Choosing between Viagra (sildenafil) and tadalafil for erectile dysfunction treatment can be challenging. Both are proven PDE5 inhibitors that help improve blood flow to achieve and maintain erections when sexually aroused. Understanding the key differences in duration, onset time, and suitability can help you make an informed decision. EverydayMeds offers both branded Viagra and cost-effective generic sildenafil options following a clinical consultation with our UK-licensed prescribers.

When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.
Both Viagra (sildenafil) and tadalafil belong to a class of medications called PDE5 inhibitors. They work by blocking the phosphodiesterase type 5 enzyme, which increases blood flow to the penis during sexual arousal. Neither medication causes automatic erections - sexual stimulation is still required for effectiveness.
The most significant difference between these treatments lies in their duration of action. Viagra typically remains effective for 4-6 hours after taking, making it suitable for planned intimate moments. Tadalafil, conversely, can remain effective for up to 36 hours, earning it the nickname "the weekend pill" due to its extended window of effectiveness.
Both medications generally take 30-60 minutes to become effective, though this can vary between individuals. Food intake, particularly fatty meals, may delay the onset of both treatments.
Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg strengths. Most men start with the 50mg dose, which can be adjusted up to 100mg or down to 25mg based on effectiveness and any side effects experienced. Tadalafil comes in 10mg and 20mg strengths for on-demand use, with 10mg being the typical starting dose.
Generic sildenafil offers identical active ingredients to branded Viagra at a significantly lower cost. At EverydayMeds, patients can choose between the branded Viagra option or the more economical generic sildenafil during checkout, both requiring the same clinical assessment process.
Both treatments share similar side effect profiles, commonly including headaches, flushing, nasal congestion, and indigestion. However, some men may respond better to one medication over the other. Tadalafil may be preferred by those seeking spontaneity due to its longer duration, while Viagra might suit those preferring shorter-acting medication.
Both medications are contraindicated for men taking nitrate medications (such as GTN spray), those with severe heart conditions, recent stroke or heart attack, or severe liver problems. A thorough clinical assessment with our UK-licensed prescribers helps determine suitability and identify any potential drug interactions.
The decision between Viagra and tadalafil often comes down to lifestyle preferences and individual response. Some men prefer the shorter duration of Viagra for planned encounters, while others value tadalafil's extended effectiveness for greater spontaneity. Both options require a prescription following consultation with our qualified healthcare professionals.
