Verapamil is a calcium channel blocker used to treat irregular heartbeats (arrhythmias) and high blood pressure. It relaxes your blood vessels so your heart does not have to pump as hard. It also increases the supply of blood and oxygen to the heart to control chest pain (angina).

10 patient evaluations for Verapamil

Feb 24, 2016 (Started Feb 20, 2016)

  • Effectiveness
    Slight (for postural orthostatic tachycardia syndrome)
  • Side effects
    Severe (headaches)
  • Adherence
    Always
  • Burden
    A little hard to take
Dosage: 120 mg Daily
Advice & Tips: This was the second time I tried to take this med, and four days was all I could possibly manage; the constant headache was severe and debilitating. It did lower my heartrate a little, but not nearly enough to make this a viable treatment for me.
Cost: < $25 monthly
