If you use hydrocodone while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks.

How should I take guaifenesin, hydrocodone, and pseudoephedrine?
Follow the directions on your prescription label and read all medication guides. Never use this medicine in larger amounts, or for longer than prescribed. Take this medicine only until your symptoms clear up.
Never share opioid medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it. Selling or giving away opioid medicine is against the law.
Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Call your doctor if your symptoms do not improve after 7 days of treatment, or if you have a fever with a headache, cough, or skin rash.
If you need surgery or medical tests, tell the surgeon or doctor ahead of time if you have taken a cough or cold medicine within the past few days.
Store at room temperature away from moisture, heat, and light. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.
Do not keep leftover medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Read and carefully follow the instructions provided with this medicine about how to safely dispose of any unused portion.
What happens if I miss a dose?
Since this medicine is used when needed, you may not be on a dosing schedule. Skip any missed dose if it's almost time for your next dose. Do not use two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of hydrocodone can be fatal.
Overdose symptoms may include extreme drowsiness, feeling weak or limp, cold and clammy skin, breathing problems, fast or slow heartbeats, confusion, hallucinations, slurred speech, blue lips, slow breathing, fainting, or breathing that stops.
What should I avoid while taking guaifenesin, hydrocodone, and pseudoephedrine?

Ask a doctor or pharmacist before using other cough or cold medicines that may contain similar ingredients.
