Last Updated: January 29, 2020

Spasms and tense in the body are often the cause of neck and back pain. Usually, regular over-the-counter pain medication may be enough to deal with such problems. In situations where a severe pain takes place, strong muscle relaxers are prescribed. Rx muscle relaxers help to reduce spasms, increase the mobility of the tissues affected, and relieve the patient of the pain that accompanies the issue. Various muscle relaxant drugs have different chemical compositions so that they can give pain relief in different ways. Recognizing their types, common names, and being aware of their potential harm will help to undergo treatment successfully when muscle relaxers prescription is obtained.

Prescription Muscle Relaxers Types

Muscle relaxants are prescribed for treating spasms or spasticity, but the chemical composition required for each medication varies. They are divided by types, and recognizing these types will help to learn how muscle relaxers work. There are antispasmodics, antispastics, and other off-label prescription drugs that can be used instead of prescription muscle relaxers.

It is a centrally-acting skeletal strong muscle relaxant that has FDA-labeled indications for spasticity and spasms that are tied to CNS lesions, such as spinal cord lesions or multiple sclerosis. Baclofen brings relief by blocking the nerve signals sent from the spinal cord, causing the spasm. It is available in tablet form and can be used by people as young as 12 years old.

Off-Label Muscle Relaxants

Commonly known medications that can act as off-label prescription muscle relaxants include:

  • Benzodiazepines: Diazepam, Clonazepam, Alprazolam, Lorazepamcan, etc.
  • Alpha-Agonist Hypotensive Agents: Clonidine,
  • Anti-seizure drugs: Gabapentin,

How To Get Prescribed Muscle Relaxers?

The doctor can diagnose to see if the patient suffers from any health conditions that may affect the function of the drug and be able to prescribe adequate medication and dose. Herbal muscle relaxers can be advised as an alternative for those who can’t obtain muscle relaxers prescription.

Who Can Prescribe Muscle Relaxants?

Can chiropractors prescribe muscle relaxers? While they are licensed to operate in all states in the U.S.A and over 30 countries worldwide, only a few states actually grant permission for them to prescribe drugs. Before receiving a prescription from a chiropractor, find out if they have a license to do so in a state where a patient is located. However, it is still much safer and highly recommended that any muscle relaxer prescriptions should be gotten from a medical doctor, if possible.

Are Muscle Relaxers A Controlled Substance?

These drugs are considered to be controlled substances in the United States. It is illegal to sell or acquire muscle relaxers OTC. The Controlled Substances Act of the United States includes Schedule I to Schedule IV rating scale for controlled substances. Soma, for example, is known to fall under Schedule IV, which means that it is the drug which has a low potential for abuse. Getting high on muscle relaxers can lead to life-threatening circumstances, so the prescribed dose should never be exceeded.

Misuse or abuse of the medication can also lead to muscle relaxant overdose symptoms. They may weaken the body, making it necessary to avoid challenging activities or those that require close attention. Anyone that is found in the habit of misuse, abuse, or excessive dependence on this medication must immediately be taken for professional addiction treatment.
