Monitoring your blood pressure is important, as this medication might cause an increase. Alert your healthcare provider if you observe elevated readings. More serious side effects, while uncommon, should be addressed immediately. These include lumps in the breast, significant mood changes, severe abdominal pain, or unusual vaginal bleeding patterns. Symptoms such as dark urine or yellowing of the skin and eyes also require prompt medical attention.

Rare, but potentially life-threatening, are incidents of blood clots, which can lead to heart attacks, strokes, or clots in the lungs or legs. Seek urgent care if you experience chest pain, confusion, sudden dizziness, swelling or warmth in the calf, difficulty speaking, or sudden severe headaches. Additionally, any sudden vision changes, shortness of breath, or weakness on one side of the body are critical symptoms.

Allergic reactions to this medication are very rare but require immediate medical help if they occur. Symptoms to watch for include rash, itching, swelling (especially of the face, tongue, or throat), severe dizziness, or trouble breathing. Always stay vigilant for any other unusual effects and consult your healthcare provider if they arise.

Inform your doctor when you start any new medication and discuss whether you need additional birth control methods. Additionally, notify your doctor if you experience new spotting or breakthrough bleeding, as these may indicate that your birth control is not functioning properly.
