Just like any other healthcare medication, these pills come with their fair share of cons or side effects. Some of the common side effects that almost many of them experience includes mild headaches, dizziness, nausea, nose blockage, hot flushes, and blurred or tinted vision. However, many a time, people might get severe symptoms like chest pain, a seizure, an allergic reaction, and sudden loss or decrease of visions. Seek immediate medical attention if you experience any of these severe side effects.
