3. All patients must be taking either a mood stabilizer (i.e. lithium or valproate) (lamotrigine as a mood stabilizer is acceptable for bipolar 2 disorder patients only and not for bipolar I disorder) or an atypical antipsychotic or a combination of these (two mood stabilizers or a mood stabilizer plus an atypical antipsychotic), at therapeutic doses, for mood stabilization. Those taking two atypical antipsychotics are excluded. Combinations of these medications as outlined above, or the combination of any of them with lamotrigine 100-400 mg daily, or the combination of a mood stabilizer plus asenapine 5-20 mg/day, are also permitted.
