Potential Drug Interactions: Codeine and Propranolol
This report highlights the possible interactions between codeine and propranolol. When taken together, these drugs may have additive effects in lowering blood pressure. This can cause symptoms such as headache, dizziness, lightheadedness, fainting, and changes in pulse or heart rate. These side effects are more likely to occur at the beginning of treatment, after a dose increase, or when treatment is restarted after an interruption. If you experience any of these symptoms and they persist or become bothersome, inform your doctor immediately. It is important to inform your doctor about all medications you are taking, including vitamins and herbs. Do not stop taking any medication without consulting your doctor first. Additionally, avoid driving or operating heavy machinery until you know how these medications affect you, and be cautious when getting up from a sitting or lying position.
Drug and Food Interactions
Food can increase the levels of propranolol in your body. Therefore, it is recommended to take propranolol at the same time each day, preferably with or immediately following meals. This will make it easier for your body to absorb the medication. Avoid consuming alcohol while taking propranolol, as it can increase drowsiness and dizziness. Propranolol is only one part of a comprehensive treatment program that also includes diet, exercise, and weight control. It is important to follow your diet, medication, and exercise routines closely.
