Summary
- Trigeminal neuralgia (TN) is a rare condition where you can feel sudden, severe pain on your face. Even the things you do everyday like talking, eating, brushing your teeth, or washing your face can trigger the intense pain that feels like an electric shock.
- In the UK, Botox (botulinum toxin A) is not officially approved to treat trigeminal neuralgia. However, some specialists may recommend it to be used off-label in times where the standard treatments have not provided you with enough relief. Early research suggests that Botox may help reduce both the severity of pain as well as the number of painful attacks by 50% or more in some people.
- Botox injections are less invasive than surgery. It is usually performed in an outpatient clinic. However, there is currently no standard dose or injection technique for treating trigeminal neuralgia. So your doctor will tailor your treatment based on your needs.
- In the UK, the patient is usually given medications such as carbamazepine or oxcarbazepine as their first treatments. But, if these medicines don’t work well on you or give troublesome side effects, your doctor may refer you to a facial pain or neurology specialist to give you other options, including Botox.
- Before you decide on getting your Botox treatment, talk to your specialist about the possible benefits, risks, costs, whether it’s available through the NHS or private clinics, and what other treatments may be suitable for you.
Key Takeaway
If you are dealing with trigeminal neuralgia, Botox may offer pain relief, especially when standard treatments are no longer effective. Although the early results are really good, it is still considered an off-label treatment in the UK. For this reason, your treatment should only be carried out by an experienced specialist after a full assessment of your condition.
Understanding Trigeminal Neuralgia
What is Trigeminal Neuralgia?
Trigeminal neuralgia (TN) is a long-term condition that affects your trigeminal nerve. It is the nerve responsible for carrying feelings from your face to your brain. When this nerve becomes irritated or damaged, it can cause sudden bursts of severe pain in your face.
Many people describe the pain as:
- Electric shock-like
- Sharp and stabbing
- Burning or shooting
- Extremely intense (even though it usually lasts only a few seconds or minutes.
The pain comes and goes throughout the day, with some people experiencing repeated attacks. Even though each episode is short, the pain it gives can be severe enough to affect the patient’s everyday life.
Simple daily activities that can trigger your attack:
- Talking
- Smiling
- Eating or drinking
- Brushing your teeth
- Washing your face
- Applying make-up
- Shaving
- Feeling a cold breeze on your face
Because the pain from this condition is really unpredictable, many people begin to worry about their everyday activities. This can affect their sleep, eating habits, work, and the overall quality of their life.
Symptoms and Causes
The main symptoms you may have from trigeminal neuralgia is sudden, severe pain on one side of your face. The pain usually follows the path of the trigeminal nerve and may affect your cheek, jaw, teeth, lips, or around your eye.
Common symptoms that you may experience include:
- Sudden, sharp or stubbing facial pain
- Repeated attacks throughout the day
- Pain triggered by light touch or your everyday activities
- Pain-free period between the attacks
- Increased sensitivity on one side of your face
In most cases, trigeminal neuralgia is caused by a blood vessel pressing against your trigeminal nerve. Over time, this pressure removes the protective coating of your nerves, causing the pain signals to be sent to your brain even when there is really little or no reason for pain.
Other possible causes include:
- Multiple sclerosis (MS), which can damage your nerve covering
- A tumour pressing on your nerve
- Previous injury on your face
- Rare complications from your surgery
- No identifiable cause (known as idiopathic trigeminal neuralgia)
To diagnose trigeminal neuralgia, your doctor will ask about your symptoms, examine your nervous system, and may request an MRI scan. This will help confirm your diagnosis and rule out other conditions that can give you similar facial pain.

Botox as a Treatment Option
How Botox Relieve The Pain
Most people think of Botox as a treatment for wrinkles, but it is also used to treat several medical conditions.
If you have trigeminal neuralgia, Botox will not be used to change your appearance. Instead, it will be used to help calm your overactive nerves that are sending pain signals to your brain.
Many experts believe that Botox may help by:
- Reducing the release of chemicals that triggers your pain
- Calming the irritation around the affected nerve
- Blocking some pain signals before they reach your brain
- Making some of your sensitive trigger areas less likely to cause an attack
As a result, some people who use Botox experience fewer attacks, less severe pain, or both.
Unlike those pain-relieving tablets that work throughout your body, Botox is injected directly into the areas where your pain starts. This allows the treatment to target specific parts of your face.
Is Botox Good for Trigeminal Neuralgia?
For some people, Botox may be a good option. But it does not work for everyone.
So far, the research has shown promising results, especially for people who:
- Have not had enough pain relief from their medication
- Experience unpleasant side effects from their medication
- Are not suitable candidates for the surgery
- Want to delay their surgery if possible
Botox is usually used alongside other treatments, but your doctor may not recommend it as a replacement for standard medicines.
