These days, some of us have so many medications to worry about that it can be hard to keep track. Many of us have multiple doctors too. Picture this. Your psychiatrist prescribes Zyrtec. Your cardiologist prescribes medicine for your heart condition. Your general doctor prescribes medication for your migraines. Each of these doctors give you something different. The scary thing is, not all of them may realize it if some of you medications interact badly with each other. That is why Epocrates online is so great. It can really help you keep track of dosages and side effects. So that something bad doesn't happen.
