portant. Your doctor may order additional tests to rule out other conditions.

However, over time, some people with the condition may stop responding to medications, or they may experience unpleasant side effects. For those people, injections or surgery provide other trigeminal neuralgia treatment options. If your condition is due to another cause, such as multiple sclerosis, your doctor will treat the underlying condition. Medications To treat trigeminal neuralgia, your doctor usually will prescribe medications to lessen or block the pain signals sent to your brain. Anticonvulsants. Doctors usually prescribe carbamazepine (Tegretol, Carbatrol, others) for trigeminal neuralgia, and it's been shown to be effective in treating the condition. Other anticonvulsant drugs that may be used to treat trigeminal neuralgia include oxcarbazepine (Trileptal, Oxtellar XR), lamotrigine (Lamictal), valproate and phenytoin (Dilantin, Phenytek, Cerebyx). Other drugs, including clonazepam (Klonopin), topiramate (Qsymia, Topamax, others), pregabalin (Lyrica) and gabapentin (Neurontin, Gralise, Horizant), also may be used. If the anticonvulsant you're using begins to lose effectiveness, your doctor may increase the dose or switch to another type. Side effects of anticonvulsants may include dizziness, confusion, drowsiness and nausea. Also, carbamazepine can trigger a serious drug reaction in some people, mainly those of Asian descent, so genetic testing may be recommended before you start carbamazepine. Antispasmodic agents. Muscle-relaxing agents such as baclofen (Gablofen, Lioresal, Ozobax) may be used alone or in combination with carbamazepine. Side effects may include confusion, nausea and drowsiness. Botox injections. Small studies have shown that onabotulinumtoxinA (Botox) injections may reduce pain from trigeminal neuralgia in people who are no longer helped by medications. However, more research needs to be done before this treatment is widely used for this condition. Surgery Surgical options for trigeminal neuralgia include: Microvascular decompression. This procedure involves relocating or removing blood vessels that are in contact with the trigeminal root to stop the nerve from malfunctioning. During microvascular decompression, your doctor makes an incision behind the ear on the side of your pain. Then, through a small hole in your skull, your surgeon moves any arteries that are in contact with the trigeminal nerve away from the nerve, and places a soft cushion between the nerve and the arteries. If a vein is compressing the nerve, your surgeon may remove it. Doctors may also cut part of the trigeminal nerve (neurectomy) during this procedure if arteries aren't pressing on the nerve. Microvascular decompression can successfully eliminate or reduce pain for many years, but pain can recur by 10 years in three out of 10 people. Microvascular decompression has some risks, including decreased hearing, facial weakness, facial numbness, a stroke or other complications. Most people who have this procedure have no facial numbness afterward. Brain stereotactic radiosurgery (Gamma knife). In this procedure, a surgeon directs a focused dose of radiation
