You may experience some common side effects, including drowsiness, dizziness, headache, lightheadedness, blurred vision, upset stomach, nausea, constipation, or dry mouth. If these persist or worsen, consult your healthcare provider. To minimize dizziness and lightheadedness, rise slowly from sitting or lying positions. This medication can thicken mucus in the lungs, making breathing and lung clearing more difficult. Staying hydrated can help alleviate this, unless advised otherwise.

While many individuals do not encounter severe side effects, it is important to be aware of them. Contact your healthcare provider immediately if you experience serious side effects such as sleep apnea, involuntary movements, mental/mood changes, ringing in the ears, tremors, urination difficulties, or weakness. Seek urgent medical attention for severe side effects like persistent nausea/vomiting, easy bruising/bleeding, slow heartbeat, severe abdominal pain, yellowing of eyes/skin, or seizures.

In some cases, codeine transforms into morphine more quickly in the body, raising the risk of significant side effects. Immediate medical help should be sought if you notice slow or shallow breathing, severe drowsiness, difficulty waking, or confusion. Rarely, neuroleptic malignant syndrome (NMS) may occur, which requires urgent care if you experience symptoms such as fever, muscle issues, severe fatigue, confusion, sweating, irregular heartbeat, dark urine, or signs of kidney problems.

Allergic reactions to this medication are rare but can be serious. Seek immediate medical help for symptoms like rash, itching, swelling (particularly of the face/tongue/throat), severe dizziness, or breathing difficulties. If you notice any side effects not listed, contact your healthcare provider.

Certain products can interact with this medication. These include skin-applied antihistamines like diphenhydramine cream, ointment, or spray, as well as Cimetidine, Metoclopramide, Naltrexone, and samidorphan. Combining this drug with other substances that cause drowsiness or breathing issues can heighten the risk of severe side effects, such as slow or shallow breathing and extreme drowsiness or dizziness. Inform your doctor or pharmacist if you're using other opioid pain or cough medications like morphine or hydrocodone, alcohol, marijuana (cannabis), sleep or anxiety drugs like Alprazolam, Lorazepam, or Zolpidem, muscle relaxants like Carisoprodol or Cyclobenzaprine, or other antihistamines such as Cetirizine or diphenhydramine.

Check all your medication labels, including those for allergy or cough-and-cold products, since they might contain ingredients that cause drowsiness. Consult your pharmacist on how to use these products safely.

Additionally, some medications can alter how your body processes codeine/promethazine, impacting its effectiveness. Examples of such drugs include azole antifungals like Ketoconazole, bupropion, Fluoxetine, macrolide antibiotics like Erythromycin, paroxetine, quinidine, rifamycins like Rifabutin or Rifampin, Ritonavir, and certain seizure treatments like Carbamazepine or Phenytoin.

This medication might also interfere with specific lab tests, such as some pregnancy tests, blood sugar tests, and amylase or lipase levels, potentially leading to incorrect results. Ensure that all your healthcare providers and laboratory personnel are aware that you're taking this medication.
