Kenalog is not a first line treatment for hay fever and should only be considered when simple measures have proven ineffective. It is recommended to try medications that are available over the counter or from your Pharmacist or General Practitioner in the first instance.

However, if these treatments fail to control the symptoms of hay fever, a Kenalog injection may be beneficial. What makes Kenalog injections unique is that oral steroids are generally only effective for less than 24 hours. Once the injection is administered the effects can last for at least 4 weeks, and for some, can cover a whole hay fever season.

Find out if you can have this treatment:


Around 10% of hay fever sufferers find that readily available treatments, such as over the counter antihistamine tablets and nasal sprays, are ineffective and they continue to struggle to manage their symptoms. As an alternative, sufferers may consider the Kenalog™ corticosteroid injection. Steroids are some of the most powerful anti-inflammatory medications available and they work by suppressing the body's immune response, thereby reducing symptoms.

Kenalog injection contains the active ingredient triamcinolone, which is a type of medicine called a corticosteroid. Corticosteroids are hormones that are produced naturally by the adrenal glands. They have many important functions in the body, including control of inflammatory responses. Triamcinolone reduces inflammation by stopping cells from releasing chemicals that normally help produce immune and allergic responses.

This can help control a wide number of disease states involving excessive inflammation, including severe allergic reactions, inflammation of the lungs in asthma and inflammation of the joints in arthritis, and a proven treatment for hay fever sufferers. You must be over the age of 18 years old and under 70 years old to receive this treatment.
