While last year's streaming eyes and relentless sneezing fits may feel like a distant memory, spring is rapidly approaching, and a leading pharmacist has issued a timely warning to start preparing for the 2026 hay fever season now.
Proactive Prevention Strategy
Deborah Grayson, who shares expert advice as The Godmother of Pharmacology on TikTok, has told the Daily Mail that hay fever sufferers should consider beginning their antihistamine regimen immediately, particularly if tree pollen triggers their symptoms.
"You should start taking antihistamines two to four weeks before hay fever season," Ms Grayson emphasized. "This enables the body to block the reaction before symptoms can develop and minimises the risk of a reaction to pollen."
Understanding Pollen Seasons
Hay fever, an allergic reaction to pollen, typically begins in late March as tree pollen peaks and can persist through September. Different pollen types affect sufferers at various times:
- Tree pollen (such as birch) generally runs from March to mid-May
- Grass pollen season spans from mid-May to July
- Weed pollen can cause symptoms from late June to September
The Widespread Impact of Hay Fever
The condition affects approximately one quarter of adults and one in ten children across the population. Symptoms including sneezing, coughing, and sore, red, itchy eyes can prove debilitating for many sufferers.
Concerningly, two-thirds of those affected report that hay fever negatively impacts their daily lives, causing poor sleep patterns, persistent fatigue, and decreased concentration levels. Additionally, one in five sufferers are compelled to take time off work due to the severity of their allergic reactions.
How Antihistamines Work
Antihistamines, available over-the-counter, function by blocking histamine—a chemical released by the immune system during allergic reactions. These medications represent the primary treatment for hay fever symptoms.
"When the body is challenged by an allergen such as pollen, the immune cells in our tissues called mast cells break down to release the compound histamine," explains Ms Grayson. "The histamine then attaches to one of the body's histamine receptors and triggers those symptoms we typically see in hay fever and other allergies."
By blocking histamine's action on these receptors, antihistamines effectively reduce both the likelihood and severity of allergic symptoms.
Choosing the Right Antihistamine
Two primary types of antihistamines exist: sedative and non-drowsy formulations. Ms Grayson advises particular caution with sedative varieties, which can interact with other medications.
"Non-drowsy antihistamines are generally safe to take with other medications, but it is always wise to double check with your pharmacist or doctor," she recommends. "However, sedative antihistamines will increase the effect of medications which also have drowsiness as a side effect."
Those taking sedative antihistamines should abstain from alcohol, as combining them can intensify effects. While this specific interaction doesn't apply to non-drowsy versions, alcohol can still affect how the body processes histamine and potentially worsen allergy symptoms.
Long-Term Considerations
Non-drowsy antihistamines are generally considered safer for long-term use as they don't cause drowsiness that could affect driving ability. Concerns exist regarding prolonged use of sedative antihistamines and potential increased dementia risk due to their impact on neurotransmitter signalling.
"Taking short term or as prescribed is recommended," Ms Grayson advises regarding sedative options.
Unlike some medications, antihistamines don't require tapering—sufferers can begin at a normal dose immediately. There's no specific optimal time for consumption, though Ms Grayson suggests experimenting to find what works best individually.
Complementary Management Strategies
Alongside antihistamine use, the NHS recommends several practical methods to help hay fever sufferers manage their symptoms:
- Applying petroleum jelly around nostrils to trap pollen
- Wearing wraparound sunglasses, masks, or wide-brimmed hats to prevent pollen entering eyes and nose
- Showering and changing clothes after being outdoors to avoid spreading pollen indoors
- Keeping windows and doors closed when possible
- Regular vacuuming and dusting with damp cloths
Safety Considerations
While most people can safely take antihistamines, certain groups should consult healthcare professionals before beginning medication:
- Pregnant or breastfeeding individuals
- The very young or elderly
- Those taking other medications
- People with underlying heart disease, liver disease, or other health conditions
Expert Consensus on Early Preparation
Allergy specialist Dr Adrian Morris of the Surrey Allergy Clinic supports this proactive approach, having previously written: "Silver Birch tree pollen begins early in March, although most hay fever sufferers will have problems when the grass pollens become prevalent a little later in April to May. But now is the time to prepare as prevention is better than cure."
Dr Morris recommends starting once-daily non-sedating antihistamines two to three weeks before the season commences. Those sensitive to tree pollen should have already begun medication, while others need to start by mid-March.
"Take your antihistamine every day during the season for best results," he advises. "Low dose nasal steroid sprays are very effective if taken together with antihistamines for breakthrough symptoms."
