Since your current medications indicate you are pregnant, you must select cough remedies carefully. For a dry cough, dextromethorphan is generally considered safe. For a wet cough, guaifenesin is a suitable option. Avoid multi-symptom cold liquids as they often contain alcohol or decongestants. Natural remedies like steam inhalation, warm saline gargles, and honey in warm water are highly effective and completely safe. Please consult your obstetrician before taking any over-the-counter medication to ensure it is safe for your specific stage of pregnancy.

For fever and body aches, take paracetamol or ibuprofen. For sneezing and a runny nose, an antihistamine like cetirizine is helpful. For a dry cough, use a suppressant containing dextromethorphan; for a productive cough, an expectorant like guaifenesin helps. To support your immune system, supplements like Vitamin C, Vitamin D3, and Zinc can be beneficial. However, the most effective natural remedies are staying well-hydrated, eating nutrient-rich foods, and getting plenty of rest. Please consult a doctor for personalized dosages.

For temporary relief from sinus pressure and headache, you can take Ibuprofen or Acetaminophen. For your throat pain, warm salt-water gargles and throat lozenges work well. For a severe cough, an over-the-counter cough syrup containing dextromethorphan (for dry cough) or guaifenesin (for wet cough) can help. Oral decongestants like pseudoephedrine can ease sinus congestion, but avoid nasal decongestant sprays for more than 3 days. Stay well-hydrated and rest. Since your symptoms are severe, please consult a doctor to get a proper diagnosis and ensure you do not need antibiotics.

For a viral fever, paracetamol is recommended to reduce fever and ease body aches. For nasal and chest congestion, saline nasal sprays, steam inhalation, and generic decongestants like pseudoephedrine or mucolytics like guaifenesin can help clear mucus. Since you have a chest and nasal infection, a doctor must evaluate you to determine if these are viral or secondary bacterial infections. Do not take antibiotics (like amoxicillin) without a prescription, as they do not cure viral infections. Please rest, drink plenty of fluids, and consult a healthcare professional for a proper physical exam and tailored prescription.
