When you take prescription medicines, of course we all have to be in the sun, you need to understand there are certain medications that can make your skin much more sun sensitive. Any of the sulfonamide drugs can do that. So, if you take a sulfa antibiotic drug, if you take a diuretics – almost all diuretics except two are sulfa based. Cholesterol pills, all of the over the counter pills such as non-steroidal anti-inflammatory drugs such as ibuprofen, Aleve – those type of drugs tend for you to be more sun sensitive. You need to be aware of that and if you are taking those, you need to consider using a sunscreen that has a high SPF number. I would recommend at least a SPF of 70 or higher. It has to do with the wave length of light that is attracted by the medication and it takes high numbers of sunscreens to block that light.
