Flexeril, the brand name for cyclobenzaprine, is a muscle relaxant prescribed for mild to moderate muscle pain relief. It is prescribed in different doses depending on the type of muscle pain and how severe it is.

How much Flexeril can I take in one dose?

For more severe muscle pain the maximum dose is 10mg three times a day. Flexeril should not be taken or prescribed for more than 2 to 3 weeks.[1]

Cyclobenzaprine, commonly prescribed under the brand names Flexeril and Amrix, are a muscle-relaxing drug used to mild to moderate muscular and musculoskeletal pain. 

For mild muscle pain and spasms, the standard dose prescribed is 5mg to be taken a maximum of 3 times a day.[1]

Taking Flexeril in the recommended dosage and for the right length of time should pose little to no risk of dependence or addiction forming. Abusing the drug in higher doses or combining it with other central nervous system depressants like benzodiazepines increases the risk of addiction as well as the potential for overdose.

Can I take 2 Cyclobenzaprine 10mg at the same time?

While the maximum dose of Cyclobenzaprine is 3 X 10mg daily, it is not advised to take this date at once, or even 2 x 10mg in one dose.

Overtaking Flexeril, even in the daily recommended dose, can lead to uncomfortable side effects such as dry mouth, headaches, drowsiness, fatigue, and stomach pain.

It also increases the risk of abusing the substance, which may lead to dependence forming. 

Flexeril overdose

Another potential side effect from Flexeril abuse is cyclobenzaprine overdose, especially if taken in conjunction with other substances such as other CNS depressants like alcohol. Flexeril causes the body to become relaxed and abusing the substance in high doses can lead to cardiac arrest, low blood pressure, heart attack, and seizures. 

Signs someone is having a Flexeril overdose include:

  • Vomiting
  • Slurred speech
  • Rapid heartbeat
  • Hallucinations
  • Difficulty breathing
