Allergy Medicine

Choose antihistamine tablets (like cetirizine, loratadine, or fexofenadine) for runny nose, sneezing, and itchy/watery eyes; choose nasal steroid sprays for nasal congestion, sinus pressure, and inflammation. For many people, combining a non-drowsy oral antihistamine with a daily nasal steroid spray gives broader symptom control, but consult a pharmacist or clinician if symptoms are severe or persistent

Oral antihistamines often start working within 1 hour and can last 12–24 hours depending on the formulation; nasal steroid sprays may take several days to reach full effect but provide daily control with continued use. Fast-acting prescription options or injectable treatments differ, so follow labeled instructions and ask a clinician for persistent or worsening symptoms

Common side effects include drowsiness (more with older antihistamines), dry mouth, and nasal irritation for sprays. People who are pregnant, breastfeeding, have certain health conditions (like uncontrolled glaucoma, severe liver/kidney disease, or certain heart conditions), or take other medications should check with a clinician or pharmacist before starting a new allergy medicine

Look for generic versions of active ingredients (cetirizine, loratadine, fexofenadine, fluticasone) and multi-dose or multi-month packs to lower per-dose cost; over-the-counter generics typically cost less than brand-name equivalents. Compare active ingredient, dose, and formulation (tablet vs spray) rather than brand alone to find the for your needs

Non-drowsy second-generation antihistamines generally have fewer interactions, but some allergy medicines can interact with antidepressants, antifungals, antibiotics, or blood pressure drugs; alcohol and sedating antihistamines increase drowsiness and impairment. Always read labels for interaction warnings and check with a clinician or pharmacist if you take prescription drugs

See a doctor if symptoms are severe, persistent despite OTC treatment, cause difficulty breathing or sleep disruption, include recurrent sinus infections or ear problems, or if you need help distinguishing allergies from infections or other conditions. A clinician can confirm diagnosis, recommend prescription options, or refer for allergy testing or immunotherapy
