As with any type of hormonal birth control, Tri-Estarylla may have side effects. These could include vomiting, bloating, nausea, bloating, breast tenderness, and fluid retention.
There are also some more severe documented symptoms. These, while unlikely, may include lumps in the breasts, mood changes, unusual changes in vaginal bleeding, blood clots, or severe abdominal pain. Seek immediate medical help if you experience any of the following: sudden dizziness, confusion, swelling/pain/warmth in the calf/groin, sudden shortness of breath, jaw/chest/left arm pain, weakness on one side of the body, vision problems, or unusual headaches. However, it's important to remember that even though these side effects sound scary, they are rare.
Get immediate medical help if you experience symptoms of a serious allergic reaction, such as trouble breathing, itching, swelling, or severe dizziness.
