Cardiac failure symptoms and conditions

headache immediately after taking synthroid. Taking generic...
I hear that 200mcg of Selenium is a natural treatment. I may try that..I'm not going to cont. taking this crap. I have read it can cause cardiac failure too. Who wants all that crap. I feel bad enough as it is with allergies and hormone imbalance(Perimenopause).

Does anyone know if Singulair can cause heart valve problems? I just found out that I have Mitral Valve Prolapse, and have never had any problems until after taking Singulair. Any info would be greatly appreciated...especially from Concerned Citizen if he's out there...

Thanks,

K.

I just finished my seventh day of Avelox today for rhinitis (sinus). The dry mouth and throat is very bad. I wake up about twice a night to drink water. My mouth and throat gets so dry. It even gets dry and sticky throughout the day. I am drinking so much water. I have noticed about an hour after I take it, I get dizzy and become very anxious. I even start thinking about all of my symptoms and begin to freak out. I have had about two panic attacks this week. I do not like the changes it has done to me. I have also been very emotional and sad. I think I have cried about three times this week. I am glad I am finished...no more depression! My sinus infection is better though.
