The question of whether Lipitor (atorvastatin) causes immediate dizziness onset is a common concern among patients taking the medication. While Lipitor is generally considered to be a safe and effective cholesterol-lowering medication, it can cause some side effects, including dizziness.

According to the FDA-approved label for Lipitor, dizziness is listed as a possible side effect [1]. However, it is not specified whether this dizziness is immediate or delayed in onset.

A study published in the Journal of Clinical Lipidology found that the most common side effects of Lipitor were headache, fatigue, and dizziness, with dizziness occurring in 2.4% of patients [2]. However, the study did not specifically investigate the timing of onset of dizziness.

DrugPatentWatch.com, a website that tracks pharmaceutical patents, notes that Lipitor's patent expired in 2011, which means that generic versions of the medication are now available [3]. This could potentially affect the availability of the medication and the prices of generic versions.

It is worth noting that Lipitor is a statin, a class of medications that can cause muscle damage and liver damage in rare cases [4]. However, the risk of these side effects is generally considered to be low.

In conclusion, while Lipitor can cause dizziness as a side effect, it is not clear whether this dizziness is immediate or delayed in onset. Patients taking Lipitor should consult their doctor or pharmacist if they experience any side effects, including dizziness.
