Signs Of A Flexeril Addiction – Professionals generally consider Flexeril to be nonaddictive; however, there is evidence that Flexeril addiction is possible. Flexeril depresses the central nervous system, an effect some find desirable, which can lead to misuse.

An individual might abuse Flexeril in order to feel relaxed, mildly euphoric, or sedated. Flexeril produces a variety of anticholinergic effects in high doses, altering the activity of brain neurotransmitters. Chronic use of the drug can lead to physical dependence; a person that was simply taking a higher dose of Flexeril due to pain can become accustomed to the presence of the drug in the system and develop an addiction as a result.

Additionally, Flexeril users may experience mild withdrawal symptoms if the drug is used chronically in high doses. Signs that indicate someone may have a Flexeril addiction include:

Taking Flexeril after it’s no longer needed or for longer than prescribed. Needing more and more of the drug to elicit the same effects. Spending the majority of the day thinking about Flexeril: how to get more, the effects it produces, and when to use it. Constantly using Flexeril and being unable to stop. Faking symptoms to get Flexeril prescriptions. Sudden changes in physical appearance, hygiene, and behavior.

Another telltale sign of Flexeril addiction is abusing the medication in combination with another substance to produce a greater sense of euphoria. Alcohol is commonly abused alongside muscle relaxers like Flexeril because the substances amplify each others’ effects, causing the individual to experience a more intense sedation or high.

People might also use Flexeril as a way to come down from Stimulant drugs, such as Cocaine or Adderall, When people addicted to Flexeril attempt to stop taking it or reduce their doses they may start to experience withdrawal symptoms, although these are typically not severe. Flexeril withdrawal symptoms can include headache, nausea, fatigue, and cravings for the drug.

  • Most of us try to use home remedies to feel better, like taking over-the-counter medications, resting, stretching, or even getting help from a physical therapist, but there are times when you just need more.
  • Those times are when you are dealing with back muscle spasms or cramps caused by injury, muscle pain, fatigue, stress, and overuse in your neck or back.

  • It’s always best to consult with a pain management specialist to help diagnose the pain and provide proper treatment.

If it is a muscle spasm, home remedies, such as over-the-counter medicines like acetaminophen or ibuprofen, are the first line of defense to treat your pain. These are ideal because they reduce inflammation, which is the ultimate cause of the pain. If that fails, and the spasms are not resolving on their own with rest, icing, hydration, and proper nutrition, the second line of defense is for your pain management specialist to prescribe muscle relaxers.

When used safely and according to doctor’s orders, they can be very beneficial. Since muscle spasms are typically healed within two to three weeks, a doctor typically will only prescribe a muscle relaxant for acute rather than chronic pain.
