Which pill is the most effective?

All of these medications are about as effective as each other.

Even though some of the dosages for certain treatments appear higher than other treatments, that does not mean that some treatments are stronger than the others.

For each of these medications, the chance of it working is slightly higher as the dosage goes up, but so is the risk of side effects. We recommend starting on the standard dose and only changing to a higher one if the standard dose didn’t work and you didn’t get any serious side effects. You should only change doses with the help of a doctor.

You may need to try more than one tablet to find one that works for you. Never take more than one erectile dysfunction tablet of any kind within 24 hours. Also, don’t switch medications or change the dose of your treatment without the help of a doctor.

Out of Viagra, Cialis, and Levitra, Viagra works out the cheapest, if you order from us.

Other erectile dysfunction medications may be cheaper:

  • If you have sex on up to 3 different days a week, then the most cost effective treatment for you could be Sildenafil. We offer Sildenafil from just £15.00 for 4x 50mg tablets, or £2.79 per pill if you buy 28x 25mg or 50mg tablets.
  • If you have sex on more than 3 different days a week, then the most cost effective treatment might be Cialis Daily. At £75.00 for 28 pills it works out as £2.68 per pill, but you have to take one every day, so they might not last you as long if you’re not having sex that often.

Which tablet has the least side effects?

Less than 2% of men who use Viagra, Cialis, or Levitra will get side effects. The dose of the medication you’re taking will also affect how likely you are to get side effects.

Lower dosages of medications are less likely to give you side effects. We normally recommend you try standard doses first to see if you get any side effects before thinking about switching to lower dosages. Never change dosages without the help of a doctor.

Which tablet works the fastest?

Cialis works the fastest out of Viagra, Cialis, and Levitra. Cialis starts working in just 30 minutes, while Viagra and Levitra can take up to an hour to start working after you take it.

If you don’t want to take a pill every time you want to have sex, you can try Cialis Daily. Cialis Daily is a pill that you take every day, and helps you get an erection whenever you want to have sex.

Which tablet lasts the longest?

Cialis is the longest lasting tablet out of Viagra, Cialis, and Levitra. Cialis can last up to 36 hours, which is why it’s sometimes known as the ‘weekend’ pill. Viagra and Levitra can last up to 6 hours.

Cialis Daily is always in effect. As long as you keep taking your daily tablet, Cialis Daily will keep working.

Just because the effect of these pills can last for hours does not mean that you will have an erection for that long. These medications can help you get and keep an erection when you are aroused, but they will not give you an erection for the full time that they are effective
