Yeast beta-glucan for preventing colds in allergic rhinitis
Part of Infections, Lungs & breathing clinical trials.
This study tests whether a supplement made from yeast beta-glucan can help prevent upper respiratory infections, like colds, in people with persistent allergic rhinitis (year-round nasal allergy symptoms). It may help reduce the number of colds you get.
Summary written for real people, not researchers, by Clin2.

This trial tests if arbidol, an antiviral medicine, can safely treat allergic rhinitis (hay fever). It might help if your nasal symptoms like sneezing or stuffiness are moderate to severe.
This trial tests if a daily probiotic (Lacticaseibacillus rhamnosus CRL1505) can help prevent upper respiratory infections (like colds and sore throats) in healthy children ages 3 to 12. If your child often gets sick, this supplement might reduce how often they catch a cold.
This study tests whether a daily probiotic (a type of beneficial bacteria) can help ease allergy symptoms like sneezing and a runny nose in children. If your child has allergies, this may offer a natural way to feel better.
