01 / The basics

What is Cialis?

Cialis contains tadalafil, a PDE5 inhibitor used for erectile dysfunction in adult men. Certain daily regimens are also used for symptoms of benign prostate enlargement (BPH). For erectile dysfunction, sexual stimulation is necessary.

It helps preserve the cGMP signal involved in relaxing penile smooth muscle and increasing blood flow. It is not an aphrodisiac or a cure for every cause of erectile dysfunction.

Sources: EMA ↗ · MedlinePlus ↗

02 / Use & dosage

Two different treatment schedules.

The following is a summary of approved information, not a dose recommendation for you. A clinician selects the regimen according to diagnosis, response, other medicines and kidney or liver function.

As needed · ED
10 mg / 20 mg

EMA information describes 10 mg at least 30 minutes before sexual activity; a doctor may increase it to 20 mg. Maximum frequency is once a day. Continuous daily 10–20 mg use is not recommended.

Once daily
2.5 mg / 5 mg

For ED, EMA describes 5 mg daily, reducible to 2.5 mg for tolerability. For BPH, the described regimen is 5 mg daily. Daily treatment needs periodic reassessment.

Sources: EMA product information ↗

Swallow the tablet with water; it may be taken with or without food. Follow your prescription and the leaflet supplied with your pack. Do not take an extra tablet to compensate for a missed dose.

Sources: NHS ↗

03 / Expectations

What does “up to 36 hours” mean?

Trials have assessed erectile response 24 and 36 hours after dosing. This describes a possible response window with sexual stimulation, not a continuous erection or a guarantee that it works for everyone.

Sources: PubMed ↗

Individual response varies. Tadalafil does not prevent pregnancy or sexually transmitted infections. Persistent difficulties deserve medical evaluation rather than repeated self-adjustment of the dose.

Sources: MedlinePlus ↗

04 / Adverse effects

Know the possible side effects.

Not everyone experiences side effects. Commonly reported effects include:

Headache Indigestion Back pain Muscle pain Blocked nose Flushing

Ask a pharmacist or doctor about persistent or troublesome symptoms. This list is not exhaustive; read the full leaflet.

Sources: NHS ↗

When to get urgent medical help

An erection lasting 4 hours or longer, sudden loss of vision or hearing, chest pain, or a severe allergic reaction require urgent assessment. Stop use and seek medical help. In an emergency, call your local emergency number.

With chest pain, do not take nitrate medicines yourself. Tell emergency staff when you last took tadalafil.

Sources: Lilly ↗ · EMA product information ↗

05 / Before use

Interactions matter.

Do not combine tadalafil with nitrates or riociguat. This can cause a dangerous fall in blood pressure. Nitrate-containing “poppers” are also unsafe.

Alpha-blockers, blood pressure medicines, strong CYP3A4 inhibitors (such as ritonavir or ketoconazole), and heavy alcohol intake may alter safety. Do not combine it with other erectile dysfunction medicines without medical guidance.

Heart disease, recent heart attack or stroke, previous serious eye problems, and kidney or liver disease need a clinician’s review before treatment. If sexual activity is medically inadvisable, Cialis must not be used.

Sources: Lilly ↗ · EMA ↗

Look at the evidence

Research, with context.

Research supports population-level understanding. It does not replace an individual assessment or establish the right dose for you.

2003 · Randomized controlled trial

Erectile response at 24 and 36 hours

A placebo-controlled study examined tadalafil response at specified intervals after dosing. The finding concerns successful sexual activity attempts, not uninterrupted erections.

Read the PubMed record ↗
2006 · Randomized controlled trial

Once-daily dosing studied over 12 weeks

A 268-participant study compared once-daily tadalafil with placebo. Historical trial doses should not be treated as today’s prescribing recommendation; consult current product information.

Common questions

A little more clarity.

Start with the facts. Keep personal treatment decisions with your clinician.

Can I order Cialis from this site?

No. PriceCialis is exclusively an information site. There is no shop, order form, payment process, prescription service or seller referral.

Are these live prices?

No. These are dated source records for seven markets. A check date is not a new price-list date. Insurance, taxes, pack sizes and price ceilings differ; confirm your current local cost with a licensed pharmacist.

Is generic tadalafil the same brand as Cialis?

Cialis is a brand; tadalafil is the active ingredient. Generic tadalafil is not the Cialis brand. Compare the prescribed strength and presentation, and ask a pharmacist about substitution. EMA ↗

Should I choose a dose by its price?

No. The price table is for understanding costs. The dose and schedule depend on clinical assessment, not which pack appears cheaper.

Is this the official Cialis website?

No. This is an independent educational resource, unaffiliated with Lilly or a medicine regulator. We do not claim medical endorsement or specialist review.

Is the guide limited to one country?

No. All seven language versions address readers worldwide. Languages are not country or currency settings. Country-specific price records are labelled separately.
