Norco Side Effects

Lightheadedness, drowsiness, and constipation are some of the common side effects reported with Norco. Problems such as nausea or vomiting are often mistaken as signs of an allergic reaction to the medication, but these side effects usually go away with continued use of the drug. Side effects that are potentially serious and require immediate medical attention include irregular breathing, anxiety, and difficulty passing urine.

An Introduction to Norco Side Effects

As with any medicine, Norco^® (hydrocodone/APAP) can cause side effects. However, not everyone who takes the medication will experience side effects. Most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.

(This article covers many, but not all, of the possible side effects with Norco. Your healthcare provider can discuss a more complete list of Norco side effects with you.)

Common Side Effects of Norco

Norco can cause several common bothersome (but usually not dangerous) side effects. These common Norco side effects include, but are not limited to:

Constipation (see Norco and Constipation)
Lightheadedness
Dizziness
Drowsiness
Nausea, with or without vomiting.

Many people consider themselves "allergic" to Norco or other similar medications because they experience nausea and vomiting while taking it. However, this is a common side effect and does not indicate a true allergy. Having nausea or vomiting due to Norco in the past does not mean that you cannot take it in the future.

In many cases, this side effect goes away as a person continues to use Norco. Taking Norco with food may help reduce the risk of nausea and vomiting.
