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.
  • Available in a weekly patch for people that aren't good at taking medicine by mouth.
  • Works in the brain, so it can help treat some nervous system and psychiatric conditions.
  • Under the brand name Kapvay, it's used to treat ADHD in children and teenagers.
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.
  • Has a lot of side effects compared to other blood pressure-lowering medicine because it works in the brain.
  • The pill form can make some people sleepy, dizzy, and have dry mouth.
  • You can't miss doses. Stopping Clonidine suddenly can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke.
