Tadalis SX
Ajanta Pharma's tadalafil 20 mg tablet, the long-window alternative to Kamagra. One dose can keep working for up to 36 hours, so there is far less watching the clock.
Tadalis SX is the tadalafil tablet in Ajanta Pharma’s range, the same company behind Kamagra. Where Kamagra uses sildenafil, Tadalis SX uses tadalafil, the active ingredient in Cialis, at 20 mg. The reason people choose it is time. Licensed tadalafil can keep helping for up to 36 hours after one dose, which is why Cialis is often called the “weekend pill”. There is less need to plan around a single hour, and more room for things to happen naturally.
Tadalis SX at a glance

- What is inside: tadalafil 20 mg, the same active ingredient as Cialis.
- The format: a tablet swallowed with water.
- Preparation: A tablet swallowed with water, with dose and timing set by the prescriber.

The Tadalis SX format
The big difference from a sildenafil tablet is the relaxed timing. The Cialis label says tadalafil can be taken at least 30 minutes before sex, and in its studies men responded better than with placebo for up to 36 hours after a dose. Food makes no real difference to how tadalafil is absorbed, so there is no need to plan a light dinner around it.
Like every medicine in this family, tadalafil needs sexual arousal to work. It helps an erection happen when you are in the mood; it does not cause a lasting erection on its own. The most common side effects on the label are headache, indigestion, back pain and aching muscles, usually mild and short-lived.
Tadalis SX or Kamagra?
| Tadalis SX | Kamagra Tablets | |
|---|---|---|
| Active ingredient | Tadalafil 20 mg | Sildenafil 100 mg |
| When to take it | At least 30 minutes before sex | About an hour before sex |
| How long it can help | Up to 36 hours | A shorter window |
| Food | Makes little difference | A heavy meal can slow it down |
| Best for | People who want a relaxed, longer window | People who plan for a specific evening |
Some sellers describe tadalafil as “stronger” than sildenafil. The two work in the same way; the clear difference is how long tadalafil lasts. Sildenafil vs tadalafil vs vardenafil compares all three side by side.
Strength
Each tablet is 20 mg, the top on-demand dose in the Cialis label. Licensed tadalafil usually starts at 10 mg, moves to 20 mg if 10 mg is not enough, and is taken no more than once a day; lower 2.5 mg and 5 mg daily doses are a separate plan for men who expect frequent use. A pharmacist or doctor can help you find the right amount, especially if you take other medicines.

Tadalis SX questions
How do you take Tadalis SX?
A tablet swallowed with water, with dose and timing set by the prescriber. See the strength section above for the medicine context.
Does up to 36 hours mean a 36-hour erection?
No. It means tadalafil can help you get an erection when you are aroused at any point in that window. Without arousal, nothing happens.
Is Tadalis SX stronger than Kamagra?
Not stronger, just longer-lasting. Both belong to the same family of medicines; tadalafil simply stays active for much longer than sildenafil.
What are the common side effects?
Headache, indigestion, back pain and aching muscles are the most common, along with a flushed face and a blocked nose. They are usually mild and pass.
Is the picture a real pack?
No. It is an AI-generated illustration of the product, not a photo of a specific pack.
Tadalafil or sildenafil?
The main choice is the timing window, not the brand name. See the three medicines side by side and pick the one that suits your plans.
