There are several precautionary measures that you should take before taking Norco. These include:
avoid taking Norco if you are allergic to hydrocodone and acetaminophen
do not take Norco if you have recently used sedatives, alcohol, other narcotic medicines, or tranquilizers
stay away from using Norco if you have taken MAO inhibitors in the past 14 days
taking Norco with certain other drugs can cause serotonin syndrome
You should avoid using Norco if you have breathing problems, severe asthma, or a blockage in your stomach or intestines.
Norco may not be safe for you if you have ever had conditions such as:
a drug or alcohol addiction
breathing problems, sleep apnea, or breathing stops during sleep
a head injury or seizures
problems with your thyroid, pancreas, or gallbladder
If you are pregnant, you should stay away from Norco because your baby could become dependent on the medicine. Withdrawal symptoms may occur in the baby after birth.
Make sure to consult your doctor before using opioid drugs if you are breastfeeding. You should inform your doctor if you notice severe drowsiness or slow breathing in the nursing baby.
