Anti allergy drugs are sometimes called mast cell stabilizers and they nip the allergic reaction in the bud by damping down the activity of the mast cells. This medication can control hay fever eyes and a runny nose, as well as being good for asthma. It is usually taken as eye drops or a nasal spray. Itchy, red and inflamed eyes can be soothed with sodium chromo gyrate eye drops. A new drug, lode amide, acts in a similar way.
Steroids work in much the same way as drugs for asthma by preventing inflammation. Used in a nasal spray they reduce inflammation in the lining of the nose and so prevent a runny nose, a blocked nose and sneezing. They can also help prevent red and itchy eyes. If you suffer from severe hay fever, doctors recommend that you start taking steroids every day just before the start of the hay fever seasons and continue taking them until the end.
Corticosteroids are available as tablets and you can also have a steroid injection. Most decongestants belong to a group of drugs called sympathy mimetic. They work by contracting the blood vessels in the nose, which reduces congestion and makes it easier for you to breathe. They usually come as nasal sprays, with the result that only a tiny amount of the drug enters your blood stream. However, if you overuse the spray, or take decongestant tablets, you may have a few side effects, such as an increased heart rate and trembling. A dry powder inhaler is convenient to carry, easy to use and can provide fast relief from the symptoms of asthma.
