Leukotriene inhibitors

A leukotriene inhibitor is a prescription medication that blocks symptom-causing chemicals called leukotrienes. This oral medication relieves allergy signs and symptoms including nasal congestion, runny nose and sneezing. Only one type of this drug, montelukast (Singulair), is approved for treating hay fever.

In some people, leukotriene inhibitors can cause psychological symptoms such as irritability, anxiousness, insomnia, hallucinations, aggression, depression, and suicidal thinking or behavior.

Allergen immunotherapy

Immunotherapy is carefully timed and gradually increased exposure to allergens, particularly those that are difficult to avoid, such as pollens, dust mites and molds. The goal is to train the body's immune system not to react to these allergens.

Immunotherapy might be used when other treatments aren't effective or tolerated. It might help prevent the development of asthma in some people.

Shots

Immunotherapy may be administered as a series of injections, usually one or two times a week for three to six months. This is followed by a series of less frequent maintenance shots that usually continue for three to five years.

Side effects might include irritation at the injection site and allergy symptoms such as sneezing, congestion or hives. Rarely, allergy shots can cause anaphylaxis, a sudden life-threatening reaction that causes swelling in the throat, difficulty breathing, and other signs and symptoms.

Sublingual immunotherapy (SLIT)

With this type of immunotherapy, you place an allergen-based tablet under your tongue (sublingual) and allow it to be absorbed. This daily treatment has been shown to reduce runny nose, congestion, eye irritation and other symptoms associated with hay fever. It also improves asthma symptoms and may prevent the development of asthma.

SLIT tablets contain extracts from pollens of different types of grass, including the following:

  • Short ragweed (Ragwitek)
  • Sweet vernal, orchard, perennial rye, Timothy and Kentucky blue grass (Oralair)
  • Timothy grass (Grastek)

Emergency epinephrine shots

Epinephrine shots are used to treat anaphylaxis, a sudden, life-threatening reaction. The drug is administered with a self-injecting syringe and needle device (autoinjector). You might need to carry two autoinjectors and wear an alert bracelet if you're likely to have a severe allergic reaction to a certain food, such as peanuts, or if you're allergic to bee or wasp venom.

A second injection is often needed. Therefore, it's important to call 911 or get immediate emergency medical care.

Your health care provider will train you on how to use an epinephrine autoinjector. It is important to get the type that your doctor prescribed, as the method for injection may differ slightly for each brand. Also, be sure to replace your emergency epinephrine before the expiration date.

Examples of these medications include:

  • Adrenaclick
  • Auvi-Q
  • EpiPen
  • EpiPen Jr.

Get your doctor's advice

Work with your doctor to choose the most effective allergy medications and avoid problems. Even over-the-counter allergy medications have side effects, and some allergy medications can cause problems when combined with other medications.

It's especially important to talk to your doctor about taking allergy medications in the following circumstances:

  • You're pregnant or breast-feeding.
  • You have a chronic health condition, such as diabetes, glaucoma, osteoporosis or high blood pressure.
  • You're taking other medications, including herbal supplements.
  • You're treating allergies in a child. Children need different doses of medication or different medications from adults.
  • You're treating allergies in an older adult. Some allergy medications can cause confusion, urinary tract symptoms or other side effects in older adults.
  • You're already taking an allergy medication that isn't working. Bring the medication with you in its original bottle or package when you see your doctor.

Keep track of your symptoms, when you use your medications and how much you use. This will help your doctor figure out what works best. You might need to try a few medications to determine which are most effective and have the least bothersome side effects for you.
