How effective is opiates for fibromyalgia?

80% of fibromyalgia patients complain of being in pain always and the severity of fibromyalgia pain is decribed to be more painful than having multiple sclerosis. Usually, doctors prescribe opiates to fibromyalgia patients out of compassion for their predicament so that their pain can be alleviated.

Opiate can worsen fibromyalgia pain
However, studies have found that while being a potent painkiller for chronic pain, long term usage of the drug could adversely make pain worse. Opiates is found to increase sensitivity to other pain stimuli or lower pain threshold, a condition known as opioid-induced hyperalgesia. It remains unclear whether the hyperalgesia is caused by long term usage or withdrawal from the drug.

Chronic pain patients develop tolerance to opiates
As people tend to develop analgesic tolerance to the drug, patients have to depend on a higher dosage of the painkiller for pain relief after a certain period of time. Studies suggest that the analgesic effectiveness of the same dosage of opiates can be last up to eight weeks, however, little is known on the performance of the same dosage beyond the period of eight weeks.

It is also becoming more evident that some patients require faster dosage escalation and some attempt to get more prescriptions by visiting different clinics. Hence, although short term use of opiates appears effective in relieving pain in fibromyalgia, long term use of the drug can cause more concerning problems such as abuse, addiction and the two abovementioned factors.

Other side effects of using opiates every day

  • Opiates will no doubt help you to get relief from the pain, but when you consume it on a daily basis, you may end up being addicted to it.

  • Opiates can cause breathing disorders.

  • Irregularity in bowel movement is common. Constipation is a major side effect of consuming opiates.

  • The overdose of the medicine may trigger complications in your physical health, especially when you suffer from serious ailments like diabetes, kidney dysfunction, heart disease and so on.

  • Abuse or overdose of opiates can lead to respiratory failure and death.

  • Opiates are believed to cause psychological issues in patients such as unstable metal symptoms, suicidal tendencies.


In conclusion, it is better for opiates to be taken in low dosages and for a shorter period of time. Fibromyalgia patients should look to discontinue the use of opiates eventually.
