How does generic quetiapine differ from brand-name Seroquel?

Brand-name Seroquel is manufactured by AstraZeneca, while generics are produced by multiple companies.
What are the potential risks of generic quetiapine?
While generics are required to be therapeutically equivalent, some individuals may experience subtle differences due to variations in inactive ingredients. In rare cases, patients might have sensitivities to these inactive components. However, the safety and efficacy of generic quetiapine are overseen by regulatory bodies like the FDA.
