Symptoms for Covid-19. If necessary.

Hi, My father (63 years) got covid19 positive 10days back and after that I have gradually started showing symptoms for the virus for which I started taking antibiotics (amoxycilin) and cough syrup along with betadine gargle, I and my father have no symptoms now and getting fit day-by-day. We have consulted a doctor previously. Now, my mother started picking up the symptoms like Fatigue, sore throat, cough, loss of taste and smell, increased temperature (between 98°F and 99°F) nausea/vomiting tendency and headache. I am trying a consultation because she is aged and I'm worry of if the symptoms gets worsen. Vitals are as follow: Blood pressure: 115/70 (low) SpO2 level: 98 Pulse rate Bpm : between 80 to 95 Looking for any special medication if necessary.
