Risperidone (3 mg) + Trihexyphenidyl Hydrochloride (2 mg) is a combination medication used to treat schizophrenia by managing its mood and behavior symptoms with risperidone and reducing antipsychotic-induced movement problems, such as stiffness or tremors, with trihexyphenidyl. This fixed-dose tablet balances brain chemicals and requires a doctor's prescription and supervision to manage symptoms of schizophrenia, bipolar disorder, or other psychiatric conditions.
