Here's a clear overview about medication dosages for adults treating an upper respiratory tract infection (URTI):

• Understanding Upper Respiratory Tract Infection (URTI)
  URTIs affect the nose, throat, and sinuses, commonly caused by viruses like the common cold or sometimes bacteria.

• General Approach to Treatment
  Most URTIs are viral and improve on their own. Treatment focuses on relieving symptoms rather than curing the infection.

• Common Medications Used

  • Over-the-counter options: Analgesics such as paracetamol (acetaminophen) help reduce fever and pain. Decongestants can relieve nasal congestion.
  • Antibiotics: Only appropriate if a bacterial infection is confirmed or strongly suspected, as they do not work against viruses.

• Dosage Guidelines for Adults

  • Paracetamol: Typically 500 mg to 1000 mg every 4 to 6 hours, not exceeding 4 grams per day.
  • Decongestants: Follow package instructions carefully; usually limited to a few days to avoid rebound congestion.
  • Antibiotics: Dosage varies by the specific drug prescribed; always follow the doctor’s instructions precisely.
    It is crucial to follow the medication label or your doctor’s guidance and not self-medicate, especially with antibiotics.

• When to Seek Medical Advice

  • Symptoms lasting more than 10 days, worsening symptoms, high fever, difficulty breathing, or severe pain require evaluation.
  • Avoid unnecessary antibiotic use to prevent antibiotic resistance.

• Additional Supportive Measures
  Rest, stay well-hydrated, use saline nasal sprays, and humidify the air to ease symptoms.

• Relevant Medical Specialties
  General practitioners and ear, nose, and throat (ENT) specialists are best suited to diagnose and manage URTIs.

If you have symptoms or questions about treatment, please consult a general practitioner or an ENT specialist for personalized advice.
