Many women take Marvelon without experiencing any side effects.

The following side effects are discussed by women taking Marvelon:
Does Marvelon increase your risk of blood clots? Using a combined hormonal contraceptive such as Marvelon can increase your risk of developing a blood clot compared with not using one. However, the risk is low (between 9-12 out of 10,000 women) and it decreases after your first year of taking Marvelon for the first time. The risk of developing a blood clot also returns to normal within a few weeks of stopping taking Marvelon. You should discuss your personal situation and familial medical history with the GP as part of the prescription process to be sure that taking Marvelon is a suitable risk for you to take.
Does Marvelon make your breasts grow? Marvelon changes the hormones in your body which can in some cases have a temporary impact on the size of your breasts. This change usually settles down once your body has adapted to the medication. Taking Marvelon is not a solution if you want bigger breasts.
Does the Marvelon pill help acne? The combination of hormones in Marvelon has been found in research studies to help acne by reducing the production of sebum, the oily substance which is secreted onto your skin and can cause outbreaks.
Can Marvelon make you depressed or cause mood swings? Changes in mood and low mood are often linked with taking an oral contraceptive pill but research has not been able to either prove or disprove this link.
Can Marvelon cause changes to your weight? Women report changes in weight when being on the contraceptive pill but there is no scientific evidence to prove or disprove this.
Does Marvelon pill stop periods? No, Marvelon is a monophasic 21-day pill which means you take it for 21 days and then have a 7-day break during which you bleed. You can use Marvelon to delay your period by taking the pill back to back without the 7-day break.
Can Marvelon help with painful and heavy periods? Yes, by regulating the hormones in your body Marvelon can help with painful and heavy periods.
Can Marvelon give you low libido? Some women report a lower sex drive when on a combined pill such as Marvelon. The oestrogen in the combined pill regulates the testosterone in your body and can reduce spikes which previously generated periods of having a high sex drive. If you are worried that Marvelon has impacted your sex drive speak to your GP who may suggest you try a contraceptive pill with a different combination of hormones.
