In the states, it's called Depakote. Minimum dosage is 500 mg which is below a therapeutic dose. I take 500 because I also take another mood stabilizer along with it. Usual dosage for the average person here is 1000-3000mg if it is taken alone.

Remember, if you take an SSRI without enough mood stabilizer to counter it, it will aggravate your mania or hypomania. I did that for years while misdiagnosed. That requires more and more benzo's to calm you. Get enough mood stabilizer into you so you don't have that problem. The SSRI's work well for the depression but can wreak havoc on your mania. It can become a viscious cycle.

I take Depakote and Topamax for hypomania, Effexor ER and Abilify for depression, and Diazapam prn for anxiety, as I also have PTSD. The Topamax has a cognative dulling effect so I keep the dosage as low as possible (I'm dull enough without it!).
