# Carbamazepine 100 mg ## Short Description Carbamazepine 100 mg is a **prescription anticonvulsant and nerve-pain medicine**. It is primarily used to control certain types of seizures and to treat **trigeminal neuralgia**. It may also be prescribed for other conditions in specific circumstances. ## Key Benefits * Helps control certain types of seizures * Helps reduce abnormal electrical activity in the brain * Provides relief from nerve pain associated with trigeminal neuralgia * May help stabilize certain abnormal nerve signals * Can reduce the frequency of seizures when used appropriately ## Uses / Indications Carbamazepine 100 mg may be prescribed for: * **Focal (partial) seizures** * **Generalized tonic-clonic seizures** in appropriate patients * **Trigeminal neuralgia** * Certain other seizure disorders when recommended by a specialist * Other specific neurological or psychiatric conditions only when prescribed by a qualified healthcare professional Carbamazepine is **not effective for every type of seizure** and may worsen certain seizure types. ## How It Works Carbamazepine is an anticonvulsant that primarily works by **blocking voltage-gated sodium channels** in nerve cells. This reduces repetitive, abnormal electrical activity in the brain and helps stabilize nerve signaling. In trigeminal neuralgia, this action can reduce abnormal nerve impulses responsible for severe facial pain. ## Dosage & Administration * Take Carbamazepine 100 mg exactly as prescribed by your doctor * The dose is individualized according to the condition, age, response to treatment and other medicines * Treatment is often started at a lower dose and gradually increased * It may be taken with or after food if it causes stomach upset * Take doses at evenly spaced times as directed * Swallow tablets with water * Do not crush or chew modified-release tablets unless your specific formulation allows it * Do not stop Carbamazepine suddenly, particularly if it is being used to control seizures * If you miss a dose, take it when remembered unless it is nearly time for the next dose * Do not take two doses together to compensate for a missed dose * Your doctor may recommend blood tests to monitor blood counts, liver function and sometimes drug levels ## Side Effects Common side effects may include: * Dizziness * Drowsiness * Sleepiness * Headache * Nausea * Vomiting * Blurred or double vision * Unsteadiness or difficulty coordinating movements * Fatigue * Dry mouth Serious side effects can include: * Severe skin reactions * Low blood cell counts * Liver problems * Severe allergic reactions * Low sodium levels * Mood or behavioural changes * Suicidal thoughts or behaviour Seek urgent medical attention for a severe skin rash, blistering or peeling skin, facial swelling, difficulty breathing, unusual bruising or bleeding, severe weakness, jaundice, confusion or suicidal thoughts. ## Precautions & Warnings * Carbamazepine can cause **drowsiness, dizziness and impaired coordination**; avoid driving until you know how it affects you * Do not stop treatment suddenly without medical advice because seizures may become worse * Carbamazepine can cause serious skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis * People with certain genetic backgrounds may have a higher risk of serious skin reactions; genetic testing may be recommended before treatment in some populations * Carbamazepine can rarely cause serious blood disorders; your doctor may monitor blood counts * Liver function may need monitoring during treatment * Carbamazepine can cause **hyponatremia**, meaning low sodium levels * Tell your doctor if you have liver disease, kidney disease, blood disorders or heart problems * Tell your doctor about all medicines you take because Carbamazepine has many drug interactions * Carbamazepine can reduce the effectiveness of some hormonal contraceptives * Tell your doctor if you are pregnant, planning pregnancy or breastfeeding * Keep out of reach of children ## Drug Interactions Carbamazepine has **many clinically important drug interactions** because it can strongly increase the activity of certain drug-metabolizing enzymes.
