Some people who take cinoxacin may become more sensitive to sunlight than they are normally. Exposure to sunlight, even for brief periods of time, may cause severe sunburn; skin rash, redness, itching, or discoloration; or vision changes. When you begin taking this medicine:
Stay out of direct sunlight, especially between the hours of 10:00 a.m. and 3:00 p.m., if possible.
Wear protective clothing, including a hat and sunglasses.
Apply a sun block product that has a skin protection factor (SPF) of at least 15. Some patients may require a product with a higher SPF number, especially if they have a fair complexion. If you have any questions about this, check with your health care professional.
Do not use a sunlamp or tanning bed or booth.
If you have a severe reaction from the sun, check with your doctor.
