I'm sorry to hear that you're still experiencing a cough after your viral fever. It's quite common for a cough to linger for some days after a viral infection as your respiratory tract recovers.

Here are some helpful points and advice:

• Type of Cough: If your cough is productive (with mucus), an expectorant medicine can help loosen and clear the mucus from your airways.
• Medication Option: A combination expectorant like Ascoril SF, which contains guaiphenesin (to thin mucus), terbutaline (to open airways), and bromhexine (to loosen phlegm), may be beneficial. However, this should be taken only under a doctor's prescription and guidance.
• Watch for Side Effects: Some side effects like nausea, dizziness, or fast heartbeat can occur. If these worsen or persist, consult your doctor promptly.
• When to Seek Medical Care: If your cough worsens, you develop breathlessness, high fever, chest pain, or if the cough lasts more than 3 weeks, please see a pulmonologist (lung specialist) for evaluation.
• Home Care Tips: Stay well hydrated, use warm fluids like herbal teas, avoid irritants like smoke, and rest adequately.

Since your cough follows a recent viral illness, it is important to have a doctor assess you to rule out any secondary infections or complications and to prescribe appropriate treatment.

Please consult a pulmonologist or your primary care doctor for a thorough evaluation and personalized care.
