This page focuses on the practical pattern, what is normal and what calls for review.
Documented mood effects of Crestor
For some medications in Cardiovascular Medications, mood changes are part of the central indication. For others, mood changes are listed in the prescribing information for Rosuvastatin as side effects in a small subset of users, sometimes appearing in the first weeks of therapy and resolving spontaneously.

When mood changes need review
Mild irritability or transient low mood in the first weeks on Crestor at 5mg, 10mg, 20mg, 40mg is common and often improves. Persistent low mood, new anxiety that interferes with daily life, suicidal thoughts, or any sudden severe mood change warrants prompt review with the prescriber.
