I'm sorry to hear that you're experiencing a high fever of 103°F. Here are some important steps you can take:

• Take fever-reducing medication: You may consider using an antipyretic like paracetamol (acetaminophen) to help lower your fever and relieve discomfort. For example, a medication similar to "99F 650 mg Tablet" can be used as directed by a doctor.
• Stay hydrated: Drink plenty of fluids such as water, herbal teas, or fresh fruit juices to prevent dehydration.
• Rest: Ensure you get adequate rest to help your body fight the infection.
• Keep cool: Use a damp cloth on your forehead or take lukewarm baths to help reduce the fever.

Important:

• If your fever persists for more than 2-3 days, worsens, or is accompanied by symptoms like difficulty breathing, severe headache, rash, persistent vomiting, or confusion, seek immediate medical attention.
• Avoid self-medicating beyond recommended doses and consult a doctor before taking any medication, especially if you have other health conditions or are pregnant.
