Tadalafil

What Tadalafil Is Used For

Tadalafil is primarily used to treat erectile dysfunction (ED) in men, helping to achieve and maintain an erection during sexual activity. It is also prescribed for benign prostatic hyperplasia (BPH) to relieve symptoms like difficulty urinating and for pulmonary arterial hypertension (PAH) to improve exercise capacity.

How Tadalafil Works for ED

Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor. It enhances blood flow to the penis by blocking the PDE5 enzyme, which regulates blood flow, facilitating an erection during sexual stimulation. For BPH, it relaxes bladder and prostate muscles, and for PAH, it widens blood vessels in the lungs.

Recommended Tadalafil Dosage

Dosage varies by condition:

• For ED (as needed): Starting dose is 10 mg, taken 30 minutes before sexual activity. May adjust to 5 mg or 20 mg based on response. Maximum one dose per day.
• For daily ED use: 2.5 mg to 5 mg once daily, taken at the same time each day.
• For BPH or ED/BPH: 5 mg once daily.
• For PAH: 40 mg (two 20 mg tablets) once daily.
• Older adults or kidney/liver issues: Lower doses may be recommended.

Follow your doctor’s instructions carefully.

Managing Common Tadalafil Side Effects

• Headache: Drink plenty of water or use over-the-counter pain relievers like acetaminophen (consult your doctor).
• Back pain/muscle aches: Apply heat or take a warm bath; pain may subside after a few days.

Tadalafil Interactions to Be Aware Of

Drug Interactions

Tadalafil may interact with:

• Nitrates: (e.g., nitroglycerin) – can cause severe low blood pressure.
• Alpha-blockers: (e.g., doxazosin) – may lead to hypotension.
• CYP3A4 inhibitors: (e.g., ketoconazole, ritonavir) – increase Tadalafil levels, requiring dose adjustments.
• CYP3A4 inducers: (e.g., rifampin) – may reduce Tadalafil’s effectiveness.

Disease Interactions

Use cautiously with:

• Heart disease or recent heart attack/stroke
• Severe liver or kidney disease
• Uncontrolled high or low blood pressure
• Penile deformities (e.g., Peyronie’s disease)

Food Interactions

Tadalafil can be taken with or without food. Unlike some ED medications, high-fat meals do not significantly delay its effect. However, avoid excessive alcohol, as it may increase side effects like dizziness or reduce erection effectiveness.
