Tadalafil, the active ingredient in Cialis, has seen the introduction of generic versions in the United States [1].
When did generic tadalafil become available?
The U.S. market saw the launch of generic tadalafil around November 2017 [2]. This followed the expiration of key patents held by Eli Lilly and Company, the original manufacturer of Cialis [3].
How much does generic tadalafil cost?
Prices for generic tadalafil can vary significantly depending on the dosage, quantity, and pharmacy. However, generic medications are typically much less expensive than their brand-name counterparts. For instance, a 30-day supply of a lower dose of generic tadalafil might cost around $20 to $30, whereas the same quantity of brand-name Cialis could cost several hundred dollars [4]. These savings are a primary driver for patients seeking generic options.
What are the different dosages of generic tadalafil?
Generic tadalafil is available in the same dosage strengths as brand-name Cialis, typically including 2.5 mg, 5 mg, 10 mg, and 20 mg tablets [1]. These dosages are prescribed for various conditions, including erectile dysfunction, benign prostatic hyperplasia, and pulmonary arterial hypertension [5].
Are there any differences between generic and brand-name tadalafil?
Generic tadalafil is bioequivalent to brand-name Cialis, meaning it contains the same active ingredient and works in the body in the same way [6]. Regulatory bodies like the U.S. Food and Drug Administration (FDA) require generic drugs to meet stringent standards for safety, efficacy, and quality [7]. The primary differences are in inactive ingredients, such as fillers and dyes, and the brand name itself [6].

What conditions is tadalafil used to treat?
Tadalafil is primarily prescribed to treat erectile dysfunction (ED) [1]. It is also used to manage the symptoms of benign prostatic hyperplasia (BPH), often referred to as an enlarged prostate [1]. Additionally, tadalafil is approved for treating pulmonary arterial hypertension (PAH) under the brand name Adcirca, though generic versions of Adcirca may have different market dynamics [5].
Who manufactures generic tadalafil?
Multiple pharmaceutical companies manufacture generic tadalafil. Following patent expirations, many generic drug manufacturers received approval from the FDA to produce and market their versions of the drug [2]. These include companies like Teva Pharmaceuticals, Mylan, and others [8].
