Correct dosage for Cialis
Correct dosing is crucial for any medication to maximize its benefits while minimizing potential side effects. The dosage for Cialis (tadalafil) depends on its intended use, whether for erectile dysfunction (ED), benign prostatic hyperplasia (BPH), or both. Here's a general guide, but always consult with a healthcare provider to determine the most appropriate dosage for your individual circumstances.
1. Cialis for Erectile Dysfunction (ED):
On-demand use:
- Starting dose: 10 mg taken before anticipated sexual activity.
- Adjustment: Depending on efficacy and tolerance, the dose can be increased to 20 mg or decreased to 5 mg. It's essential not to take Cialis more than once a day.
Note: The effect of Cialis may last up to 36 hours, which is why it's sometimes called the "weekend pill."
Daily use:
- Starting dose: 2.5 mg taken once a day, regardless of the timing of sexual activity.
- Adjustment: Depending on efficacy and tolerance, the dose can be increased to 5 mg daily.
2. Cialis for Benign Prostatic Hyperplasia (BPH):
Daily use:
Recommended dose: 5 mg taken at approximately the same time every day.
3. Cialis for Both ED and BPH:
Daily use:
Recommended dose: 5 mg taken at approximately the same time every day.
Special Populations:
- For elderly patients: No dose adjustment is typically necessary based on age alone. However, due to potential physiological changes in the elderly, they should start at the lower end of the dosing range.
- For patients with renal impairment: For patients with moderate renal impairment, the dose for ED should not exceed 10 mg once daily, and for BPH, 5 mg daily.
- For patients with hepatic impairment: For patients with mild to moderate liver dysfunction, the maximum dose should not exceed 10 mg. Cialis is not recommended for patients with severe hepatic impairment.
Interactions to Be Aware Of:
- With nitrates: Cialis should not be taken with any form of nitrate medication, as this combination can cause a significant drop in blood pressure.
- With alpha-blockers: Caution should be exercised when using Cialis and alpha-blockers together, as this combination can lead to low blood pressure.
In Conclusion:
Always take Cialis exactly as prescribed by your healthcare provider. If you experience any side effects or have questions about your dosage, consult with your provider promptly. Avoid taking more than the recommended dose, and always consider potential drug interactions.