Some of the possible benefits you can get may include:
- You may have fewer painful attacks
- The facial pain you feel can be less intense
- The medication you are taking may be reduced
- The treatment is minimally invasive with no surgery
- You may repeat your treatments every few months if it continues to help you
However, you should keep in mind that Botox is not licensed in the UK to treat trigeminal neuralgia, so it is used off-label. Some people may experience significant pain relief, while others just get a little to no improvement.
Botox Administration
Who Can Give Botox for Trigeminal Neuralgia
Botox for trigeminal neuralgia is a specialised treatment. So, you should only get the treatment from a healthcare professional with experience in treating facial pain.
This may include:
- Consultant neurologists
- Pain medicine specialists
- Facial pain specialists
- Neurosurgeons who treat chronic pain
- Specialist clinicians who are trained in therapeutic Botox injections
You need to see your GP first, they can refer you to a trusted neurologist or a specialist facial pain clinic if Botox is suitable for you.
Procedure for Botox Injections
Botox injections are usually given in an outpatient clinic, so you can go home the same day right after your treatment.
Before the procedure, your specialist will:
- Ask about your symptoms and pain triggers.
- Review any treatments that you have already tried
- Explain about the possible benefits and risks
- Decide where your injection should be placed
During your treatment:
- Your skin is cleaned.
- You will be given several small Botox injections into specific areas of your face.
- The number of the injections to be given depends on where your pain occurs.
- It will take about 15 to 30 minutes to complete your treatment.
You may be given a numbing cream if needed to make you comfortable during the process.
You may notice pain relief within 1 to 4 weeks because Botox does not work right away. The effects usually last 3 to 6 months and you may need another treatment if it really helps manage your condition.
Efficacy and Evidence
Does Botox Work for Trigeminal Neuralgia?
Research suggests that Botox can help many people with trigeminal neuralgia, but it does not work for everyone.
Studies have shown that Botox may:
- Reduce the intensity of your facial pain
- Decrease how often your pain attacks happen
- Improve the quality of your life
- It may help you to rely less on pain medication
Some studies found that around 7 out of 10 people experienced at least 650% reduction in their pain after having their Botox treatment.
Botox is not a cure, but it may be a useful treatment option as part of your personalised care plan.
Studies on Botox for Pain Relief in Facial Neuralgia
Many studies have found that Botox can help people by:
- Reducing their pain levels
- Lowering the number of their daily pain attacks
- Increasing their pain-free periods
- Improving their sleep
- Improving the overall quality of their life
The good news is that serious side effects are uncommon.
You may experience some temporary side effects, such as:
- Mild swelling
- Bruising
- Temporary weakness in part of your face
- Slight unevenness of your facial movements
- Tenderness where you were given the injections
These side effects are usually mild and may improve within a few weeks.
So far, the results are really promising. But researchers are still studying about the best Botox dose, where the most effective injection sites are, how often the patient should repeat the treatment, and if Botox is safe to use long term.
Alternatives to Botox
Trigeminal Nerve Block
Your doctor may recommend a trigeminal nerve block if Botox is not suitable to you or does not give you enough relief.
This treatment involves injecting a local anaesthetic, sometimes with steroids near the trigeminal nerve to block your pain signals.
A trigeminal nerve block may:
- Gives you a quick pain relief.
- Reduce your pain attacks for a short time.
- Helps you to know where the pain is coming from.
- Offer temporary relief while you are waiting for other treatments.
You may need to repeat the treatment as it is usually temporary.
Other Medication Option
In the UK, people who have trigeminal neuralgia are usually given medication as their first treatment.
- Common medicines include:
- Carbamazepine
- Oxcarbazepine
- Lamotrigine
- Baclofen
- Gabapentin (for some people)
If these medicines do not work well with you or may give you some troublesome side effects, your specialist may recommend other procedures, such as:
- Microvascular decompression: surgery that can relieve the pressure on your trigeminal nerve.
- Radiofrequency treatment: uses heat to reduce your pain signals.
- Balloon compression: gently compresses part of your nerve to relieve the pain.
- Stereotactic radiosurgery: uses focused radiation to target your nerve without an operation.
The best treatment for you depends on several factors, including:
- Your age and overall health
- The cause of your trigeminal neuralgia
- Your MRI scan results
- How severe your symptoms are
- Your personal preference and treatment goals
Conclusion
If you have trigeminal neuralgia, and you have not found enough relief from other treatments, you may consider trying Botox. Although it is not specifically licensed for trigeminal neuralgia in the UK, research suggests that it may reduce the pain and the frequency attacks in some patients.
However, Botox is not a cure and may not work for everyone. There are other treatments you may try and that includes medication and nerve blocks. You may also consider surgery if you really need it.
If you are considering getting Botox, speak with a neurologist or facial pain specialist. They can help you understand if the treatment is right for you. They will also explain about the potential risks and benefits you can get from the treatment.
