3 parenteral progestogens (medroxyprogesterone acetate, northisterone enanthate, and dehydroxyprogesterone acetophenide with estradiol enanthate, DPA) were studied in 907 women during 14,958 cycles over a 10-year period. The findings are summarized in 9 diagrams. The frequency of the principal side effects - intermenstrual bleeding, amenorrhea, headache, dizziness and nervousness - varied with the different substances. Intermenstrual bleeding and amenorrhea were least serious using DPA. When the injections were administered at the appropriate intervals, the drugs were effective and no pregnancies occurred. After suspending the treatment, the menstrual pattern returned to normal and the endometrium was fully regenerated. To date no fetal abnormalities have been reported after discontinuing the treatment.

Divalproex sodium is an anticonvulsant agent approved for use either alone or in combination with other antiepileptic drugs for simple and complex absences seizures and mania. Four double-blind placebo-controlled studies have confirmed that divalproex sodium/valproate is an effective migraine treatment. In all of the clinical studies, whether open, retrospective, or placebo-controlled and double-blind, valproate was an effective preventive treatment for migraine. There was a reduction in the number of migraine attacks, and migraine duration and intensity were also reduced in some instances. It is equally as effective in patients with severe frequent migraines as in those with less severe migraines. In clinical trials, the most frequent adverse events reported by patients treated with divalproex sodium were nausea, asthenia, dyspepsia, dizziness, somnolence, and diarrhea, with most adverse events being mild to moderate in severity.

Older generation antiepileptic drugs like Phenobarbital (Luminal), carbamazepine (Tegretol), phenytoin (Dilantin), and valproic acid (Depakote) have several shortcomings such as suboptimal response rates, significant adverse effects, several drug interactions, and a narrow therapeutic index. New antiepileptic drugs have been developed in the last decade to overcome some of these problems. These newer generation antiepileptics like felbamate (Felbatol), gabapentin (Neurontin), lamotrigine (Lamictal), levetiracetam (Keppra), oxcarbazepine (Trileptal), tiagabine (Gabitril), topiramate (Topamax), and zonisamide (Zonegran) have better tolerability profiles, low interaction potential, and significantly less enzyme inducing or inhibiting properties. As the use of antiepileptic drugs has expanded to include treatment of neuropathic pain, newer side effects have been reported. In addition to the common side effects of antiepileptic drugs, like dizziness, drowsiness, and mental slowing; other side effects like weight gain, metabolic acidosis, nephrolithiasis, angle closure glaucoma, skin rash, hepatotoxicity, colitis, and movement and behavioral disorders, to name a few, have been brought to our attention. This review is an attempt to highlight the features and incidences of some of these side effects.
