According to Health Canada, Apo-Tadalafil is a prescription medication containing the active ingredient tadalafil, which is used to treat several conditions, including erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH). Proper administration is crucial for effectiveness and safety, and knowing how to use apo tadalafil correctly is essential for all patients.

Quick Summary

Apo-Tadalafil administration varies depending on the medical condition treated, with options for daily use or as-needed dosing based on a doctor's prescription. The medication is taken orally and is affected by certain foods and other drugs. This guide outlines proper administration methods and critical safety information.

Key Points

Prescription Only: Apo-Tadalafil is a prescription medication, and administration must be determined and monitored by a doctor based on your specific condition.
Take With or Without Food: Tablets can be taken with or without food, but should always be swallowed whole.
Avoid Grapefruit: Do not consume grapefruit or grapefruit juice, as it can increase the drug's concentration in your body.
On-Demand vs. Daily Administration: For erectile dysfunction, choose between on-demand (as-needed) or once-daily (routine) administration, as prescribed by your doctor.
Nitrate Interaction Risk: Never take Apo-Tadalafil with nitrate-containing drugs, as this can cause a life-threatening drop in blood pressure.
Watch for Side Effects: Be aware of common side effects and seek immediate medical help for serious symptoms like a prolonged erection, vision loss, or chest pain.
Timing Matters: For on-demand use, take the tablet as directed before sexual activity, with effects lasting up to 36 hours.

Understanding Apo-Tadalafil and Its Uses

Apo-Tadalafil is a generic version of the brand-name drug Cialis and belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. It works by increasing blood flow to specific areas of the body. For erectile dysfunction, it aids in achieving an erection with sexual stimulation. For BPH, it helps manage urinary symptoms by relaxing muscles in the prostate and bladder. For PAH, it helps relax blood vessels in the lungs. Your doctor's specific prescription is crucial as administration varies based on your condition.

Administration for Erectile Dysfunction (ED)

For ED, Apo-Tadalafil can be taken on-demand or once-daily, as directed by your healthcare provider.

On-Demand Administration (As Needed):

Taken before sexual activity, as prescribed by a doctor.
Effects can last for a significant period.
Requires sexual stimulation to work.

Once-Daily Administration:

Involves taking the medication consistently each day.
Provides a constant level for spontaneity.
Take around the same time daily as directed.

Administration for Benign Prostatic Hyperplasia (BPH) or Both ED and BPH

For BPH, with or without ED, the treatment involves a once-daily regimen as prescribed by a doctor.

This regimen helps with symptoms, but does not shrink the prostate.

Administration for Pulmonary Arterial Hypertension (PAH)

PAH requires a daily administration as prescribed by a doctor for both men and women.

This involves taking the prescribed amount once daily.

How to Take the Tablet

Method: Swallow tablets whole with water. Do not split or crush unless specifically instructed by your doctor.
Food: Can be taken with or without food.
Avoid: Do not consume grapefruit or grapefruit juice due to potential increased drug levels.

Frequently Asked Questions

Yes, if prescribed by your doctor. A once-daily regimen is typically used for managing benign prostatic hyperplasia (BPH), erectile dysfunction (ED), or both. Your doctor will determine if this approach is suitable for you.

For erectile dysfunction, Apo-Tadalafil typically starts working within 30 to 60 minutes after taking the tablet. However, the time may vary for each person. Importantly, sexual stimulation is still required for an erection to occur.

Moderate alcohol consumption is generally considered safe, but excessive drinking (more than five drinks) should be avoided. Combining too much alcohol with Apo-Tadalafil can significantly lower your blood pressure, leading to increased risk of dizziness, headaches, and fainting.

If you are on a once-daily regimen and miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take extra medication to make up for a missed one.

The most common side effects are headaches, flushing, indigestion (upset stomach), back pain, and muscle aches. These effects are usually mild to moderate and often resolve over time.

Yes, you must not take Apo-Tadalafil with any form of nitrate medication, which is often used for chest pain or heart problems. You should also avoid guanylate cyclase stimulators like riociguat. Always inform your doctor about all medications you are taking.
