Levitra vs Spedra: How They Actually Compare
Spedra (avanafil) and Levitra (vardenafil) are two PDE5 inhibitor tablets used to treat ED in the UK. Both are taken as-needed and have relatively rapid absorption, but there are some differences in timing, food effects and safety considerations. Levitra carries a specific QT-interval caution that Spedra does not, while a high-fat meal can have a greater effect on the absorption of Spedra. For adults in the UK considering ED treatment, these differences may help a prescriber decide which option is more appropriate.
They are genuinely more similar to each other than different, but the points where they diverge are worth knowing properly. Below, we compare onset time, duration, food interactions, side effects, effectiveness, common use cases, switching between the two, and the factors prescribers use when deciding which medicine may suit you better.
Key things to know
- Spedra and Levitra are more alike than most PDE5 comparisons, both short-acting with broadly similar durations.
- Spedra tends to act very slightly faster, though the difference is smaller than with some other comparisons in this class.
- Levitra carries a specific QT-interval caution that Spedra does not share.
- Both can be affected by a high-fat meal, but the effect on absorption is greater with Spedra than with vardenafil film-coated tablets.
- Neither has been shown more effective than the other in genuine head-to-head evidence

How Both Work
Spedra and Levitra are ed medicines used to treat erectile dysfunction, the active ingredient in Spedra is avanafil, while the active ingredient in Levitra is vardenafil. Both are prescription medication options in the PDE5 inhibitor class and work through the same underlying process. During sexual stimulation, they help increase blood flow into the erectile tissue of the penis by relaxing blood vessels and supporting the nitric oxide signal. An enzyme called PDE5 normally breaks this signal down, both medicines block PDE5, allowing the response to be sustained. Neither works automatically, so sexual stimulation is required for an erection. The genuine differences between them sit in timing, food sensitivity, and one specific safety consideration, not in this core mechanism.
How Fast Each One Works
Spedra can be taken approximately 15 to 30 minutes before sexual activity and is rapidly absorbed, with a median time to peak plasma concentration of around 30 to 45 minutes. Vardenafil is generally taken approximately 25 to 60 minutes before sexual activity, with peak plasma concentrations usually reached within 30 to 120 minutes and a median of around 60 minutes. This means Spedra has a somewhat faster absorption profile, although the practical difference between the two may be modest for some men.
How Long Each One Lasts
Both are relatively short-acting PDE5 inhibitors compared with tadalafil.
Vardenafil's clinical effects are generally used around a particular period of sexual activity, while Spedra is also taken as needed.
Although Spedra has a terminal half-life of approximately 6-17 hours, half-life should not be interpreted as the number of hours its erectile effect lasts.
Food Effects: A Real, if Smaller, Difference
Both are affected by a high-fat meal, but not to the same degree. Spedra's absorption is delayed by around 75 minutes with peak concentration reduced by around 39%, though the total amount eventually absorbed is not meaningfully reduced.
Levitra's food effect is comparatively milder, a high-fat meal delays absorption by around an hour with a smaller reduction in peak concentration, roughly 18 to 20%, and a moderate-fat meal has little clinically relevant effect on it at all.
Neither is genuinely food-independent, that distinction belongs to a different option in this class, but if food timing matters to you, Levitra's effect is somewhat gentler than Spedra's.
The Genuine Safety Difference: QT-Interval Caution
This is an important safety difference between the two medicines. Levitra carries a specific QT-interval caution that does not appear in the same way in Spedra's product information. A heart rhythm consideration relevant if you take certain antiarrhythmic medicines, have a related heart condition, or have specific electrolyte imbalances, and this should be reviewed with a doctor or prescriber rather than taken without consulting a healthcare professional, especially in patients with relevant heart history or other pre-existing conditions. This is not a caution shared by Spedra, which does not carry the same QT-related consideration. If you have any relevant heart rhythm history, or take medicines that affect heart rhythm, this is genuinely worth raising directly during an assessment, since it can meaningfully affect which of the two is appropriate for you.
Side Effects More Generally
Both medicines can cause side effects such as headache, flushing and nasal congestion, although their individual side-effect profiles differ. Spedra can also cause nausea and rash, while vardenafil can cause dizziness and visual disturbances. Back pain can occur with Spedra as well, so it should not be described as exclusive to another PDE5 inhibitor. Individual tolerability varies between people.
