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 South Dakota.

  • Check daily pollen count: Keep an eye on pollen levels to see how high they are in South Dakota 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 in South Dakota. Evening hours will be the best time to go outside during the South Dakota allergy season.
  • Trim trees, mow the lawn, and pull weeds: By keeping up with your yard upkeep, you can reduce the amount of pollen released around your home. You can do this by trimming tree branches, grass short, and your lawn free of weeds.
  • Wear a mask outdoors: Wearing a dust mask when you go outside in South Dakota can help prevent pollen from getting into your airways.
  • 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.
  • Keep windows closed: 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 South Dakota.
  • Install a HEPA filter: Installing a HEPA filter on your A/C can help reduce the pollen levels circulating in your home.


Over-the-counter (OTC) medications are widely available in South Dakota, and they provide temporary relief from your allergy symptoms. However, because they are a short-term solution, they may not provide enough relief from your seasonal allergies. Instead, you can look into allergy treatments that will provide long-term relief.

Sublingual Immunotherapy

Sublingual immunotherapy is the best solution if you want lifelong relief from your seasonal allergies in South Dakota. 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. Sublingual immunotherapy is just as effective as allergy shots, but it can also be taken from the comfort of your home.
