Is it safe and appropriate to take doxycycline 100 mg, xylometazoline nose drops, Mucomix, Zincovit, and Cyrus for my symptoms of severe tiredness, skin rashes, burning eyes, fever, and a blocked nose, and should I get tested for COVID-19 again even though I already had it 2.5 months ago?
It is highly recommended to get tested for COVID-19 again, as reinfection can occur even after 2.5 months. Regarding your medications, doxycycline is an antibiotic and should only be taken if a doctor confirms a bacterial infection. While xylometazoline, Mucomix, and Zincovit can help support congestion and recovery, your new skin rashes and burning eyes require careful evaluation, as they could be a viral symptom or an allergic reaction. Please consult a healthcare professional before taking these medicines so they can safely examine you and prescribe the right treatment.
