Promethazine gel can cause several side effects, some mild and others more serious. Always inform your doctor about any unusual symptoms you experience.
- Common side effects: These often resolve on their own and may include drowsiness, dizziness, dry mouth, blurred vision, and constipation. Less common side effects: These are less frequent but still possible, including nausea, vomiting, restlessness, and anxiety. If these persist or worsen, consult your physician immediately.
Serious side effects, though rare, require immediate medical attention. These include:
- Allergic reactions: Symptoms such as rash, hives, swelling of the face, lips, tongue, or throat, difficulty breathing or swallowing indicate a serious allergic reaction. Seek emergency medical help immediately. Neuroleptic malignant syndrome (NMS): This rare but life-threatening condition involves high fever, muscle stiffness, altered mental state, and irregular heartbeat. Emergency medical care is vital if these symptoms appear. Blood disorders: While uncommon, promethazine can sometimes affect blood cells. Unexplained bruising, bleeding, or pale skin necessitate a prompt doctor’s visit.
