Cheap Tadalafil Online: Generic Tadalafil 5 mg, 10 mg and 20 mg Prices
Why generic tadalafil costs less, how the 5 mg, 10 mg and 20 mg strengths are used, and sensible ways to keep monthly costs down safely.
- Quality generic medicines
- Prescription required
- Ships to the USA, UK, Canada & Europe
Cheap tadalafil is usually just generic tadalafil: the same active ingredient used in Cialis, made by other companies once the brand patent ended. It treats erectile dysfunction (ED) in the same way, at the same strength. This guide looks at the 5 mg, 10 mg and 20 mg strengths, how each one is used, and the honest ways to keep your costs down over months of treatment.
Saving money is sensible. Cutting corners on safety is not. Everything below assumes you have seen a doctor, have a prescription and are using the dose they set for you.
Key takeaways
- Generic tadalafil costs less because makers skip brand research and marketing costs, not because the medicine is weaker.
- Strengths are 2.5 mg, 5 mg, 10 mg and 20 mg. 2.5 mg and 5 mg are daily doses; 10 mg and 20 mg are usually on-demand.
- Your real cost depends on how often you take it, so work out your monthly use, not just the price per tablet.
- Larger packs and reordering early help you save and avoid gaps.
- Never take tadalafil with nitrates, “poppers” or riociguat.
- A valid prescription is required for every order of a prescription medicine.
What is cheap tadalafil?
Tadalafil is a PDE5 inhibitor. It helps blood flow into the penis when you are sexually aroused, so you can get and keep an erection. When people look for cheap Cialis online, what they find are generics such as Tadacip, Tadaboom and Ciasel. Each is tadalafil under a different trade name.
A generic must contain the same active ingredient at the stated strength. Inactive ingredients, colour and shape can differ. So a low price on its own is not a warning sign, as long as it comes from a store that asks for your prescription and lists the active ingredient and strength clearly. For the brand comparison, see our generic Cialis guide.
Tadalafil 5 mg, 10 mg and 20 mg: how each is used
Tadalafil 5 mg (and 2.5 mg)
5 mg is the usual daily dose. You take one tablet at the same time every day, so there is a steady level in your body and you do not have to plan around sex. Some men are started on 2.5 mg daily. The 5 mg daily dose is also used for urinary symptoms of an enlarged prostate.
Tadalafil 10 mg
10 mg is the usual starting dose for on-demand use. You take it at least 30 minutes before sex, and the effect can last up to 36 hours. Many men find 10 mg is enough.
Tadalafil 20 mg
20 mg is the highest standard dose. Doctors may raise the dose to 20 mg if 10 mg does not work well enough and side effects are mild. It is still taken no more than once a day. Tadalafil 20mg is one of the most searched strengths, including by readers in the UK and Canada, but it is not automatically the right one for you. Use it only if it is the strength on your prescription.
Food has little effect on tadalafil, so timing around meals matters less than with sildenafil. Read more about dosing in our guide to buying tadalafil online.
Safety comes before savings
Do not take tadalafil if you:
- Use nitrate medicines for chest pain (such as GTN spray or isosorbide) or “poppers”.
- Take riociguat.
- Have had a heart attack in the last 90 days, a recent stroke, or severe heart disease.
- Have very low blood pressure or uncontrolled high blood pressure.
- Have had sudden vision loss from reduced blood flow to the optic nerve.
Tell your doctor about alpha-blockers, blood pressure medicines, some HIV medicines, some antifungals and antibiotics, and kidney or liver problems. These may mean a lower dose, or a different medicine.
Side effects and when to get help
Common side effects are headache, indigestion, back or muscle pain, flushing and a stuffy nose. They usually settle. Get urgent help for chest pain, an erection lasting more than 4 hours, sudden loss of sight or hearing, or a severe allergic reaction.
Cheap tadalafil: why generic costs less
The company that first develops a medicine spends years on research and trials, then on marketing. Those costs are built into the brand price. Generic makers produce a medicine that is already proven, so they do not carry that load, and competition between several makers keeps prices fair.
That is the honest reason cheap tadalafil exists. It is not a different or diluted medicine. If a product page does not name the active ingredient or strength, or a seller does not ask for a prescription, look elsewhere.
What affects the price of cheap tadalafil online?
We do not quote prices here, because they change with stock, strength and pack. Instead, use this table to understand what moves your total.
| Factor | How it changes the price | What to check |
|---|---|---|
| How often you take it | Daily use needs a tablet every day; on-demand use may need only a few a month. | Your doctor’s plan, and your real monthly use. |
| Strength | Higher strengths can cost a little more per tablet. | The mg matches your prescription. |
| Pack size | Bigger packs usually lower the cost per tablet. | That the quantity matches your prescription and your dose is settled. |
| Trade name | Different makers price the same ingredient differently. | The page says “tadalafil” and the right strength. |
| Delivery | Shipping costs are spread over the whole order. | Delivery time and tracking to your country. |
Simple ways to save
- Think per month, not per tablet. A daily 5 mg plan and an occasional 20 mg plan can cost very different amounts over a month. Ask your doctor which plan suits your life, then budget for it.
- Choose a sensible pack size. Once your dose is settled, a larger pack usually costs less per tablet. If your dose may still change, start smaller.
- Reorder early. One order with enough tablets avoids paying for rushed or repeated shipping, and it stops gaps in daily treatment.
- Stick to the prescribed dose. Taking more than prescribed does not work better. It just uses tablets faster and raises side effects.
- Do not split tablets on your own. Only cut a tablet if your prescriber has said it is fine for that product.

Frequently asked questions
Is cheap tadalafil lower quality?
Not by itself. A generic is expected to contain the same active ingredient at the same strength. What matters is that the product names its ingredient and strength clearly and that you order it with a prescription.
Is tadalafil 20mg better value than 10 mg?
Only if 20 mg is the dose your doctor has prescribed. A higher strength than you need does not give better results, and it may cause more side effects.
Is daily 5 mg more expensive than on-demand?
Often, yes, because you take a tablet every day. Some men still prefer it for the freedom it gives, or because it also helps prostate symptoms. Weigh the benefits with your doctor.
Can I split a 20 mg tablet to make 10 mg?
Only if your prescriber has told you it is suitable for that specific product. Not all tablets split evenly, so the dose may not be accurate.
Is cheap Cialis online the same as generic tadalafil?
In most cases, yes. Genuine brand-name Cialis is rarely sold at a low price. Low-cost offers are generic tadalafil, and the product page should say so clearly.
Should I buy a big pack the first time?
It is usually better to start with a smaller pack until you and your doctor know the dose works for you. Once it is settled, a larger pack can lower the cost per tablet.
