How does lipitor interact with vitamin d?

How does vitamin D affect Lipitor levels in the body?

Lipitor (atorvastatin) and vitamin D are often taken together. No direct pharmacokinetic interaction exists between them. Studies show vitamin D may improve statin tolerance in patients who experience muscle symptoms. One study found patients with vitamin D deficiency had higher rates of myalgia when taking statins, and correcting the deficiency reduced those complaints.

What happens if vitamin D levels stay low while taking Lipitor?

Low vitamin D may worsen muscle pain or weakness that manchen patients report on statins. Patients with 25-hydroxyvitamin D levels below 20 ng/mL showed higher rates of muscle-related side effects. Correcting the deficiency before or during statin therapy can lower those complaints.

How long does the benefits of correcting vitamin D deficiency take?

Effects from raising vitamin D levels appear within weeks. Patients whose low vitamin D was corrected showed improvements in muscle symptoms in 4-8 weeks. Some studies reported a reduction in statin discontinuation rates after vitamin D repletion.

Can vitamin D supplements cause side effects when used with Lipitor?

Vitamin D supplements at normal doses do not increase Lipitor side effects. Normal range doses (1,000-2,000 IU daily) are safe to take together. Excess vitamin D can lead to hypercalcemia, but that does not specifically interact with Lipitor.

What alternatives exist if vitamin D supplementation does not fixes muscle pain?

Alternatives for statin-associated muscle symptoms include switching to a different statin, reducing Lipitor dose, or taking it every other day. Some patients tolerate a lower-dose rosuvastatin or pitavastatin. Taking Lipitor at bedtime or switching to a non-statins such as ezetimibe or PCSK9 inhibitors works for manchen patients.

Who manufactures Lipitor?

Pfizer manufactures Lipitor.
