It’s sad when you’re not using any illegal substance and still fail a drug test because of medication you need. Promethazine is not controlled meds, and it’s using is not illegal. However, it could lead to problems with a drug test. Can they detect Promethazine on a drug test? How long it lasts in the system? How to flush Promethazine out of the system? These questions we have to answer today and while you have a time for checking yourself
What’s Promethazine and why it can show up in a drug test?
Promethazine is a first-generation antihistamine drug. It’s called “phenothiazine” and administered in the cases of chronic pain, postoperative nausea and vomiting. Sometimes it used for the treatment of allergy or symptoms of a cold.
Labs do not detect Promethazine as a part of a standard drug screen. However, if Promethazine is combined, for example, with Codeine in a cough syrup, you can fail the test for Opiates because of Codeine presence, not for Promethazine.
Some studies reported that Promethazine could cause the false positive results for Amphetamines and Methamphetamines. In any case, it’s better to make self-testing and clean then fail because of such simple thing as a cough syrup.
How long does Promethazine stay in the system?
This drug is water soluble and leaves the body quickly enough. It appears in the bloodstream in 20 minutes if taken orally, and the effects last 4-6 hrs, in some persons hold for 12 hrs.
On average, after 2-5 days it’s no traces of the drug in the system. However, the time frames as for other drugs may vary. They depend on the age, health condition, dose, frequency of usage and the way of administration.
Promethazine with Codeine can stay in the system for 8-12 days, and even longer. So if you’ve taken the cough syrup with these components, wait for two weeks for natural cleansing, or use solution that helps you become clean from Opiates faster.
What about the side effects and drug’s interactions?
Promethazine as any other drug has unwanted effects – from the light ones like a little weakness or sweating to potentially fatal as irregular heart beating, difficult breathing, or convulsions. It’s counted about 50 side effects and unusual reactions while taking Promethazine, so never consume it without doctor’s prescription.
Your doctor also has to inform you both about what side effects could appear and what drugs you have not to combine with Promethazine. Because of it’s sedative effect to central-nervous-system, avoid combinations with alcohol, barbiturates, benzos, opiates, cocaine, tricyclic antidepressants. Ask your doctor first if you’ve taken any of these meds. Interaction can be dangerous to your life.
How to clean the system from Promethazine?
The best thing you can do if worried to get a positive result is stopping using and give your bode a time. Less in a week, you’ll be clean. If, of course, the cough syrup is not your “best friend” for years. If you take Promethazine for a long time and in large doses, be careful- it causes withdrawal syndrome. So it’s better to be under medical control during this time.
Anyway, keep the home test in your pocket and use it, if you take any drug, even “simple” anti-cough or anti-flu remedy.
