Who is "we"? Are you just a family member or friend? If so, I strongly recommend that you NOT play doctor! Even with medications prescribed by a doctor in the past. If you are a doctor, it would seem totally ridiculous and the sign of a quack that you'd be asking these questions to bipolar disorder forum members. A doctor (preferably a psychiatrist) should be consulted. If you care about this manic person, get them proper help. Maybe take them to the hospital ER.
