How long after taking lipitor should i wait to get my liver function test?

Why are liver function tests recommended after Lipitor?"

Liver function tests are necessary when starting a new medication, such as Lipitor (atorvastatin), to ensure the drug is not causing any abnormal liver function [1]. Lipitor belongs to a class of drugs known as statins, which can sometimes increase liver enzymes in people with pre-existing liver conditions or those who consume excessive amounts of alcohol.

**Lipitor's potential liver impact and liver function testing

Although rare, taking Lipitor can sometimes cause severe liver damage, known as rhabdomyolysis [2]. However, in most cases, liver function tests are elevated and then return to normal without the need for medication discontinuation. As per the FDA, patients taking Lipitor should have their liver function monitored at the beginning of treatment (before starting medication) and then 12 weeks later [3]. If your doctor orders liver function testing at a different interval, be sure to follow their recommendations.

When to expect results and what to do if you have abnormal test results

It's essential to follow your doctor's advice on when to expect results. Typically, liver function test results can be ready within 1-3 days of getting your blood drawn. If your results show abnormal liver function, your doctor may choose to adjust your Lipitor dosage, switch you to a different statin, or discontinue the medication altogether.

Monitoring and follow-up

To minimize risks and monitor any potential liver function changes, your doctor may schedule follow-up visits with liver function tests after initiating Lipitor. Follow your physician's guidance for post-treatment monitoring.
