Do you suffer from hay fever? For some people, it’s a few annoying sneezes. For others, it’s itchy eyes, constant congestion, poor sleep, and feeling generally miserable for weeks or months, making it essential to find a treatment that actually works.
There are plenty of hay fever treatments out there, but the best one depends on your symptoms, how severe they are, and what triggers your allergies. Some people do well with a once-daily antihistamine tablet, while others need more targeted treatments, a combination of medicines, or prescription-strength allergy relief.

What is the best hay fever treatment?
There’s no single “best” hay fever treatment for everyone.
The right option often depends on which symptoms bother you most. Your pollen trigger can also make a difference. Tree pollen tends to peak in spring, grass pollen is the most common summer trigger, and weed pollen can continue into late summer and early autumn.
But in reality, choosing the right treatment is usually more about how your hay fever affects you than exactly what pollen is causing it.
If sneezing and a runny nose are driving you mad…
Antihistamine tablets are where most people start. They’re convenient, easy to take, and often work well for classic hay fever symptoms like sneezing, itching, and a streaming nose.
These medicines block histamine, the chemical your body releases when it reacts to allergens like pollen (2). This makes them effective during tree, grass, or weed pollen season, as well as helping with general allergies. But not all work in exactly the same way:
Second-generation antihistamines, such as Cetirizine, Loratadine, and Fexofenadine, are usually the first choice for hay fever. They’re longer-lasting, generally less likely to cause drowsiness, and convenient to take once a day.
First-generation antihistamines, such as chlorphenamine (Piriton), work faster but are much more likely to make you feel sleepy. They also require dosing every 4 to 6 hours. Because of this, they’re usually better suited to unexpected allergy flare-ups rather than day-to-day hay fever management.
If one antihistamine doesn’t seem to help much, that doesn’t necessarily mean antihistamines won’t work for you. Sometimes switching to a different option makes all the difference.
Antihistamines are available as nasal sprays instead of tablets. By delivering the medicine directly into the nose, they work quickly to block histamine locally and can help with sneezing, itching, and a runny nose. But they’re often less effective if congestion is your biggest problem.
If your nose feels completely blocked…
A blocked nose can be one of the most frustrating hay fever symptoms, particularly if it starts affecting sleep. If that sounds familiar, these two other types of nasal sprays may be a better fit.
Steroid nasal sprays – These reduce inflammation inside the nose, making them good for ongoing congestion, swelling, and sneezing. The downside is although they do start working from first administration, it takes a while to build up into its 'therapeutic window' (the level to which it becomes effective) therefore regular use to get the most benefit is essential or starting a few weeks before (3).
Decongestant nasal sprays – These work much faster to quickly unblock your nose, but they’re only designed for short-term use. Using them for too long can actually make congestion worse.
Grass pollen season is often when blocked noses become a bigger issue, so this type of treatment can be especially helpful during peak summer months.
If itchy, watery eyes are your biggest problem…
For some people, the worst part of hay fever is the eyes.
If your eyes are constantly itchy, watery, red, or irritated, allergy eye drops can offer targeted relief. They work quickly and are especially helpful during high pollen days, particularly if tree or grass pollen tends to trigger your symptoms.
The downside is that they only help with eye symptoms, so if you’re also congested or sneezing constantly, you’ll probably need something alongside them.

Which hay fever treatment is right for you?
If you’re still feeling overwhelmed by your options, this comparison table should help you see which hay fever treatments are best suited to reduce specific symptoms:
Treatment | Best for | Good to know |
|---|---|---|
Cetirizine | Sneezing, itching, a runny nose, and general hay fever symptoms Fast-ish acting (often within an hour). | Can occasionally cause drowsiness, even though it’s classed as low-drowsy. Good all-rounder. |
Loratadine | Mild to moderate hay fever, especially if you’re sensitive to drowsiness. | Usually very well tolerated and less likely to make you sleepy, though some people find it less effective than other options. |
Fexofenadine | More stubborn hay fever symptoms, people wanting a low-drowsiness option. | Often considered one of the stronger OTC antihistamines. Lowest risk of drowsiness among common options. |
Chlorphenamine (Piriton) | Sudden allergy flare-ups or short-term symptom relief. | Works quickly but commonly causes drowsiness, so not ideal for day-to-day hay fever management. May need to dose multiple times in a day. |
Steroid nasal sprays (e.g. Budesonide, Beconase, Fluticasone) | Blocked nose, congestion, persistent nasal symptoms. | Often one of the most effective hay fever treatments for nasal symptoms, but needs regular use and won’t provide relief instantly (3). |
Antihistamine nasal sprays (e.g. Azelastine) | Runny nose, sneezing, nasal itching when tablets aren’t enough. | Can work faster than steroid sprays and provide more targeted nasal relief than antihistamine tablets (2). |
Decongestant nasal sprays (e.g. Otrivine) | Severe short-term congestion. | Fast relief, but only suitable for short-term use (usually no more than 5–7 days). |
Sodium cromoglicate eye drops | Itchy, red, watery eyes. | Great if eye symptoms are your main problem. Often used alongside tablets or sprays. |
What if your hay fever treatment isn’t working?
If the first treatment you’ve tried isn’t giving you enough relief, that doesn’t mean you’re out of options. Fighting hay fever can be tough, and combining treatments often works better than relying on just one. For example:
Antihistamine tablet + steroid nasal spray if you have general symptoms plus congestion
Antihistamine tablet + eye drops if itchy, watery eyes are a major issue
A nasal spray + eye drops if your symptoms are more targeted
It’s also worth remembering that some treatments take longer to work than others. Steroid nasal sprays, for example, need to be used consistently for several days before you notice their full effect, so stopping too soon may mean missing out on the benefit (3).
If over-the-counter options still aren’t helping, stronger prescription-strength antihistamines like Rupatadine, Xyzal or Desloratadine or combined antihistamine and steroid nasal sprays like Dymista and Ryaltris are available through our Online Doctor service, following an online consultation.
Are there long-term treatments for severe hay fever?
Yes, if your allergies are affecting your sleep, work, or ability to enjoy being outdoors, there are specialist immunotherapy treatments that go beyond managing symptoms.
Options like Grazax (targeting grass pollen allergens) and Itulazax (targeting tree pollen allergens) work by gradually reducing your immune system’s response to the allergen over several years, which can make your allergies milder.
These treatments must be started by an allergy specialist, usually after allergy testing, with the first dose taken under supervision. Once treatment has been established, Oxford Online Pharmacy may be able to continue your prescription.
Still unsure which allergy treatment to get?
With so many hay fever treatments available at Oxford Online Pharmacy, choosing the right one can feel overwhelming, especially if you’re dealing with a mix of symptoms or have other things to consider, like asthma, pregnancy, or regular medications.
