How Does Tadalafil Work?
Tadalafil belongs to a group of medicines called PDE5 inhibitors. It works by relaxing the blood vessels and improving blood flow to specific areas of the body, especially the penis during sexual stimulation.
By blocking the PDE5 enzyme, tadalafil helps maintain higher levels of cGMP, a natural substance that relaxes smooth muscles and increases blood flow. This makes it easier to achieve and maintain a firm erection when sexually aroused. Tadalafil does not increase sexual desire and only works with sexual stimulation.
How to Take Tadalafil
Take Tadalafil exactly as prescribed by your healthcare provider.
- Available strengths: 2.5 mg, 5 mg, 10 mg, and 20 mg tablets
- For erectile dysfunction, it can be taken 30 to 60 minutes before sexual activity or as a once-daily dose, depending on your prescription.
- Swallow the tablet whole with a glass of water.
- You can take it with or without food.
- Do not take more than one dose in 24 hours unless your doctor instructs otherwise.
Always follow your healthcare provider’s dosing instructions to achieve the best results.
What Is Tadalafil Used For?
Tadalafil is a prescription medication used to treat several medical conditions, including erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and erectile dysfunction associated with BPH. Certain formulations of tadalafil are also prescribed to manage pulmonary arterial hypertension (PAH).
Your healthcare provider will determine the appropriate dosage and treatment plan based on your specific medical condition and individual needs. Your healthcare provider will determine the correct tadalafil dosage based on your condition.
Missed Dose
If you take tadalafil once daily and miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue your regular schedule.
Do not take two doses at the same time to make up for a missed dose. If you take tadalafil only as needed before sexual activity, a missed dose is generally not a concern.
