Answer: The drug diphenhydramine is prescribed for the following conditions:
A) Urticaria
Diphenhydramine is commonly used to treat urticaria, which is a skin condition characterized by itchy, red, and raised welts. It works by blocking the histamine receptors in the body, thereby reducing the symptoms of urticaria.
B) Vasomotor rhinitis
Diphenhydramine can also be prescribed for vasomotor rhinitis, which is a condition that causes nasal congestion, sneezing, and a runny nose. By blocking the histamine receptors in the nasal passages, diphenhydramine helps alleviate these symptoms.
E) Angioedema
Angioedema is a condition characterized by the swelling of the deeper layers of the skin, often in the face, lips, tongue, or throat. Diphenhydramine can be used to manage angioedema by reducing the swelling and relieving associated symptoms.
C) Productive cough and D) Motion sickness
However, diphenhydramine is not typically prescribed for productive cough or motion sickness. It does have some antitussive (cough-suppressing) properties, but it is not commonly used for treating productive cough. Additionally, while diphenhydramine can have sedative effects, it is not the primary medication used for motion sickness.
To summarize, diphenhydramine is prescribed for urticaria, vasomotor rhinitis, and angioedema, but it is not commonly prescribed for productive cough or motion sickness.
