Hi, thanks for asking in Healthcare Magic. Weight of the child is important in calculating the required dose. Since you have not mentioned the body weight of your daughter I have given you the dose range. Swich CV is Cefpodoxime. It is an antibiotic given to treat lung infections. The dose in your child is around 8-10 mg/kg body weight in two divided doses. This drug is not responsible for the drowsiness. Calpol P is Paracetamol given to reduce fever. Dose in children between 1 to 3 years is 80 to 160 mg given every fourth hourly. Usually 5 ml of syrup contains 120 mg. Paracetamol does not cause drowsiness. Bricarex A is a mixture of Terbutaline, a bronchodilator, Ambroxol, a mucolytic (breaks the thick mucous plugs that can cause cough) and Guaiphenesin, an expectorant. Guaiphenesin is a plant product. It facilitates the removal of the mucous by increasing the mucociliary function of the bronchus. Drowsiness is not the side effect of these drugs. Laveta M is levocetirizine and Montelukast. Levocetirizine is an antihistamine and Montelukast is a leukotriene antagonist. Both are given to control allergy. Dose of Montelukast is 4 mg and is usually given only once a day. Levocetirizine is a non sedative ( no drowsiness). The non sedative property of this drug is based on the fact that it does not enter brain. However in some individuals it crosses the blood brain barrier and enters brain. If it enters the brain it will certainly cause drowsiness. To reduce drowsiness Laveta M can be given once a day for your daughter instead of twice daily administration. I hope this is useful to you.
