Flu-Lock Syrup belongs to the class of medication called 'cough and cold medications' used to treat symptoms of the common cold and allergies like sneezing, runny/stuffy nose, fever, headache, body pains, congestion, or watery eyes in children. The common cold is a respiratory illness affecting the nose and throat. It is mostly caused by viruses known as 'rhinovirus'. The virus enters the body through the nose, mouth or eyes and spreads easily through droplets in the air when the person who is sick sneezes, coughs or talks.

Flu-Lock Syrup is a combination of two drugs, namely, Phenylephrine hydrochloride (decongestant) and Chlorpheniramine maleate (antihistamine/antiallergic). Phenylephrine hydrochloride belongs to the class of decongestants that work by shrinking the blood vessels in the nasal passage. Thereby providing relief from congestion and decreasing excess mucus production. Chlorpheniramine maleate belongs to the class of antihistamines (anti-allergic drugs) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. It helps relieve symptoms of allergies such as sneezing, running nose, watery eyes, itching, swelling, and nasal congestion.

Flu-Lock Syrup is for paediatric use. Your doctor will recommend how often your child needs to take Flu-Lock Syrup based on his/her medical condition. Flu-Lock Syrup may cause common side effects such as drowsiness, nervousness, headache, dizziness, insomnia (difficulty falling or staying asleep), blurred vision, constipation and dry mouth. Most of these side effects of Flu-Lock Syrup do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

If your child is allergic to Flu-Lock Syrup or any other medicines, please tell your doctor. Please do not give more than the prescribed dose of Flu-Lock Syrup to your child as it may cause adverse effects.

Flu-Lock Syrup contains Phenylephrine hydrochloride and Chlorpheniramine maleate. Phenylephrine hydrochloride is a decongestant that works by contracting and narrowing the blood vessels. Thus, it provides relief from congestion and decreases mucus production. Chlorpheniramine maleate is an antihistamine (anti-allergic drug) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. It helps relieve symptoms of allergies such as sneezing, running nose, watery eyes, itching, swelling, and congestion or stiffness.

Common cold: The common cold is an infection caused by a virus, mainly known as ‘rhinoviruses,’ that affects 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 by having 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 symptoms of the common cold include sneezing, sore throat, cough, congestion, mild body pains, low fever, mild headache, feeling unwell, and 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: These occur 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 and throat, and watery eyes. Allergies generally occur due to chemicals, air pollution, pet dander, dust, pollen hairs, seasonal allergies like hay fever, etc.
