Methocarbamol is a muscle relaxant that can be helpful to people who are experiencing muscle spasms or pain because of an injury, disease, or disorder. However, if you have a medical condition that affects your blood pressure, there are a few effects of methocarbamol that you should be aware of. Learn more about how methocarbamol can affect your blood pressure.
What is Methocarbamol?
Methocarbamol is a prescription medication that’s used for its muscle relaxant capabilities. It’s in a class of drugs called carbamates, which all share a similar chemical structure. Methocarbamol is sold under the brand name Robaxin, and it’s been used in the United States since the 1950s. Methocarbamol is used as a short-term therapy for musculoskeletal pain.
As a muscle relaxant, it works to slow down the nervous system, particularly the impulses that cause muscle contractions. Injuries, especially to the spine, can cause muscle tightness and spasms. These symptoms can be painful or uncomfortable.
Methocarbamol offers a pain relief alternative to opioids for the treatment of muscular pain in certain cases. The drug is often taken by patients who are going through physical therapy to help alleviate muscle tightness and pain that would otherwise make therapy more difficult. Methocarbamol isn’t useful in the treatment of chronic diseases that might cause muscle pain or spasms like cerebral palsy.
How Methocarbamol Affects Blood Pressure
Methocarbamol has been reported to cause hypotension in some circumstances. Some drugs that depress the central nervous system can also affect the automatic functions of your nervous system. That means it may slow down your heart rate and blood pressure. In most cases, these effects are mild. They may be more dangerous if the drug is abused in high doses or mixed with alcohol. If you’re prone to low blood pressure, double-check with your doctor that the medication is safe to use. It may also increase adverse side effects if it’s mixed with alcohol, prescription depressants, or opioids.
Methocarbamol can interact with blood pressure medication Lisinopril. The interaction is considered to be moderate, but it can have some potentiating effects. Potentiation is when a drug interacts with another to increase its effects.
Lisinopril is designed to lower your blood pressure if you have hypertension. Since the interaction is moderate, your doctor may still prescribe both at once; however, you may experience lightheadedness, fainting, dizziness, and changes to your heart rate. If you experience persistent or severe side effects, let your doctor know immediately.
Other Side Effects
Methocarbamol can cause other side effects that you should be aware of if it’s been prescribed to you. The drug is well-tolerated, but if symptoms persist, or if they’re severe, you should speak to your doctor as soon as possible.
In addition to the following symptoms, if you experience more severe uncommon symptoms like fever, chills, changes in heart rate, seizures, or jaundice, speak to your doctor immediately.
More Common Symptoms May Include:
- Spinning sensations
- Memory issues
- Loss of balance or coordination
- Flushing of the skin
- Blurred or double vision
- Eye redness
