Hydrocodone can slow or stop your breathing. Never use this medicine in larger amounts, or for longer than prescribed. Do not crush, break, or open an extended-release pill. Swallow it whole to avoid exposure to a potentially fatal dose.
You should not use hydrocodone if you are allergic to it, or if you have:
severe asthma or breathing problems; or
a blockage in your stomach or intestines.
To make sure hydrocodone is safe for you, tell your doctor if you have ever had:
breathing problems, sleep apnea;
a head injury, brain tumor, or seizures;
drug or alcohol addiction, or mental illness;
liver or kidney disease;
problems with your gallbladder, pancreas, or thyroid; or
a heart rhythm disorder called long QT syndrome.
How should I take hydrocodone?
Hydrocodone may be habit-forming, even at regular doses. Follow the directions on your prescription label and read all medication guides. Never use hydrocodone in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of this medicine.
What happens if I miss a dose?
Since hydrocodone is used for pain, you are not likely to miss a dose. Skip any missed dose if it is 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. A hydrocodone overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include severe drowsiness, pinpoint pupils, slow breathing, or no breathing.
What to avoid
Do not drink alcohol. Dangerous side effects or death could occur.
Avoid driving or hazardous activity until you know how hydrocodone will affect you. Dizziness or drowsiness can cause falls, accidents, or severe injuries.
Hydrocodone side effects
Get emergency medical help if you have signs of an allergic reaction to hydrocodone: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Opioid medicine can slow or stop your breathing, and death may occur. A person caring for you should give naloxone and/or seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.
What other drugs will affect hydrocodone?
You may have breathing problems or withdrawal symptoms if you start or stop taking certain other medicines. Tell your doctor if you also use an antibiotic, antifungal medication, heart or blood pressure medication, seizure medication, or medicine to treat HIV or hepatitis C.
