Biochemdryl Syrup is a cough treatment that combines many medications. Biochemdryl Syrup relieves cough by loosening thick mucus and making it easier to cough out. It also improves the flow of air into and out of your airways. This minimizes the frequency of coughing and helps you feel better. Biochemdryl Syrup also treats allergy symptoms such as watery eyes, sneezing, runny nose, and throat irritation. Along with meds, drink plenty of lukewarm water and gargle with warm salt water to alleviate symptoms.
