Phenytek Reviews

For Seizures "I had my first ever seizure on 8/4/93; one day before my 24th birthday, out of the 'clear blue.' I was first prescribed 400mg of Dilantin daily. I experienced muscle spasms/twitches, sleeplessness at night [and] sleepiness during my waking hours. I was switched to 400mg of Phenytek daily. At first the same symptoms persisted, but subsided over time. I have been on both Dilantin and Phenytek for 22 years; currently on Phenytek and my seizures are controlled, with minor/minimal side effects; occasional muscle twitching and/or headaches remedied with Tylenol. I hold down a full-time job, and I drive, so my #1 priority every night is to take my meds. So far, so good....."


For Seizures "I have been on this medicine for almosy 6 years. I have not had any side effects as of yet. I am monitored by my doctor every 6 months. This medicine has changed my life I was not able to do things such as drvie or even work. Since on the meds I have been seizure free and living my life."


For Epilepsy "I've been taking this medicine for years. I was having difficulties keeping my medicine levels in the proper zone. The extended release has been great. I'm in a small group of people who need their Dilantin level slightly above the 10-20 range. I'm able to stay at 20-22 with the proper dosages that have been prescribed for me. I cannot take the generic brand. When I was on the generic, my levels were not as stable."
