In a small study, phenytoin-induced seizures occurred most often in patients with serum phenytoin concentrations of 50 mcg/ml or higher.[393] Peripheral neuropathy, usually occurring weeks to months after drug initiation, has also been reported in patients receiving phenytoin. A single case report describes the onset of neuropathy within a few hours of drug administration.[9780]

Hello AB, welcome to the medhelp forum. Phenytoin can cause certain side effects like dizziness and mental confusion. Some people may also manifest incoordinate movements. Weight gain is not a documented side effect. It could be related to your alcohol consumption or wrong dietary habits and lack of exercise. An occasional one or two drink may be fine but moderate or large amount can cause significant increases in blood levels of phenytoin due to induction of hepatic enzymes.

Folic acid supplementation in folate-deficient patients with epilepsy changes the pharmacokinetics of phenytoin, usually leading to lower serum phenytoin concentrations and possible seizure breakthrough..."

Since you can't go back and start all over again, you can take a small dose. It has been observed that as los as 1mg dose can perturb phenytoin’s levels, You may take doses lower than 1mg/day.
Acute alcohol consumption increases the availability of phenytoin (Dilantin) and the risk of drug-related side effects. Chronic drinking may decrease phenytoin availability, significantly reducing the patient's protection against epileptic seizures, even during a period of abstinence. Any form of alcohol, even beer is contraindicated for some time when you are weaned off dilantin.

Thank you for your question, you are relatively fine with Phenytoin and the seizure episodes in a form of lack of speech are the residue of a generalized type seizure. I don’t have a full description of your consciousness during the lack of speech episodes to decide whether this start is a partial epilepsy which can continue in a generalized or it is a generalized one from the first moment..
Just looking for anymore information or advise about withdraws from Fioricet / I have been taking this medication from years from Migrain headaches, it's seemed the longer I was on it the less it helped so I would increase my doses because I could not get rid of my headaches the other day I just stopped using it because it was like just this non stop headache.
During those times I had not yet been diagnosed and was able to go back to life like normal, however after the diagnosis and being on phenytoin and switching to oxcarbazepine i am feeling awful. Dizzy, nauseated, moody, extremely tired, severe headaches that come and go. All i get from my Neurologist is these are side effects that will eventually go away. Because i never know when these symptoms will come on too strong I have missed a lot of days at work during my probation period.
Does anyone know what can cause Dilantin levels to be too low after taking correct dosage? My levels have been around 3.2 and I take the correct dosage my doctor prescribed of 400 MG a day. 200 in the morning and 200 at night. My doctor thinks I am not taking my Dilantin and I cannot convince him otherwise!!! I don't know what to do or where to find any information about it. Would appreciate any information, please.
Without definitive information about how these substances effect the body in the presence of each other in addition to other medications, you can be risking health consequences.
For instance, I take Phenytoin every day. Yet if I need to take an antibiotic I must avoid the mycin class. Mycins effect the metabolism of Phenytoin in the liver, slowing the elimination of it significantly.
The information you all have provided here is greatly appreciated and not to mention very informative. I'm working on learning everything I can to help two people actually. They're a couple so it's very hard. But I know there are problems with addiction for both of them. I figure the more knowledge I have the more prepared I will be. I have one of them willing to talk to me tonight. He knows what I'm going to be talking about and I'm so surprised he said ok...
Hi everyone,
I'm new to this community.
My neurologist just informed me that Osteoporosis and shrinkage of the Cerebellum are very serious side effects for long term users of Dilantin. Does anyone know more about this?
I've been taking 500mg of Dilantin for over 30 years since I was a teenager, and now I'm terribly worried. Not one of the neurologists had mentioned anything about this over the years, and now at 46, I've learned that I may have severe osteoporosis.
There should be a prescribing information sheet included with a prescription medicine that will list known side effects.
For widespread or stubborn infections, itraconazole tablets have shown good results in curative aspects, but avoid its interaction with other drugs like antacids, astemizole, phenytoin and rifampicin. Most patient think the treatment has not worked if their pale patches do not disappear straight away. Please remember that the patches will take a long time to disappear and the treatment does not equate with disappearance.
I think your local Pharmacist would have this information. If not they will probably get it for you. They are the true experts in medication and prescribing law and best of all their service is free.
I hope you are able to find the answers.
A few weeks ago I woke up with yellow crust on the corner of my lips and it went away in 2 days, and today I woke up and it's in the exact same spot again except a little more then before. It doesn't hurt or itch, it feels like my lips are very very dry. I don't smoke, I have grandmal seizures and my medication is phenytoin and kepra but I didn't read anywhere that would be a side effect so I'm worried this could be a STD or something.
