It’s common to have a dry cough and sore throat at the same time, as both can be triggered by environmental irritants or conditions such as allergies or infections. Most of the time, symptoms improve with a combination of home remedies and over-the-counter (OTC) medications. Persistent or recurrent dry cough and sore throat should be evaluated by a physician.
Hydrate and Soothe
A dry cough and sore throat could be caused by dehydration, so the first step in alleviating these symptoms is to drink more fluids. Water may be best, but diluted juices and broth will also help.
Sucking on ice chips can numb a sore throat and temporarily make you feel better. Throat lozenges or hard candy can also help soothe a sore throat. Due to the risk of choking, popsicles are a safer alternative in young children.
Don't underestimate the importance of staying hydrated, as this will keep mucous membranes from drying out. Mucus traps bacteria and other irritants, so drinking enough fluids keeps the mucus from drying out or getting too thick, improving your body's immune response.
Place a humidifier in your room. The tiny droplets of water a humidifier introduces into the air moisturizes your airways and makes breathing easier.
Take a long, hot shower. This can have the same benefit as a humidifier, adding moisture to your throat and airways, improving your symptoms.
Drink warm beverages and inhale the steam in between sips. Tea with added honey may be particularly soothing to the throat.
Sore throat pain can also be relieved with ibuprofen, aleve or acetaminophen. Follow the label directions regarding the dose and frequency of use.
Another option is to try a salt water gargle. According to the Centers for Disease Control and Prevention (CDC), gargling with a solution of 1 cup warm water mixed with 1 teaspoon salt can help soothe the throat.
You may also try OTC cough suppressants. Also known as antitussives, products that contain the cough suppressant dextromethorphan include Triaminic Cold and Cough, Robitussin Cough, Vicks 44 Cough and Cold. Follow label directions for dosing. If you are under a doctor's care for any medical conditions or if you take prescription medications, ask your doctor or pharmacist about best options for cough remedies.
If you have any prescription medications to treat allergies or asthma, use them as directed to help control your symptoms. Also, get plenty of rest, as this plays an important role in the overall recovery.
