“Tadalafil”: what it is and what your next step should be
Disclaimer: This article is for informational purposes only and does not replace professional medical advice, diagnosis, or treatment. Tadalafil is a prescription medication. Always consult a qualified healthcare professional before starting or changing any treatment.
Tadalafil (brand name Cialis® and generics) is a medication most commonly used for erectile dysfunction (ED), but it is also prescribed for benign prostatic hyperplasia (BPH) and, in specific formulations, pulmonary arterial hypertension (PAH). If you’re searching for “how tadalafil works,” “tadalafil side effects,” or “Cialis for ED,” you’re likely looking for clear next steps. This guide walks you from symptom to action.
3 typical scenarios
Scenario 1: Difficulty getting or maintaining an erection
What is experienced: You notice repeated difficulty achieving or sustaining an erection firm enough for satisfactory sexual activity. It may be occasional or ongoing.
What this might mean: Erectile dysfunction can be linked to stress, anxiety, relationship concerns, diabetes, cardiovascular disease, hormonal changes, medication side effects, or lifestyle factors (smoking, alcohol, inactivity). Occasional issues are common; persistent symptoms may indicate an underlying health condition.
What a doctor usually does:
- Asks about onset, frequency, and severity of symptoms
- Reviews medical history (heart disease, diabetes, hypertension)
- Checks current medications (especially nitrates)
- May order blood tests (glucose, lipids, testosterone)
- Assesses cardiovascular risk before prescribing PDE5 inhibitors like tadalafil

Scenario 2: Urinary symptoms due to enlarged prostate (BPH)
What is experienced: Frequent urination, weak stream, difficulty starting urination, or waking at night to urinate.
What this might mean: These symptoms may be associated with benign prostatic hyperplasia (BPH), a common condition in aging men. Tadalafil is sometimes prescribed to help relieve lower urinary tract symptoms.
What a doctor usually does:
- Evaluates urinary symptom score and duration
- Performs a physical exam (possibly including digital rectal exam)
- Orders urine tests and sometimes PSA testing
- Assesses whether tadalafil alone or in combination with other BPH medications is appropriate

Scenario 3: You’re considering tadalafil after seeing online ads
What is experienced: You’ve seen advertisements for Cialis or generic tadalafil promising long-lasting effects (up to 36 hours) and are wondering if it’s safe for you.
What this might mean: Tadalafil is effective for many people, but it is not suitable for everyone. Certain heart conditions, low blood pressure, recent stroke or heart attack, or use of nitrate medications can make it unsafe.
What a doctor usually does:
- Reviews cardiovascular health
- Checks for contraindicated medications (e.g., nitrates, riociguat)
- Discusses realistic expectations and potential side effects
- Explains differences between on-demand and once-daily regimens (without deciding dosage outside prescription context)
If you are unsure about safety, start with a medication safety check and drug interaction guide.
Decision tree: what to do next
- If erection problems happen rarely and during stress ? Then consider lifestyle adjustments and monitor; seek medical advice if it persists.
- If symptoms persist for more than a few weeks ? Then schedule a primary care or urology appointment.
- If you have diabetes, heart disease, or high blood pressure ? Then prioritize medical evaluation before using any ED medication.
- If you take nitrates for chest pain ? Then do not use tadalafil; discuss alternatives with your doctor.
- If urinary symptoms affect daily life ? Then request evaluation for BPH and discuss whether tadalafil is appropriate.
- If you experience side effects after starting tadalafil ? Then contact your healthcare provider for guidance.
When to seek help urgently (red flags)
- Chest pain during sexual activity: Could indicate heart problems; seek emergency care.
- Erection lasting more than 4 hours (priapism): Requires immediate medical attention to prevent permanent damage.
- Sudden vision loss or hearing loss: Rare but serious; stop medication and seek urgent evaluation.
- Severe dizziness or fainting: May signal dangerous blood pressure changes.
- Allergic reaction: Swelling of face, lips, or throat; difficulty breathing.
Approaches to treatment/management (overview)
Treatment depends on the underlying cause. Tadalafil is one option among several.
PDE5 inhibitors (e.g., tadalafil, sildenafil, vardenafil)
These medications improve blood flow to the penis during sexual stimulation. Tadalafil has a longer duration of action compared to some alternatives. Taken only as prescribed by a doctor.
Lifestyle modifications
- Weight management
- Regular physical activity
- Smoking cessation
- Limiting alcohol intake
- Managing stress and sleep
Psychological counseling
If anxiety, depression, or relationship issues contribute to ED, therapy may be helpful alongside or instead of medication.
Hormonal evaluation
If low testosterone is suspected, a doctor may order blood tests and discuss appropriate management.
Devices or other therapies
Vacuum erection devices, injectable therapies, or surgical options may be considered in specific cases when oral medications are ineffective or contraindicated.

Prevention and long-term health
Because erectile dysfunction and BPH are often linked to overall vascular and metabolic health, prevention overlaps with heart-healthy habits.
- Control blood pressure, cholesterol, and blood sugar
- Exercise most days of the week
- Eat a balanced diet (Mediterranean-style patterns are often recommended)
- Maintain open communication with your partner
- Have regular medical check-ups after age 40–50

Bottom line: Tadalafil can be an effective and well-tolerated treatment for erectile dysfunction and certain urinary symptoms, but it’s not a one-size-fits-all solution. If you’re experiencing symptoms, your next best step is a medical evaluation to clarify the cause and choose the safest, most effective option.
