What's in the iQ Doctor ED Advance Pack
The ED Advance Pack contains the 4 main medicines used to treat erectile dysfunction:
Sildenafil 100mg: 4 tablets
Tadalafil 20mg: 4 tablets
Spedra 200mg: 4 tablets
Vardenafil 20mg: 4 tablets
We're committed to providing high-quality, fully licensed medication and a range of options to help you manage your ED symptoms.
Spedra 200mg, Tadalafil 20mg, Sildenafil 100mg and Vardenafil 20mg are all prescription medicines used to treat ED in men. They work by increasing blood flow to the penis, resulting in a firmer and longer-lasting erection. Each medicine has its own benefits and cautions. It's essential to understand them before you take any of them, so you can find the best match for you.
Spedra
Spedra 200mg contains the active ingredient Avanafil. It works by relaxing the blood vessels in the penis, which allows more blood to flow in. Spedra 200mg is fast-acting and starts to work within 15 to 30 minutes of taking it. Always take Spedra 200mg as directed by your healthcare provider, and never exceed the recommended dose.
Vardenafil
Vardenafil 20mg contains the active ingredient Vardenafil. It's also known by its brand name, Levitra. Vardenafil 20mg is fast-acting and starts to work within 25 to 60 minutes of taking it. Always take Vardenafil 20mg as directed by your healthcare provider, and never exceed the recommended dose.
Tadalafil
Tadalafil 20mg contains the active ingredient Tadalafil. It's also known by its brand name, Cialis. Tadalafil 20mg is longer-acting, with effects lasting up to 36 hours. Always take Tadalafil 20mg as directed by your healthcare provider, and never exceed the recommended dose.
Sildenafil
Sildenafil 100mg contains the active ingredient Sildenafil. It's also known by its brand name, Viagra. Sildenafil 100mg is fast-acting and starts to work within 30 to 60 minutes of taking it. Always take Sildenafil 100mg as directed by your healthcare provider, and never exceed the recommended dose.
ED Advance Pack considerations
These medicines aren't suitable for everyone. Before taking any of them, check with your healthcare practitioner that they're suitable for you. When you complete our online questionnaire, tell us about any medical conditions you have, including allergies, heart conditions and liver or kidney problems. Answer as honestly and as accurately as you can.
We strongly advise that you don't take more than one of these medicines at the same time. We also strongly advise that you leave at least 36 hours after taking Tadalafil, or at least 24 hours after taking any of the others, before you take a different one. These medicines are all designed to increase blood flow to the penis. Taking them together, or too close to each other, can lead to a dangerous drop in blood pressure.
If you have symptoms of erectile dysfunction and you're unsure which medicine is right for you, you may want to consider this pack. It contains a selection of the most prescribed ED medicines, so you can try each one and find the one that works best for your body.
Everyone is different. By trying each medicine, you can assess how well it works for you and any side effects it causes. This makes it easier to choose the right medicine for your needs. The ED Advance Pack is an affordable and convenient way to explore different options (saving almost £15 when you buy as a pack), so you can find the medicine that suits you best.
