Choosing the right Cialis dose for erectile dysfunction is all about finding what works best for you and your needs. It comes in four different strengths: 2.5mg, 5mg, 10mg, and 20mg. The best dosage depends on how often you plan to use it and how your body responds to the medication, which can vary significantly between individuals.

On this page, you will find essential information on how to choose the right strength of Cialis for your specific situation and how frequently it can be administered.

What Cialis dosages are available?

Cialis is available in four dosages in the UK:

  • 2.5mg: small white pills with ‘2.5mg’ inscribed on them
  • 5mg: small light orange pills with ‘5mg’ indicated
  • 10mg: larger light orange pills with ‘10mg’ imprinted
  • 20mg: larger dark orange pills marked with ‘20mg’

The dosage of Cialis signifies the amount of the active component, tadalafil, contained within the pill. Lower doses (2.5mg and 5mg) are primarily intended for daily use, while the higher doses (10mg and 20mg) are suitable for use as needed, typically taken at least 30 minutes before anticipated sexual activity.

The standard dose for Cialis Daily is usually 5mg, while 10mg is commonly considered the starting dosage for on-demand use.

About Cialis 10mg

The 10mg dose is generally recommended for those who are considering sexual activity up to three times a week and have not previously tried Cialis. This is often labeled as the ‘standard dose’:

  • Taken when needed (on demand), at least half an hour prior to sexual activity
  • Effects can last up to 36 hours
  • Suitable for most users, with a lower likelihood of side effects compared to higher dosages
  • Available in pack sizes of 4, 8, 12, 16, and 28 tablets

About Cialis 20mg

If the 10mg dosage does not achieve the desired effects, you might consider increasing to 20mg:

  • Similar to 10mg, it is taken on demand, at least half an hour before planned sexual activity
  • Also lasts up to 36 hours
  • May be effective for those who found insufficient results with the 10mg dosage, but has a higher potential for side effects
  • Pack sizes are the same as for the 10mg option

About Cialis Daily 2.5mg and 5mg

If you engage in sexual activity more than three times per week, opting for Cialis Daily may be advantageous. It is primarily offered in two doses:

  • 5mg is the standard daily dose, taken at the same time every day
  • By adhering to a consistent dosing schedule, you should experience desired effects consistently
  • If side effects occur, consider switching to the lower 2.5mg dose
  • Both dosages typically come in packs of 28 tablets

How often can you take a dose of Cialis?

All doses can be taken up to once a day; however, you should never exceed one tablet within a 24-hour period. Consider switching to Cialis Daily if:

  • You find yourself taking the higher doses (10mg or 20mg) more than three times per week
  • You take supplemental doses before the 24-hour period has elapsed
  • The effects of Cialis wear off before 24 hours and you desire to engage in sexual activity again

What if my current dose isn’t working?

  • If you are taking 2.5mg or 10mg without experiencing side effects, increasing your dosage could be beneficial, but consult your healthcare provider first.
  • If you're on a daily 5mg dose, you might consider trying a higher on-demand dosage.

If 20mg of Cialis remains ineffective, it may be time to explore alternative medications or other treatments like lifestyle changes, therapy, or even a penis pump. Never combine Cialis with other ED medications or exceed recommended dosages without professional advice.

How do Cialis dosages compare with Viagra ones?

Cialis and Viagra contain different active ingredients, which means their respective dosages cannot be directly compared. For instance, 20mg of Viagra does not equate to 20mg of Cialis in terms of effects or duration.

Conclusion

This article has detailed the various dosages of Cialis and important considerations when selecting the appropriate strength for your needs. Begin with a lower dose, regardless of whether you choose daily or on-demand options, and always consult your healthcare provider for guidance tailored to your situation.

Do not attempt to modify your dosage without prior consultation with your doctor. For questions regarding dosage effectiveness or other concerns, please reach out to a medical professional.
