Winter is often a tough season for asthma sufferers, who generally more likely to become sick than those without asthma. It’s important for asthma patients to receive proper care when ill, and a recent study sheds new light on a common treatment that might not be the best course of action for most asthmatics.

A persistent cough that remains after an infection has been treated can last for a month or two. There are several treatments that may offer relief, such as antihistamines or a bronchodilator inhaler.

The flu season is upon us. Like that other season—winter—it can be unpredictable. But the Centers for Disease Control and Prevention (CDC) is doing its best to see that we're informed and as prepared as possible for whatever is in store.

How well does the flu shot work?

Vaccines for seniors

Soaps with added “antibacterial” chemicals are not better at protecting people against infection and illness. The added chemicals may be harmful.

The best time to get an annual flu shot is in mid-October. However, it’s not too late to get the shot in December, since people are still at risk of getting flu for several more months.

Nasal irrigation using a neti pot was more effective than inhaling steam in relieving chronic sinus symptoms in a large randomized study.

New research found that heart failure patients who had a flu shot had a 30% lower risk of hospitalization for cardiovascular disease, 16% lower risk of hospitalization for respiratory infections, and a 4% lower risk of hospitalization in general. 

For years, many kids could skip the traditional flu “shot” — along with the tears — and still be protected by the nasal spray vaccine also known as the LAIV (live attenuated influenza vaccine). But not this year. Studies now show that the nasal vaccine is quite ineffective, and pediatricians are starting to change their flu recommendations from a nose squirt to a shot.

A Spanish clinical trial of 400 people—two-thirds of whom were women—has indicated that waiting to fill an antibiotic prescription may be a good idea for people with sniffles, coughs, sore throats, and other respiratory symptoms.

Researchers recruited volunteers who sought care for respiratory symptoms in primary care clinics throughout Spain. The volunteers were randomly assigned to four equal groups. One was given antibiotics and told to take them immediately. Another was sent home without antibiotics but told to return to the clinic if they hadn't improved after several days. The two remaining groups were told to wait to take antibiotics—one was asked to return to the clinic to get their mediation after three days; the other group was given an antibiotic, but told to take the medication only if their symptoms hadn't improved after five to 10 days.
