Let's take a minute to talk about your medication.  

This medication contains a combination of both triamterene and hydrochlorothiazide.  

This medication is a diuretic, or 'water pill,' and it treats high blood pressure. This is important because it can reduce your risk of having a heart attack, stroke or kidney problems. In some patients, it is also used to decrease swelling caused by excess fluid.  

At first, some side effects can occur, like mild headaches, dry mouth or upset stomach. It could also make you dizzy, so stand up slowly after you've been sitting or lying down to reduce this. It can also make you urinate more often, and taking your dose earlier in the day can decrease nighttime sleep disruptions. But, if these or other side effects become reasons you want to stop taking this medication, please talk to your doctor or pharmacist.  

In rare cases, serious side effects could occur, so call your doctor right away if you have any unusual changes to your body, including weakness or a slow heartbeat.  

It is important to talk to your doctor or pharmacist first before you take any non-prescription medications. 

For best results, continue taking this medication, and follow your doctor's advice about diet, exercise and checking your own blood pressure.
