Does Cyclobenzaprine have Aspirin in it? 

Does Cyclobenzaprine have Aspirin in it? 

No, Cyclobenzaprine does not contain Aspirin. These two are different medications which are used for different therapeutic purposes. 

Cyclobenzaprine is a prescription muscle relaxant, which can be used to control muscle spasms which are often triggered suddenly and uncontrollably. Aspirin, on the other hand, is an over-the-counter non-steroidal anti-inflammatory drug (NSAID). 

Both of these meds work differently and have entirely different side effects profiles. You can take Aspirin whenever you need it but don’t take Cyclobenzaprine if not prescribed by your healthcare provider.

Why is Cyclobenzaprine prescribed and how does it affect your body? 

Cyclobenzaprine is prescribed to control involuntary muscle spasms and the pain associated with them. The treatment of Cyclobenzaprine should not exceed a few weeks because this medication can affect your brain(1)

Cyclobenzaprine basically controls the movement of the skeletal muscle, without affecting the muscle directly. It does so by affecting the parts of the brain which control muscle contraction. 

This is the main reason why such muscle relaxants should not be used for a long period of time. Cyclobenzaprine is associated with some side effects, like every other medication. However, you may not find this medication problematic as far as you continue using it properly. 

Common side effects 

  • Nausea
  • Vomiting 
  • Dry mouth 
  • Constipation 
  • Bloating
  • Extreme fatigue
  • Acid reflux 
  • Weakness 

Serious and rare side effects 

  • An allergic reaction 
  • Swelling in different parts of the body 
  • Difficulty in breathing 
  • Unsteadiness
  • Severe dizziness
  • Difficulty in urination 
  • Severe depression 
  • Tinnitus 
  • Nightmares 
  • Pale colouration of skin and eyes 

Make sure you report to your healthcare provider if you start experiencing any of the unusual or rare side effects of Cyclobenzaprine. Not every medication works well for everyone. 

It’s best to discuss your side effects with your doctor and to determine whether or not it’s safe for you to continue using this medication. 

Why is Aspirin used and how does it affect your body? 

Aspirin is an OTC Non-steroidal anti-inflammatory drug which can be used for the management of pain, fever, and inflammation. Aspirin can also be used as a blood thinner in people who have coronary artery disease or those who are at high risk of cardiac problems(2).

Aspirin produces these effects by inhibiting the synthesis of Prostaglandins, which are important mediators of pain and inflammation. However, Prostaglandins also make up the protective lining around your stomach. 

This Prostaglandin inhibition is the main reason why Aspirin causes gastrointestinal side effects. 

Common side effects 

  • Nausea
  • Vomiting 
  • Abdominal pain
  • Acid reflux 
  • Flatulence 

Rare and serious side effects 

  • An allergic reaction or hypersensitivity 
  • Arrhythmia or abnormal heartbeat
  • Irregular breathing 
  • Tremors 
  • Bloody vomiting 
  • Loss of hearing
  • Black or tarry stools – indicating gastrointestinal bleeding
  • Ulceration 

Make sure you reach out to your healthcare provider if you’re experiencing any of the rare or serious side effects of Aspirin. If you feel extreme stomach pain or find your stools to be black in colour, stop the use of Aspirin right away and talk to your doctor. 

Can Cyclobenzaprine be taken with Aspirin?

Cyclobenzaprine can be taken with low-dose Aspirin, as low doses of Aspirin do not necessarily interact with Cyclobenzaprine. However, high doses can cause side effects. Cyclobenzaprine can also be taken with some other NSAIDs, like Diclofenac.

However, it’s best to discuss combining these medications with your doctor before you actually do it. People are different and can respond differently to medications. Some people may not do well on this combination because of some underlying factors. So, always discuss such things with your provider.
