Medicines for Fibromyalgia
A long-term condition causing widespread body pain, marked fatigue and poor sleep, where the most effective care is mainly non-drug, with medicines playing only a limited, supportive role for some people.

Quick answer
What is Fibromyalgia?
Fibromyalgia is a long-term condition characterised by widespread pain felt across many parts of the body, usually alongside profound fatigue, unrefreshing sleep and difficulties with concentration and memory often described as "fibro fog". People may also have headaches, low mood or anxiety, and heightened sensitivity to pain, touch, light or noise.
- How it is treated: The foundation of managing fibromyalgia is non-drug treatment, and this is where most of the benefit comes from.
- Self-care: Gentle, gradually increasing exercise such as walking, swimming or stretching, together with good sleep routines, pacing activity to avoid overdoing things on good days, and stress-management or relaxation techniques, form the cornerstone of managing fibromyalgia and tend to help more than any tablet.
- When to seek help: See a GP if you have widespread pain with persistent fatigue and poor sleep so the pattern can be assessed and other conditions ruled out, and for support in setting up an exercise, sleep and self-management plan.
What it is
Fibromyalgia is a long-term condition characterised by widespread pain felt across many parts of the body, usually alongside profound fatigue, unrefreshing sleep and difficulties with concentration and memory often described as "fibro fog". People may also have headaches, low mood or anxiety, and heightened sensitivity to pain, touch, light or noise. It is understood as a change in the way the nervous system processes pain signals, so that the system becomes more sensitive — the pain is genuine even though the joints and muscles are not damaged. There is no blood test or scan that confirms fibromyalgia; the diagnosis is made from the pattern of symptoms and by sensibly ruling out other conditions that can mimic it. Symptoms tend to come and go in flares, often worsened by stress, poor sleep or overdoing activity, and the condition affects daily life in different ways for different people. Although it is not curable, it is manageable, and understanding it well is a big part of living with it.
How it is treated
The foundation of managing fibromyalgia is non-drug treatment, and this is where most of the benefit comes from. A graded, gradually built-up exercise programme — starting gently and increasing slowly — is one of the most helpful approaches, together with good sleep habits, pacing activity to avoid the boom-and-bust cycle of overdoing things and then crashing, and psychological approaches such as cognitive behavioural therapy to help with pain, mood and coping. Education about the condition and realistic expectations matter a great deal. Medicines have only a limited, adjunct role and do not work for everyone: certain medicines used for nerve-type pain — a gabapentinoid, the SNRI duloxetine, or a low dose of the tricyclic amitriptyline — can ease pain or improve sleep in some people, and are tried and reviewed to see whether they genuinely help. Ordinary painkillers and, in particular, opioids are not recommended for fibromyalgia, as they tend not to help and carry real risks. The overall aim is to improve function and quality of life and to build self-management skills, rather than to chase complete freedom from pain.

Symptoms that can point to Fibromyalgia
Fibromyalgia can be one cause of these symptoms. Each guide explains the other possible causes and the red-flag warning signs that mean you should get urgent help:
Beyond medication
Lifestyle and self-care
Gentle, gradually increasing exercise such as walking, swimming or stretching, together with good sleep routines, pacing activity to avoid overdoing things on good days, and stress-management or relaxation techniques, form the cornerstone of managing fibromyalgia and tend to help more than any tablet.
When to get help
When to see a doctor
See a GP if you have widespread pain with persistent fatigue and poor sleep so the pattern can be assessed and other conditions ruled out, and for support in setting up an exercise, sleep and self-management plan. Seek prompt medical advice if you develop new or different symptoms that do not fit fibromyalgia — such as joint swelling, marked weakness, unexplained weight loss, fever, or new numbness — as these may point to another condition that needs investigating. If low mood becomes severe or you have thoughts of harming yourself, seek help urgently.

Answers
Fibromyalgia: frequently asked questions
What medicines are used for fibromyalgia?
Medicines play only a limited, supportive role, and the main treatment is non-drug. For some people, certain medicines used for nerve-type pain can ease symptoms: a gabapentinoid, the SNRI duloxetine, or a low dose of the tricyclic amitriptyline, often used to help pain and sleep. They are tried and reviewed to see whether they genuinely help. Importantly, ordinary painkillers and opioids are not recommended for fibromyalgia, as they tend not to help and carry real risks.
Why is there no test for fibromyalgia?
Fibromyalgia is not caused by damage or inflammation that shows up on a blood test or scan; it relates to the way the nervous system processes pain, which current tests cannot measure. So the diagnosis is made by recognising the typical pattern of widespread pain, fatigue and poor sleep, and by sensibly checking for other conditions that can cause similar symptoms. A normal set of tests does not mean the pain is not real — it is.
Does exercise really help fibromyalgia?
Yes — gradually built-up exercise is one of the most effective parts of managing fibromyalgia, even though it can feel counter-intuitive when you are sore and tired. The key is to start very gently and increase slowly, avoiding doing too much on a good day and then crashing. Over time, regular gentle activity such as walking, swimming or stretching tends to improve pain, energy, sleep and overall function.
Will fibromyalgia get better?
Fibromyalgia is a long-term condition that is not currently curable, but it is manageable and symptoms often vary over time, with flares and better spells. Many people improve their day-to-day life considerably with a combination of graded exercise, better sleep, pacing, psychological approaches and, for some, supportive medicines. Setting realistic expectations — aiming to improve function and quality of life rather than to remove pain entirely — is an important part of living well with it.
