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 ex cap 100 mg bright orange capsule writing on taro phn
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?

phenytoin ex cap 100mg side effects
I have been taking phenytoin for 15 years for seizures due to abnormal vessel between speech and memory part of my brain. I fill my meds at Wal-Mart. Here lately they switched me to phenytoin made by a different company and it has me all messed up.I was taking a brand made by a company AMN. Now they switched to a company called Mylan. I am tired of this.Once they gave me phenytoin that was orange color. Talk about being on edge, I was. What is the difference in one company and the other? Now I feel like I am going to have a seizure. I feel totally different.I am scared and don't like feeling weird.

hey need to know
hi, im a female of 23yrs old, im taking eptoin 100mg twice a day one tablet in morning and 2 doses at night,i will be married by september2014, can i take eptoin100mg during my pregnancy time? im taking eptoin100mg from 2007. ## Hi Kutti, Eption (Phenytoin) falls in pregnancy category D here in the USA, which indicates "Positive evidence of risk". So it is advisable to work closely with your doctor during the pregnancy to ensure your child's health. They may decide that the benefits of your medication outweigh the risks, but that is ultimately for you and them to decide since they are going to be familiar with your full medical history. I hope this helps and wish you good health!

eptoin 300 er
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. Are there ...
