Levitra Extra Dosage contains 20 mg of vardenafil, twice the standard 10 mg dose. It is used to treat erectile dysfunction and works by increasing blood flow to the penis during sexual stimulation. The effects typically last up to 6 hours.
It is recommended to take Levitra Extra 30-60 minutes before sexual activity. Common side effects include headache, flushing, and nasal congestion.
When you see Levitra extra dosage, you’re looking at a 20mg tablet of Levitra - a brand name for vardenafil, a phosphodiesterase‑5 (PDE5) inhibitor designed to treat erectile dysfunction (ED). The higher dose is meant for men who need a stronger response or who didn’t get enough benefit from the standard 10mg tablet.
Vardenafil blocks the PDE5 enzyme in the penile tissue. By doing so, it boosts the buildup of cyclic guanosine monophosphate (cGMP), which relaxes smooth muscle and allows blood to fill the corpora cavernosa. The result is an erection that can be maintained for several hours, provided there’s sexual stimulation.
*Prices fluctuate; generic options can be cheaper.
Below are the most frequently prescribed ED pills that compete with Levitra Extra Dosage.
Viagra - the first FDA‑approved oral ED treatment, containing sildenafil.
Cialis - a tadalafil formulation that offers a long‑lasting window.
Stendra - marketed as avanafil, known for a rapid onset.
Generic vardenafil tablets, sold under various pharmacy brands, provide the same active ingredient as Levitra but usually at a lower cost.
| Attribute | Levitra Extra (20mg) | Viagra (50‑100mg) | Cialis (20mg) / Daily (2.5‑5mg) | Stendra (100‑200mg) | Generic Vardenafil (10‑20mg) |
|---|---|---|---|---|---|
| Active ingredient | Vardenafil | Sildenafil | Tadalafil | Avanafil | Vardenafil |
| Typical dose | 20mg | 50‑100mg | 20mg (as needed) or 2.5‑5mg daily | 100‑200mg | 10‑20mg |

Need a quick spark? Stendra’s 15‑minute onset gives the fastest start, making it a good choice for spontaneous moments.
If you like planning ahead and want a long window, Cialis’s 36‑hour effect means you can be ready for any occasion without timing the pill.
When you’ve tried the standard 10mg Levitra and still feel the effect is weak, the 20mg extra dosage may close that gap without switching drugs.
Budget‑conscious users often opt for generic vardenafil, which delivers the same mechanism at a fraction of the brand price.
All of these PDE5 inhibitors share contraindications. Never combine them with nitrates (common in heart‑pain medication) - the mix can cause a dangerous drop in blood pressure.
Men with severe cardiovascular disease, uncontrolled hypertension, or certain eye conditions should consult a doctor before trying any of these pills.
Alcohol in moderation usually doesn’t interfere, but heavy drinking can blunt the effect and raise side‑effect risk.
Choosing the right ED medication boils down to three questions: How fast do you need it to work? How long do you want the effect to last? What price range fits your budget? Levitra Extra Dosage shines when you need a stronger, mid‑range window without committing to a daily pill. Alternatives like Viagra, Cialis, and Stendra each bring a unique balance of speed, duration, and cost. Talk with a healthcare professional to pinpoint the best fit for your health profile.
A moderate amount of alcohol usually doesn’t cancel the effect, but drinking heavily can lower blood pressure and make side effects like dizziness more likely. Keep alcohol to one or two drinks and see how your body reacts.
The 20mg tablet is intended for occasional use, not daily dosing. Daily users typically choose Cialis at a low dose (2.5‑5mg) because its safety profile supports long‑term intake.
Both contain the same active ingredient, vardenafil, and work identically. The main difference lies in cost and inactive fillers; some users report a slightly different feel, but clinical effectiveness is the same.
Both are prescription drugs, so a doctor’s approval is required. Switching is common, but the physician will need to confirm dosage, health status, and any drug interactions.
Seek emergency medical care immediately. A prolonged erection (priapism) can damage penile tissue if not treated promptly.

October 3, 2025 AT 14:47Reading this glossy showdown feels like watching a carnival of chemists trying to out‑shine each other with flashy numbers, but the truth is far less dazzling – the 20 mg Levitra extra is simply a higher‑dose version of a drug that already does its job, and inflating the price tag to $45‑$55 is a shameless cash grab that preys on vulnerable men desperate for a quick fix. The side‑effect profile doesn't magically improve with a bigger pill; you still get the same headaches, flushing, and nasal congestion, only amplified for some unlucky users. And let’s not ignore the fact that most of these comparisons ignore the long‑term cardiovascular risks that are glossed over in glossy marketing copy. In short, this so‑called “extra” dosage is a gimmick, not a breakthrough, and the real winners here are the pharmaceutical giants cashing in on our insecurities.
