Mercilon is very well-tolerated and most women do not experience side effects. In those that do, nausea, headaches and breast tenderness are the most common and usually settle quickly. Spotting between periods is also common and should settle within the first 3 cycles.
Occasionally skin changes such as acne, decreased libido (sex drive), altered mood and fatigue are reported.
If you develop any of these symptoms and they are persisting, or you are concerned, please speak with your doctor. There are many alternative pill options to consider.
Combined pills like Mercilon can cause increases in blood pressure. It is not medically safe to take this pill if you have high blood pressure. A blood pressure check should be performed every 6 months to monitor for this as you are unlikely to have any symptoms.
For full details of the potential side effects of these medications, please ensure that you read the patient information leaflet that comes with your medication before you start to use it.
