What Cialis dosages are available?

Cialis is available in four distinct dosages:

  • 2.5mg: Small white pills clearly labeled '2.5mg'
  • 5mg: Small light orange pills clearly labeled '5mg'
  • 10mg: Large light orange pills clearly labeled '10mg'
  • 20mg: Large dark orange pills clearly labeled '20mg'

The medication primarily contains the active ingredient tadalafil. Generally, lower doses (2.5mg and 5mg) are prescribed for daily usage, while the 10mg and 20mg strengths are intended for 'on demand' use. This means they should be taken at least 30 minutes prior to anticipated sexual activity rather than on a daily basis.

The maximum recommended dosage for erectile dysfunction in the USA is 20mg. It's crucial to exercise caution, as higher doses can increase the risk of potential side effects.

About Cialis 10mg

The 10mg dosage of Cialis is frequently recommended for individuals who engage in sexual activity up to three times a week and are new to this medication. Often regarded as the 'standard dosage,' here are some crucial details:

  • Cialis 10mg should be taken as needed, typically at least 30 minutes before sexual intercourse.
  • The effects may last for up to 36 hours, offering a flexible window for sexual activity.
  • This dosage generally proves effective for most users, with a lower risk of side effects when compared to higher strengths.
  • Available in various pack sizes (4, 8, 12, 16, and 28 tablets), it can be easily sourced from licensed pharmacies.

About Cialis 20mg

If the 10mg dose does not produce the anticipated results without side effects, individuals may contemplate increasing their dosage to 20mg. Important considerations regarding Cialis 20mg include:

  • This dosage is taken as required, at least 30 minutes ahead of sexual activity.
  • It also provides effects that may last for up to 36 hours.
  • This strength may cater to those who require a more robust dose yet may heighten the risk of side effects.
  • Like the 10mg, it is also available in the same pack sizes.

About Cialis Daily 2.5mg and 5mg

If sexual activity happens more than three times a week, a daily regimen of Cialis may be advantageous. This comes in two doses: 2.5mg and 5mg.

  • The 5mg dose is typically recommended to be consumed once daily at the same time each day.
  • If side effects present issues with the 5mg dose, transitioning to the 2.5mg dose may help, which carries a somewhat lower risk of side effects.
  • Both daily dosages are packaged conveniently, available in packs of 28 tablets.

How often can you take a dose of Cialis?

Cialis can be taken up to once each day; however, it is imperative that no more than one tablet is consumed within a 24-hour period. If you find that you're using higher doses (10mg or 20mg) more than three times weekly, consider opting for the Cialis Daily option.

Other indicators suggesting a switch may include:

  • Taking on-demand doses multiple times within a 24-hour period, which could increase the risk of side effects.
  • If you find that the effects wear off before the 24-hour mark and you wish for additional sexual activity.

What if my current dose isn’t working?

  • If you are taking 2.5mg or 10mg without experiencing side effects, discuss with your doctor the possibility of increasing your dosage.
  • If you are using a daily 5mg dose, exploring higher on-demand options following consultation with your healthcare provider could potentially enhance outcomes.

If the 20mg dose of Cialis yields no results, you may need to consider alternative treatment options. These could include lifestyle changes, counseling, or therapy, but always consult with your healthcare provider before combining Cialis with other erectile dysfunction medications.

How do Cialis doses compare with Viagra ones?

Cialis and Viagra contain different active ingredients and have various mechanisms of action. Therefore, directly comparing their dosages isn't practical. For example, 20mg of Viagra does not equate to the same efficacy as 20mg of Cialis, given their distinct ways of functioning in the body.
