They’ll advise you about taking steps to avoid exposure to the substance you’re allergic to, and can recommend medication to control your symptoms.
The best way to keep your symptoms under control is often to avoid the things you’re allergic to, although this isn’t always practical.
For example, you may be able to help manage:
Medications for mild allergies are available from pharmacies without a prescription, but always ask your pharmacist or doctor 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:
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.
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. Don’t use them for more than a week at a time, as using them for long periods can make your symptoms worse.
Red and itchy skin caused by an allergic reaction can sometimes be treated with over-the-counter creams and lotions, such as:
Steroid medications can help reduce inflammation caused by an allergic reaction. They’re available as:
Sprays, drops and weak steroid creams are available without a prescription. Stronger creams, inhalers and tablets are available on prescription from your doctor.
Immunotherapy may be an option for a small 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 small 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 is a small risk of a severe reaction. The drops or tablets can usually be taken at home.
The aim of treatment is to help your body get used to the allergen so it doesn’t react to it so severely. This won’t necessarily cure your allergy, but it will make it milder and mean you can take less medication.
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 help.
