You will usually need to take this medicine at a low dose once or twice a day, with the dose slowly increasing up to four times a day until it provides satisfactory pain relief. Carbamazepine often causes side effects, which may make it difficult for some people to take.
These include:. You should speak to your GP if you experience any persistent or troublesome side effects while you are taking carbamazepine, especially allergic skin reactions, as these could be dangerous.
Carbamazepine has also been linked to a number of less common but more serious side effects, including thoughts of self-harm or suicide. You should immediately report any suicidal feelings to your GP. If this is not possible, call the NHS 24 service. Carbamazepine may stop working over time. If this occurs, or if you experience significant side effects while taking it, you should be referred to a specialist to consider alternative medications or procedures.
There are a number of specialists you may be referred to for further treatment, including neurologists specialising in headaches, neurosurgeons and pain medicine specialists for example, at a pain clinic. In addition to carbamazepine, there are a number of other medications that have been used to treat trigeminal neuralgia, including:. None of these medications are specifically licensed for the treatment of trigeminal neuralgia, which means they have not undergone rigorous clinical trials to determine whether they are effective and safe to treat the condition.
However, this is largely only because trigeminal neuralgia is a rare condition, and clinical trials are difficult to carry out on such a painful condition because giving some people an inactive, "dummy" medication placebo to compare these medications to would be unethical and impractical.
However, many specialists will prescribe an unlicensed medication if they think it is likely to be effective and the benefits of treatment outweigh any associated risks. If your specialist is considering prescribing an unlicensed medication to treat trigeminal neuralgia, they should inform you that it is unlicensed and discuss possible risks and benefits with you. With most of these medications, the side effects can be quite difficult to cope with initially. Not everyone experiences side effects, but if you do, try to persevere because they do tend to diminish with time or at least until the next dosage increase, when you may find a further period of adjustment is necessary.
Talk to your GP if you are finding the side effects unbearable. If medication does not adequately control your symptoms or is causing persistently troublesome side effects, you may be referred to a specialist to discuss the different surgical and non-surgical options available to relieve your pain.
There a number of procedures that have been used to treat trigeminal neuralgia, so you will need to discuss the potential benefits and risks of each treatment with your specialist before making a decision. It is wise to be as informed as possible and to make the choice that it right for you as an individual. If one procedure does not work, you can always try another or remain on your medication temporarily or permanently.
Some of the procedures that can be used to treat people with trigeminal neuralgia are outlined below. There are a number of procedures that can offer some relief from trigeminal neuralgia pain, at least temporarily, by inserting a needle or thin tube through the cheek and into the trigeminal nerve inside the skull.
These are known can "percutaneous" through the skin procedures, and they are carried out using X-rays to guide the needle or tube into the correct place while you are heavily sedated with medication or under a general anaesthetic where you are asleep. Percutaneous procedures that can be carried out to treat people with trigeminal neuralgia include:.
These procedures work by deliberately injuring or damaging the trigeminal nerve, which is thought to disrupt the pain signals travelling along it. You are usually able to go home the same day, following your treatment. Overall, all of these procedures are similarly effective in relieving trigeminal neuralgia pain, although there can be complications with each, and these vary with the procedure and the individual. The pain relief will usually only last a few years, and sometimes only a few months.
Sometimes these procedures do not work at all. The major side effect of these procedures is numbness of part or all the side of the face, and this can vary in severity from being very numb or just pins and needles.
The sensation, which can be permanent, is often similar to that following an injection at the dentist. Very rarely, you can get a combination of numbness and continuous pain called anesthesia dolorosa, which is virtually untreatable. The procedures also carry a risk of other short- and long-term side effects and complications, including bleeding, facial bruising, eye problems and problems moving the facial muscles.
An alternative way to relieve pain by damaging the trigeminal nerve that doesn't involve inserting anything through the skin is stereotactic radiosurgery. This is a fairly new treatment that uses a concentrated beam of radiation to deliberately damage the trigeminal nerve where it enters the brainstem. Stereotactic radiosurgery does not require a general anaesthetic and no cuts incisions are made in your cheek. A metal frame is attached to your head with four pins inserted around your scalp a local anaesthetic is used to numb the areas where these are inserted and your head, complete with the frame attached, is held in a large machine for an hour or two which may make you feel claustrophobic while the radiation is given.
