You may be interested at these reviews (Write a review):

  • Ranexa and erectile dysfunction
    I have experienced moderate ED with taking multiple heart and NO meds. This has been manageable and acceptable. Cardiologist added Ranexa (Ranalozine) 3 weeks ago and I am now experiencing complete erectile and ejaculatory failure.
  • Tykosin and spontaneous erections
    After 15 minutes of taking Tikosyn 250 size I get spontaneous erections that remain in duration for extended periods of one hour or more. These happen several times during a 12 hour dose cycle.
  • Meds i take at night
    I take amlodipine coreg clonidine lovastatin isosorbide every night and it brings my pressure way down
  • Taste loss while taking lisinopril
    I have severe loss of taste and appetite since starting lisinopril . I was unsure what the cause was until finding your site. My physician did not know what was causing it and did not even try to find out. In fact she doubled the dose I was taking .
  • Metoprolol & lisinopril, vs. carvedilol, lisinopril and warfarin
    Lisinopril 25mg provokes horrific depression, despair, inability to navigate back to upbeat, creative state and fear for survival. Dizziness, crippling vertigo, etc every time I move from rest. Reducing dose to 2.5mg makes side effects tolerable, with no noticeable change in therapeutic effect.

    Carvedilol caused renal failure, edema, coughing, panic-inducing painful allergic skin rashes, necrosis, healing took weeks where it had taken a day or less. Unable to walk up or odnw stairs unaided. Fell a lot Vision blurred, especially at night and when seeking perspective : driving.

    Warfarin made me feel like my body was made up of burdens foreign matter. Contraindicated diet was a blow to my post-domestic-violence, with sexual assaults, fragile ego, and capped the hopelessness triune of impacts.

    Metoprolol has caused awful heartburn since the first dose, with bloating and gas. Heartburn begins 12hrs after eating, very late at night. It keeps me from most activities. Very painful. Digestive upset I thought was from IV radiation / imaging seems to be metoprolol's doing.

  • Is there an adverse reaction to taking ondansetron with carvedilol and Diltiazem? I have been taking the last two for some time. I added ondansetron (for nausea) yesterday, and when taken at the same time, made me feel very nervous and shaky. Thank you!
