Ziprasidone, marketed under the brand name Geodon, is expected to face generic competition in December 2024 [1][2]. This development is significant for patients and healthcare providers as it typically leads to lower medication costs [3].
When does ziprasidone patent exclusivity end?
The patent exclusivity for ziprasidone is set to expire in December 2024. This date marks the point at which other pharmaceutical companies can legally market and sell generic versions of the drug [1][2].
What is the difference between Geodon and generic ziprasidone?
Geodon is the brand-name medication, while generic ziprasidone refers to versions of the drug manufactured by different companies after the brand-name patent expires [3]. Both Geodon and generic ziprasidone contain the same active ingredient and are expected to have the same dosage forms, safety, efficacy, and intended use [3]. The primary difference will be in branding, packaging, and potentially the inactive ingredients used, which do not affect the drug's performance [3].
What are the cost implications of generic ziprasidone availability?
The introduction of generic ziprasidone is anticipated to significantly reduce the cost of treatment for ziprasidone [3]. Brand-name drugs are generally more expensive than their generic counterparts. Once generics enter the market, competition drives down prices, making the medication more accessible and affordable for patients [3].
Who makes generic ziprasidone?
Following the patent expiry in December 2024, various pharmaceutical manufacturers will be able to produce and distribute generic ziprasidone. Companies specializing in generic drug production, such as Teva Pharmaceuticals, Mylan (now part of Viatris), and others, are likely to be among those offering generic versions [4]. The specific manufacturers will become clearer as the expiration date approaches and regulatory approvals are granted.
What is ziprasidone used for?

What are the side effects of ziprasidone?
Common side effects of ziprasidone can include drowsiness, dizziness, nausea, constipation, and headache [1][5]. More serious side effects may involve irregular heart rhythms, a condition known as QT prolongation, and metabolic changes like weight gain or increased blood sugar [1][5]. Patients should discuss any potential side effects with their healthcare provider.
