Promethazine Addiction And Abuse
Understanding PromethazineÂ
Promethazine (Phenergan) is an Antihistamine derived from phenothiazine. It is available as a tablet, solution, and rectal suppository. In tablet form, it can be cut or crushed and taken with or without food.Â
How Promethazine WorksÂ
Promethazine works by blocking histamine during an allergic reaction. Histamine is an organic compound released during a local immune response. Promethazine also reduces the number of signals shot off by the brain, which induces vomiting. When in tablet form, it can interact with other medications.Â
Introduction of the Antihistamine to other substances changes its common effects. This change makes the Antihistamine popular among medical professionals during combination therapy. For example, when mixed with Opioids like Meperidine, Promethazine can help as a pain reliever. If taken with Phenobarbital, a Barbiturate, Promethazine can cause severe drowsiness.Â
Promethazine is used for conditions like:
- Allergies (watery eyes, redness, rashes)
- Motion sicknessÂ
- Common cold symptoms (sneezing, cough, and runny nose)
- NauseaÂ
- Vomiting
- Anxiety before surgeryÂ
- Pain after surgery
- Insomnia
Though the Antihistamine helps control specific symptoms, it does not treat them. Promethazine also does not speed up recovery. To learn how the drug interacts with other prescriptions, always consult a healthcare professional.

Effects And Abuse
Promethazine affects the body’s ability to regulate inflammation, alertness, and pain control. By preventing the release of histamine, it causes sleepiness and deep relaxation. This drug increases the skin’s sensitivity to the sun and increases the risk of sunburn.Â
When abused, Promethazine creates several negative effects like:
- Changes in blood pressure
- Skin reactions/sun sensitivity
- Jaundice
- Hallucinations or confusion
- Seizures
- Abnormal heart rhythm
- Blurred or double vision
- Insomnia
- Dry mouth
- Nightmares
- Ear ringing
- Organ failure
- Bruising
- Breathing problemsÂ
- Overexcitement
- Abnormal movements
Though dangerous on its own, the Antihistamine can be lethal when combined with other illicit drugs.Â
Promethazine abuse is frequent in patients struggling with coexisting addictions. In a recent study published by the National Library of Medicine, researchers discovered compelling evidence of Promethazine’s non-medical use. One-quarter of the patients in the study who were using Methadone were also taking Promethazine. Out of the sample of Methadone users, only 15% had an active Promethazine prescription.Â

Promethazine, Opioids, And Abuse
Opioids, Promethazine, and abuse are highly correlated. Methadone use for Opioid addiction treatment is linked to Promethazine abuse. The Antihistamine strengthens the Opioid “high.” The enhancing ability makes the drug popular among people with a substance use disorder. Promethazine abuse is common among injection drug users, patients with chronic pain, and at-risk teenagers. Sadly, people without prior drug disorders are becoming addicted to Promethazine as well.Â
Opioid Epidemic
The rise of the Opioid epidemic began in the 1990s and continues today. In 2016, about 11.5 million Americans were misusing prescription Opioids. Almost 450,000 people have died due to this epidemic.Â
The fight against the Opioid epidemic is growing. Yet medical professionals prescribed the drug to 191 million Americans in 2017. These individuals are usually non-experienced drug users who run a huge risk of becoming addicts. Prescription Opioids can make anyone addicted to them. One in 4 patients receiving long-term Opioid therapy struggles with Opioid addiction.Â
Once addicted, it can be hard to stop, and many turn to rehab. While in recovery for Opioid addiction, a popular method used to to treat patients is tapering with Methadone. These tapering treatments help individuals wean off Opioids slowly. They do not, however, provide the intense high some patients want. To feel that surge again, many turn to Promethazine; the addiction cycle continues.
