Tadalafil Product Information
Tadalafil is the generic, unbranded version of Cialis and contains the same active ingredient. Like Cialis, it is known for its long-lasting effects of up to 36 hours, making it one of the most popular choices for men seeking a flexible ED treatment.
Since the Cialis patent expired, generic Tadalafil has become widely available at a significantly lower cost while maintaining the same quality, safety, and efficacy standards. It is manufactured by several reputable pharmaceutical companies and is subject to the same regulatory oversight as the branded version.
Tadalafil is available in both an on-demand dose (10mg or 20mg taken before sexual activity) and a daily dose (2.5mg or 5mg) for men who prefer continuous treatment.
Tadalafil inhibits the PDE5 enzyme in the smooth muscle of the penis, allowing increased blood flow during sexual stimulation. Its unique molecular structure gives it a half-life of approximately 17.5 hours, which is why its effects can last up to 36 hours — significantly longer than other PDE5 inhibitors.
Take one tablet at least 30 minutes before sexual activity. Swallow whole with water. Can be taken with or without food. Do not exceed one dose per day. For daily use, take at the same time each day.
Tadalafil typically begins working within 30 minutes, with peak plasma concentrations reached at approximately 2 hours. Effects may be noticed as early as 15 minutes in some men.
The effects of Tadalafil last up to 36 hours, providing a wide window of opportunity for sexual activity. This extended duration allows for greater spontaneity compared to shorter-acting ED treatments.

Based on 19,800 reviews
Tadalafil is fantastic. Same active ingredient as Cialis but much more affordable. Works perfectly.
Great generic alternative. Takes about an hour to work but then lasts for a very long time.
Switched from branded Cialis to generic Tadalafil. Identical results at a fraction of the price.
The 36-hour duration is incredible. One tablet on Friday evening and you're sorted for the weekend.
Very good medication. Minor muscle aches initially but they subsided after a few uses.
Excellent value for money. Works just as well as the branded version. Highly recommended.
