In particular, patients on alpha-1 blockers should not generally use this medication together, but if it is necessary, it should be administered with caution.

When taking this medication, symptoms of blood pressure drop such as syncope or loss of consciousness may occur, so if any unusual symptoms appear, the medication should be stopped immediately and medical attention should be sought.
