Frequently asked questions
What is Cialis?
Cialis is the brand name for tadalafil, a prescription medicine primarily used to treat erectile dysfunction (ED). It is also approved for symptoms of benign prostatic hyperplasia (BPH) and, in some cases, for both conditions together. Tadalafil belongs to a class of drugs called PDE‑5 inhibitors.
How does Cialis work in the body?
Cialis helps relax blood vessels and improve blood flow to specific tissues. For ED, this improved blood flow supports an erection in response to sexual stimulation. It does not cause an automatic erection without stimulation.
How is Cialis different from Viagra and similar drugs?
The main difference is duration: Cialis can work for up to 36 hours in some people, which is why it’s often called the “weekend pill.” Other PDE‑5 inhibitors usually have shorter windows of effect. Individual response varies.
What conditions can Cialis be used for?
Cialis is commonly used for erectile dysfunction and urinary symptoms associated with an enlarged prostate (BPH). In some patients, it may be prescribed when both conditions are present. It is not intended to boost libido.
Who should not take Cialis?
People who take nitrates for chest pain or certain blood pressure medications should not use Cialis due to the risk of dangerous drops in blood pressure. It may also be unsuitable for those with specific heart conditions. A doctor’s evaluation is essential.
What are the most common side effects?
Common side effects include headache, facial flushing, nasal congestion, indigestion, and back or muscle pain. These effects are usually mild to moderate and temporary. Not everyone experiences side effects.
Can Cialis be dangerous?
Serious complications are rare but possible, especially when combined with contraindicated medications. Sudden vision or hearing changes and prolonged erections require immediate medical attention. Proper medical supervision greatly reduces risks.
Does Cialis affect blood pressure?
Cialis can slightly lower blood pressure by relaxing blood vessels. For most healthy adults this is not a problem, but interactions with other medications can amplify the effect. This is why medication review is important.
How quickly does Cialis start working?
Many people notice effects within 30–60 minutes, though this can vary. Food has less impact on tadalafil compared to some alternatives. Planning ahead is still recommended.
Can Cialis be taken every day?
Some patients are prescribed a daily-use regimen under medical supervision. This approach is different from occasional use and requires careful assessment by a healthcare provider. Never decide this on your own.
Is Cialis safe for long-term use?
Clinical studies suggest that tadalafil can be safe for long-term use when monitored by a doctor. Regular follow-ups help ensure ongoing safety and effectiveness. Self-medication increases risk.
When should I see a doctor about erectile problems?
If ED persists for several weeks, worsens, or is accompanied by pain or other symptoms, medical evaluation is recommended. ED can be an early sign of cardiovascular or metabolic conditions. Early assessment can improve outcomes.
Detailed breakdown
Cialis and erectile dysfunction: what it really treats
Erectile dysfunction is often linked to blood flow, nerve signaling, hormones, or psychological factors. Cialis addresses the blood-flow component by inhibiting PDE‑5, an enzyme that restricts circulation. It does not cure the underlying cause but can improve function while other issues are addressed.
Use in benign prostatic hyperplasia (BPH)
BPH causes urinary symptoms such as weak stream or frequent urination. Tadalafil helps relax smooth muscle in the prostate and bladder, easing these symptoms. This dual benefit makes Cialis unique among ED medications.
Safety considerations and interactions
The most critical safety issue is interaction with nitrates and certain alpha‑blockers. Alcohol can also intensify side effects like dizziness. A full medication and health history helps prevent complications.
Effectiveness and expectations
Cialis improves the ability to achieve and maintain an erection but does not increase sexual desire. Response depends on health status, cause of ED, and adherence to medical advice. Realistic expectations improve satisfaction.
Psychological and lifestyle factors
Stress, anxiety, sleep quality, and physical activity all influence sexual health. Medication works best when combined with healthy lifestyle choices. For more context, see related materials in our Health Education section.
