I've been on Dilantin since I was a kid so I can't say what it's like to be off of it for two days. But I will say that being administered any medication via i.v. can take longer to run through your system. My only advice is the same with any medication, drink plenty of water.
btw - loss of balance and slurred speech are also common side effects of sleep deprivation. Be well💜

Depends on the dosage you were given. Also depends on the meds you have taken before you reached the hospital. Did they give you a generic brand or did they give you a name brand of Dilantin? May have been a conflict with the meds you take at home and the Dilantin you were given, and it takes a little longer to get out of your system. I have had that happen to me before.

i know for a fact that botox will stay in your system months to a year after the effects where off. i didn't take dilantin for vary long (it increase seizure for me) so idk how long it took for the effect to ware off.

I'm sorry you went through that experience. I've never had that med. I've been on Keppra & experienced side effects. Severe mood swings, hostility, & it altered my personality in a not very pleasant way toward others. Doing much better on Vimpat (generic name). Not experiencing any real side effects but it's doing a great job controlling my nocturnal seizures. I wish you the best. Hugs!!!

Dilantin is awful. I’ve taken it in the late 1990’s my weight gained approximately 25 pounds, felt like a zombie and always tired. There’s plenty of other Meds out there to use!
