Mild side effects may include drowsiness or slight dizziness, which usually lessen with proper dosage and medical guidance. Tylenol is gentle on the stomach, and Xanax promotes relaxation. When used responsibly under supervision, both medications can safely improve comfort, reduce stress, and enhance overall well-being without causing serious complications.
