Fibromyalgia Medicines: How Much Do They Really Help?
12 Oct 2026
A new review of 151 trials in the BMJ Medicine found that fibromyalgia medicines may give small benefits for some people, but the evidence is low certainty and no drug clearly beat the bar for a clinically important change in pain [1]. Exercise remains the best-supported treatment, so medicines are best seen as one part of a wider plan [2].
Fibromyalgia Medicines at a glance
- Review: 151 randomised trials with 32,592 adults, published in BMJ Medicine in October 2026 [1].
- Drugs that may help a little: sodium oxybate, SNRIs and other noradrenaline-acting drugs, gabapentinoids, tricyclics and SSRIs for some outcomes [1].
- No drug showed average effects on pain, physical health or mental health that met the threshold for clinical importance [1].
- Serious side effects and dropouts were not higher with the drugs than with placebo or usual care [1].
- Exercise is described as the only intervention with a strong recommendation, with aquatic exercise and resistance training doing well [2].
What did the new fibromyalgia review look at?
Canadian and Swiss researchers searched six databases for randomised trials of drug treatments in adults with fibromyalgia. They found 151 trials with 32,592 participants. The drugs included antidepressants, gabapentinoids such as pregabalin, muscle relaxants, sodium oxybate and some supplements such as vitamin D and omega-3 [1].
They compared drugs with placebo or usual care using a network meta-analysis, which lets researchers compare treatments even when they were not tested head to head [1].
Which medicines helped, and by how much?
The authors found low-certainty evidence that sodium oxybate, drugs that act on noradrenaline, SNRIs (such as duloxetine) and gabapentinoids may increase the chance of a patient reporting meaningful improvement. That worked out at roughly 105 to 283 more people per 1,000 improving than with placebo or usual care [1].
On the Fibromyalgia Impact Questionnaire, sodium oxybate and SSRIs may reduce overall symptoms. Tricyclic antidepressants, sodium oxybate and gabapentinoids may improve sleep quality [1].
When they looked at pain alone, however, no drug's average effect reached the level considered clinically important. Some drugs did bring a 30% or greater pain reduction to a useful extra share of people: 111 to 202 more per 1,000 for sodium oxybate, noradrenaline-acting drugs, SNRIs and cyclobenzaprine [1].
Is duloxetine worth trying?
A separate meta-analysis of 11 trials (3,432 people) found duloxetine was more effective than placebo at every dose studied, and suggested the dose should be tailored to the person [3]. That fits with the BMJ Medicine finding that SNRIs may help some people. It does not mean everyone will respond. Antidepressants can cause side effects, so a doctor needs to review you.
| Drug group | Possible benefit | Certainty |
|---|---|---|
| SNRIs, noradrenaline-acting drugs | Meaningful improvement and more people with 30% pain reduction | Low |
| Gabapentinoids | Meaningful improvement and better sleep | Low |
| Sodium oxybate | Improvement, lower symptom score, better sleep | Low |
| Tricyclics | Better sleep quality | Low |
| SSRIs | Lower overall symptom score | Low |
What the BMJ Medicine review found for drug groups in fibromyalgia [1].
Why is exercise still recommended first?
The drug effects above are small, so exercise deserves a serious look. A network meta-analysis of 51 trials in women with fibromyalgia describes therapeutic exercise as the only intervention with a strong recommendation. It found aquatic exercise gave the best short-term pain relief, and resistance training the best long-term relief, with moderate certainty [2].
If exercise makes you sore at first, tell your physiotherapist. They can start with short, gentle sessions and build up slowly.
What does a sensible plan look like?
- Confirm the diagnosis. Fibromyalgia is diagnosed from your history and exam, and other conditions such as thyroid disease or inflammatory arthritis should be ruled out.
- Start graded exercise with guidance, ideally in water if you can reach a pool.
- Work on sleep and stress, since poor sleep can make pain feel worse. CBT can help with both.
- If you try a medicine, agree a trial period with your doctor, and stop if there is no real benefit.
- Avoid stacking several drugs at once without a plan, because side effects can add up.

Frequently asked questions
Is there a cure for fibromyalgia?
No. Treatment aims to reduce pain and improve sleep and daily function. Reviews show small benefits from several drugs and larger benefits from regular exercise [1,2].
Which fibromyalgia medicine works best?
No drug stood clearly above the rest. SNRIs, gabapentinoids and sodium oxybate showed possible benefit, but with low-certainty evidence [1].
Are fibromyalgia drugs safe?
In the review, no drug increased serious adverse events or treatment dropouts compared with placebo or usual care [1]. Individual side effects still vary, so review with your doctor.
Which exercise is best for fibromyalgia pain?
Aquatic exercise was best for short-term relief and resistance training for long-term relief in one analysis, with moderate certainty [2].
Can fibromyalgia be treated without medicines?
Many people manage mainly with exercise, sleep care and psychological support. Whether you also need a drug is something to decide with your doctor.
