It may be found alone in some cough preparations or in combination with other medications. It may be combined with guaifenesin, an expectorant that will loosen chest secretions, an antihistamine or a decongestant. These medications may be given every four to six hours with no more than six doses in a 24-hour period. Using a combination preparation is good if your child has multiple symptoms. However, if your child has only one symptom, try to find a preparation that contains only the medication needed to treat the symptom.
Generic preparations are the same as the brand-name preparations.
However, there is often a taste difference with the brand names having the better taste. Just ask your primary care physician or pharmacist.
