Daily Tadalafil: Tadalafil 5mg Daily — Complete UK Guide
How it works, who it suits, the build-up period, the BPH dual licence, side effects and daily vs on-demand.
When to get urgent help: Call 999 if you get chest pain during or after sex (tell the paramedics you have taken tadalafil, as nitrates such as GTN must not be given), or signs of a serious allergic reaction. Go to A&E straight away if an erection is painful or lasts more than 2 hours (do not drive yourself). Stop tadalafil and go to A&E straight away if you have a sudden decrease or loss of vision or hearing. See your GP about new erection problems or urinary symptoms, as they can be signs of other health conditions.

Key fact: Daily tadalafil 5mg keeps a steady level of the drug in your bloodstream, so PDE5 inhibition is continuous and there's no dosing window to think about. Once a steady level is reached (after about 5 days), erections become easier whenever you're sexually stimulated — no planning around a tablet required.

Start Consultation →Who Is Daily Tadalafil For?
Men who want complete spontaneity
On-demand ED medication always means planning ahead — taking a tablet before sex. Daily tadalafil takes that out of the equation. No timing, no planning, no dosing window.
Men who have sex 2+ times a week
The daily dose is intended for men who expect to have sex at least twice a week. A prescriber can advise whether daily or as-needed tablets suit your pattern better.
Men with BPH
Tadalafil 5mg daily holds a dual MHRA licence for both ED and lower urinary tract symptoms linked to benign prostatic hyperplasia (BPH) — the only ED medication with this dual indication. One tablet treats both.
Men who find on-demand timing stressful
Some men find having to anticipate sex and time a dose adds performance pressure. Continuous background coverage can feel psychologically easier.
How Daily Tadalafil Works Differently from On-Demand
On-demand tadalafil (10mg or 20mg) reaches its highest level in the blood about 2 hours after the dose and can keep working for up to 36 hours.
Daily tadalafil 5mg works differently. It builds to a steady-state plasma concentration after roughly 5 days of consecutive daily dosing. Once you're at steady state, the level of tadalafil in the bloodstream stays roughly constant, giving continuous PDE5 inhibition throughout the day.
Build-up period: Daily tadalafil takes about 5 days of daily doses to reach a steady level in your body. Don't judge how well it's working before you've completed at least a full week of daily dosing. Sexual stimulation is still required — it doesn't produce spontaneous erections.
Dosage and How to Take It
| Dose | Timing | With food? | Notes |
|---|---|---|---|
| 5mg (standard daily dose) | Same time each day, every day | Yes — unaffected by food | Standard dose for most men; licensed for both ED and BPH |
| 2.5mg (reduced dose) | Same time each day, every day | Yes | Used if 5mg causes side effects. Not shown to be effective for BPH. Daily dosing is not recommended if you have severe kidney problems |
- Take it at roughly the same time each day, regardless of planned sexual activity
- If you miss a dose, take it when you remember, but never take two doses on the same day
- Don't take on-demand tadalafil on the same day as a daily dose
- Don't combine it with other PDE5 inhibitors
Side Effects of Daily Tadalafil
- Headache and facial flushing — common, especially when you start; often become less noticeable over time
- Back pain and muscle aches — common; usually mild and short-lived
- Blocked nose — common
- Indigestion — common
- Dizziness or low blood pressure — tell your prescriber if you take blood pressure medicines or alpha-blockers, as tadalafil with doxazosin is not recommended
The absolute contraindication with nitrate medicines applies just as much to daily tadalafil. Because the drug is always present, the nitrate interaction is always present too, rather than time-limited. See our tadalafil guide for the complete list of who should not take tadalafil and the medicines it interacts with.
Get medical help straight away if you have an erection that is painful or lasts more than 2 hours (go to A&E straight away, and do not drive yourself), chest pain during or after sex (call 999 and tell them you have taken tadalafil), a sudden decrease or loss of vision or hearing (stop tadalafil and go to A&E straight away), or signs of a serious allergic reaction (call 999).
Daily vs On-Demand Tadalafil: Which Is Right for You?
| Daily 5mg | On-demand 10/20mg | |
|---|---|---|
| Timing of dose | Same time every day | At least 30 minutes before sexual activity |
| Spontaneity | Complete — no dosing window | Needs a little planning, but one dose can work for up to 36 hours |
| Best suited to | Sex ≥2x/week; spontaneity; BPH co-morbidity | Sex <2x/week; occasional use |
| Side effects | Most likely in the first few weeks; often settle with time | Time-limited; resolve with the dose |
If you have sex less than twice a week, on-demand tadalafil 10mg or 20mg may suit you better.
UK safety and prescribing information
- Legal status: daily tadalafil (2.5mg and 5mg) is a prescription-only medicine (POM) in the UK. Access Doctor supplies MHRA-licensed UK medicines, dispensed by our GPhC-registered pharmacy (#9011198) only after a prescriber has assessed your consultation. It is illegal to sell or supply prescription-only medicines without a prescription in the UK.
- Maximum dose: one tablet a day. Do not take as-needed tadalafil on the same day as a daily dose.
- Interactions: never take tadalafil with nitrates (including GTN spray), nicorandil, “poppers” or riociguat. Tell your prescriber about alpha-blockers, other blood pressure medicines, HIV medicines such as ritonavir, and antifungals or antibiotics such as ketoconazole or clarithromycin.
- Driving: tadalafil can cause dizziness. Check how it affects you before driving or using machinery.
- Review: your prescriber should review daily treatment regularly to check it is still right for you.
Frequently Asked Questions
What is daily tadalafil and how does it differ from on-demand?
Daily tadalafil (5mg, or sometimes 2.5mg, every day) keeps a steady level of the medicine in your body, so there is no need to time a tablet around sex. On-demand tadalafil (10mg or 20mg) is taken at least 30 minutes before sex and can work for up to 36 hours.
How long does it take for daily tadalafil to work?
It takes about 5 days of daily doses to reach a steady level in your body. Give it at least a week before judging how well it works.
Can I take daily tadalafil if I also have BPH?
Yes. Tadalafil 5mg once a day is licensed for both erectile dysfunction and the urinary symptoms of an enlarged prostate (BPH), and it is the only ED medicine licensed for both. One daily tablet can treat both conditions.
What if I miss a daily tadalafil dose?
Take it as soon as you remember, but never take two doses on the same day.
Who is daily tadalafil most suitable for?
Men who expect to have sex at least twice a week, want to be ready without planning, also have urinary symptoms of an enlarged prostate, or find timing a tablet stressful.
Does daily tadalafil cause side effects every day?
Side effects such as headache and flushing can happen when you start. For many men they become less noticeable over time. If they continue, your prescriber may lower the dose to 2.5mg or suggest as-needed tablets instead.
