- Signs of a stroke, such as vision or speech changes, weakness or numbness in an arm or leg, and a severe headache
- Chest pain or heaviness, which may be signs of a heart attack
- Sudden loss of vision or vision changes, which can be a sign of a blood clot in the eye
- Signs of liver damage, such as yellowing of the whites of the eyes or skin (jaundice), dark urine, and upper right abdominal pain (stomach pain)

It is possible that you may experience some or none of the CombiPatch side effects listed in this article. Unfortunately, it can be difficult to tell whether any particular side effect is caused by CombiPatch or by other factors. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking CombiPatch or if something "just does not seem right." While it may not be a side effect of the medication, your healthcare provider will be able to diagnose and treat the problem.
