What should I do for persistent dry cough?

Persistent, recurrent coughing can significantly interfere with normal daily activities and work performance. However, some patients are unaware of how to treat a dry cough—and may wonder: “What should I do if my dry cough won’t go away?”

What to Do for a Persistent Dry Cough

For dry cough caused by infection, oral anti-inflammatory medications may be prescribed under a physician’s guidance. If the dry cough results from an allergic reaction, antihistamines or other anti-allergic medications are typically recommended. In addition, patients should prioritize adequate rest, maintain a light diet, and drink plenty of water. Herbal infusions—such as honeysuckle, chrysanthemum, or fat-seed (Sterculia lychnophora) tea—can serve as healthy alternatives to plain water and may help alleviate dry cough symptoms. Common causes of dry cough include respiratory tract infections and allergic reactions.

A persistent dry cough is often attributable to chronic pharyngeal inflammation, though allergic conditions—including cough-variant asthma—must also be considered. To support recovery, incorporate vitamin C–rich fruits and vegetables into your daily diet. If inflammation is confirmed as the underlying cause, follow your doctor’s recommendations for anti-inflammatory treatment.

Dry cough is a common symptom experienced by many individuals, warranting increased awareness and proactive self-care in daily life. Diet-wise, patients with dry cough should adhere to a bland, non-irritating diet and strictly avoid spicy, pungent, or stimulating foods, which may exacerbate coughing. On days with heavy smog or poor air quality, it is advisable to limit outdoor exposure; if going outside is unavoidable, wearing a protective mask is essential. Staying well-hydrated helps flush metabolic waste from the body, while consuming fresh fruits and vegetables rich in vitamins—especially vitamin C—can effectively ease dry cough symptoms.
