  • There are a number of medicines that Atacand can interact with (see Atacand Drug Interactions).
  • Atacand may cause extreme low blood pressure in some people. Extreme low blood pressure is more likely to happen in people who are taking a diuretic, who are on dialysis, who have diarrhea or vomiting, who have excessive sweating, or who have congestive heart failure. This is why it is important to drink fluids regularly while taking Atacand. If you have any possible symptoms of low blood pressure, such as dizziness, light-headedness, or fainting, contact your healthcare provider. If you have fainted, stop taking Atacand until you have talked to your healthcare provider.

Also, make sure not to drive, operate any heavy machinery, or perform any other tasks that require alertness before you know how Atacand affects you.

If you become pregnant while taking Atacand, contact your healthcare provider immediately (see Atacand and Pregnancy for more information).
  • While taking Atacand, do not use potassium supplements or salt substitutes with potassium unless you have discussed this with your doctor. This is because in some people taking Atacand, potassium in the blood can increase to dangerous levels.
  • This medication may cause a decrease in kidney function, especially in people who are elderly, have kidney disease, have severe congestive heart failure (CHF), or are taking nonsteroidal anti-inflammatory drugs (NSAIDs) or diuretics (water pills).

Contact your healthcare provider if you notice a decrease in urination or swelling in your hands, legs, ankles, or feet, which can be signs of kidney problems.


  • If you have moderate to severe liver disease, such as cirrhosis, your body may metabolize the Atacand differently than intended. Therefore, your healthcare provider will monitor your situation more closely.
  • If you are nursing, it is not known whether or not Atacand passes through your breast milk. Therefore, if you are nursing, talk with your healthcare provider about whether you should stop taking Atacand or stop breastfeeding.
