As is the case with any other medication, there may be some instances where methocarbamol interactions can occur. In such cases, use is not recommended or usage will have to be adjusted in order to prevent or reduce the risk of negative interactions occurring from other drugs, medical conditions, or even food and drink.
According to the FDA, drugs that may interact with methocarbamol include the following.
- Anticholinesterase agents
Please note that this list may not be complete, and other interactions with drugs not listed here may occur.
Methocarbamol and Tizanidine
Tizanidine (Zanaflex) and methocarbamol are both muscle relaxants. Both of these drugs have a sedative effect, so taking them together would likely exacerbate side effects such as sleepiness and poor concentration.
Methocarbamol and Tylenol
Methocarbamol is a muscle relaxant, and Tylenol (acetaminophen) is a pain reliever. There are no known interactions between these drugs. In some countries, like Canada, the two actually come combined in one medication for muscular pain relief.
Methocarbamol and Tramadol
Tramadol (ConZip, Ultram) is a narcotic pain reliever with a sedative effect. It’s not recommended that these two medications be taken together because they both depress the central nervous system. That may lead to respiratory problems and even coma.
Methocarbamol and Aleve
The primary ingredient in Aleve is naproxen, which is a nonsteroidal anti-inflammatory agent (NSAID). There is no known interaction between naproxen and methocarbamol.
Methocarbamol and Xanax
Xanax (alprazolam) is a benzodiazepine used to treat anxiety disorders. Taking methocarbamol and Xanax together could increase the side effects of either drug, including dizziness, drowsiness, and confusion.
Methocarbamol and Advil
Advil (ibuprofen) is a nonsteroidal anti-inflammatory agent. There are no known interactions between Advil and methocarbamol.
Methocarbamol and Lexapro
Lexapro (escitalopram) is an SSRI antidepressant. Taking it with methocarbamol will likely enhance the sedative side effects such as sleepiness, dizziness, and confusion.
Gabapentin (Neurontin) is an anticonvulsant medication and also used for nerve pain. Taking it with methocarbamol will probably enhance some of their common side effects like sleepiness and confusion.
Warfarin (Coumadin) is an anticoagulant or blood thinner. There is some evidence that taking methocarbamol with drugs that thin the blood may increase the risk of bleeding.
Diphenhydramine is an antihistamine, and like most, it can make you drowsy. Combining it with methocarbamol may intensify that effect.
Losartan (Cozaar) is medication to treat high blood pressure. There is no indication of interaction between losartan and methocarbamol. Some high blood pressure medications such as amlodipine or metoprolol can lead to an increase in side effects when taking with methocarbamol, though.
There is no indication of an interaction between methocarbamol and antibiotics. A prescribing physician should always be made aware of any medication a patient takes, however, when they are prescribing an antibiotic.
Xarelto (rivaroxaban) is an anticoagulant medication. Methocarbamol can increase the risk of bleeding with taken with anticoagulants.

Disease & Conditions Interactions
Sometimes certain medications can increase the risk of negative side effects for patients with certain diseases or other medical conditions. According to Prescriber’s Digital Reference, diseases and medical conditions that are known to interact with methocarbamol negatively include:
- There is a reduction of clearance of this drug in people with liver diseases such as cirrhosis

Other potential interactions include the following.
Methocarbamol and Weed
There is no indication of an interaction between methocarbamol and marijuana, or “weed.” Both drugs have a sedative nature, though, so it’s likely that weed will enhance some of the side effects of methocarbamol, such as sleepiness and lack of coordination.
