You may experience some mild side effects after an etonogestrel implantation. Talk to your doctor if these reactions become severe, or do not go away within a few days.
Common side effects reported after receiving an etonogestrel implant include:
- Changes in menstrual patterns
- Change in mood
- Breast tenderness
- Weight changes
This is not a complete list of adverse reactions. Seek medical attention right away if you experience breathing problems, changes in blood pressure, irritation at the injection site, fever symptoms, dark brown urine, infection at the injection sites, or other more severe symptoms after etonogestrel is implanted into your arm.
As with all prescription medication, be sure to inform the prescribing doctor about any medical conditions you have been previously diagnosed with and any medication/ supplements you are currently taking before receiving an etonogestrel implantation. Etonogestrel can interact with other forms of medication, causing potentially serious side effects. In addition, let your doctor know if you are pregnant or plan on becoming pregnant before starting treatment with this medication.
