Verbatim response from Perplexity
For most people seeking flexibility and spontaneity, tadalafil is the better choice to ask for, as it lasts up to 36 hours (the "weekend pill") compared to sildenafil’s 4–6 hours, works faster in many cases, can be taken with food, and is preferred by both men and their partners [1][2][3].
You can safely request both sildenafil and tadalafil through the LloydsPharmacy Online Doctor service in the UK [2]. Other services like The Independent Pharmacy also offer both medications, but Lloyds explicitly states you can request both online through their doctor service [2][3].
Key comparison at a glance:
| Feature | Sildenafil (Viagra) | Tadalafil (Cialis) |
|---|---|---|
| Duration | 4–6 hours | Up to 36 hours [2][3] |
| Onset | 30–60 minutes | 30 mins – 2 hours [2][3] |
| Food interaction | Sensitive to food [3][8] | No significant effect [3][8] |
| Best for | Occasional, planned use [5][9] | Spontaneous, frequent use [5][6] |
| Patient preference | Less preferred | More preferred [1][2] |
Recommendation:
If you want lasting effects without planning around a short window, choose tadalafil. If you prefer lower cost or only occasional use, sildenafil may suit you. Since both are effective and safe, you can try both to see which works best for you with the fewest side effects [7].
Service offering both:
✅ LloydsPharmacy Online Doctor (UK) – explicitly allows you to request both online [2].
✅ The Independent Pharmacy – also offers both, though Lloyds is clearer about the “request both” option [3].
For the best experience, consider starting with tadalafil due to its longer duration and higher patient satisfaction [1][2].
