Your Child’s Medicine At a Glance

Bilachek Syrup is an anti-allergic medicine. It is given to children to treat a wide range of symptoms associated with allergic conditions such as hay fever, urticaria (hives), conjunctivitis (red, itchy eye), and the common cold. These symptoms may include watery eyes, runny nose, sneezing, and itching.

Give Bilachek Syrup to your child by mouth, one hour before or two hours after food. Avoid giving it with food or fruit juices as this will decrease the absorption of the medicine. Adhere to the dose, time, and way prescribed by the doctor as that depends on the severity of the allergic condition, your child’s age, and body weight. If your child vomits within 30 minutes of taking this medicine, let the child calm down and give the same dose again. However, do not repeat the dose if it is already time for the next dose.

It is usually given once a day. The allergic symptoms may subside after your child has taken the initial few doses of Bilachek Syrup. However, in cases of serious allergic conditions, your child may have to continue taking the medicine for a longer duration.

Your child may experience minor and temporary side effects like nausea, vomiting, dry mouth, dizziness, sleepiness, and headache after the intake of this medicine. Usually, these symptoms subside once your child’s body adapts to the medicine. However, in case of prolonged or bothersome events, it would be best to consult your child’s doctor without any delay.

Inform your child’s doctor if your child is on any medical regime or is allergic to any medicine, product, or food. Make sure the doctor knows if your child has or had any heart, liver, or kidney problems or was born prematurely. Any history regarding bowel obstruction, malnutrition, weight-related issues, and thyroid problems should also be well indicated to the doctor to avoid any complications in the treatment. All this information will help your child’s doctor make dose alterations and plan your child’s overall treatment better.
