How ED treatment works in your body.

Increases blood flow

Increases blood flow

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

Increase erections

Increase erections

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.

Viagra vs Cialis: Key Treatment Differences

How British Viagra and Cialis Work

Both British Viagra (sildenafil) and Cialis (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. However, these treatments differ significantly in their duration and onset times, making one potentially more suitable than the other depending on your lifestyle preferences.

Timing and Duration Comparison

British Viagra typically begins working within 30-60 minutes of taking and maintains effectiveness for 4-6 hours. This makes it suitable for planned sexual activity within a specific timeframe. Cialis, conversely, can remain effective for up to 36 hours, earning it the nickname "the weekend pill" due to its extended duration. Cialis may take slightly longer to start working, sometimes up to 2 hours, but offers greater spontaneity once active.

Dosage and Administration Differences

British Viagra is available in 25mg, 50mg, and 100mg tablets, with 50mg being the typical starting dose. It should be taken approximately one hour before sexual activity, with a maximum of one dose per 24 hours. Cialis comes in 2.5mg, 5mg, 10mg, and 20mg options, with two dosing strategies available: on-demand dosing (10mg or 20mg taken before activity) or daily low-dose treatment (2.5mg or 5mg taken regularly).

Food and Alcohol Interactions

British Viagra's effectiveness can be reduced by fatty meals, which may delay absorption and onset of action. Taking it on an empty stomach or with a light meal typically provides optimal results. Cialis is less affected by food intake, making it more convenient for those who prefer not to plan around meals. Both medications can interact with alcohol, and excessive drinking may reduce effectiveness while increasing the risk of side effects.

Cost Considerations and Generic Options

When comparing costs, generic sildenafil offers significant savings compared to branded British Viagra while containing the identical active ingredient. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, allowing for budget-conscious decisions without compromising treatment quality. Generic tadalafil is also available as a cost-effective alternative to branded Cialis.

Side Effects and Tolerability

Both treatments share similar potential side effects, including headaches, facial flushing, indigestion, and nasal congestion. However, some men may tolerate one medication better than the other. Cialis may cause muscle aches or back pain in some users, while Viagra might cause more visual disturbances. The longer duration of Cialis means any side effects experienced may also persist longer.

Lifestyle Suitability

Your choice between British Viagra and Cialis often depends on sexual activity patterns and lifestyle preferences. Viagra suits those who prefer planned intimate encounters and don't mind timing medication around meals. Cialis appeals to men seeking greater spontaneity and flexibility, particularly those in relationships where sexual activity frequency varies or timing is unpredictable.

What you need to know about erectile dysfunction

It's one of the most common conditions we treat, and one of the most treatable.

What is Erectile Dysfunction?
ED means finding it hard to get or keep an erection firm enough for sex. It's not unusual to have an off night; the point at which it's worth doing something is when it's happening regularly, or when it's starting to bother you.
How will I feel when I take ED medication?
For most men, nothing feels different day to day. The medication works in the background — when you're sexually aroused, it helps blood flow where it's needed, so erections come more easily and last longer. It doesn't cause arousal on its own. Some men notice mild, short-lived effects like a headache, facial flushing or a stuffy nose, which usually pass as the dose wears off.
Why do I need a prescription for ED medication?
ED treatments are prescription-only medicines in the UK because they aren't suitable for everyone — for example, alongside certain heart conditions or medications like nitrates. That's why we ask you to complete a short online consultation first. A UK-registered prescriber reviews your answers to make sure your chosen treatment is safe and right for you before it's dispensed.
