Phenergan Uses

How Does Phenergan Work?

Phenergan has several different effects in the body and the brain. Many of these effects are probably due to its antihistamine activity, since the drug works by blocking histamine receptors.
Phenergan also belongs to a group of medications known as phenothiazines. Although phenothiazines are usually used as antipsychotic medications, Phenergan has little dopamine-blocking activity. This makes it a weak antipsychotic medication, and it is not used as an antipsychotic.
This medication also blocks acetylcholine receptors, which is probably why it helps to alleviate nausea and motion sickness.

Phenergan Use in Children

Phenergan should not be given to children under the age of two years old, due to the risk of breathing difficulty and death (see Phenergan and Children). It should be noted that nausea and vomiting medications should not be used to treat most cases of vomiting in children and adolescents. Only prolonged cases of vomiting with clear, known causes should be treated with Phenergan.

Is Used for Phenergan Off-Label Reasons?

On occasion, your healthcare provider may recommend this medicine for something other than the uses discussed in this article. For instance, using Phenergan to treat morning sickness would be an off-label uses (see Phenergan and Pregnancy for more information).
Using Phenergan to treat nausea and vomiting related to gastrointestinal illness (such as the "stomach flu") or to treat a cough would also be off-label uses. Although various cough syrups that contain promethazine plus other active ingredients are approved for treating cough, no products that contain just promethazine are approved for this purpose.
