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 Los Angeles.

  • Check daily pollen count: Generally, pollen tends to be highest in the morning and afternoons, making evenings the best time to go outside in Los Angeles. Another tip is to check the Los Angeles pollen forecast and limit outdoor time on high pollen count days.
  • Trim trees, mow the lawn, and pull weeds: Regularly manicuring your yard can reduce the pollen released directly around your home in Los Angeles.
  • Wear a mask outdoors: To prevent pollen from entering your airways, you can wear a dust mask when you go outside in Los Angeles.
  • Clean regularly: Due to the sticky nature of pollen, it is essential to clean your home and do laundry frequently. Similarly, showering after being outdoors will allow you to wash off any pollen.
  • Keep windows closed: Pollen easily enters the home through open windows and doors. Running your A/C and closing windows and doors during allergy season in Los Angeles will effectively combat this.
  • Install a HEPA filter: Installing a HEPA filter on your A/C can help reduce the pollen levels circulating in your home.

Medications

Over-the-counter (OTC) medications are widely available in Los Angeles, and they provide short-term relief from your allergy symptoms. If 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 Los Angeles, 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.

Getting sublingual immunotherapy in Los Angeles is easy and convenient. Sublingual immunotherapy is also just as effective as allergy shots, but it can also be taken from the comfort of your home.
