The generic version of Celexa, citalopram hydrobromide, became available in the United States in 2010 [1]. This followed the expiration of its primary patents [2].
When did Celexa patents expire?
Celexa (citalopram) faced patent expirations that allowed for generic competition. The main U.S. patent for Celexa expired around 2007-2008, leading to the introduction of generic citalopram by multiple manufacturers in 2010 [1][2]. Further exclusivity periods may have existed for specific formulations or indications, but the core patent expiry enabled widespread generic availability [3].
How much does generic Celexa cost?
The cost of generic citalopram can vary significantly depending on the pharmacy, insurance coverage, and dosage [4]. However, generic medications are generally substantially less expensive than their brand-name counterparts. For example, a 30-day supply of brand-name Celexa could cost upwards of $150-$200 without insurance, while generic citalopram might range from $10-$40 or less, depending on the factors mentioned [4][5]. Patients can compare prices across different pharmacies or consult their insurance provider for the most accurate cost information.
What is citalopram hydrobromide?
Citalopram hydrobromide is the active pharmaceutical ingredient in both brand-name Celexa and its generic versions [6]. It is an antidepressant belonging to a class of drugs called selective serotonin reuptake inhibitors (SSRIs) [7]. Citalopram works by increasing the levels of serotonin, a neurotransmitter that helps regulate mood, in the brain [7].
Who makes generic Celexa?
Multiple pharmaceutical companies manufacture generic citalopram. Some of the manufacturers that have produced or currently produce generic citalopram include Teva Pharmaceuticals, Mylan Pharmaceuticals, and Apotex Inc., among others [8][9]. The availability of generic versions from different producers contributes to market competition and helps keep prices down.
What are the side effects of citalopram?
Common side effects of citalopram can include nausea, dry mouth, insomnia, drowsiness, diarrhea, increased sweating, and sexual dysfunction [7]. Less common but serious side effects can involve changes in heart rhythm, suicidal thoughts, serotonin syndrome, or withdrawal symptoms if the medication is stopped abruptly [7]. Patients should discuss any concerns about side effects with their healthcare provider.
Can I switch from Celexa to generic citalopram?
Switching from brand-name Celexa to a generic citalopram formulation is generally considered safe and effective, as the generic version is bioequivalent to the brand-name drug [10]. Bioequivalence means that the generic drug is absorbed into the bloodstream and has the same therapeutic effect as the brand-name drug. Patients should consult their doctor or pharmacist before making any changes to their medication regimen to ensure a smooth transition [10].
