Does lipitor increase daytime drowsiness in many users?

Does Lipitor cause daytime drowsiness?

Lipitor (atorvastatin) is a statin used to lower cholesterol. Clinical data does not show a strong link between Lipitor and daytime drowsiness in large patient populations.

How common is drowsiness as a side effect?

Drowsiness appears in post-marketing reports but remains uncommon. The prescribing information lists fatigue and asthenia as infrequent complaints, but these occur at rates similar to placebo in controlled trials.

What do clinical studies show?

In pooled analysis of clinical trials, fatigue occurred in 4% of Lipitor-treated patients versus 4% in placebo-treated patients. Fatigue and asthenia do not correlate with daytime drowsiness specifically.

Does Lipitor affect sleep architecture?

Research on statins and sleep shows mixed results. Some studies report improved sleep quality after cholesterol reduction, some reports show increased muscle pain that can disrupt sleep indirectly, indirectly causing daytime tiredness.
