As with any medicine, side effects are possible with nifedipine. Some of the more common side effects include water retention, headaches, constipation, and fatigue. Most people tolerate the medication well, however. If side effects do occur, they are typically minor. If you experience more serious side effects (such as chest pain or signs of an allergic reaction), contact your healthcare provider right away.
