I know they say the pills are the same from brand to brand, but the inactive ingredients are not, and not everyone's body absorbs the medication properly when the inactive ingredients are changed. I thought I was dying! So scary. I wanted to share this in case someone else is experiencing similar changes, I found that CVS still carries the Mylan brand.