Individual tolerability can still differ between the two even though the general profile is similar, and neither has been shown to consistently cause fewer side effects overall, which is part of why trying a different option is a reasonable step if one does not suit you. Priapism means an erection lasting over 4 hours and requires urgent medical attention.

What If Neither Works Well Enough?
Since Spedra and Levitra are similar in profile, if one does not work as well as you'd like, it is genuinely worth trying the other before assuming the whole approach is not for you, because individual responses can differ in both effectiveness and side effects more than the general specifications suggest. If both fall short, that is useful information too, and points towards either other ED treatments or a different type of option (such as a non-drug treatment or a longer-acting tablet), or a fuller assessment of the underlying cause, rather than continuing to cycle through short-acting options indefinitely.
Is One Actually More Effective Than the Other?
Not according to the evidence available. There is no reliable basis for saying that Spedra or Levitra is universally more effective. Both have demonstrated efficacy in placebo-controlled clinical trials, but results from separate studies cannot be used as a direct head-to-head comparison. Individual response also varies, so one medicine may work better or be better tolerated for a particular person.
Does Individual Response Vary Between Them?
Yes. Even though both medicines work by inhibiting PDE5, people can respond differently to them. One may provide better erections or cause fewer troublesome side effects for a particular person. If the first option does not suit you, a prescriber may consider whether trying the other is appropriate.
A Few Practical Scenarios
A couple of situations can help clarify the decision beyond the spec comparison. If you have a diagnosed heart rhythm condition, are taking an antiarrhythmic medicine, or have had any related concerns flagged before, that is worth raising directly and may point towards Spedra rather than Levitra, since it does not carry the same QT-related consideration.
If food timing is a genuine day-to-day frustration, for instance if you often eat later or find it hard to plan meals around treatment, Levitra's comparatively milder food effect may make it marginally easier to work with than Spedra, even though neither is fully food-independent. If neither of these applies to you, the choice often comes down to which one you personally respond to and tolerate best, which usually means being open to trying either.
Tracking Whether Your Choice Is Working
Rather than judging a treatment from a single occasion, it can be useful to assess how consistently it works when it is taken correctly, at the prescribed dose and with enough time before sexual activity. If it does not work reliably after several correctly used attempts, speak to your prescriber rather than simply increasing the dose yourself.
Which Might Suit You Best
The choice depends on your medical history, other medicines, how you respond to treatment and practical factors such as food timing. If you have a heart rhythm condition or take medicines that affect the QT interval, the specific caution with Levitra is particularly important to discuss with a prescriber.
What About Viagra or Cialis?
If you are weighing up more than just these two, Viagra (sildenafil) sits in a broadly similar short-acting category to Spedra and Levitra, while Cialis (tadalafil) is genuinely different, food-independent and lasting up to 36 hours rather than a few. A wider comparison covering all four PDE5 inhibitors together goes into more detail if you want the fuller picture.
How a Prescriber Weighs This Up
An assessment typically considers your general health, any heart rhythm history or relevant medicines (given Levitra's specific QT consideration), how sensitive you are to food timing, whether you have tried either before, and the appropriate dosage. Spedra is available in 50mg, 100mg, and 200mg doses and the starting amount depends on the assessment. There is no default option that suits everyone, so the goal is to identify the right treatment and prescription for the individual, including when other medications or pre-existing conditions mean neither option should be taken without consulting a healthcare professional and different doses may need reviewing.
Switching Between Them
Trying the other on a separate occasion, with a prescriber's guidance, is a completely normal way to find what suits you, since individual response is not always predictable from the general profile of each medicine. Taking both together, or close together, is not advised, since they work through the same pathway and combining them adds risk without proven added benefit.
A Note on Cost
Pricing varies by strength, quantity and provider, so it is worth checking current, standard pricing directly rather than assuming one is reliably cheaper than the other. Cost comparisons can also shift when you look at generic versions of other ED medicines, while branded-only options may be priced differently. Since both are used in a broadly similar as-needed pattern, cost comparison here is more straightforward than with options that also offer a daily dosing structure.
