F0 quickly took antibiotics to prevent the virus from spreading to the lungs

Colonel, Doctor Nguyen Huy Hoang, Vietnam Hyperbaric Oxygen Center Tropical Center Russia, Ministry of National Defense Coughing when infected with Covid-19 is basically the body’s protective response to expel pathogens from the respiratory tract. However, if the cough is so severe that it causes fatigue and difficulty sleeping, the patient needs to be hospitalized.

According to Dr. Hoang, there are 2 types of dry cough and cough with phlegm, the treatment will be different. If a dry cough is often caused by a viral infection that causes respiratory tract irritation, F0 can use cough suppressants. If coughing up phlegm is often caused by a chronic respiratory disease or bacterial infection, it’s best not to use a cough suppressant but an expectorant.

In fact, many F0 who cough a lot, rush to use antibiotics to prevent the virus from spreading to the lungs. In this case, MSc Nguyen Thu Huong, Head of Covid-19 Anti-epidemic Unit, Thanh Nhan Hospital warning F0 home treatment should not abuse antibiotics. These are medications that are prescribed and recommended by doctors.

According to Dr. Huong, after the examination, if there are signs of infection, F0 will use antibiotics. “Antibiotics are a double-edged sword, if used in the wrong way, both are ineffective and can cause allergies, damage to liver enzymes and kidney function,” said dr.

To find out whether there is lung damage or not, the patient needs to go to a medical facility for an examination and a chest CT scan, not using antibiotics indiscriminately.

Doctor Huong suggested if a patient has a negative PCR test but continues to have lung damage, they need to be hospitalized for further treatment.

Doctor Nguyen Huy Hoang said antibiotics were not effective against viruses in general and SARS-CoV-2 in particular.

According to doctors, antibiotics are used to prevent and treat bacterial superinfections (tonsillitis, bronchiolitis, sinusitis…). But in fact, many F0 are in a hurry to use 2 antibiotics to prevent infection, Dr. Hoang stressed that this was a serious mistake!

According to doctors, with F0s with multiple underlying diseases, inherently poor resistance may be at risk for bacterial superinfection. However, it is not recommended to use up to 2 types for prophylaxis, only 1 prophylactic antibiotic is sufficient.

“Even some people, even without the above risks, still follow each other’s prescriptions, taking up to 2 strong antibiotics at the same time, while there is no sign of infection,” said Dr Hoang well.

According to analysts, there are many types of antibiotics, but currently there are 3 main groups of oral drugs.

– Marcolide group: erythromycin, azithromycin, clarithromycin …

– Beta-lactam group: amoxicillin/clavulanate, amoxicillin/sulbactam, cephalexin, ceforuxim, cefixime, cefpodoxime…

– Quinolones: ciprofloxacin, levofloxacin…

“Abuse of antibiotics is not life threatening, but it will burden the liver and kidneys, while the body is exhausted from the attack of the virus. In addition, if used inappropriately will cause bacteria to become resistant to the drug. Later, if you get an infection, the antibiotics won’t work anymore,” Doctor Hoang suggested that patients taking antibiotics should consult a doctor.

Doctor Hoang advised people not to rush to take antibiotics when experiencing symptoms of cough and sore throat. Instead, F0 can use honey, herbal cough syrup.

When a prolonged dry cough causes fatigue, sleeplessness, stomach pain, people can take medicine or syrup with alimemazine or diphenhydramine. It is a substance that has an antitussive, anti-allergic, sedative effect. If the disease develops seriously, F0 must immediately notify the medical facility for timely treatment.
