What is a ragweed allergy

There’s no point in waiting until you’re miserable to take allergy meds, especially if you desire to hold up your outdoor workouts.

In fact, allergists recommend you start taking meds a couple weeks before allergy season arrives, or, at the latest, take them the moment you start having symptoms, says Dr. Parikh. Taking them early can stop an immune system freak-out before it happens, lessening the severity of symptoms, he adds. Check out the National Allergy Map to figure out when to start taking meds depending on where you live.

As for which allergy meds to take, if you’re seriously stuffed, start with steroid nasal sprays such as Flonase or Rhinocort, which reduce inflammation-induced stuffiness, says Dr.

Keet. And if you’ve got itching, sneezing, and a runny nose, too, glance for non-sedating antihistamines such as Zyrtec, Xyzal, or Allegra, she adds. Just remember: While OTC allergy meds suppress symptoms, they don’t cure the problem, so they may be less effective if your allergies are worsening, notes Dr. Parikh.

Okay, so when does allergy season 2020 start?

Well, it’s technically *always* allergy season due to year-round offenders such as dust mites, mold, and pet dander, says Purvi Parikh, MD, an allergist and immunologist with Allergy & Asthma Network.

But some allergens–pollens, specifically—are seasonal.

Tree pollen, for example, pops up in the spring (generally in tardy March to April), grass pollen arrives in the tardy spring (around May), weed pollen is most prevalent in the summer (July to August), and ragweed pollen takes over from summer to drop (late August to the first frost), says Dr. Parikh.

And even worse news: Climate change means allergy season begins earlier and lasts longer, adds Corinne Keet, MD, PhD, a professor and allergist at Johns Hopkins University School of Medicine.

To get super-specific, Pollen.com has a National Allergy Map that provides an up-to-date allergy forecast in diverse areas around the country and an Allergy Alert app that gives five-day forecasts with in-depth info on specific allergens, helping you decide if you should stay indoors that day.

Certain areas own also seen a particularly large increase in pollen during allergy season.

In 2019, the New York Times reported on the extreme blankets of pollen that hit North Carolina; Georgia and Chicago also faced especially aggressive allergy seasons too. In Alaska, temperatures are rising so quickly (as in numerous other far northern countries), that the pollen count and season duration are seeing unprecedented growth.

What can I do if my allergy meds aren’t working…or my allergies are getting worse?

If you’re already taking OTC allergy meds (and, you know, keeping your windows closed and washing your face and hair after coming inside), allergy shots, a.k.a.

allergen immunotherapy, make your immune system less reactive to allergens (read: pollen), and for some people, they can even induce a cure, says Dr. Parikh.

“By giving little increasing doses of what you are allergic to, you train the immune system to slowly stop being as allergic,” she says. “This is the best way to address allergies, as it targets the underlying problem and builds your immunity to a specific allergen.”

The downside? Allergy shots are a bit of a time commitment. You’ll need to get them once a week for six to eight months, then once a month for a minimum of two years, says Dr. Parikh. You need to be a little bit patient, too, because it can take about six months to start feeling better (so if you desire protection by March, you’ll probably own to start in September the year before).

But a life without allergies? Sounds worth it to me.

Part Descriptions

LP16973-7 Franseria acanthicarpa
False ragweed is a weed species that capable of inducing hayfever, asthma, and conjunctivitis in sensitive patients. Untrue ragweed grows over most of the continental United States and is a major source of pollen allergy.

Untrue ragweed belongs to the family Asteraceae and some cross-reactivity may happen among members of the family. Copyright Copyright © 2006 Phadia AB.Source: ImmunoCap, Immunoglobulin E

LP16973-7 Franseria acanthicarpa
False ragweed grows almost over every the continental United States. Related species are found in Mexico, Hawaii and Australia. Untrue ragweed is considered to be a major source of pollen allergy in certain areas of the USA where the plant is common.

Asthma, allergic rhinitis and allergic conjunctivitis, similar to sensitisation from other Ragweeds, happen in sensitised individuals.

Symptoms may be elicited either due to sensitisation to this species, or due to cross-reactive mechanisms with other members of the Ragweed genus. Copyright Copyright © 2006 Phadia AB.Source: ImmunoCap, ImmunoCap
