She was prescribed Montelukast, cetirizine, famotidine and advised that she could continue diphenhydramine as needed. She was given a prescription for a steroid, however was told not to fill it until two weeks was up after the vaccine. She had no relief by the next morning and visited her primary care physician. Later, she called CVS and was told to use cold compresses and not to take any over the counter medication. At that point, she felt that if she could have ripped all of her skin off, she would have.
