When choosing between ED treatments, understanding how long each medication works is crucial for planning intimacy. Viagra (sildenafil) typically lasts 4-6 hours, whilst Spedra (avanafil) offers a shorter 3-5 hour window but faster onset. Both require sexual stimulation to be effective and should only be taken once per day. EverydayMeds offers both branded Viagra and generic sildenafil options through our confidential online consultation service.

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.
Viagra (sildenafil) typically remains effective for 4-6 hours after taking a dose, making it one of the longer-lasting ED treatments available. The medication reaches peak concentration in your bloodstream within 1-2 hours, though you may notice effects beginning 30-60 minutes after taking it. This extended duration allows for greater spontaneity in intimate relationships.
Spedra (avanafil) offers a slightly shorter duration of 3-5 hours but compensates with rapid onset. Many patients find Spedra works within 15-30 minutes, making it suitable for more spontaneous encounters. However, the shorter duration may require more precise timing.
Both Viagra and Spedra belong to the PDE5 inhibitor class, blocking the enzyme that restricts blood flow to the penis. Neither medication causes automatic erections - sexual arousal remains necessary for effectiveness. The key difference lies in how quickly each drug is absorbed and metabolised by your body.
Food intake significantly affects both medications. Fatty meals can delay Viagra's onset by up to an hour, whilst Spedra shows less interaction with food. If you're planning a romantic dinner, Spedra may offer more reliable timing, though both medications work best on an empty stomach.
Viagra is available in 25mg, 50mg, and 100mg strengths, with 50mg being the standard starting dose. Most patients find 50mg provides adequate duration and effectiveness, though some may require dose adjustments based on response and tolerability.
Spedra comes in 50mg, 100mg, and 200mg tablets, with 100mg as the typical starting dose. The higher starting dose reflects differences in bioavailability rather than superior potency. Your prescriber will recommend the most appropriate dose based on your medical history and treatment goals.
At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout. Generic sildenafil contains the same active ingredient as Viagra and offers identical duration and effectiveness at a significantly lower cost. This makes long-term treatment more affordable whilst maintaining the same 4-6 hour duration.
Spedra currently has no generic equivalent in the UK, making it the more expensive option. When comparing value for money, many patients find generic sildenafil provides excellent effectiveness at a fraction of the cost of branded alternatives.
Choosing between Viagra's longer duration and Spedra's rapid onset depends on your personal preferences and lifestyle. If you value extended effectiveness windows and cost-effectiveness, Viagra or generic sildenafil may be ideal. For those prioritising speed of action and shorter commitment periods, Spedra could be more suitable.
Many patients find the 4-6 hour duration of Viagra provides optimal balance between effectiveness and flexibility. The longer window reduces pressure to time intimate moments precisely whilst ensuring the medication remains active when needed.
