Keep reading to learn more about Viagra and Viagra Connect and how they differ.
What’s the difference between Viagra and Viagra Connect?
As Viagra and Viagra Connect contain the same active ingredient sildenafil, and work in the same way, the only real differences between the treatments are:
- their pack sizes
- dosages
- whether they’re available over the counter
- cost
Determining which is right for you will depend on whether you’ve tried an ED treatment before, the severity of your ED, your medical history (some people need to start on 25mg rather than 50mg), and personal preference.
Viagra and Viagra Connect similarities
The main similarities between Viagra and Viagra Connect are:
- both are phosphodiesterase type 5 (PDE-5) inhibitors as they contain the same active ingredient, sildenafil, which can also be found as a generic tablet
- they both treat erectile dysfunction (ED) when taken 30 minutes before you plan to have sex
- each medication lasts for around 4 hours
- they are manufactured by the same company, Pfizer
Viagra and Viagra Connect differences
As well as having similarities, there are a few important differences between Viagra and Viagra Connect, such as:
Doses
Viagra Connect is only available at a 50mg dose. This is the typical starting dose of Viagra or sildenafil. Viagra is available in 25mg, 50mg, and 100mg.
Viagra 25mg
25mg is only available on prescription and is usually recommended for people taking certain medications, such as protease inhibitors for the treatment of HIV or alpha-blocker therapy for the treatment of high blood pressure or prostate enlargement. There may also be certain medical conditions which mean you need a lower dose, or you may need a lower dose if you get side effects on the 50mg dose.
In these cases, a pharmacist will not be able to provide Viagra Connect and you’ll need to take it under the supervision of a doctor.
Viagra 100mg
100mg is only available on prescription. If you have tried 50mg of Viagra or Viagra Connect 8 different times, and it’s not working properly for you, such as its effects are not lasting long enough for sex, a doctor may prescribe 100mg tablets to try.
Prescription
Viagra Connect is available over the counter, while Viagra requires a prescription. You will still need to answer a few questions about your health when speaking to a pharmacist to make sure Viagra Connect is safe and suitable for you before you can purchase it.
You can get either online, from regulated services like Asda Online Doctor, after answering a short medical questionnaire, if you’d prefer not to speak to someone in person.
You should still talk to your doctor if you are using ED tablets, as there may be another treatment that’s more suitable for your needs that requires a prescription. ED can also be an underlying symptom of another health condition, so you may also need further tests to determine the cause of your symptoms.
Pack sizes
Viagra Connect is available in packs of 2, 4, 8, 12, 16, or 28 tablets. Viagra’s smallest pack size is 4 tablets and can be found in 4, 8, 12, 16, 24, 28, 32, or 64 tablets.
Pack sizes will depend on the pharmacy you purchase from but Viagra Connect is typically given in smaller pack sizes because it's an over-the-counter medication.
Price
Viagra Connect and Viagra usually differ in price. Prices depend on where you get them, but Viagra tends to be slightly more expensive for a pack size of 4, but higher pack sizes are more similar in price.
