Let's take a minute to talk about your medication. This is Cimduo. When used with other medicines, it helps treat HIV-1 infection and keeps it under control. Cimduo contains two medicines in each tablet. Cimduo is often taken once a day, at the same time each day. You should take it exactly how your doctor tells you to. You can take your dose with or without food. It is important to not miss any doses. If you do, the virus could get worse and become harder to treat. Most people tolerate this medicine well. Common side effects include pain, diarrhea and headache. These are normal if they are mild and should go away. Depression or a rash is also common. These are usually mild but could be a symptom of a more serious problem. Tell your doctor right away if you notice any unusual changes to your body or mood. If these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist. As with any medicine, rare but more serious side effects can occur. With Cimduo, these include liver and kidney problems and an increase in lactic acid. You should read the 'Patient Information Guide' to know which symptoms to watch for and when to report changes. Cimduo can also cause a flare up of hepatitis B if you already have it. To prevent this, you must not miss doses or stop taking it, unless your doctor says it is okay. Cimduo can interact with other medicines. You should always check with your doctor or pharmacist before taking any other medicines. Women must talk to their doctors before becoming pregnant and should not breastfeed. For best results with Cimduo, be sure to plan ahead for refills. Also, store it in the original bottle with the lid tightly sealed.
