Various side effects may occur, including dizziness, headache, drowsiness, blood pressure drop, arrhythmia, rash, nausea, abnormal liver function, etc. If any abnormal symptoms occur, medical consultation should be sought immediately. Overdosage may carry the risk of excessively low blood pressure; thus, adherence to prescribed dosages is crucial, and care should be taken regarding dizziness from sudden position changes due to blood pressure drop.
