What is Tadalafil? (Cialis & Adcirca)
Tadalafil is a prescription medication widely used for treating erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH). Known commonly by its brand names Cialis (for ED/BPH) and Adcirca (for PAH), this drug is a member of the phosphodiesterase type 5 inhibitors (PDE5 inhibitors) family, a class proven to enhance vascular health and sexual function. Unlike other ED medications, Tadalafil is famous for its long-lasting effect—up to 36 hours!
Drug Name | Main Use | Onset of Action | Duration |
---|---|---|---|
Tadalafil (Cialis) | Erectile Dysfunction, BPH | 30-60 min | Up to 36 hours |
Sildenafil (Viagra) | Erectile Dysfunction | 30-60 min | 4-6 hours |
Adcirca (Tadalafil) | Pulmonary Arterial Hypertension (PAH) | 2 hours | 24-36 hours |
Want to experience the real-world impact of Tadalafil? Patients consistently report a marked improvement in sexual satisfaction and daily comfort. “Tadalafil’s longer window of action gives my patients real flexibility and confidence,” says Dr. Sara Emil, PharmD, emphasizing its unique advantage over similar drugs.
How Tadalafil Works: The Science Behind the Pill
Tadalafil works by inhibiting the phosphodiesterase type 5 (PDE5) enzyme. This increases the amount of cyclic guanosine monophosphate (cGMP)—a molecule that relaxes smooth muscles and dilates blood vessels. In erectile dysfunction, this process allows more blood to flow into the penis during arousal, resulting in a firm, sustained erection. For BPH, it relaxes muscles in the bladder and prostate, making urination easier. In PAH, it eases blood flow through the lungs, reducing blood pressure in pulmonary arteries.
- Increases blood flow to the penis (ED)
- Relaxes prostate/bladder muscles (BPH)
- Lowers pulmonary artery pressure (PAH)
Numerous clinical studies support Tadalafil’s efficacy and safety (Source: NIH review).
Tadalafil Dosage & Recommendations: How to Use Safely
Tadalafil comes in various strengths—2.5mg, 5mg, 10mg, and 20mg tablets. Your dosage depends on the condition being treated:
- Erectile Dysfunction (as needed): Start with 10mg, taken at least 30 minutes before activity. Dose may be increased to 20mg or decreased to 5mg based on effectiveness and tolerability. Do not take more than once per day.
- Erectile Dysfunction (daily use): 2.5mg to 5mg once daily, taken at the same time each day, regardless of sexual activity.
- Benign Prostatic Hyperplasia (BPH): 5mg once daily, preferably at the same time.
- Pulmonary Arterial Hypertension: Typically 40mg once daily, divided into two 20mg doses. Only use as directed by a doctor!
Indications for Tadalafil: When and Why You Might Need It
- Erectile Dysfunction
- Difficulty achieving or maintaining an erection adequate for sexual performance. Tadalafil’s extended window means less pressure to ‘schedule’ intimacy.
- Benign Prostatic Hyperplasia
- Common in older men, characterized by difficulty urinating. Tadalafil reduces bladder and prostate tension for relief.
- Pulmonary Arterial Hypertension
- A rare but serious condition affecting lung blood pressure. Tadalafil helps open blood vessels, lower pressure, and improve exercise ability.
Who Should NOT Take Tadalafil?
Tadalafil is not suitable for everyone. Do NOT use if you:
- Take nitrate medications (for chest pain/heart issues)—risk of dangerous blood pressure drops
- Have recent stroke or heart attack
- Have severe liver or kidney disease
- Are allergic to tadalafil or similar drugs
Always consult your healthcare provider before starting any new medication, especially if you have underlying health conditions.
Common Side Effects & Safety Profile
Tadalafil is generally well tolerated, but as with all medications, side effects can occur. Most are mild and disappear as your body adjusts:
- Headache
- Indigestion
- Back pain
- Muscle aches
- Flushing (redness, warmth)
- Stuffy or runny nose
Rare but serious side effects include sudden vision or hearing loss, chest pain, or an erection lasting more than 4 hours (priapism). These require immediate medical attention.
“Side effects are uncommon and typically short-lived,” notes Dr. Vincent Uhl, MD. “Most men tolerate Tadalafil extremely well, especially with careful dose selection.”
Interaction Alerts: Drugs and Foods to Avoid
- Nitrates (e.g. nitroglycerin): Severe blood pressure drop—dangerous!
- Alpha-blockers: For high blood pressure or prostate—can increase risk of low blood pressure.
- Some antifungals and antibiotics: May raise Tadalafil levels in your blood.
- Grapefruit and grapefruit juice: May increase side effects—avoid if possible.
Always provide your healthcare provider with a complete list of medications and supplements you use to prevent harmful interactions.
