Diominic DCA Tablet belongs to a class of medication called 'cough and cold medications' primarily used to treat the common cold and allergic symptoms like sneezing watery eyes, or itchy/watery nose and throat. The common cold is a respiratory illness affecting the nose and throat, mostly caused by viruses known as 'rhinovirus.' The virus attacks the body through the mouth, nose, or eyes and spreads quickly through droplets in the air when a person who is sick sneezes, coughs, or talks.

Diominic DCA Tablet is composed of four medicines, namely: Chlorpheniramine (anti-histamine), Phenylephrine (decongestant), Paracetamol (mild analgesic and antipyretic), and Caffeine (a stimulant).  Chlorpheniramine belongs to the class of antihistamines (anti-allergic drugs) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. Phenylephrine helps in shrinking the blood vessels in the nasal passage, thereby reducing the stuffy nose. Paracetamol is an analgesic (relieves pain) and antipyretic (reduces fever) that works by inhibiting the production of certain chemical messengers in the brain known as 'prostaglandins' responsible for pain and fever. Caffeine acts as a common stimulant, which decreases sleepiness caused by Chlorpheniramine and speeds up the action of all the medicines present in Diominic DCA Tablet .

Common cold: The common cold is an infection caused by the virus, mainly known as ‘rhinoviruses’ affecting the nose and throat (upper respiratory tract). Children younger than 6 years are at the most significant risk of colds, but healthy adults can also be affected to have 2-3 colds annually. In most cases, cold symptoms are recovered within a week or ten days. However, symptoms might last longer in people who smoke or are exposed to allergens like pollutants, dust, etc. The common cold symptoms include sneezing, sore throat, cough, congestion, mild body pains, low fever, mild headache, feeling unwell, stuffy, or runny nose. In some cases, the discharge from the nose may become thicker and yellow or green, which is not an indication of bacterial infection.

Allergies: It occurs when foreign elements that cause allergy-causing agents (allergens) attack and invade our body, thereby causing the release of histamines. This chemical messenger 'histamines' causes swelling, inflammation, redness, itchiness, itchy/watery nose, throat, and watery eyes. Allergies generally occur due to chemicals, air pollution, pet danders, dust, pollen hairs, seasonal allergies like hay fever, etc.
