Low blood count generally means low white blood cells. Anti-inflammatory drugs generally mean antibiotics. Taking antibiotics and antipyretics for viral colds may cause low white blood cells. Viral colds are upper respiratory tract infections caused by viral infections, which are mainly characterized by nasal congestion, runny nose, sneezing, as well as general malaise, malaise, fever, etc. Routine blood tests may show normal or low white blood cell counts, accompanied by an elevated percentage of lymphocytes. For viral colds, antibiotics are not necessary if there is no secondary bacterial infection. Some antibiotics have side effects that lead to decreased blood counts and bone marrow suppression, which may result in lowered blood counts. If the body temperature is high, over 38.5°C, antipyretic analgesics may be given to reduce fever. Antipyretics, such as acetaminophen, have adverse effects that lead to granulocytopenia and may cause low blood counts. If the cold fever is serious, it is recommended to consult a doctor in time and standardize the use of drugs under the guidance of the doctor to avoid adverse drug reactions.
