Prescription only

Dantrium (dantrolene)

Lowers blood pressure and controls heart rate.

3.9/ 5 average rating with 61 reviewsforPropranolol
Relaxes your muscles.

Dantrium (dantrolene) effectively treats malignant hyperthermia (increased temperature and muscle contractions when receiving anesthesia) and is the only medicine used to treat the condition. Dantrium (dantrolene) is not a first-choice treatment for general muscle spasms because it can damage your liver.

Upsides
  • A first-choice treatment to prevent chest pain (angina).
  • A first-choice treatment for heart failure, heart attack, heart valve disorders, and abnormal heart rhythm.
  • Also treats and prevents many non-heart problems, such as tremors, anxiety, migraines, and liver disease symptoms.
  • Dantrium (dantrolene) effectively treats malignant hyperthermia.
  • Can be used for muscle spasticity if other medications haven't worked.
  • Available as generic.
Downsides
  • Taking a beta blocker might make you feel more tired or out of breath during exercise or normal daily routines. This gets better for most people, but for some might not go away.
  • Has more side effects than some beta blockers because it crosses into the brain and central nervous system.
  • Not a first-choice treatment for high blood pressure according to the latest guidelines, except if you have heart failure or heart disease. As a second choice, your doctor might add it to medicines you're already taking if your blood pressure is still too high.
  • Can hide symptoms of low blood sugar if you're diabetic.
  • You can't miss doses. Stopping Propranolol suddenly can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke.
  • Not a first-choice treatment for muscle spasms because it can cause liver damage.
  • Can cause dizziness, sleepiness, and sometimes severe diarrhea.
  • Needs routine blood tests since it can injure your liver.
  • Dose needs to be increased slowly to minimize side effects.
