Time to Read: About 1 minute

This resource will help you hydrate yourself after getting high-dose cisplatin chemotherapy (chemo).

Cisplatin can affect your kidneys. To keep your kidneys from getting damaged, you’ll need to drink plenty of liquids after getting cisplatin chemotherapy. Drinking enough liquids is especially important for the first 2 days after your chemotherapy.

How much to drink

The day of your chemotherapy

Starting right after your get your chemotherapy treatment, drink at least 4 (8-ounce) glasses of liquids before the next day.

The day after your chemotherapy

Drink 8 to 12 (8-ounce) glasses of liquids every day for 1 week after your treatment.

Take your anti-nausea medicine as instructed by your doctor.

  
Remember, it’s very important to drink enough liquids for the first 2 days after getting cisplatin chemotherapy.

What to drink

  • Drink any type of caffeine-free liquids, such as:
    • Water
    • Milk
    • Juices
    • Gatorade®
    • Propel®
    • Soft drinks (soda) without caffeine, such as lemon-lime soda, ginger ale, or caffeine-free cola.
  • Avoid drinks with caffeine or alcohol. You may have 1 cup (8 ounces) of caffeinated coffee or tea per day.
  • Add water to sweet drinks, such as juice (for example, half water and half juice). This will lower the amount of sugar you drink. Having too much sugar can cause diarrhea (loose or watery bowel movements).
  • If you have diabetes or high blood sugar, choose drinks with no sugar.

Keep track of what you drink

On the day of your chemotherapy appointment, write down the date and time you had something to drink. Also write down the number of ounces that you drank. Follow the same steps for the day after your chemotherapy appointment. This will help you make sure you’re reaching your goal.

 
Call your doctor or nurse if you:

 

  • Have any signs of kidney problems, such as:
    • Being unable to urinate (pee).
    • Urinating less than you normally do.
    • Blood in your urine.
    • Sudden weight gain.
  • Have any signs that you’re retaining (holding onto) fluids, such as swelling in your legs or feet, or shortness of breath.
  • Have nausea (feel like you are going to throw up), vomiting (throwing up), or diarrhea (loose, watery stools).
  • Feel dizzy.
  • Are unable to eat or drink for more than 24 hours after getting high-dose cisplatin.
  • Have a fever of 100.4° F (38° C) or higher.
