What You'll Learn
Flexeril (Cyclobenzaprine) is a muscle relaxant
Flexeril (Cyclobenzaprine) is a prescription medication that helps to relax muscles and reduce muscle stiffness. It is a muscle relaxant that is used to treat muscle spasms and relieve pain, stiffness, and discomfort caused by strains, sprains, or injuries. It is important to note that Flexeril should be used as an adjunct to rest, exercise, or physical therapy and should not replace them.
Flexeril works by calming down muscle cramps in specific areas of the body without affecting overall muscle function. It helps reduce excessive muscle activity, thereby lessening muscle tension and providing relief from pain and stiffness associated with muscle spasms. The recommended dosage of Flexeril is typically 5 mg, taken three times daily as needed. However, it is crucial to consult a doctor to determine the appropriate dosage and duration of treatment, as Flexeril is usually prescribed for short periods of up to two to three weeks.
While Flexeril can be effective in managing muscle spasms, it may also cause side effects. Common side effects include drowsiness, dry mouth, headaches, upset stomach, and trouble focusing. It is important to be cautious when taking Flexeril with other substances that cause drowsiness, such as alcohol, benzodiazepines, or opioids, as it can lead to serious side effects. Additionally, older adults and those taking doses above 5 mg might experience difficulty focusing.
In rare cases, Flexeril has been associated with more severe side effects, including heart rhythm changes and serotonin syndrome. Serotonin syndrome occurs when there is an excess of serotonin in the body, which can be life-threatening. Symptoms of serotonin syndrome include anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, and diarrhoea. If you experience any of these symptoms, it is crucial to seek immediate medical attention.
It is important to consult your healthcare provider before taking Flexeril to ensure it is safe for you and to discuss any potential side effects or interactions with other medications.

It treats muscle spasms and reduces muscle stiffness
Cyclobenzaprine, commonly known by the brand name Flexeril, is a medication that treats muscle spasms and reduces muscle stiffness. It belongs to a group of medications called muscle relaxants. Cyclobenzaprine works by relaxing the muscles, which helps to reduce muscle stiffness and relieve muscle spasms. It is often used to treat muscle spasms resulting from injuries or conditions that cause muscle or joint pain.
Cyclobenzaprine is typically used as an adjunct to rest and physical therapy for the relief of muscle spasms associated with acute, painful musculoskeletal conditions. It helps to calm down muscle cramps in specific areas of the body without affecting overall muscle function. By reducing excessive muscle activity, cyclobenzaprine lessens muscle tension and relieves associated pain and stiffness. It is important to note that cyclobenzaprine does not replace the need for rest, exercise, or physical therapy recommended by a doctor.
The recommended dose of Flexeril is typically 5 mg taken three times a day. However, it is important to follow the instructions provided by your healthcare provider, as the dosage may vary depending on individual needs. Flexeril is usually taken for short periods of up to two to three weeks, as there is inadequate evidence of its effectiveness for prolonged use.
While Flexeril can be effective in treating muscle spasms and stiffness, it may also cause side effects. Common side effects include drowsiness, dry mouth, headaches, upset stomach, and trouble focusing. In rare cases, more serious side effects like heart rhythm changes and serotonin syndrome have been reported. It is important to consult a healthcare provider if you experience any side effects or have any concerns about taking Flexeril.

It can cause drowsiness, dizziness and dry mouth
Cyclobenzaprine, commonly known by its brand name Flexeril, is a prescription medication used to treat muscle spasms. It is a muscle relaxant that helps to reduce muscle stiffness and relieve pain caused by strains, sprains, or injuries. While it is an effective treatment option, it can cause some side effects, the most common of which is drowsiness.
Drowsiness is a frequent adverse reaction to Flexeril, with the 10 mg dose more likely to cause drowsiness than the lower 5 mg and 7.5 mg doses. This side effect can be exacerbated when Flexeril is taken with other substances that cause drowsiness, such as alcohol, benzodiazepines, opioids, or other medications that affect the central nervous system (CNS). Therefore, it is important for patients to inform their care team about all the medications they are taking to avoid any harmful interactions.
Another common side effect of Flexeril is dizziness. In clinical trials, dizziness was observed more frequently in patients treated with diazepam, a similar medication, compared to those treated with Flexeril. However, it is still a possible side effect, and patients experiencing dizziness should report it to their care team as soon as possible.
Dry mouth is another frequently reported side effect of Flexeril. Chewing sugarless gum or sucking on hard candy, and drinking plenty of water may help alleviate this symptom. If the problem persists or becomes severe, patients should contact their care team for further advice.
While these side effects may occur, it is important to note that they often do not require medical attention and may diminish as the body adjusts to the medication. However, patients should consult their healthcare professionals if these side effects are bothersome or persist.

