Crestor can interact with other drugs prescribed to lower cholesterol. Your doctor may prescribe Crestor with one of these drugs if your cholesterol or triglyceride levels aren’t improved enough with Crestor alone.

Examples of other cholesterol drugs include:

What could happen

Taking Crestor with other cholesterol drugs can raise your risk of muscle-related side effects, such as muscle pain or weakness. It can also increase your risk of a rare side effect called rhabdomyolysis (breakdown of muscle tissue). Rhabdomyolysis can lead to kidney problems that may be fatal in rare cases.

What you can do

If your doctor prescribes Crestor with another cholesterol drug, they may prescribe a Crestor dosage that’s lower than usual. You should not take a higher dose of either medication than your doctor prescribes.

If you take Crestor with another cholesterol drug, talk with your doctor right away if you have any symptoms of muscle problems. These may include muscle pain, tenderness, or weakness, especially if you also have a fever or feel unusually tired.

If you have muscle problems while taking Crestor with another cholesterol drug, your doctor will likely recommend that you stop taking both drugs.

Interaction with antacids

Crestor may interact with antacids, which are medications commonly used to relieve indigestion (upset stomach) or heartburn. They may be prescribed by your doctor, but you can also buy them over the counter.

Examples of antacid medications:

  • aluminum hydroxide/magnesium hydroxide (Mylanta, Maalox, others)
  • calcium carbonate (Tums, others)
  • calcium carbonate/magnesium hydroxide (Rolaids, others)

What could happen

Taking an antacid at the same time of day as Crestor can prevent your body from absorbing Crestor properly. This could make Crestor less effective.

What you can do

You should not take an antacid within 2 hours of taking a dose of Crestor. If you need an indigestion remedy in the 2 hours before or after taking Crestor, talk with your doctor or pharmacist. They can recommend a medication that doesn’t interact with Crestor.

Interaction with warfarin

Crestor can interact with warfarin (Jantoven), a blood thinner doctors prescribe to treat or help prevent blood clots.

What could happen

Taking Crestor with warfarin could increase the blood-thinning effect of warfarin. This could raise your risk of bleeding.

What you can do

If your doctor prescribes Crestor with warfarin, they’ll usually order frequent blood tests to check your international normalized ratio (INR). INR is a measure of your blood clotting time.

Your doctor will likely check your INR before you start taking Crestor with warfarin. They’ll also likely check your INR after any changes to your dose of Crestor or warfarin.

Talk with your doctor right away if you notice any unusual bruising or bleeding while taking Crestor with warfarin. Your doctor may need to adjust your warfarin dosage.
