Hello, Cerazette is a progestin-only contraceptive pill, also known as the mini-pill. While it is an effective form of contraception, it can cause side effects in some women. Mood swings and changes in sexual appetite are common side effects of progestin-only pills like Cerazette. Other reported side effects include irregular bleeding or spotting, headaches, weight gain, breast tenderness, and acne. If you are experiencing bothersome side effects, it is important to speak with your healthcare provider before stopping the medication. They may suggest alternative forms of contraception or help you manage any side effects you are experiencing. Abruptly stopping the medication can also cause withdrawal symptoms or affect your menstrual cycle. Your healthcare provider may also want to evaluate your symptoms to ensure they are not indicative of an underlying medical condition. While mood swings and changes in sexual appetite can be common side effects of hormonal contraceptives, it is important to rule out any other underlying conditions that may be contributing to these symptoms. In summary, if you are experiencing bothersome side effects while taking Cerazette, it is important to speak with your healthcare provider before stopping the medication. They can help you manage any side effects and suggest alternative forms of contraception. Take care. Hope I have answered your question. Let me know if I can assist you further.
