Having diabetes means you're at greater risk for other conditions. These include high blood pressure, heart disease, kidney problems, and depression. Along with your diabetes medicine, you may take other medicines to keep these conditions under control. If you have health conditions not related to diabetes, such as arthritis or asthma, you may also need to use medicines to treat them. You could end up taking many types of medicine every day. The more medicines you take, the greater the risk for a medicine mistake.
A medicine interaction happens when 2 or more medicines react with each other to cause an unexpected or harmful effect. Taking several medicines increases the risks of a harmful interaction. And when you're trying to keep track of several pills, it's all too easy to make a mistake. You might forget a dose or confuse one pill for another. Or you could take pills at the wrong time.
