Yellow promethazine cough syrup?

A yellow promethazine cough syrup is usually a formulation that contains promethazine (an antihistamine) plus another cough suppressant like codeine or dextromethorphan, or sometimes promethazine alone with a different ingredient. The yellow color comes from the dye in the medicine, not from a special kind of promethazine.

Important safety notes:
- Promethazine with codeine (a common combo) is a prescription medicine in many places. It can be effective for coughs but can cause drowsiness, dizziness, and slowed breathing, especially with alcohol or other sedatives.
- It can be dangerous in children. In many regions, codeine-containing cough syrups are not recommended for children under 6, and promethazine-containing products have special cautions for kids and certain health conditions.
- Don’t use if you’re allergic to promethazine or any dye/additives, if you have certain breathing problems, glaucoma, or certain other medical conditions unless a doctor confirms it’s safe.
- Pregnant or breastfeeding individuals should consult a clinician before using promethazine-containing medicines.
- Do not exceed the prescribed dose, and avoid driving or operating heavy machinery until you know how it affects you.

If you have the bottle, the best way to identify it is to read the label for:
- Active ingredients (e.g., promethazine HCl with codeine, promethazine HCl with dextromethorphan, etc.)
- Concentration (mg per 5 mL, etc.)
- NDC or manufacturer name

If you’d like, tell me the exact active ingredients listed on the label or share the brand name and country, and I can help identify it and give more specific safety info. Also, tell me your age and any other meds you’re taking, and I can tailor safety considerations. If you’re asking because you or someone else is using it now, and you’re worried about side effects or dosing, let me know that as well.