The frame and pins are then removed, and you are able to go home after a short rest. It can take a few weeks — or sometimes many months — for this procedure to take effect, but it can offer pain relief for some people for several months or years. Studies into this treatment have shown similar results to the other procedures mentioned above. The most common complications associated with stereotactic radiosurgery include facial numbness and pins and needles paraesthesia in the face.
This can be permanent and, in some cases, very troublesome. Microvascular decompression MVD is an operation that can help relieve trigeminal neuralgia pain without intentionally damaging the trigeminal nerve. Instead, the procedure involves relieving the pressure placed on the nerve by blood vessels that are touching the nerve or wrapped around it.
This is a major procedure that involves opening up the skull, and is carried out under general anaesthetic by a neurosurgeon. During MVD, the surgeon will make an incision in your scalp, behind your ear, and remove a small circular piece of skull bone. They will then either remove or relocate the blood vessel s , separating them from the trigeminal nerve using an artificial pad or a sling constructed from adjoining tissue.
For many people, this type of surgery is effective in easing or completely stopping the pain of trigeminal neuralgia. Currently, this is the closest possible cure for trigeminal neuralgia. However, it's an invasive procedure and carries a risk of potentially serious complications, such as facial numbness, hearing loss, stroke and even death in around 1 in every cases.
Living with a long-term and painful condition such as trigeminal neuralgia can be very difficult. After the trigeminal nerve leaves the brain and travels inside the skull, it divides into three smaller branches, controlling sensations throughout the face:.
It is reported that , people are diagnosed with trigeminal neuralgia TN every year. While the disorder can occur at any age, it is most common in people over the age of A form of TN is associated with multiple sclerosis MS. There are two types of TN — primary and secondary. The exact cause of TN is still unknown, but the pain associated with it represents an irritation of the nerve.
Primary trigeminal neuralgia has been linked to the compression of the nerve, typically in the base of the head where the brain meets the spinal cord. This is usually due to contact between a healthy artery or vein and the trigeminal nerve at the base of the brain. This places pressure on the nerve as it enters the brain and causes the nerve to misfire. Secondary TN is caused by pressure on the nerve from a tumor , MS, a cyst , facial injury or another medical condition that damages the myelin sheaths.
Most patients report that their pain begins spontaneously and seemingly out of nowhere. Other patients say their pain follows a car accident, a blow to the face or dental work. In the cases of dental work, it is more likely that the disorder was already developing and then caused the initial symptoms to be triggered. Pain often is first experienced along the upper or lower jaw, so many patients assume they have a dental abscess. Some patients see their dentists and actually have a root canal performed, which inevitably brings no relief.
When the pain persists, patients realize the problem is not dental-related. TN1 is characterized by intensely sharp, throbbing, sporadic, burning or shock-like pain around the eyes, lips, nose, jaw, forehead and scalp. TN1 can get worse resulting in more pain spells that last longer. TN2 pain often is present as a constant, burning, aching and may also have stabbing less intense than TN1. TN tends to run in cycles.
Patients often suffer long stretches of frequent attacks, followed by weeks, months or even years of little or no pain. The usual pattern, however, is for the attacks to intensify over time with shorter pain-free periods. Some patients suffer less than one attack a day, while others experience a dozen or more every hour.
The pain typically begins with a sensation of electrical shocks that culminates in an excruciating stabbing pain within less than 20 seconds. The pain often leaves patients with uncontrollable facial twitching , which is why the disorder is also known as tic douloureux.
Pain can be focused in one spot or it can spread throughout the face. Typically, it is only on one side of the face; however, in rare occasions and sometimes when associated with multiple sclerosis, patients may feel pain in both sides of their face.
Certain advanced MRI techniques may help the doctor see where a blood vessel is pressing against a branch of the trigeminal nerve. Most common over-the-counter and prescription pain medicines don't work for people with trigeminal neuralgia, but many modern treatments can reduce or eliminate the pain. The doctor may recommend one or more of these approaches:. Many people who suffer from trigeminal neuralgia successfully manage this condition for many years with medication.
Trigeminal neuralgia drug therapy uses some of the same medicines prescribed for controlling seizures, which includes carbamazepine, gabapentin and similar agents. Regular blood tests may be required for some medications to check your white blood cell count, platelets, sodium levels and liver function. Your neurologist or primary care physician can help you select the best drug and the most appropriate dosage.
