The most common side effects of Cipro include nausea, diarrhea, vomiting, headaches, restlessness, and skin rash. Taking Cipro with food may help to reduce some stomach-related side effects such as nausea. Cipro can make the skin more sensitive to sunlight, or "photosensitive." Symptoms of a photosensitivity reaction include redness, warmth, blisters, swelling, and sometimes rash. Protecting yourself with a broad-spectrum sunscreen with an SPF of at least 15 is recommended.
