Norco is one of the most well-known opioid medications prescribed to treat moderate to severe pain.

Its two main ingredients are acetaminophen and hydrocodone. Hydrocodone acts as an opioid pain-relief medication, while acetaminophen is a less potent pain reliever that amplifies the effects of hydrocodone.

As it is often the case with most narcotics, Norco belongs to a group of pain relievers that users often abuse. Uncontrolled dependence on Norco can lead to physical and psychological addiction, overdose, and, in the worst case scenario, death.

Norco Withdrawal Facts

Addiction to Norco can be in effect as quickly as the second week of drug use. After the Norco addict has come to realize the dire problem that they are dealing with and has decided to detox, it is essential that they become familiar with a few facts about withdrawal from Norco.

A sudden halt in Norco intake can be very dangerous and may lead to irreversible health problems, so Norco users are advised to seek professional help when undergoing withdrawal.

What are the Symptoms of Norco Withdrawal?

Withdrawal from Norco can cause a number of symptoms, including flu-like symptoms such as runny nose, muscle aches and pains, nausea, excessive sweating, diarrhea, vomiting, and restlessness.

Other symptoms of Norco withdrawal may include dilated pupils, anxiety or agitation, depression, insomnia, high blood pressure, abdominal cramps, rapid pulse, rapid breathing, and tremors.

How Long Does Norco Withdrawal Last?

The Norco withdrawal timeline will begin within 72 hours after a user’s last dose, and can last for between three weeks and  two months.

Norco withdrawal symptoms are most acute during the first week, and symptoms will likely continue for at least 3 weeks, though with decreased intensity after the first week.

Norco Withdrawal Timeline

24-72 hours of hydrocodone withdrawal – In most cases, it is during the first 72 hours that the withdrawal symptoms reach their peak after the effects of Norco had tapered off.

The most common symptoms are mood changes, respiratory depression, diarrhea, drowsiness, stomach pains, and abnormal skin sensations.

Norco Withdrawal Timeline

Weeks 1 & 2 of hydrocodone withdrawal – According to thorough medical observation and analysis, a Norco addict experiences the most grueling effects of the withdrawal during the very first week.  Symptoms during this phase manifest themselves in the form of irritability, depression, intense craving, and exhaustion. Symptoms during the 2nd week may lessen, but the individual might encounter new discomforts such as insomnia, muscle cramps, and backaches.

Weeks 3 & 4 of hydrocodone withdrawal – Week 3 or 4 might mark a Norco user’s last phase of the withdrawal. At this stage, the two most common symptoms are waves of cravings and psychological dependence, which one can easily overcome with the help of a professional.


Norco withdrawal requires professional medical observation. Quitting Norco without medical care can be risky and may cause irreversible health problems. If left untreated, cold sweats, chills, and severe diarrhea can lead to dehydration, which will only make the process of recovery more difficult for the patient.

Thus, Norco users are highly advised to seek professional help before embarking on their withdrawal journey.
