Medications compared
Allergic rhinitis medications fall into a few well-understood classes. Know what each does, when to use it, and how to avoid the common mistakes.
Getting the most from your nasal spray
- Blow your noseClear the passages so the medicine can reach the lining.
- Shake and primeShake the bottle and pump a few sprays into the air until a fine mist appears (per label).
- Aim away from the middleTilt your head slightly forward, spray toward the outer corner of the nostril, not the septum.
- Don't sniff hardBreathe in gently — hard sniffing sends the medicine down the throat instead of the nasal lining.
- Be consistentDaily preventive sprays need daily use; benefit builds over several days.
Safety notes worth remembering
Nasal decongestant sprays: use for no more than 3–5 consecutive days. Longer use causes rebound congestion — a worse, harder-to-treat blockage.
Oral decongestants: can raise blood pressure, speed up the heart and disturb sleep. Check with a pharmacist or doctor if you have heart conditions, high blood pressure, glaucoma or an enlarged prostate.
Sedating antihistamines: some first-generation antihistamines cause drowsiness — avoid driving or operating machinery, and prefer non-sedating options during the day.
Pregnancy, breastfeeding and children: many options are safe, but always confirm with your clinician or pharmacist — and read the label for age limits.
Brand names differ by country. This overview is educational — your clinician's advice and the product label always take precedence.
