It is an odd dosage. I have been on the 100 mg all of my life, and they are now saying that the pharmaceutical companies are no longer making the 100 mg tablets. They are also saying without any logical explanation that the 97.2 mg is the equivalent dosage of the 100 mg of phenobarbital. I am also on Depakote, Was on 1000mg ER, but had to drop 250 mg a couple months ago which is fine. However, I don`t like playing around with the Phenobarbital dosage when it comes to my seizures. Just do not understand how they consider 97.2=100 mg. Most of all why they are not making the 100 mg anymore. Also have been under much stress recently and this has made it worse. Since 6/6 I have felt so stressed that it feels as though a seizure could come on. I`m on 115 mg phenobarbital right now. Last night I considered asking my Dr. to give me 2 of the 60 mg per day.

Considering I`ll soon be 2.8 mg short after I run out of this bottle, and considering the way I`ve been feeling, maybe a couple more mg will not hurt. Just don`t want to have a seizure. Also, the drug stores or certain ones may have a few left over 100 mg tablets, but one gone they will only be getting in the 97.2 mg. I hope something changes and they go back to making the 100mg. I have a feeling that this is all about money, somehow some way. Thanks for your answer kaismama.