It may increase the risk of certain side effects when taken with other medicines
Cyclobenzaprine, commonly known as Flexeril, is a medication that helps relax muscles and reduce muscle stiffness. It is used to treat muscle spasms and relieve pain, stiffness, and discomfort caused by strains, sprains, or injuries. While it is an effective treatment option, it can sometimes cause side effects, especially when taken with certain other medications.
When taken with other medicines, cyclobenzaprine may increase the risk of specific side effects. It is important to consult your doctor or healthcare provider about any other medications you are currently taking to ensure safe usage. Here are some of the potential interactions and increased side effects:
- Central Nervous System (CNS) Depressants: Cyclobenzaprine may interact with other CNS depressants, including alcohol, antihistamines, sedatives, tranquilizers, sleeping medications, prescription pain medicines, narcotics, barbiturates, anesthetics, and certain anti-seizure medications. This interaction can enhance the depressant effects, leading to increased drowsiness and potential respiratory depression.
- Tricyclic Antidepressants: Cyclobenzaprine is closely related to tricyclic antidepressants. When taken together, there may be an increased risk of central nervous system reactions and other side effects associated with these antidepressants. Additionally, tricyclic antidepressants may enhance the seizure risk in patients also taking tramadol.
- Medications Affecting Serotonin Levels: When combined with other medicines that affect serotonin levels, cyclobenzaprine can increase the risk of serotonin syndrome, a serious and potentially life-threatening condition. Symptoms of serotonin syndrome include anxiety, restlessness, fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, and hallucinations.
- Dizziness and Sleepiness-Inducing Medications: Taking cyclobenzaprine with other substances that cause dizziness and sleepiness, such as benzodiazepines, opioids, prescription pain medicines, sleep medicines, and anxiety medications, can lead to enhanced side effects related to dizziness and drowsiness.
It is important to note that in some cases, the use of cyclobenzaprine with certain medications may be unavoidable or even the best treatment option. Your doctor may adjust the dosage or provide special instructions to minimise the risk of increased side effects. Always consult your healthcare provider before starting or stopping any medication to ensure your safety and well-being.

It should only be used for 2 to 3 weeks at a time
Cyclobenzaprine, commonly known by its brand name Flexeril, is a prescription medication used to treat muscle spasms. It is a muscle relaxant that works by calming down muscle cramps and reducing muscle stiffness. It is typically used to relieve pain, stiffness, and discomfort caused by strains, sprains, or injuries to the muscles.
While Flexeril can be effective in managing muscle spasms, it is recommended for short-term use only. Specifically, it should be taken for no more than two to three weeks at a time. This recommendation is based on a few important factors:
- Effectiveness for prolonged use: There is inadequate evidence to support the effectiveness of Flexeril for long-term use. Muscle spasms associated with acute, painful musculoskeletal conditions typically last for a short duration, and specific therapy for longer periods is usually not necessary.
- Side effects: Flexeril can cause various side effects, even when used for a short period. Common side effects include drowsiness, dry mouth, headaches, upset stomach, and trouble focusing. In rare cases, it can also lead to heart rhythm changes and serotonin syndrome, a serious condition caused by increased serotonin levels in the body.
- Interaction with other substances: Flexeril may interact with other substances, increasing the risk of side effects. It can enhance the effects of alcohol, barbiturates, central nervous system (CNS) depressants, and certain medications like antidepressants, bladder or urinary medications, and irritable bowel medications. Taking Flexeril with other substances that cause drowsiness, such as prescription pain medicines, sleep medicines, or opioids, can lead to serious side effects.
- Dependence and withdrawal: If you have been taking Flexeril for an extended period, stopping it abruptly can cause withdrawal symptoms like nausea, headache, fatigue, and a general feeling of being unwell. Therefore, it is essential to consult a healthcare provider before discontinuing the medication.
In conclusion, while Flexeril can be a helpful short-term solution for managing muscle spasms, it is crucial to adhere to the recommended duration of two to three weeks to minimize potential side effects and ensure safe use in conjunction with other substances. For long-term management of muscle spasms, it is advisable to consult a healthcare professional for alternative treatments or therapeutic approaches.
