Phenytek

Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your response to phenytoin.

Before having any laboratory test, tell your doctor and the laboratory personnel that you are taking phenytoin.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

Phenytek is part of the drug class:

• Hydantoin derivatives

• Take phenytoin exactly as prescribed. Your healthcare provider will tell you how much phenytoin to take.
• Your healthcare provider may change your dose. Do not change your dose of phenytoin without talking to your healthcare provider.
• Phenytoin can cause overgrowth of your gums. Brushing and flossing your teeth and seeing a dentist regularly while taking phenytoin can help prevent this.
• If you take too much phenytoin, call your healthcare provider or local Poison Control Center right away.
• Do not stop taking phenytoin without first talking to your healthcare provider. Stopping phenytoin suddenly can cause serious problems.

Do not drink alcohol while you take phenytoin without first talking to your healthcare provider. Drinking alcohol while taking phenytoin may change your blood levels of phenytoin which can cause serious problems.

Do not drive, operate heavy machinery, or do other dangerous activities until you know how phenytoin affects you. Phenytoin can slow your thinking and motor skills.

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

Sometimes it is not safe to use certain medications at the same time. Some drugs can raise or lower your blood levels of phenytoin, which may cause side effects or make phenytoin less effective. Phenytoin can also affect blood levels of certain other drugs, making them less effective or increasing side effects.

Taking phenytoin with other drugs that make you sleepy or slow your breathing can increase these effects. Ask your doctor before taking phenytoin with a sleeping pill, narcotic pain medicine, muscle relaxer, or medicine for anxiety, depression, or seizures.

Many drugs can interact with phenytoin. Not all possible interactions are listed here. TELL YOUR DOCTOR ABOUT ALL OTHER MEDICINES YOU USE, and any you start or stop using during treatment with phenytoin. This includes prescription and over-the-counter medicines, vitamins, and herbal products.

Phenytoin is used to control seizures (convulsions) in the treatment of epilepsy. It is also used to prevent and treat seizures that occur during brain surgery. This medicine is an anticonvulsant that works in the brain tissue to stop seizures.
