Grass allergies are very common and if an individual is allergic to one kind of grass, such as rye grass, he is likely allergic to all grass types due to the cross-pollination. The grass allergy season usually runs its course during May and June but in warmer climates the grass allergy season may be extended or last year-round.

Allergy Symptoms

The most common allergy symptom with a rye grass allergy is sneezing, or what is commonly referred to as hay fever. Along with sneezing, the allergy sufferer will experience congestion, itchy eyes and a runny, itchy nose. Rye grass allergy symptoms tend not to be as strong as symptoms of other allergies but the pollination season is longer and therefore the symptoms will last longer as well.

Cause of Rye Grass Allergy

Allergy to rye grass is caused by the pollen the grass creates in May and June. This pollen is breathed in and causes a reaction in the body that results in sneezing and other allergy symptoms. Some rye grass allergy sufferers will show allergy symptoms in the later summer months as well. However, those allergy symptoms are more likely to be related to a mold allergy as mold spores are lifted into the air during mowing in the dryer summer months.

Methods to Cope

Unfortunately, grass is not an easy allergy to escape. However, closing your windows while indoors will prevent grass pollen from entering the house and causing allergic reactions. Avoid mowing grass if possible during May and June when grass is pollinating. Don't allow the lawn to grow too tall. Short grass is not able to produce as much pollen.


The symptoms of a rye grass allergy can generally be controlled with antihistamines. When selecting an allergy medication, it is important to review the ingredients and choose one that won't cause drowsiness. However, if sleep at night is difficult because of allergies, it might be appropriate to take an allergy medication with a sleep aid to assist in getting a full night of rest. Allergy sufferers can get ahead of the rye grass allergy season by taking the medication before the allergy season starts. This will build the level of the drug in the body and create a histamine barrier prior to the allergy season. Always consult a doctor before taking any medications.


Allergies can be annoying and difficult to deal with. However, some allergies are much more serious. Acute allergies to rye grass can cause difficulties breathing and cause the heart to pump faster and harder. These are signs of an acute allergic reaction, and medical treatment should be provided immediately. Very rarely are individuals able to recover from an acute reaction on their own, and trying to do so can be fatal.
