Hi doctor,

My friend's COVID-19 test is negative. Test says "suggestive COVID-19," and lungs are more than 50% infected. His oxygen levels are normal, and he is constantly monitoring oxygen levels. He is unsure about the medicines given to him and is stuck in a place with not much access to big hospitals or doctors. He is on various medications for a week. His symptoms started two weeks before. We want a second opinion, please. I am attaching his latest test reports and prescriptions herewith.



Welcome to

Thank you for the query. I can understand your concern. The recent HRCT (high resolution computed tomography) of the chest has revealed patchy and sub-segmental ground-glass opacities associated with inter and intralobular septal thickening and architectural distortion distributed in all the lobes of both lungs suggestive of atypical or viral or COVID-19 (coronavirus disease 2109) pneumonia. CO-RADS 5 (COVID-19 reporting and data system) and CT severity score 15 out of 25 and 55% to 60% lung involvement. CO-RADS 5 indicates highly suggestive of COVID-19 pneumonia (attachments removed to protect the patient's identity). CT severity score of 15 out of 25 indicates moderate COVID-19 pneumonia, as below 18 out of 25 indicates the moderate type of COVID-19 pneumonia.

According to the HRCT of the chest, he is now suffering from pneumonia may be due to COVID-19 infections though he tested negative for COVID-19. RT-PCR (reverse transcription-polymerase chain reaction) test may become false negative in few cases. In 2% to 3% cases, the RT-PCR test may be negative. False-negative test results can occur if the sample was not taken at the right time of infection.

According to WHO's (world health organization) recent guidelines, a patient with COVID-19 symptoms or positive findings on his or her HRCT of the chest despite being negative by RT-PCR test is considered as COVID-19 positive patient and should be treated according to the symptoms of COVID-19 infections. So, he should take some medications according to the present symptoms. As he has pneumonia, most probably due to a COVID-19 infection, he may take antiviral medications to reduce the viral load. He may also take broad-spectrum antibiotics to prevent any secondary infections, Dexamethasone for protecting the lungs from further damage, Levosalbutamol, antihistamines, etc.

Take care. I hope I have answered your question. Let me know if I can assist you further.

Hi doctor,

Thanks for the reply.

Could you give us the exact dosage, frequency, and number of days for the medicines you suggested, Dexamethasone, Levosalbutamol, and antihistamines? I appreciate any help you can provide.



Welcome back to

Thanks for joining again. I suggest the following,

  • Tablet Fabiflu (Favipiravir) 400 mg three tablets thrice daily on day 1. Two tablets twice daily from day 2 to day 10.
  • Tablet Azee (Azithromycin) 500 mg one tablet one at night for ten days.
  • Tablet Allegra (Fexofenadine) 120 mg one tablet once at night for ten days.
  • Tablet Singulair (Montelukast) 10 mg one tablet once at night for 15 to 30 days.
  • Tablet Dexamethasone 4 mg one tablet twice daily after food for ten days.
  • Tablet Levolin (Levosalbutamol) 1 mg one tablet twice daily for 15 to 30 days.

Monitor your oxygen saturation level routinely. If oxygen saturation level declines below 90%, he can get himself admitted into the hospital for oxygen inhalation therapy.

In case of any other query, knock me.
