Allergy Symptom Relief and Treatment

Allergies can feel difficult to manage, but there are several different methods you can try out to decrease or eliminate your allergy symptoms.

Limit Exposure

An effective method of decreasing your symptoms is limiting your exposure to the allergens that are triggering your allergies. While pollen can be difficult to avoid, there are ways that you can decrease your exposure to pollen in Washington, DC.

  • Check daily pollen count: Keep an eye on pollen levels to see how high they are in Washington, DC for the day. If it’s a high pollen count, try limiting your time outside that day. Pollen tends to be at its highest in the morning and afternoon. Evening hours will be the best time to go outside during the Washington, DC allergy season.
  • Trim trees, mow the lawn, and pull weeds: By keeping tree branches trimmed, grass short, and your lawn free of weeds, you can reduce the pollen that will be released directly around your home in Washington, DC.
  • Wear a mask outdoors: Wearing a dust mask when you go outside in Washington, DC can help prevent pollen from getting in your airways. Another tip is to wear sunglasses if you can to prevent anything from getting into your eyes.
  • Clean regularly: Pollen can easily get in your home and on you and your clothes. Be sure to clean your house and do laundry frequently. Also, make sure to shower after being outdoors to wash off any pollen. If you have any pets, make sure to bathe them after they’ve been outdoors.
  • Close your windows: Opening your windows will allow for more pollen to get into your home. If you can, keep your windows closed and run your A/C instead for the duration of the allergy season in Washington, DC. If you are in the car, try to run the A/C instead of having your windows open.


Over-the-counter (OTC) medications are widely available in Washington, DC, and they provide short-term relief from your allergy symptoms. If you find that antihistamines, nasal sprays, and eye drops don’t provide enough relief from your seasonal allergies, you can look into allergy treatments that will provide long-term relief instead of just masking your symptoms.

Sublingual Immunotherapy

If you want lifelong relief from your seasonal allergies in Washington, DC, sublingual immunotherapy is the best solution. Sublingual immunotherapy involves exposing your immune system to small doses of the allergens that trigger your allergies. Through this exposure, your body becomes desensitized to your allergies, providing long-term relief.
