Over 102 million people in America have high cholesterol. High cholesterol can lead to a number of different health issues, including:

  • Heart disease
  • Stroke
  • Chest pain
  • Heart attack

You can lower your cholesterol via proper nutrition, quitting smoking and losing weight. You can supplement these things with various medications to help lower cholesterol levels.

One such medication is Crestor. While Crestor is effective at lowering bad cholesterol, there are certain side effects you should be aware of.

Keep reading to learn Crestor side effects before you start this medication.

What Is Crestor?

As we mentioned, Crestor is a medication used to lower bad cholesterol while simultaneously increasing good cholesterol.

Lowering bad cholesterol and raising good cholesterol levels will help decrease your risk of heart attack, stroke, and cardiovascular disease.

It’s taken via an oral tablet usually once per day.

Common Crestor Side Effects

There are certain mild side effects that are common when taking Crestor. These more common side effects of Crestor include:

  • Nausea
  • Headache
  • Weakness
  • Abdominal pain
  • Confusion
  • Memory Loss

These side effects are usually mild and will go away. However, if they become severe or you find that they’re affecting your everyday life, you should speak to your doctor.

Serious Crestor Side Effects

Besides the more common side effects, there are some serious side effects that can have a huge impact on your overall health.


One of these more serious side effects of Crestor is muscle pain and weakness. If you notice any unexplained muscle weakness, pain, or tenderness, you should speak to your doctor as soon as possible. This could be a sign that the Crestor is causing myopathy, which can eventually lead to kidney damage and even death.

Diabetes Risk

In rare cases, Crestor use can increase your blood sugar levels. This can cause problems for people with diabetes, and it’s been hypothesized that this can even lead to the development of type 2 diabetes.

Liver Problems

Crestor works by interacting with your liver to decrease bad cholesterol. This also means, however, that Crestor has the potential to cause serious liver problems.

Symptoms to watch out for include:

  • Unusual weakness/tiredness
  • Loss of appetite
  • Dark urine
  • Jaundiced skin/eyes (yellow skin and yellowed whites of the eyes)
  • Upper abdominal pain

If you notice any of these symptoms while taking Crestor, you need to speak with your doctor as soon as possible, as they could be a sign of serious liver problems.

When You’re At Higher Risk for Serious Side Effects

Certain things put you at a higher risk for muscle and liver problems. These include:

  • Being over the age of 65
  • Thyroid problems
  • Previous liver issues
  • Alcohol abuse
  • Being on a high dose of Crestor
  • Kidney problems

If any of these risk factors describe you, speak with your doctor about your risk of developing side effects.
