What is an Over the Counter Muscle Relaxer?

Over-the-counter muscle relaxers are the medications that you can find while perusing the aisles at your convenience store or local pharmacy. Most of them are household names, and it’s not uncommon to keep them on hand, stored in a medicine cabinet, just in case. Even though over-the-counter (OTC) medications are easy to purchase, they’ll do the job for many pains and aches, and doctors often recommend them before prescribing more powerful treatment options.

Nonsteroidal anti-inflammatory drugs (NSAIDs) like Ibuprofen and Naproxen are some of the most common OTC muscle relaxers medications for pain in general. They might not have the same potency as high-grade and prescribed muscle relaxers, but they’re still effective and have very few side effects. 

Over the Counter Muscle Relaxer
Like all other medications, over the counter muscle relaxers should not be shared, misused, or abused.

Common / Best Over the Counter Muscle Relaxers

Prescription muscle relaxants may help reduce pain and improve movement and range of motion, but doctors will likely recommend that you first try acetaminophen or a nonsteroidal anti-inflammatory drug (NSAID) like Ibuprofen (Advil), and Naproxen (Aleve). In some cases, these over-the-counter muscle relaxers will be enough to help alleviate your pain.

Acetaminophen (Tylenol)

Tylenol, is also known under the generic name acetaminophen. It is used to treat pain and discomfort associated with strains, sprains, spasms, or other muscle injuries. Acetaminophen works by raising the pain threshold a person feels – meaning it is harder for a person to feel pain. This muscle relaxant otc can reduce fever by telling the heat-regulating center of the brain to lower the body’s temperature when it is too high. It is also thought to reduce the number of chemicals in the brain that causes inflammation and swelling.

Acetaminophen was approved for use by the U.S. Food and Drug Administration (FDA)[1] in 1951. While Tylenol and generic acetaminophen do not require a prescription, Tylenol 3 does. This is because Tylenol 3 is a stronger version of regular Tylenol. Tylenol 3 contains acetaminophen as well as a high amount of codeine.

Acetaminophen as a Recreational Drug

Acetaminophen (Tylenol) isn’t addictive and individuals don’t take it to get high. However, it is an active ingredient in many painkillers, such as Percocet and Vicodin, which are abused for their highs. It is the acetaminophen contained in these drugs that is often the most damaging.

Overdose from this over counter muscle relaxant causes about 60,000 individuals each year to go to the hospital, several hundred of which die from associated liver failure. Large doses or chronic use can lead to liver damage, especially when used in combination with alcohol or other drugs.

If a person who is abusing acetaminophen suddenly stops misusing the over the counter muscle relaxer, withdrawal symptoms can occur. These withdrawal symptoms may range from bone and muscle pain and restlessness to diarrhea and vomiting. It is important for people with an acetaminophen addiction to seek out the proper addiction recovery treatment from qualified medical professionals.

Side Effects of Acetaminophen Abuse

Acetaminophen is most commonly misused as a recreational drug in combination with other medications [2]. On their own, these muscle relaxers otc are widely accepted to be a safe drug and are easily accessible.

More powerful forms of acetaminophen, however, such as Tylenol 3, can only be purchased through a doctor’s prescription, as it also contains a significant amount of codeine, another painkilling drug. Acetaminophen alone is not particularly habit-forming, but the codeine in Tylenol 3 can lead to dependency.

The codeine in Tylenol 3 can cause feelings of euphoria, which leads some people to abuse the drug. Tylenol 3 has also been shown to enhance the effects of other drugs, such as alcohol, narcotics, tranquilizers, general anesthetics, sedative-hypnotics, and other central nervous systems (CNS) depressants. Mixing acetaminophen with any of these drugs increases the risk of experiencing the adverse side effects of each drug.

In addition to the complications posed by acetaminophen abuse, chronic overuse of painkillers can lead to psychological and physical dependence, as well as the associated withdrawal symptoms when drug use is stopped.

Acetaminophen Liver Damage

Acetaminophen poisoning in the form of severe liver damage can happen when too much of the drug has been taken. Whether intentional or accidental, an overdose of this drug requires immediate medical attention to prevent further damage to the body. Symptoms of liver damage include:

Muscle relaxers over the counter should also never be combined with antihistamines or alcohol. Despite the severity of muscle relaxer side effects, quitting them can be difficult to do for someone who has become dependent on this drug.

  • Fatigue
  • Yellowing of skin or eyes
  • Pain in abdomen
  • Nausea and vomiting
  • Loss of appetite
  • Excessive sweating
  • Dark urine and stools
  • Pale skin color
  • Unusual bruising
  • Unusual bleeding

More complications can occur with acetaminophen as it interacts with other drugs. Antifungals, antibiotics, sulfa drugs, nonsteroidal anti-inflammatory drugs (NSAIDs), and birth control pills, as well as medications for the treatment of cancer, high blood pressure, high cholesterol, arthritis, seizures, HIV/AIDS, and psychiatric conditions, can all be affected by this over the counter muscle relaxer.

Acetaminophen’s Reactions with Alcohol

Alcohol abuse combined with acetaminophen use can increase the risk of stomach bleeding and liver damage. Any drugs or substance, for that matter, that puts prolonged stress on the liver or kidney poses significant health threats, especially when mixed with acetaminophen. The U.S. Food and Drug Administration (FDA) recommends not drinking more than three alcoholic beverages in one day if planning on taking acetaminophen.

Naproxen (Aleve)

Naproxen (Aleve) is a popular and accessible nonsteroidal anti-inflammatory drug. It’s useful in treating muscle pain, migraines, osteoarthritis, headaches, cramps, fever, and minor injuries. The drug’s daily usage is generally safe when someone is following the instructions. However, the misuse and abuse of this over the counter muscle relaxer’s can lead to a risk of addiction. Naproxen abuse is dangerous and can cause severe health issues [3].

Naproxen is both a prescription and OTC medicine. One can buy a prescription Naproxen, in which case it is available as a tablet or an effervescent. Furthermore, its classification as a painkiller means the prescription is necessary, especially for patients suffering from different types of tissue inflammation.

The drug is available as an over-the-counter (OTC) drug with the brand name Aleve. At the same time, prescription Naproxen is known as Naprosyn and Anaprox.
