since your heart is a muscle if you take a muscle relaxer does it relax your heart too?

Question

My daughter was worried and wanted to know since I took a muscle relaxer

Answer 1

Your heart is made of a different kind of muscle than your biceps or abs. Your abs are made of skeletal muscle, because they move the skeleton, which results in movement. Your heart is made of cardiac muscle which specializes in rhythmic contractions producing heartbeats. I would think that if you took a muscle relaxer, it would only have an effect on your "muscles," or skeletal muscles, and have no effect on any other kind of muscles in your body.

Answer 2

Below I listed the cardiovascular effects of three muscle relaxers. As you can see, some decreases blood pressure and some increases blood pressure, etc. As with any drug, each one works differently. If you edit your question and tell me which type of muscle relaxer you are taking I will try to answer your question.

Cardiovascular effects: Curare has no direct action on the heart but there is often a slight fall in the blood pressure secondary to a vasodilating effect via the sympathetic ganglia. In the presence of volatile agents the blood pressure fall may be greater. Care should be taken with this combination in hypotensive patients.

Cardiovascular effects: Gallamine produces an increase in heart rate, usually by 20-30 beats/minute due to an inhibitory action on the vagal supply to the heart. Blood pressure is usually unaltered unless bradycardia was previously present.

Cardiovascular effects: After an i.v. dose there is frequently a slight fall in blood pressure due to vasodilation secondary to a degree of sympathetic blockade. This is occasionally accompanied by a tachycardia. Alcuronium is associated with a slightly higher incidence of anaphylactoid reactions than other non-depolarising muscle relaxants.

GOOD LUCK!
