Usually, people won’t die from a cyclobenzaprine overdose. There are over 12,000 people in the U.S who will go to the emergency room looking to be treated for Flexeril overdose. A study showed that 209 people who overdosed on Flexeril on its own survived the ordeal. Mixing the drug with other substances, however, has shown to cause accidents leading to death. Eighteen VLD CBP-treated and 18 placebo-treated subjects were evaluated using last observation carried forward (LOCF) and compared using a paired t test for within-group change with a 2-sided p value (Table 3). In addition, the VLD CBP and placebo groups were compared using change from baseline at Week 8 using a 2-sample t test with a 2-sided p value (Table 3).

Interactions that can increase the effect of cyclobenzaprine

I thought I saw someone standing in my bedroom, and it looked like a child. I kept seeing bright flashes of light that were gone before I could even register that I had seen them. At that point, I needed it, and I slept for seven hours straight. I was still in a daze, and I didn’t take any more of the drug. I guess at that point, I really didn’t feel like I could.

The acute oral LD50 of FLEXERIL is approximately 338 and 425 mg/kg in mice and rats, respectively. If cyclobenzaprine is beingmisused, however, the person may continue to take the medication for much longer and may increase their dose too high, which could lead to dangerous side effects and overdose. A 2011, a double-blind randomized placebo-controlled study published by The Journal of Rheumatology found that the drug may also be useful in treating those with fibromyalgia sleep better. A 2016 drug used to deliver cyclobenzaprine into the body of fibromyalgia patients was recently halted during trials. Other drugs using cyclobenzaprine are also being tested to treat fibromyalgia, though. The current form of cyclobenzaprine is not approved by the FDA for the treatment of fibromyalgia.
