What is Phenytek?

Phenytek is an FDA-approved prescription medication used to prevent and control seizures. This medication is also known as an anticonvulsant or an antiepileptic medication and works by reducing the spread of electrical activity in the brain that causes seizures.

Phenytek comes in the form of oral capsules and can be taken with or without meals. Read and follow the instructions provided in the medication guide when taking Phenytek. Your doctor will recommend an appropriate dose for you based on an assessment of your current medical condition, other drugs you are currently taking, and your response to treatment. If you develop an upset stomach after taking this medication, you may use it after meals to help reduce this effect.

Use this medication on a regular basis to experience the maximum effect. It is important to take Phenytek at the same time every day to keep the medicine in your body at a constant level. Avoid taking antacids while using this drug as they may reduce the absorption of Phenytek in your body. If you do need to use antacids, take them at least one hour before or one hour after you use Phenytek.

What are the side effects of Phenytek?

Common side effects resulting from the use of Phenytek may include nausea, vomiting, headaches, constipation, dizziness, drowsiness, trouble sleeping, or feelings of nervousness. Consult with your doctor or pharmacist if you experience any of these effects and they persist or worsen. Many patients using this medication do not have any serious side effects.

Seek immediate medical attention if you experience serious side effects such as slow heartbeat, unusual eye movements, loss of coordination, slurred speech, confusion, muscle twitching, blurred vision, excessive hair growth, increased thirst or urination, bone or joint pain, or easily broken bones.

Speak with your doctor or healthcare provider for full medical advice on the risks and benefits involved with using Phenytek as this is not a complete list of side effects.
