What is Cialis? Understanding Tadalafil’s Role in Men’s Health
Cialis is the brand name for Tadalafil, a prescription medication mainly used to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH).
| Brand Name | Generic Name | Uses | Duration of Action | Typical Dosage |
|---|---|---|---|---|
| Cialis | Tadalafil | ED, BPH, PAH* | Up to 36 hours | 2.5 mg – 20 mg |
*PAH = Pulmonary arterial hypertension (under the brand Adcirca)
How Does Cialis Work? The Pharmacology Explained
Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor. Here’s what happens when you take Cialis:
- After sexual stimulation, nitric oxide is released in the penis.
- This increases levels of cyclic guanosine monophosphate (cGMP), which relaxes smooth muscle and increases blood flow.
- PDE5 breaks down cGMP. By inhibiting PDE5, Cialis prolongs the action of cGMP, enabling a strong, lasting erection.
Key takeaway: Cialis only works with sexual stimulation — it doesn’t cause an erection without arousal.

Cialis vs. Viagra: What Sets It Apart?
| Medication | Onset | Duration | Food Restrictions |
|---|---|---|---|
| Cialis | 30-60 minutes | Up to 36 hours (“The Weekend Pill”) | No significant effect |
| Viagra (Sildenafil) | 30-60 minutes | 4-6 hours | Fatty meals slow absorption |
Men often choose Cialis for its longer window of efficacy, allowing greater spontaneity and less pressure to “time” intimacy. This is a major psychological benefit as well as a practical one.
Indications: When is Cialis Prescribed?
- Erectile Dysfunction (ED): The most common indication. Cialis improves the ability to achieve and keep an erection sufficient for satisfactory sexual performance.
- Benign Prostatic Hyperplasia (BPH): For men with enlarged prostate, Tadalafil relieves urinary difficulties like frequent or urgent need to urinate.
- Pulmonary Arterial Hypertension: Under the Adcirca brand, used to treat high blood pressure in the lungs.
Off-label uses and ongoing studies explore further benefits, but always follow your healthcare provider’s guidance.
How to Use Cialis: Dosage & Administration
Always follow your doctor’s advice. However, general dosage guidelines are as follows:
| Purpose | Typical Starting Dose | How to Take |
|---|---|---|
| ED — as needed | 10 mg (may adjust to 20 mg or down to 5 mg) | At least 30 minutes before sex, not more than once daily |
| ED — daily use | 2.5 mg (can increase to 5 mg) | Once daily, regardless of sexual activity |
| BPH (with or without ED) | 5 mg | Once daily, at the same time each day |
- Do not take with other PDE5 inhibitors (like Viagra or Levitra).
- Alcohol in excess can increase risk of side effects.
- Avoid grapefruit juice (may affect metabolism).
How Long Does Cialis Last?
The effects of a single dose may last up to 36 hours, earning it the reputation as the “weekend pill.” This does not mean you will have a prolonged erection (priapism, a dangerous condition), but rather that the ability to get an erection is improved during this time.
Side Effects and Safety: What You Need to Know
While Cialis is widely used and generally well-tolerated, it’s important to be aware of possible side effects. Most are mild and short-lived, but some can be serious.
- Headache
- Flushing
- Indigestion
- Back pain
- Muscle aches
- Nasal congestion
- Dizziness
- Chest pain or irregular heartbeat
- Sudden loss of vision or hearing
- Priapism (erection lasting more than 4 hours)
- Allergic reactions: rash, swelling, shortness of breath
Never mix Cialis with nitrates (found in some heart medications) or guanylate cyclase stimulators. This can cause a dangerous drop in blood pressure. Always inform your healthcare provider of any medicine you take — including supplements and herbal products.
