Doff That Cough!: Something's going on here. First, just don't take any more of that stuff. There are other ways to beat a cough. I assume you're taking this for a cough, right?? Try a steamy shower and/or steam from a tea pot. Try a teaspoon of honey. Try one or two capsules of Benadryl (diphenhydramine). But if nothing works go see a doctor. They could try therapy you couldn't do at home, like a nebulizer or other medications, etc ...Read more

Is it safe to take promethazine with codeine syrup, mucinex DM, and the nasal spray fluticasone propionate?

Too many: While fluticasone is fine, you are mixing codeine and Mucinex DM (not just Mucinex) which also contains an opiate. Throw in promethazine and you may end up getting too much sedating effect. ...Read more

What does promethazine dm do to the body?

What does promethazine dm do to the body?

Drugs: Promethazine is an antihistamine and increases the viscosity of your mucus secretions and makes you tired. The DM stands for dextromethorphan which is a synthetic narcotic which acts on the CTZ (central triggering zone) in the brain stem to turn off cough. It reduces coughing but doesn't address the central problem of why you're coughing, the presence of the mucus. ...Read more

Can I take promethazine Dm and Nyquil together?

NyQuil: NyQuil contains antihistamines, acetaminophen, a cough suppressant and alcohol. Promethazine is an antihistamine used to relieve vomiting and motion sickness. The combination could cause severe sedation, seizures, drowsiness, dizziness, blurred vision, and dry mouth. I would avoid taking both NyQuill and promethazine. ...Read more

Can I take mucinex DMV and 5 hours later take promethazine dm?

No: Dextromethorphan has never been shown in studies to relieve any symptom of colds, flu, allergies, bronchitis or pneumonia, including cough, and can be dangerous in high doses. If you have thick mucous, use PLAIN guafenesin (Mucinex). If you have nausea or a cough use PLAIN phenergan, or (for cough) phenergan + codeine or hydrocodone (but you will need an rx for phenergan + anything). ...Read more

Promethazine: Hi P Cruz ~ promethazine causing vomiting is not an unusual symptom. Trash it ! Its not necessary to use a cough med at all. If you are wheezing we can prescribe an inhaler like albuterol and steam inhalations will help to break up mucus. Thats all you need for bronchitis. If you MUST take a cough med use ROBITUSSIN (guaifenesin) thanks ...Read more

What is so bad about drinking alcohol while on promethazine dm? No additional details needed

What is so bad about drinking alcohol while on promethazine dm? No additional details needed

Drug interactions: Would need to know why you are on Promethazine for give any kind of rational answer, but alcohol increases the activity of Promethazine and vice versa; in other words there is more toxicity with both drugs together than just adding up the toxicity of the two separately. Driving on that combination would be particularly dangerous. How much alcohol? A little, not much; a lot, a bunch of problems. ...Read more

My phlegm type cough is kicking up again and I was wondering if it was safe to take my promethazine DM while on suboxone?

My phlegm type cough is kicking up again and I was wondering if it was safe to take my promethazine DM while on suboxone?

Talk to provider: antihistamines have significant interactions with opioids, including buprenorphine, and may cause excessive sedation. There is nothing magic about Promethazine as a cough suppressant, and you could probably get the same or similar effect just using plain Robitussin DM, and leaving antihistamines out of it, particularly phenergan, (promethazine) which really is a drug of abuse when combined with methadone. ...Read more
