Do you really have a drug allergy?

Many people believe they have allergies to certain medications, even though they really don't. It could be that they experienced only a drug side effect after taking a particular drug, not a true allergic reaction (which is an immune system response). Unfortunately, inaccurate information can limit treatment options. So it's best to confirm a suspected drug allergy with an allergist. That typically involves getting a simple skin test or taking a very small dose of the medication in question in the presence of a medical team.

The cicadas are here: How's your appetite?

Trillions of cicadas are expected to emerge in the US by the end of June, especially in the Midwest. In many parts of the world insects are considered a low-cost source of calories and protein, but some people still won't want to eat them - and some people shouldn't.

New allergies in adulthood

Contrary to common assumptions, new allergies can emerge well into adulthood. New food allergies are more common than new seasonal ones, and shellfish is the most prominent late-emerging allergen. Women are more likely to develop food allergies in adulthood than men and to grapple with severe food-related anxiety. Some people with childhood allergies, such as those to peanuts or pollen, stop having symptoms when they reach adulthood. People who experience potential new allergy symptoms should see their primary care doctor or an allergist.

Sneezy and dopey? Seasonal allergies and your brain

Allergy season is longer and more intense this year-causing sneezing, and itchy eyes in millions of people. But allergies also affect the brain, causing symptoms like brain fog. Here are some ways to prevent or ease brain fog from allergies.

Get ready for allergy season

Allergy season runs from around March through October. Tree pollen dominates in spring, grass in summer, and ragweed in late summer and early fall. In people with an allergy, pollen exposure can trigger the hallmark allergy symptoms: sneezing, watery eyes, stuffiness, scratchy throat, wheezing, and coughing. There are many ways to manage allergy symptoms, such as using over-the-counter medication, taking allergy shots or oral immunotherapy to help the immune system better tolerate allergens, and reducing one's exposure to pollen.

Simpler way to test for true penicillin allergy

A 2023 study found that an oral penicillin challenge in a doctor's office provides a simple method of determining true penicillin allergy.

Is cheese a healthy source of probiotics?

Some types of cheese, including Swiss and Gouda, are a good source of probiotics, but eat cheese in moderation.

Fall allergen alert

Ragweed pollen and mold spores are common causes of allergies during the fall months. Breathing them into the lungs may cause the body to overreact, leading to classic allergy symptoms of a runny nose, watery eyes, and sneezing.
