Yurelax is a medication containing cyclobenzaprine as the active ingredient. It works by loosening muscle contractions and thus, reducing any pain these may cause.

Cyclobenzaprine is neither an analgesic nor an anti-inflammatory, only a muscle relaxant.

Indications of Yurelax

Doctors usually prescribe this drug to relieve pain caused by muscular contractures associated with acute and painful musculoskeletal processes. However, it isn’t useful when the cause of acute pain is a lesion of the central nervous system.

Furthermore, this is one of the drugs your doctor may prescribe when you experience intense muscle pain that originates from any of the following:

  • Muscle contracture
  • Sprain
  • Torticollis
  • Muscle tension
  • Whiplash

There are discussions on the way it exerts its effect and on its efficacy compared to placebos. In fact, the results obtained affirm that Yurelax reduces the discomfort caused by acute muscular pain in the studies conducted with it.

The main advantage of this drug is that the person affected by the pain can go on with their lives as usual. It makes it easier to continue with the regular activities even if a person is undergoing rehabilitation sessions in the affected area.

Dosage of Yurelax

The most common dosage is one tablet a day unless the doctor deems it necessary and increases the dosage to two or more tablets.

A person taking Yurelax will experience its effects in less than an hour and these will last throughout the day. The drug comes in the form of extended-release capsules, which is why one tablet a day is usually enough.

Doctors don’t recommend exceeding three weeks of treatment, as Yurelax can be addictive. Also, a person who overdoses on this drug will experience symptoms like:

  • Seizures
  • Severe drowsiness
  • Rapid or irregular heartbeat
  • Shortness of breath
  • Hallucinations
  • Increased or decreased body temperature
  • Vomiting

Side effects of Yurelax

The side effects of Yurelax are usually mild and the most frequent ones are drowsiness, dizziness, fatigue, and dry mouth.

Rarely, this drug may cause other side effects such as constipation, allergic skin reactions, headaches, and vision and hearing disturbances.

In addition, it could occasionally cause serious side effects like:

  • Gastrointestinal disorders
  • Vascular and cardiac disorders
  • Renal alterations
  • Tremors, paresthesia, or convulsions at the nervous system level

The side effects of Yurelax are sometimes associated with states of agitation, nervousness, anxiety, confusion, or disorientation. Also, there may be weakness or depression and it could lead to sleep disturbances.


Don’t use this drug if you have a history of hypersensitivity or allergy to cyclobenzaprine, as well as if you often experience arrhythmias or have other cardiac disorders or hyperthyroidism. Also, there are no specific contraindications for this, but consult your doctor if you’re pregnant or might be.

Recommendations when taking Yurelax

As we mentioned above, Yurelax can make you really sleepy, so your doctor will probably recommend taking it at dinner time or before bedtime.

People who’ve been taking Yurelax for a short period of time can stop the medication without having to progressively reduce the dose. However, those who’ve been taking Yurelax for a longer period of time must consult a doctor who can tell them the best way to get off the drug.

There are other drug alternatives to this muscle relaxant that have similar effects — diazepam, etoricoxib, and metamizole. Always consult your doctor first before taking any of them though.


Finally, Yurelax has a great capacity to relax you and relieve the pain caused by muscle spasms. Thus, it can be effective in eliminating pain when properly prescribed in the right doses, and for the right amount of time.

However, keep in mind that it can also have bad side effects. Remember, don’t self-medicate, as it could bring serious health consequences
