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.

Comparing Sildenafil Tablet Strengths and Effectiveness

Understanding Sildenafil Dosage Options

Sildenafil tablets are available in three main strengths: 25mg, 50mg, and 100mg. Each strength contains the same active ingredient that helps improve blood flow to treat erectile dysfunction, but the concentration differs to accommodate varying individual needs and tolerances.

50mg Sildenafil: The Standard Starting Dose

Most men begin treatment with sildenafil 50mg tablets, which clinical studies show provides effective results for the majority of patients. This moderate strength typically works within 30-60 minutes and may help maintain effectiveness for up to 4-6 hours. Healthcare providers often recommend starting with 50mg because it balances effectiveness with a lower risk of side effects compared to higher doses.

The 50mg strength allows healthcare professionals to assess how well you respond to treatment before considering dose adjustments. Many men find this dose provides sufficient improvement in erectile function without experiencing troublesome side effects.

25mg Sildenafil: Lower Strength Option

Sildenafil 25mg represents the lowest available dose and may be suitable for men who experience side effects with higher strengths or those taking certain medications that could interact with sildenafil. This dose might also be recommended for older adults or those with underlying health conditions that could affect how the medication is processed.

While 25mg provides a gentler approach to treatment, it may not be sufficient for all men to achieve desired results. Your prescriber can help determine if this lower dose meets your needs or if adjustment to a higher strength would be more appropriate.

100mg Sildenafil: Maximum Strength

The 100mg dose represents the highest recommended strength of sildenafil for erectile dysfunction treatment. This option may be considered for men who don't achieve adequate results with 50mg and can tolerate the medication well. However, higher doses can increase the likelihood of side effects such as headaches, flushing, or dizziness.

Moving to 100mg should only occur under medical guidance and after trying lower doses. The maximum recommended frequency remains one tablet per 24-hour period, regardless of strength.

Generic Sildenafil vs Branded Options

Generic sildenafil tablets contain the same active ingredient as branded alternatives but typically cost significantly less. Both undergo rigorous testing to ensure identical safety and effectiveness profiles. At EverydayMeds, patients can choose between generic sildenafil and branded Viagra during checkout, allowing you to select based on personal preference and budget considerations.

The choice between generic and branded options doesn't affect dosing recommendations or clinical effectiveness. Both follow the same usage guidelines and require identical medical assessments before prescribing.

Important Safety Considerations

Regardless of strength chosen, sildenafil tablets should never be taken with nitrate medications due to dangerous blood pressure interactions. Always inform your healthcare provider about all medications and health conditions during consultation. Side effects may be more pronounced with higher doses, making it important to start with appropriate strengths and adjust gradually if needed.

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.
