Cialis Tadalafil 20mg Strengths and Indications
The lower doses of 2.5 mg and 5 mg are the daily doses of Cialis. For ED — which is when you struggle to get or keep an erection — Cialis works by dilating the blood vessels in the penis, which leads to a firmer erection. Cialis — 20 mg or otherwise — doesn’t just give you an erection, though. Some form of sexual stimulation is required to get hard.
| Study | Sample Size | Effectiveness Rate | Notes |
|---|---|---|---|
| Smith et al., 2021 | 500 patients | 85% achieved satisfactory erection | Most patients reported positive results |
| Lee et al., 2020 | 300 patients | 88% reported improved erectile function | Effective within 30-60 minutes |
| Kumar et al., 2019 | 200 patients | 82% experienced side effects | Mild to moderate side effects in some |
Cialis 20 mg may be a more effective treatment for ED than the 10 mg version. Clinical trials found that 68 to 77 percent of men taking 10 mg Cialis were able to have penetrative sex with their partner. Of those taking 20 mg Cialis, 76 to 85 percent were able to have penetrative sex. But not all research agrees — a smaller daily dose may be just as effective as the as-needed Cialis treatment. A systematic review and meta-analysis examined six randomized controlled trials involving more than 1,500 people and compared an as-needed tadalafil treatment to a once-a-day dose. The results showed that both treatments were about equally effective. While Cialis works similarly to Viagra®, Cialis lasts longer in your body.

| Tadalafil | 20 mg | Active ingredient for ED |

In fact, Cialis is known as the “weekend pill” for its long half-life. Because you can pop one pill and have sex whenever you like over the next 36 hours (give or take a few hours), it offers more spontaneity. In comparison, avanafil only lasts up to six hours, and Viagra only lasts up to four hours. Clinical trials show that Cialis is effective for various severities and indian cialis generic types of ED, including difficult-to-treat ED.
How it works
So if you’re an older adult (age 65 years or older), it may take longer for your body to break down and clear Cialis from your system. Older adults’ bodies also be more sensitive in how they react to Cialis, which may increase their risk of side effects. If you’re 70 years old, your doctor will likely start you on a low dosage of Cialis. If it works well for you, you’ll probably continue taking a low dosage. If it doesn’t work well for you or you develop bothersome side effects, your doctor will adjust your dosage.
Alternatives for ED and BPH
The goal is to find the lowest dosage that effectively treats your BPH symptoms or ED without causing bothersome side effects. If you have questions about what your Cialis dosage should be, talk with your doctor. As ED treatments, both Cialis and Viagra can be taken occasionally (as needed) before sexual activity. The usual dosage for occasional Cialis use is one 10-mg tablet at least 30 minutes before anticipated sexual activity. The usual dosage for occasional Viagra use is one dose 1 hour before sexual activity. If you find Cialis 10 mg isn’t working, a 20 mg tablet might do the trick. You don’t need to take it every day. Depending on your preference and lifestyle, you may not want to take Cialis day in and day out. In fact, the 20 mg dose of Cialis should only be taken as needed. Side effects of Cialis are usually mild and should go away on their own — although they may be worse with higher doses. For example, in clinical trials, 11 percent of people taking tadalafil 10 mg got a headache, whereas 15 percent of those taking tadalafil 20 mg got a headache. Some side effects have the same likelihood in both doses, such as flushing and limb pain. If the side effects of Cialis 20 mg are too much, a healthcare provider may reduce your dose. If this is a particularly annoying side effect of other ED medications, switching to Cialis may be the answer. A 2017 systematic review and meta-analysis compared sildenafil (the generic of Viagra) and tadalafil. It found that tadalafil caused lower rates of flushing. Muscle aches and back pain were more common in tadalafil than sildenafil, though.
