What side effects does Nextstellis (nexplanon?) have?
Nextstellis is a prescription hormonal contraceptive (a combined pill) that can cause side effects similar to other birth control pills. Commonly reported effects include changes in bleeding patterns (such as spotting between periods or changes in the timing/amount of bleeding), nausea, headache, breast tenderness, and mood changes.
Serious but less common risks associated with combined hormonal contraceptives can also occur, including blood clots and other cardiovascular complications.
What are the most common Nextstellis side effects?
People taking combined hormonal contraceptives often report mild, short-term side effects—especially during the first few months. These can include:
- Spotting or breakthrough bleeding
- Nausea
- Headache
- Breast tenderness
- Cramps or bloating
- Mood changes
If bleeding is unusually heavy, persistent, or worsening, clinicians typically advise evaluation.
What serious side effects should you watch for?
Combined oral contraceptives carry warnings about potentially dangerous events. Seek urgent care if you have signs of:
- A blood clot in the leg (pain, swelling, warmth in one leg)
- A blood clot in the lung (sudden shortness of breath, chest pain, coughing blood)
- Stroke (sudden weakness/numbness on one side, trouble speaking, facial droop)
- Heart attack (chest pressure/pain, pain radiating to arm/jaw)
Also get urgent medical help for severe symptoms such as sudden severe headache, vision changes, or jaundice (yellowing of skin/eyes).
Does Nextstellis cause weight gain or acne?
Weight change and skin changes can happen with hormonal contraceptives, but experiences vary widely. Some people notice increased or decreased appetite/weight, while others see improvement in acne due to hormonal effects. If weight gain or acne worsens significantly after starting, a clinician may adjust the regimen.
How long do side effects last after starting Nextstellis?
For many people, early side effects (like nausea, breast tenderness, or irregular bleeding/spotting) improve after the first couple of cycles as the body adjusts. Persistent or worsening symptoms after a few months are a common reason to reassess the prescription with a healthcare provider.
Who should not take Nextstellis (and may have higher risk from side effects)?
Risk of serious complications is higher for some people using combined hormonal contraceptives, especially if they have risk factors such as smoking, a history of blood clots, certain clotting disorders, uncontrolled high blood pressure, or specific migraine patterns. A clinician can screen for these risks before prescribing.
When should you call a doctor about Nextstellis side effects?
Contact a healthcare professional promptly if you have:
- Bleeding that is very heavy or doesn’t settle after the first few months
- Symptoms of possible blood clots (pain/swelling in one leg, sudden breathlessness, chest pain)
- Severe headaches, vision changes, or jaundice
- Severe mood changes or depression symptoms
