Over-the-counter muscle relaxers imply groups of spasmolytic drugs that reduce pain, spasms and strain in the skeletal muscles, and can be purchased without being prescribed by a medical professional. The current article provides a brief account of some OTC muscle relaxants along with their brand names and common usage.
Muscle relaxers are drugs that alleviate pain, stiffness, swelling, or any kind of discomfort due to sprains, muscle spasms, muscle injuries and muscular disorders.
They do not heal injuries or defects but help in relaxing the muscles, thereby relieving pain. Muscle relaxers include the following two categories of drugs depending on their mode of action:
Spasmolytics: These are also known as centrally acting muscle relaxants, as they act through the central nervous system to reduce muscle stiffness and muscle pain.
Neuromuscular-blocking agents: These drugs act via the peripheral nervous system at the neuromuscular junctions, and paralyze the skeletal muscles. They are generally used in conjunction with anesthetics during various surgical procedures.
The term ‘muscle relaxers’ generally implies spasmolytic drugs, a few of which are available as non-prescription drugs in certain non-US countries. Given below are a few commonly used muscle relaxants. The availability status of each drug varies from country to country.
Muscle Relaxers Available OTC
Over-the-counter muscle relaxer medications include a group of different drugs that can be purchased without the prescription from a medical expert. Such OTC muscle relaxants are often used for relief from back pain as well as muscle spasms, strain and cramps.
Although available as prescription drugs in most countries, the following muscle relaxants are allowed to be sold as non-prescription drugs in certain countries.

It is available as over-the-counter tablets and oral solutions in Belgium, Canada, Thailand and Mexico. It is often prescribed for alleviating the muscle pain arising due to injury, sprain, spasms and sciatica. It acts by blocking the neurotransmitter called acetylcholine, thus reducing pain.

Prescription Muscle Relaxers
Almost all the muscle relaxers are prescription drugs. These drugs may cause adverse effects leading to cardiac and hepatic problems in certain individuals. It is imperative to consider the medical history, risks and age, before deciding the drug and the dosage. Hence, in most of the countries, including USA, their availability is strictly prescription-based.

Baclofen
Brand Names

Baclofen is prescribed to minimize the frequency and severity of muscle spasms arising due to neurological disorders like multiple sclerosis and cerebral palsy.

Muscle relaxers are used in the treatment of several conditions and diseases involving musculoskeletal problems as well as neuromuscular ailments. They help to provide relief from the pain and discomfort associated with such conditions. However, each drug has its own set of side effects and limitations. Hence, it is essential to seek professional consultation before resorting to such medications.
