Cough, dizziness, headache and general weakness may be due to fever caused by upper respiratory tract infection. Fever with dizziness, headache and general weakness requires monitoring the body temperature and observing whether the body temperature is higher than normal. If oral treatment with these drugs does not work, you need to seek medical advice and improve blood tests, C-reactive protein, chest X-ray and other related tests to determine what kind of pathogenic bacteria are causing the respiratory tract infection. Common pathogenic bacteria include bacteria, viruses and atypical pathogens. Bacterial infections can be treated with penicillin v potassium tablets, azithromycin, cefixime, etc. Viral infections can be treated with oseltamivir, zanamivir, abirater, etc. Atypical pathogens can be treated with erythromycin, levofloxacin, etc.
