Anticonvulsants are drugs to prevent or treat seizures or epilepsy. Anticonvulsants or anticonvulsants are available in various drug forms and should only be used in accordancedoctor's prescription.
Normally, nerve cells in the brain communicate with each other through electrical signals that are present at normal levels. When there is excessive electrical activity in the brain, seizures can occur.
Anticonvulsant or anticonvulsant drugs work by normalizing the electrical activity in the brain, so that seizures can be prevented or treated.
Besides being useful for treating seizures, several types of anticonvulsants can also be used to relieve pain due to nervous disorders (neuropathy), prevent and treat headaches, and treat bipolar disorder.
Warnings Before Taking Anticonvulsants
Anticonvulsants should only be used as prescribed by a doctor. Before using an anticonvulsant, there are several things you should pay attention to, namely:
- Do not use anticonvulsant drugs if you are allergic to these drugs.
- Avoid consuming alcoholic beverages while taking anticonvulsant drugs, as they can worsen side effects.
- Tell your doctor if you are pregnant, breastfeeding, or planning a pregnancy.
- Anticonvulsant drugs can affect the effectiveness of hormonal birth control. See your doctor right away if you experience vaginal bleeding or become pregnant while taking anticonvulsant medications.
- Do not change the type of anticonvulsant medication carelessly while you are pregnant, because there is a risk of causing uncontrolled seizures.
- Avoid activities that require vigilance while taking anticonvulsant drugs, as these drugs can cause dizziness.
- Talk to your doctor about the risks and benefits of anticonvulsant drugs, as they can affect your mood and increase your risk of depression and suicidal ideation.
- Do not change or stop taking anticonvulsant drugs without your doctor's permission, because they can cause repeated seizures.
- Tell your doctor if you have a history of porphyria, myasthenia gravis, sleep apnea, heart disease, lung disease, liver disease, thyroid disease, kidney disease, osteopenia, osteomalacia, osteoporosis, hypoalbuminemia, alcoholism, mental disorders, glaucoma, and diabetes.
- Tell your doctor what medications you are taking, including vitamin supplements and herbal remedies.
- Tell your doctor if you plan to have dental work or surgery.
- During treatment with anticonvulsants, check with your doctor regularly. Benzodiazepine-type anticonvulsants can be addictive, so they shouldn't be used for more than 1 month.
- See your doctor right away if you have an allergic reaction to a medication or an overdose after using an anticonvulsant medication.
Side Effects and Dangers of Anticonvulsants
Anticonvulsants can cause different side effects in each user. Some of the side effects that often appear are:
