Let's take a minute to talk about your medication. 

This is phenytoin extended-release. You should take it as directed by your doctor, at the same time each day. Be sure to swallow it whole and do not crush, chew or open it. 

Phenytoin can help control and reduce seizure episodes. 

At first, phenytoin can slow your thinking and motor skills. So, wait until you know how it affects you before doing activities that require you to be alert, like driving. These effects are normal if they are mild and should go away. It can cause changes to your gums, so you should take good care of your teeth. In time, it could also soften your bones. Your doctor can advise you how to manage this. If these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist. But, don't suddenly stop taking it, unless your doctor says it's okay. 

As with any medicine, rare but serious side effects can occur. You should read the medication guide to know what to watch for. In general, you should pay close attention to your body, mood and feelings. If you notice any unusual changes, call your doctor right away. 

To help keep this medicine safe for you, your doctor will order blood tests.

It's important to ask your doctor or pharmacist before taking any herbal remedies or other medicines, even if they don't require a prescription. Also, talk to your doctor before drinking alcohol.
