When I prescribe a new medication for one of my patients or suggest an over-the-counter (OTC) drug, I like to spend some time with them to explain the medication, how it works, possible side effects, and how to take it. A big part of taking a medication involves knowing what you can or can’t take with it, because combining certain foods with certain medications can have an important effect on how the drug works in your system.

Whether it’s at home, at work, or in the gym, that age-old question of whether to use heat or ice for an injury continues to be debated. And there’s good reason for the debate, as there is no one correct answer to the question – it depends on the injury in question.

Parents often ask about electronic devices and their effects on vision, as many children are spending a significant part of their day on smartphones, tablets, e-readers, laptops, etc. Parents are often concerned that increased screen usage may make their child nearsighted (myopia is the medical term) and result in their child needing glasses.

These parental concerns are particularly important today as a National Eye Institute (NEI) study has found that the prevalence of myopia in the United States increased 66 percent between 1971-1972 and 1999-2004.