Most patients start out on low doses, gradually increasing the dose under clinical supervision until they achieve the best pain relief with the least amount of side effects. Nerve blocks are injections with a steroid medication or another agent made at various parts of the nerve to reduce pain. They may provide temporary pain relief for people with trigeminal neuralgia. Multiple injections are usually needed to achieve the desired relief, and the effects may have different durations for different people.
If medication no longer controls your trigeminal neuralgia pain despite the increased dosage, or if the side effects are intolerable, there are several surgical procedures to consider. It helps to learn about these options before you are in urgent need of relief so you and your doctor have time to evaluate them. Your overall health, age, pain level and the availability of the procedure will all factor in to this decision.
Most people with trigeminal neuralgia are candidates for any of the surgical treatment options — your doctor can help you decide which ones and in what order you should consider them.
The surgery for trigeminal neuralgia is delicate and precise since the involved area is very small. Look for experienced neurosurgeons who see and treat a large number of people with trigeminal neuralgia. There are several kinds of rhizotomies for trigeminal neuralgia, which are all outpatient procedures performed under general anesthesia in the operating room.
The surgeon inserts a long needle through the cheek on the affected side of the face and uses an electrical current heat or a chemical glycerin or glycerol to deaden the pain fibers of the trigeminal nerve. For those undergoing trigeminal neuralgia rhizotomy for the first time, the chemical approach is typically recommended.
Those who have the procedure repeated often benefit from both the chemical and the heat treatment delivered in the same session. The procedure takes about 30 minutes and most patients go home several hours later with less to no pain. Out of the three surgical options, rhizotomy offers the most immediate relief from trigeminal neuralgia pain. You may experience some swelling or bruising of the cheek. Your doctor will prescribe pain medications and, if necessary, give you a plan to gradually discontinue your medications.
Rhizotomy is a recommended surgical treatment for patients with trigeminal neuralgia resulting from multiple sclerosis MS. It is minimally invasive and can be safely repeated, since the pain is more likely to come back due to the progression of MS. There are a few different potential causes of trigeminal neuralgia, including: Pressure on the trigeminal nerve , usually by a blood vessel exiting the brain stem, which wears away the protective coating around the nerve the myelin sheath Multiple sclerosis, a disease that causes deterioration of the myelin sheath Trigeminal nerve compression from a tumor Arteriovenous malformation tangled arteries and veins Injury to the trigeminal nerve due to sinus surgery, oral surgery, stroke, or facial trauma This neuropathic facial pain can take many forms.
What causes trigeminal neuralgia to flare up? Stress Stress is a major intensifier of pain of all kinds. Certain foods Caffeine, sweets, and spicy foods may be triggers for some patients. Alcohol Alcohol interacts with the blood vessels and can also cause dehydration. Touch Even the slightest touch can cause a painful episode. Shaving The combination of water on the face, pulling the hairs as you shave, and the touch of the razor may make pain flare up.
Shower jets Many people with trigeminal neuralgia cannot have shower jets, however gentle, directly on their faces. Change in barometric pressure The swing between high and low pressure can trigger headaches and sinus pain, both of which can be caused by trigeminal neuralgia. Cold and wind Wind on the face, particularly cold wind or even just coldness in general , may constrict blood vessels and cause pain. Blood pressure increase Any pressure in the veins and arteries can place pressure on the trigeminal nerve.
Teeth cleaning Many people with trigeminal neuralgia avoid the dentist, not due to anxiety about their teeth but in fear of the pain that might result. Putting on makeup Even the lightest touch of a makeup brush can stimulate the trigeminal nerve. Smiling Smiling or frowning stimulates the muscles and nerves in the face and can trigger pain. How to avoid trigeminal neuralgia triggers One thing is certain: trigeminal neuralgia triggers are hard to avoid. Anticonvulsants Anticonvulsants are used for prevention of flare-ups and to calm anxiety that may occur when a flare up is imminent.
Botox injections Botox botulinum toxin A injected in the muscles of the jaw may reduce pain when other treatments are not successful. Surgical options Depending on the cause and severity of your trigeminal neuralgia, you may have surgical options.
