Oak pollen allergy
Oak pollen allergy in spring.
About oak pollen allergy
Oak is a widespread tree across the UK, and it is a significant source of tree pollen in spring, typically releasing pollen from around April into May, somewhat later than birch but overlapping with it. Oak produces large amounts of wind-carried pollen, which adds to the spring pollen burden for people whose hay fever starts before the summer grass season. When a sensitised person inhales oak pollen, the immune system produces IgE antibodies against its proteins, triggering histamine release and the familiar symptoms of hay fever. Tree-pollen allergy is common, and oak is a recognised contributor to spring symptoms.
The usual presentation is seasonal allergic rhinitis, with sneezing, a runny or blocked nose and itchy, red, watering eyes during the oak season. As with other tree pollens, exposure can worsen asthma, causing cough, wheeze and chest tightness, and can aggravate eczema in susceptible people. There is some overlap between tree pollens, so people allergic to birch may also react to oak. Symptoms are rarely life-threatening, but they can disturb sleep and affect concentration, school and work in spring.
Helpful seasonal measures include checking pollen forecasts, keeping windows shut when counts are high, wearing wraparound sunglasses, washing off pollen and avoiding drying laundry outdoors. Diagnosis uses skin-prick or specific-IgE tests. Treatment follows the usual ladder of antihistamines and steroid nasal sprays, with allergen immunotherapy an option for selected, severe cases. See a GP if symptoms are hard to control or significantly disrupt daily life.

Allergy safety: what everyone should know
Mild-to-moderate reaction signs
- Itching, hives or a raised rash
- Swelling of lips, face or eyes
- Tingling mouth, sneezing, runny nose
- Stomach pain, nausea or vomiting
Anaphylaxis — call 999 (UK) or 112 (EU) immediately
- Difficult or noisy breathing, wheeze, persistent cough
- Swelling of the tongue or tightness in the throat
- Dizziness, collapse, pale and floppy (young children)
- Use an adrenaline auto-injector (e.g. EpiPen) at once if prescribed, then call an ambulance even if symptoms improve
Allergy or intolerance? A true allergy involves the immune system and can escalate quickly; an intolerance (e.g. lactose intolerance) is unpleasant but not life-threatening. The symptoms overlap, so self-diagnosis is unreliable.
Getting tested: home-testing kits based on IgG are not diagnostically valid. If you suspect an allergy, ask a GP for referral to an allergy clinic for skin-prick or specific-IgE testing and a supervised food challenge where appropriate.
