What side effects may mixing lipitor antacids cause?

What happens if you mix Lipitor and antacids?

Mixing Lipitor (atorvastatin) with certain antacids can increase the risk of myopathy, a muscle disorder. This is because some antacids can reduce the absorption of Lipitor, making it work less effectively. Some antacids that may interact with Lipitor include:

* Magnesium-based antacids (e.g., Maalox, Mylanta)
* Aluminum-based antacids (e.g., Tums, Rolaids)
* Calcium carbonate-based antacids (e.g., Tums, Rolaids)

However, not all antacids interact with Lipitor. For example:

* Ranitidine (Zantac) is a histamine-2 (H2) blocker that can be taken with Lipitor without increasing the risk of myopathy.[1]
* Antacids containing aluminum hydroxide and magnesium hydroxide, such as Aluminum Hydroxide and Magnesium Hydroxide (Maalox), should be taken 1-2 hours after taking Lipitor to minimize the risk of interaction.[2]

Common side effects with Lipitor and antacids

Even if you don't take Lipitor and antacids together, some side effects may still occur. Common side effects of Lipitor include:

* Muscle pain or weakness
* Muscle tenderness or cramping
* Nausea
* Diarrhea
* Abdominal pain

In rare cases, Lipitor can cause more serious side effects, such as rhabdomyolysis (rapid breakdown of muscle tissue), kidney damage, or liver damage.

What should you do if you take Lipitor and antacids together?

If you're taking Lipitor and antacids, talk to your doctor or pharmacist about potential interactions. They can help you choose an antacid that won't increase the risk of myopathy or other side effects. If you experience any unusual or severe side effects while taking these medications, seek medical attention immediately.
