Frequently Asked Questions about Metaxalone

1. Is Metaxalone a narcotic?

Metaxalone isn't a narcotic but a centrally acting skeletal muscle relaxant that has side effects related to the central nervous system, such as dizziness, drowsiness, and nervousness. The medicine should be taken as per the doctors' advice, and if any consequences arise, they must be immediately reported by the patient. The withdrawal symptoms can be life-threatening in some patients.

2. Is Metaxalone addictive?

Metaxalone 800 mg dose is not a controlled substance and cannot cause dependence when taken within prescribed limits. Since the drug acts centrally on the brain and spinal cord, there is a sense of relief and depression in the central nervous system. The drug has a higher potential for substance abuse and hence to be taken cautiously.

3. Does Metaxalone raise blood pressure?

Metaxalone is known to be one of the most tolerant skeletal muscle relaxants with minor side effects. Unlike other skeletal muscle relaxants, the drug does not increase blood pressure. Certain medications such as cyclobenzaprine can block the effect of guanethidine, a blood pressure-lowering drug, subsequently increasing the patient's blood pressure.

4. Is Metaxalone a controlled substance?

Metaxalone 800 mg is not a controlled drug under the Controlled Substances Act (CSA) and possesses no pregnancy risk. If the drug is used for long-term treatment, it can cause hepatotoxicity and renal dysfunction. However, the drug has the lowest sedation potential and minimal side effects that can wane off on its own.

5. Is Metaxalone an anti-inflammatory?

Metaxalone is a centrally acting muscle relaxant that directly affects the muscle tissue, blocking the nerve impulses and acting as a pain reliever in acute, traumatic, and inflammatory musculoskeletal disorders. It has outperformed anti-inflammatory drugs such as NSAIDs and Ibuprofen in treating inflammation and acute muscle pain along with proper rest and physical exercise.

6. Does Metaxalone cause allergic reaction?

The chance of getting a severe allergic reaction is scarce, and most of the side effects are minimal and do not require any medical attention. However, suppose you notice any severe signs such as rashes, hives, inflammatory swelling with allergy and symptoms of breathlessness, irregular heartbeat, severe dizziness, or any other. In that case, you should immediately report to the concerned health facility and seek medical help.

7. Is Metaxalone a painkiller?

Metaxalone has an exact unknown mechanism of action, but since the drug acts on the brain and spinal cord, it blocks the nerve impulses from the central nervous system to reach the muscle tissue. It is known to cause a sedative effect by preventing the pain signals from reaching the brain. The drug must be taken along with rest, physical therapy, and other treatment for best results.

8. Does Metaxalone make you sleepy?

The most common side effects of metaxalone include drowsiness, dizziness, restlessness, and confusion. The drug is known to cause a sedative effect because of its centrally acting mechanism of action and depression of the central nervous system. However, the outcome may be short-lived, but if required, a doctor's advice is recommended.

9. Is Metaxalone a strong muscle relaxer?

Metaxalone is a moderate muscle relaxant with minimal side effects and is best tolerated in the category of muscle relaxants. The drug acts by blocking nerve impulses and causing relief from muscle pain, acute painful spasms, and muscle rigidity. The drug is known to improve muscle stiffness and movement.

10. Does Metaxalone help with anxiety?

Metaxalone can help with anxiety by relaxing the central nervous system and consequent side effects of dizziness, drowsiness, and sedation. The drug is a short-term therapy. If you experience any harmful side effects such as restlessness, fast heartbeat, fever, sweating, or any other unusual condition, it must be reported immediately.
