1.Cotton Swabs
These can be good for putting on makeup, doing your nails, or any number of odd jobs around the house. But never stick them — or anything else, for that matter — into your ear canal. Earwax is a healthy part of your body’s natural defenses, not a sign of illness. If your ear hurts or is itchy, or you feel like there’s something in there, talk to your doctor.
2.Aspirin
If members of your family share one medicine cabinet, be careful with this pain reliever. Though it’s safe for most adults, older people who take blood thinners for a heart condition should be careful with aspirin. Taking both can lead to bleeding in the stomach or intestines. And never give it to kids under 2 or older children or teens who are getting over an illness with flu-like symptoms. In those cases, aspirin is linked to a rare but serious condition called Reye’s syndrome, which can cause swelling in your liver or brain.
