Taking two 2.5 mg tablets of Tadalafil (total 5 mg) instead of one 2.5 mg tablet does not necessarily mean you will get a quicker, stronger, or harder erection. Here's why:

• Dosage and Effect: Tadalafil's effectiveness depends on the prescribed dose and how your body responds. The 2.5 mg dose is usually for daily use to maintain steady levels, not for immediate effect.

• Onset of Action: Tadalafil typically takes about 30 minutes to 2 hours to work, regardless of doubling a low dose.

• Safety: Taking more than the prescribed dose can increase the risk of side effects like headache, dizziness, or low blood pressure.

• Consult Your Doctor: Always follow your healthcare provider's instructions. If you feel your current dose isn't effective, discuss it with your doctor rather than adjusting the dose yourself.

In summary, doubling the 2.5 mg dose without medical advice is not recommended and may not improve your erection quality or speed. Your doctor can guide you on the appropriate dose and timing for your needs.

Please consult a urologist or specialist doctor for personalized advice and safe management of erectile dysfunction.
