There are home remedies you can try first. These treatments may ease congestion related symptoms and help your allergy cough.
1. Saline: Rinsing your nasal passages regularly with saline helps to keep them clear of irritants. You can buy sprays at the pharmacy. Just remember to keep the nozzle clean or it could increase your risk of infection.
2. Steam: Water vapor can loosen mucus. And that may ease coughing caused by allergies. Take a long hot shower. Or put a towel over your head and breath in the steam from a bowl of recently boiled water. Just don’t get too close as it can scald.A humidifier puts more moisture in the air and that can soothe a sore throat and dry cough.
3. Throat soothers: Other ways to help your allergy cough include sucking on throat lozenges or hard candies. There’s no evidence that one is more effective than the other. Water with honey and lemon can be soothing. Or take a spoonful of honey (not for children under one); studies suggest it may be as effective at stopping a cough as most over-the-counter medications.
