What works best for eye allergies
An allergen is an otherwise harmless substance that causes an allergic reaction. Allergic rhinitis, or hay fever, is an allergic response to specific allergens.
Pollen is the most common allergen in seasonal allergic rhinitis. These are allergy symptoms that happen with the change of seasons.
Nearly 8 percent of adults in the United States experience allergic rhinitis of some helpful, according to the American Academy of Allergy, Asthma & Immunology (AAAAI).
Between 10 and 30 percent of the worldwide population may also own allergic rhinitis.
Avoiding exposure to allergens
The best way to hold your symptoms under control is often to avoid the things you’re allergic to, although this is not always practical.
For example, you may be capable to help manage:
- animal allergies by keeping pets exterior as much as possible and washing them regularly
- mould allergies by keeping your home dry and well-ventilated, and dealing with any damp and condensation
- hay fever by staying indoors and avoiding grassy areas when the pollen count is high
- food allergies by being careful about what you eat
- dust mite allergies by using allergy-proof duvets and pillows, and fitting wooden floors rather than carpets
Treating severe allergic reactions (anaphylaxis)
Some people with severe allergies may experience life-threatening reactions, known as anaphylaxis or anaphylactic shock.
If you’re at risk of this, you’ll be given special injectors containing a medicine called adrenaline to use in an emergency.
If you develop symptoms of anaphylaxis, such as difficulty breathing, you should inject yourself in the outer thigh before seeking emergency medical assist.

Medicines for mild allergies are available from pharmacies without a prescription.
But always enquire a pharmacist or GP for advice before starting any new medicine, as they’re not suitable for everyone.
Antihistamines are the main medicines for allergies.
They can be used:
- as and when you notice the symptoms of an allergic reaction
- to prevent allergic reactions – for example, you may take them in the morning if you own hay fever and you know the pollen count is high that day
Antihistamines can be taken as tablets, capsules, creams, liquids, eye drops or nasal sprays, depending on which part of your body is affected by your allergy.
Lotions and creams
Red and itchy skin caused by an allergic reaction can sometimes be treated with over-the-counter creams and lotions, such as:
- moisturising creams (emollients) to hold the skin moist and protect it from allergens
- calamine lotion to reduce itchiness
- steroids to reduce inflammation
Decongestants can be used as a short-term treatment for a blocked nose caused by an allergic reaction.
They can be taken as tablets, capsules, nasal sprays or liquids.
Do not use them for more than a week at a time, as using them for endless periods can make your symptoms worse.
Steroid medicines can assist reduce inflammation caused by an allergic reaction.
They’re available as:
Sprays, drops and feeble steroid creams are available without a prescription.
Stronger creams, inhalers and tablets are available on prescription from a GP.
Immunotherapy may be an option for a little number of people with certain severe and persistent allergies who are unable to control their symptoms using the measures above.
The treatment involves being given occasional little doses of the allergen, either as an injection, or as drops or tablets under the tongue, over the course of several years.
The injection can only be performed in a specialist clinic under the supervision of a doctor, as there’s a little risk of a severe reaction.
The drops or tablets can generally be taken at home.
The purpose of treatment is to help your body get used to the allergen so it does not react to it so severely.
This will not necessarily cure your allergy, but it’ll make it milder and mean you can take less medicine.
