Phenytoin Overview

Phenytoin /fnton/ is a hydantoin-derivative anticonvulsant drug used primarily in the management of complex partial seizures and generalized tonic-clonic seizures. Phenytoin is also used to prevent seizures following neurosurgery.

What are the side effects of Eptoin 300 ER ? My Sister was advised to take this in stead of 3 regular Eptoin 100 Mg. Is there any additional advantage ? ## Eptoin contains the active ingredient Phenytoin, it is an anti-epileptic, used to help prevent seizures. The side effect profile does not change when a dosage is altered, however, taking more at once or raising the dosage may cause them to be more severe for a few weeks, until her body adjusts to the medication. These may include: nausea, drowsiness, mild skin rash, itching and insomnia. The advantage to taking the 300mg ER tablet is that it is a time released formulation, so it is specially formulated to work for the entire day, so she gets the control she needs, without having to remember to take multiple pills each day.

This generic was given to me when I refilled my RX that had been Mylan 1560 white/lavender capsule. I haven't felt good, blahs, no energy, headache which I finally realized it started around the time I started taking the above medication. ## Hello, Deanna! How are you? I'm sorry about the way you're feeling. There can be slight fluctuations from one generic to another, so this one may have a slightly lower or higher dosage than the prior one. The difference is usually insignificant and your body will usually adjust in about a week or so. Have things improve at all, yet? How are you feeling?
