Upsides
  • A first-choice blood pressure treatment for many people.
  • Calcium channel blockers work especially well for African Americans to lower blood pressure.
  • Lowers the risk of heart attack and stroke.
  • Prevents heart-related chest pain (angina) if you take it regularly.
  • Each dose lasts longer than other calcium channel blockers, which keeps blood pressure consistent without big ups and downs.
  • Particularly good at lowering systolic blood pressure (the top number), so it's a good option for older people who can commonly get high blood pressure only in the top number.
  • Can be added to other blood pressure-lowering medicines if you need additional blood pressure control.
  • Makes urination easier in men with an enlarged prostate.
  • Helps people with PTSD get better sleep with fewer, less-intense nightmares.
Downsides
  • Calcium channel blockers can cause swelling in your limbs. If this happens for you, it probably won't get better over time, so talk to your doctor about alternatives if it bothers you.
  • Women are more likely to have side effects (especially swelling) from Amlodipine than men.
  • Some people might experience flushing with this medication.
  • You can't miss doses. Stopping Amlodipine suddenly can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke.
  • If you have severe heart disease, using Amlodipine might increase your risk of chest pain or heart attack during the time right after starting the medication or raising the dosage.
  • Might not be a good choice if you have liver disease.
  • Not the best medicine to lower blood pressure by itself.
  • Likely to cause orthostatic hypotension. This means dizziness when you change positions (like standing up) because your blood pressure doesn't adjust quickly enough.
  • Not preferred for people 65 years or older.
