I'm sorry to hear you're experiencing fever, common cold, cough, and headache. These symptoms can be uncomfortable, but there are ways to manage them effectively.

Here are some general self-care steps you can follow:

• Rest: Ensure you get plenty of rest to help your body fight the infection.
• Hydration: Drink plenty of fluids like water, herbal teas, and warm soups to stay hydrated and soothe your throat.
• Nutrition: Eat light, nutritious meals including traditional Indian foods such as dals (lentils), khichdi, and seasonal fruits and vegetables to support your immune system.
• Humidity: Use a humidifier or inhale steam to relieve nasal congestion.
• Avoid irritants: Stay away from smoke, strong perfumes, or dust that can worsen cough or congestion.

Regarding medication:
There is a combination tablet called New Hatric 3 Tablet that contains paracetamol (for fever and pain relief), diphenhydramine (an antihistamine to reduce allergy symptoms), phenylephrine (a decongestant), and caffeine (to enhance paracetamol's effect). This medication can help relieve symptoms like fever, headache, congestion, and runny nose. However, it requires a doctor's prescription and should be taken exactly as prescribed. Avoid exceeding the recommended dose to prevent side effects such as liver damage.

Important precautions:

• If you are pregnant, breastfeeding, or have any allergies, consult a doctor before taking any medication.
• Children under 12 years should not take this tablet.
• If symptoms worsen or persist beyond a few days, or if you experience difficulty breathing, high fever, or severe headache, please seek medical attention promptly.

For personalized advice and appropriate treatment, I recommend consulting a general physician or an internal medicine specialist. If symptoms become severe or you have difficulty breathing, contact emergency services immediately.
