“Applying ibuprofen to your skin can sometimes cause your skin to become more sensitive than normal to sunlight. Speak to your doctor if this is a problem.”
If you have been taking ibuprofen in tablet form for a long time it can lead to more permanent damage.
“Ibuprofen can cause ulcers in your stomach or gut, especially if you take it by mouth for a long time or in big doses,” the NHS adds.
“If you need to take it for a long time your doctor may also prescribe a medicine to help protect your stomach.”
