Factors that affect a Dilantin® dosage include a patient's weight and age, any existing medical conditions he has and other medications he's taking. Other factors affecting a Dilantin® dosage include the amount of Dilantin® that is circulating in the patient's blood and how the medication affects the individual. The standard starting Dilantin® dosage is 100 mg three times daily or 300 mg once per day. The typical Dilantin® dosage for chewable tablets is generally 125 mg taken three times day.
Periodic blood tests are typically used to measure Dilantin® levels in the blood. A doctor can adjust the Dilantin® dosage based on the results of these blood tests. Dilantin® is used in the treatment of certain seizures in epilepsy patients. This condition occurs when sudden short changes in the electrical system of the brain happen. In addition, seizures can occur as an isolated incident or can occur many times throughout the day.
Sometimes, the cause of epilepsy or seizures is not known. Conditions like a stroke, head trauma, or brain tumor also can cause seizures. In addition, genetics, drug and alcohol abuse, and a brain infection can cause seizures. Many different types of seizures are typically grouped together into two categories. These categories are generalized seizures and partial seizures.
Dilantin® is a commonly prescribed medication and most people taking it tolerate it well. Side effects, ranging from mild to severe, may sometimes develop, even at a low Dilantin® dosage. These include dizziness, slurred speech, problems with coordination, and abnormal movements of the eyes. Other side effects that can occur include nausea, vomiting, and gum problems.
Serious Dilantin® side effects are not common but they can occur. These include worsening of seizures, uncontrollable body movements, high blood sugar, and jaundice. Allergic reactions can also occur, such as swelling, hives, rash, and itching. When these occur, a doctor should be notified. If side effects become intolerable, the doctor may be able to either adjust the dosage or prescribe another anti-seizure medication.
Taking Dilantin® while pregnant may not be safe. This medication is classified as a Category D medication, which means it has been shown to pose risks to the fetus. A Category D medication can still be prescribed to a pregnant woman, providing the physician believes the benefits outweigh the risks to the woman and the unborn baby. Dilantin® may also not be safe for breastfeeding women to take because the medication may pass through to breast milk to the newborn.
