Tussionex (Chlorpheniramine & Hydrocodone ) Syrup
Do not take Tussionex more often than prescribed. An overdose of Tussionex can cause life-threatening side effects. To be sure you get the correct dose, measure this medicine carefully with a marked measuring spoon or syringe, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
Before you take Tussionex, tell your doctor if you have asthma or another breathing disorder, a history of head injury or brain tumor, stomach or intestinal problems, liver or kidney disease, glaucoma, urination problems or an enlarged prostate, Addison’s disease, or underactive thyroid.
