Can you take Buspar & clonazepam & Seroquel?

No, why Buspar? The clonazepam should be adequate or dose increased. Unless your already taking 4mg? As for Seroquel it has some nasty side effects and over time these will present themselves. Hand cramps, falling, and it stays with you for a long time. It will knock you out for sleep yet you may need to increase the dose. You may want to give it up. Buspar does what clonazepam should do fine. Change the dose to taking 0.5mg twice during the day and three 0.5mg at bedtime. If needed increase to three 0.5mg during the day and three 0.5 at bedtime. If needed add another 0.5mg at bedtime. Then your taking less medication and that can be beneficial. Taking all 3 is overkill and there are interactions. Seroquel is beginning to show up with negative data some bad reactions.
