Medicine tips

• Read the fact sheet that comes with your medicine. It tells you when and how to take it. Ask for a medicine sheet if you don’t get one.

• If you take 2 or more doses each day, take the last dose before dinner if you can. That way you’ll get up fewer times during the night to go to the bathroom. However, make sure you have enough time between doses during the day. 

• If you miss a dose, take it as soon as you remember. If it's almost time for the next dose, skip the missed dose. Don't take a double dose.

• If you miss 2 or more consecutive doses, call your health care provider. You may be at risk for fluid buildup.

For your safety

• Follow your health care provider’s guidelines for potassium intake. You may need to take a potassium supplement. Or you may need to stay away from potassium supplements, salt substitutes with potassium, or large amounts of high-potassium foods (such as bananas, potatoes, broccoli, and milk). Recommendations for potassium will depend on the type of diuretic you are prescribed along with your kidney function and other factors. Your provider will likely want to check your potassium level regularly while you are taking this medicine.

• Talk to your provider about whether it's safe for you to drink alcohol while taking this medicine.

• Get up slowly when you are sitting or lying down. This helps prevent dizziness and falls due to dizziness.

• Ask your provider or pharmacist before you take any other prescription or nonprescription medicine or herbal supplements. Some of them may interact with your diuretic and keep it from working correctly.

• Limit exposure to sunlight. A diuretic may increase your sensitivity to the sun. Even brief sun exposure may cause skin rash, itching, redness, or other discoloration. It may also lead to severe sunburn. To protect your skin do the following:

  • Stay out of direct sunlight, especially between 10 a.m. and 2 p.m., whenever possible. The amount of direct sunlight exposure you have can vary depending on where you live.

  • Apply a daily sunblock of at least SPF 15 (or higher) to any exposed skin, including your lips.

  • Wear protective clothing, such as a hat and sunglasses, when you are outdoors.

  • Don't use sunlamps and tanning booths.

  • Long-sleeve shirts and pants in the summer can help protect your skin.
