Allergy medicine for a sinus headache

An antihistamine can reduce sneezing, itching and watery nasal discharge. A corticosteroid nasal spray reduces nasal inflammation when used correctly and consistently. Neither is a general painkiller, and headache without allergy features deserves a broader look.

Allergic rhinitis often presents with nasal itching, repeated sneezing, clear discharge and congestion. Head pain with fever, thick discharge, marked illness, light sensitivity, nausea or sensitivity to sound can point away from a straightforward allergy pattern.

So-called sinus headache can overlap with migraine or accompany a respiratory infection. Decongestant tablets or sprays may relieve blockage briefly, but they are unsuitable for some people; prolonged use of a decongestant nasal spray can also worsen stuffiness.

Notice whether pain follows exposure to dust, pollen or another familiar trigger and whether itchy eyes or sneezing occur at the same time. Use prescribed or labelled allergy treatment as directed, drink fluids, rest, and consider saline nasal rinsing with sterile, distilled or previously boiled and cooled water.

Check combination cold-and-allergy products carefully so you do not duplicate ingredients. Seek advice before using a decongestant if you are pregnant, take regular medication, or have heart, blood pressure, thyroid, eye or prostate problems.

Call emergency services for a sudden severe headache, new weakness, facial droop, trouble speaking, fainting, seizure, confusion, a stiff neck with fever, or headache after a significant head injury.

Book an assessment when pain keeps returning, steadily worsens, disrupts normal activities, or does not improve when nasal allergy symptoms settle. A clinician can distinguish nasal inflammation from migraine, infection, medication effects and other causes.

Describe where the pain sits, what brings it on, associated symptoms and every product you have tried. Ask whether your pattern fits allergy, whether your nasal-spray technique is correct, and what change should prompt another review.
