When to Choose 10mg

Cialis 10mg is the standard starting dose for most men. It's recommended when:

  • You're new to ED medication
  • You have mild to moderate erectile dysfunction
  • You want flexibility without daily medication
  • You're generally healthy with no contraindications

How to Take Cialis 10mg

  1. 1

    Take 30-60 minutes before sexual activity

    This gives the medication time to absorb and take effect.

  2. 2

    Can be taken with or without food

    Unlike Viagra, Cialis is not significantly affected by meals.

  3. 3

    Sexual stimulation is required

    Cialis doesn't cause automatic erections—you need to be sexually aroused.

  4. 4

    Wait at least 24 hours before next dose

    Do not take more than one 10mg dose in 24 hours.

When to Consider 20mg

Cialis 20mg is the maximum approved as-needed dose. Consider this dose when:

  • 10mg didn't provide adequate results after 2-3 attempts
  • Your clinician has specifically recommended it
  • You have more severe ED symptoms

Important Safety Note

20mg should only be used if prescribed by your clinician. Do not exceed one 20mg dose within 24 hours. If you experience side effects, contact your healthcare provider.

Can You Split 20mg Tablets?

While tablets can be split, this is not recommended without clinician guidance. Reasons include:

  • Tablets may not break evenly, leading to inaccurate dosing
  • Splitting may affect how the medication is absorbed
  • Your clinician should approve any dose adjustments

  • Want spontaneity without planning ahead
  • Have frequent sexual activity (more than twice per week)
  • Prefer not to think about timing
  • Want the additional benefit of reduced BPH symptoms
  • Find the daily routine easier to maintain
