You can take cold medicine when you have your period. Cold medicine does not affect the period. During the period, the body’s resistance is weak and it is easy to catch a cold. Once the symptoms of cold appear, you need to take cold medicine for treatment quickly to avoid aggravating the cold or causing lower respiratory tract infection. Adults can be treated with Aminga Flavin Capsules, Vitamin C Yin Qiao Tablets, Sensac, Quick, Sanjiu Cold and Flu Granules, and Cold and Flu Clear Granules, which can effectively relieve nasal congestion and runny nose. If there is a more serious sore throat, you need to drink more water and take anti-inflammatory drugs, such as Pu Di Lan Anti-inflammatory Oral Liquid and Blue Scutellaria Oral Liquid, which have certain anti-viral and anti-bacterial effects and can effectively relieve the symptoms of throat inflammation. If a bacterial infection occurs, there will be an increase in white blood cells in the blood routine, and antibiotics are needed for treatment.
