For anticonvulsants the recommended dose of Folic Acid is 5mg, compared with 0.5mg that is usually recommended.
My doctor has said he will put me on Seroquel when I get pregnant (not quite yet!) coz its really safe, he wasn't to happy about Lamactal or Tegretol (but I hate tegretol so I am never taking it again!) as a antidepressant SSRI and SNRIs are safer and have been used for longer during pregnancy.
Haven't heard of Klonopin, must be marketed under a diff name here.
