Making Informed Choices
Antihistamines are effective for managing allergy symptoms, but understanding their effects on sleep and alertness is crucial. If you experience drowsiness from allergy medication, consider switching to a second-generation antihistamine or timing your dose strategically (taking it before bed if drowsiness occurs).
Remember that drowsiness from antihistamines is a side effect, not a solution for sleep problems. For persistent sleep issues, focus on improving sleep hygiene, addressing underlying health concerns, and consulting with healthcare professionals for appropriate treatment options.
