Carisoprodol and Flexeril

Cyclobenzaprine and Soma are both skeletal muscle relaxants that are used for short periods. They treat muscular pain and other associated pains as well. 


Flexeril is recommended along with physical therapy and rest for the best effects on our health. Acute skeletal conditions like muscle spasms are cured with this drug. This medication is not effective when there is a nerve problem. 


The mechanism of action of Soma is not properly known. There isn’t much information regarding the mechanism of action of the Carisoprodol drug. It is thought to alter communication among nerves in those parts of the brain that controls the pain sensations. 


The recommended dosage of flexeril is 5-10mg three times daily. This is for the immediate-release tablets. The advised dosage for carisoprodol is 250-350mg three times daily.

Do muscle relaxers cause weight gain?

The ailments of the back and other parts of the body that involve our muscles are treated with the help of muscle relaxants. It is found that muscle relaxers do not directly contribute to weight gain or loss. 


It means that there is an indirect effect of these kinds of medications on weight. One of the reasons for weight gain is seen in the form of reduced activity. Healing from an injury requires a dedicated period of rest. 


During this rest period, there is little to no activity. As a result of this, there can be a significant increase in weight. 


When muscle relaxers are taken for longer durations, one may notice an increase in body mass. There is a loss of activity and less physical movement, which indirectly results in weight gain.  


Weight gain or loss usually depends on individual to individual. The body structure of every individual is different, and the functioning also varies. The effects of the muscle relaxants would also vary from person to person. 


It is necessary to keep a close eye on the fluctuations in the weight of an individual when on a treatment course of skeletal muscle relaxants.


There is an indirect weight gain associated with the use of Flexeril. There is little information available regarding this topic, but it is something that is a part of experiential knowledge. 


Muscle relaxers usually provide a relieving effect on the muscles in our body. 

Carisoprodol and flexeril are two musculoskeletal muscle relaxants that are effective. The doctor provides the dosage and usage instructions to the patients who require them.
