What is Dilantin?

Dilantin (phenytoin) is an anticonvulsant medication used to treat and prevent seizures in people with epilepsy. It works by reducing the spread of electrical signals in the brain that can cause seizures. Dilantin is also used to prevent seizures that may occur during or after brain surgery.

Dilantin is available in several forms at Canada Pharmacy Depot, including capsule, chewable tablet, extended-release capsule, and oral solution. It is usually taken once or twice a day, with or without food. The dose of Dilantin is adjusted based on the individual patient's needs, and regular monitoring of blood levels is necessary to ensure the safe and effective use of the medication. Common side effects of Dilantin include dizziness, drowsiness, unsteadiness, and nausea. However, some people may experience more serious side effects such as skin rashes, changes in heart rate, or low blood sodium levels. It is important to talk to your healthcare provider if you experience any unusual symptoms while taking Dilantin.

Dilantin (phenytoin) can cause a variety of side effects, some of which are more common than others. Here are some of the most common side effects associated with Dilantin:

Dizziness or drowsiness: This is a common side effect, especially at the beginning of treatment, and can affect a person's ability to perform tasks such as driving or operating heavy machinery.

Unsteadiness: This can lead to a loss of balance and falls, especially in older adults.

Nausea and vomiting: This may occur in some people, especially at the beginning of treatment.

Constipation: This can be a side effect of Dilantin and may need to be treated with additional medication or a change in diet.

Skin rashes: Some people may develop a rash or other skin reaction while taking Dilantin.

Changes in heart rate: Dilantin can affect the electrical activity of the heart, causing changes in heart rate or rhythm.

Low blood sodium levels: Dilantin can cause low levels of sodium in the blood, which can lead to symptoms such as confusion, headache, or muscle weakness.

It is important to tell your healthcare provider if you experience any side effects while taking Dilantin, as they may need to adjust your dose or switch you to a different medication. Additionally, some side effects may go away over time as your body adjusts to the medication, while others may require medical treatment.

Dilantin Drug Interactions

Dilantin (phenytoin) is a medication that can interact with other drugs and potentially alter their effects or increase the risk of side effects. It is important to inform your healthcare provider of all medications you are taking, including prescription and over-the-counter drugs, vitamins, and herbal supplements. This allows your healthcare provider to monitor for any potential drug interactions.

Antacids, for example, can decrease the amount of Dilantin absorbed into the body, making it less effective, when taken at the same time as Dilantin. [1] Hormonal birth control can also be affected by Dilantin, as it can decrease its effectiveness and reliability. Dilantin can increase the effects of blood thinning medications, increasing the risk of bleeding. It can also increase the effects of central nervous system (CNS) depressants, such as alcohol, pain medications, and sedatives, and increase the risk of drowsiness and other CNS effects. In addition, Dilantin can interact with antibiotics such as rifampin, decreasing its levels in the body and potentially making it less effective.

If a significant drug interaction is identified, your healthcare provider may need to adjust your dose or switch you to a different medication. It is important to closely follow your healthcare provider's instructions and communicate any concerns or changes in your symptoms.

Dilantin Dosage

The recommended dosage of Dilantin (phenytoin) varies depending on several factors, including a person's age, medical history, and the condition being treated. The dose is usually adjusted based on the person's response to the medication and their blood levels of phenytoin.

Typically, the starting dose of Dilantin is 100 milligrams (mg) three or four times per day, with a maximum daily dose of 400 mg. The dose may be adjusted upward or downward based on the person's response and tolerance to the medication. Children may be given a lower starting dose and have their dose adjusted based on their weight.

It is important to follow your healthcare provider's instructions and to not adjust your dose without their approval. If you miss a dose, take it as soon as you remember, unless it is close to the time of your next dose. In that case, skip the missed dose and resume your usual dosing schedule. Do not take a double dose to make up for a missed one.

It is important to have regular blood tests to monitor your phenytoin levels and to check for any potential side effects or interactions with other medications. Your healthcare provider will provide specific instructions for your individual needs.
