Medicines for Carpal tunnel syndrome

Compression of the median nerve at the wrist, causing tingling, numbness and pain in the thumb and fingers that is often worse at night — frequently helped by a wrist splint.

Quick answer

What is Carpal tunnel syndrome?

Carpal tunnel syndrome happens when the median nerve, which runs through a narrow channel at the front of the wrist called the carpal tunnel, becomes squeezed. This causes tingling, numbness, pins and needles and pain in the thumb, index, middle and part of the ring fingers, and the symptoms are often worse at night, sometimes waking people from sleep.

  • How it is treated: Treatment depends on how severe and persistent the symptoms are.
  • Self-care: Wearing a wrist splint, particularly at night, keeps the wrist in a position that takes pressure off the nerve and often eases symptoms.
  • When to seek help: See a GP if tingling, numbness or pain in the hand is persistent, disturbs your sleep, or affects your grip and daily tasks, so it can be assessed and the right treatment arranged.

What it is

Carpal tunnel syndrome happens when the median nerve, which runs through a narrow channel at the front of the wrist called the carpal tunnel, becomes squeezed. This causes tingling, numbness, pins and needles and pain in the thumb, index, middle and part of the ring fingers, and the symptoms are often worse at night, sometimes waking people from sleep. The hand may feel clumsy or weak, and in time the grip can weaken. It is more likely during pregnancy and in people with an underactive thyroid (hypothyroidism) or diabetes, and is associated with repetitive or forceful use of the hands and wrists. Symptoms can be mild and intermittent or steadily more troublesome, and they sometimes ease on their own — for example after pregnancy.

How it is treated

Treatment depends on how severe and persistent the symptoms are. For milder cases, a wrist splint — especially worn at night to keep the wrist in a neutral position — often eases the tingling and pain, and adjusting activities that provoke symptoms helps. Where there is an underlying contributor such as an underactive thyroid or diabetes, managing that condition is part of the picture. If symptoms persist, a corticosteroid injection into the carpal tunnel can reduce swelling around the nerve and bring relief, sometimes lasting. Anti-inflammatory painkillers may be used to ease symptoms, though they do not address the compression itself. When symptoms are severe, are not helped by these measures, or there are signs the nerve is being damaged, surgery to release the carpal tunnel (carpal tunnel decompression) is the definitive treatment and is generally very effective.

Symptoms that can point to Carpal tunnel syndrome

Carpal tunnel syndrome 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

Wearing a wrist splint, particularly at night, keeps the wrist in a position that takes pressure off the nerve and often eases symptoms. Adjusting tasks that involve repetitive or forceful wrist movements, taking regular breaks, and setting up workstations so the wrists stay neutral can all help. If a contributing condition such as an underactive thyroid or diabetes is present, keeping it well managed supports improvement.

When to get help

When to see a doctor

See a GP if tingling, numbness or pain in the hand is persistent, disturbs your sleep, or affects your grip and daily tasks, so it can be assessed and the right treatment arranged. Get prompt review if the numbness becomes constant rather than coming and going, if the hand is becoming weak, or if you notice wasting (loss of muscle bulk) at the base of the thumb — these can indicate the nerve is being damaged and may mean surgery is needed sooner rather than later.

Answers

Carpal tunnel syndrome: frequently asked questions

What medicines are used for carpal tunnel syndrome?

Medicines play a supporting role alongside a wrist splint. A corticosteroid injection into the carpal tunnel can reduce swelling around the nerve and relieve symptoms, sometimes for a sustained period. Anti-inflammatory painkillers may ease the discomfort, though they do not relieve the underlying compression. When symptoms are severe or persistent, surgery to release the carpal tunnel is the definitive treatment.

Does a wrist splint help carpal tunnel syndrome?

Yes — a wrist splint is a mainstay of treatment for milder symptoms. Worn especially at night, it keeps the wrist in a neutral position that takes pressure off the median nerve and often eases the tingling, numbness and pain, including the night-time symptoms that commonly disturb sleep. It is a simple, non-invasive measure that suits many people as a first step.

When is surgery needed for carpal tunnel syndrome?

Surgery to release the carpal tunnel (carpal tunnel decompression) is considered when symptoms are severe, are not helped by a splint, injection or activity changes, or when there are signs the nerve is being damaged — such as constant numbness or wasting of the muscle at the base of the thumb. It is generally very effective, and these warning signs mean it should not be delayed.

Why is carpal tunnel syndrome worse at night?

Many people find symptoms are worse at night and may be woken by tingling or numbness. This is partly to do with wrist position during sleep and fluid shifts that increase pressure within the carpal tunnel. A wrist splint worn overnight keeps the wrist in a neutral position and often reduces these night-time symptoms.
