Can tizanidine cause low heart rate?
Increased side effects can include decreased blood pressure, decreased heart rate, or extreme drowsiness. Acyclovir. Increased side effects can include decreased blood pressure, decreased heart rate, or extreme drowsiness.
Can tizanidine cause heart arrhythmia?
Background: Tizanidine (Zanaflex) is a centrally acting imidazoline muscle relaxant that is structurally similar to clonidine (α(2)-adrenergic agonist) but not to other myorelaxants such as baclofen or benzodiazepines. Interestingly, cardiac arrhythmias and QT interval prolongation have been reported with tizanidine.
Which muscle relaxant causes bradycardia?
Tizanidine, an α2-adrenergic receptor agonist, is a widely used medication for the treatment of muscle spasticity and pain. However, adverse events have been reported with its use, including somnolence, dry mouth, asthenia, and dizziness. Bradycardia is among the reported events following tizanidine overdose.
Will muscle relaxers raise your heart rate?
Onset of action of muscle relaxant, was fastest with rocuronium (group R=132.7 +/- 0.3 sec, P=182.6 +/- 68.5 sec, V= 144.8 +/- 46.1 sec, Group P vs Group R). To conclude, pancuronium causes significant increase in heart rate and should be preferred in patients with regurgitant lesions having slower baseline heart rate.
Do muscle relaxers affect blood pressure?
When certain drugs are used with cyclobenzaprine, they may not work as well. An example of these drugs includes guanethidine. Cyclobenzaprine can block the blood pressure-lowering effect of guanethidine. This means your blood pressure may increase.

Do muscle relaxers slow down your heart rate?
In group R, the heart rate decreased 5 min after injection of muscle relaxant from 93.9 +/- 21.3 to 82.4 +/- 20.7 beats/min (p<0.001). However, it increased to 128.3 +/- 25.8 beats/min (p<0.001) following intubation and returned to baseline at 5 min after intubation.
Can methocarbamol cause bradycardia?
General side effects of methocarbamol can include tachycardia (rapid heart rate), bradycardia (slow heart rate), dizziness, blurred vision, nausea, headache, confusion, drowsiness, clumsiness, constipation, memory problems and flushed/itchy skin.
