Tadacip Features

Tadacip is a generic version of Cialis produced by Indian pharmaceutical company Cipla.

Differences from Brand-Name Cialis

As a generic version of Cialis, Tadacip contains the same 20mg of tadalafil as the original drug.

It offers equivalent efficacy and safety, with identical administration methods to Cialis.

However, Tadacip is priced more affordably than Cialis.

Choosing Tadacip can significantly reduce ED treatment costs.

Timing of Administration

Tadacip should be taken on an empty stomach, 1 hour before sexual activity for optimal effectiveness.

After each dose, wait at least 24 hours before taking another.

Dosage Reference

The Tadacip sold on this website comes in 20mg tablets, but you may split a 20mg tablet in half using a pill cutter to take a 10mg dose.

If 10mg proves insufficient, you may increase the dose to 20mg. Adjust according to your individual needs.


The maximum recommended dose per sexual encounter is 20mg.

※ First-time users of medications containing tadalafil (Tadacip's active ingredient) are advised to start with 10mg.

Food Interactions

The active ingredient tadalafil is considered minimally affected by food intake.

However, some effects may still occur, so it's recommended to avoid eating for 2 hours before taking the medication.

Additionally, consuming high-fat meals before taking Tadacip may cause fats to coat intestinal walls, potentially leading to poor absorption.

Poor absorption may result in reduced effectiveness, so taking it on an empty stomach is ideal.

The medication typically takes about 30 minutes to be absorbed, after which you may eat freely.

User Reviews Regarding Food and Tadacip

Below are customer reviews regarding food interactions.

Alcohol Interaction

While alcohol can be consumed with Tadacip, its vasodilating effects may accelerate intoxication, so excessive drinking should be avoided.

Who Should Not Take Tadacip

・Individuals with cardiovascular disease (heart or blood vessel conditions) for whom sexual activity is inadvisable

・Those with severe liver impairment

・Individuals with hypotension, or uncontrolled hypertension

・Those who have experienced stroke, cerebral hemorrhage, or myocardial infarction within the past 6 months

・Anyone allergic to tadalafil

※ Always follow your doctor's instructions when taking this medication.

Primary Side Effects

The main side effects include decreased blood pressure due to vasodilation, eye congestion, facial flushing, palpitations, and nasal congestion.
These symptoms are believed to be caused by vasodilation effects, and when sexual desire increases, the increased blood flow to the penis may alleviate the side effects.

Severe Symptoms

Special visual abnormalities may occur: such as a blue filter sensation, difficulty distinguishing blue-green colors, and other abnormal visual phenomena.
In most cases, these are transient and not a cause for concern. However, if significant vision loss occurs, be alert to the risk of non-arteritic anterior ischemic optic neuropathy (NAION).
If sudden vision loss or vision impairment occurs, consult an ophthalmologist immediately.
If painful erection persists for more than 4 hours, priapism (abnormal erection) may be present.
If erection lasts more than 4 hours without relief, seek medical attention immediately.

※What is Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION)?
It is a condition where blood supply to the optic nerve is interrupted, causing dysfunction or necrosis of optic nerve cells.
This state is known as ischemic optic neuropathy.
Although the causal relationship is not yet clear, studies have found a slight correlation with ED treatment medications.

※What is Priapism (Abnormal Erection)?
It refers to a condition where the penis remains erect and cannot subside or is difficult to subside.
Also known as penile rigidity.
The primary cause is dysfunction of the penile arterial system.
If erection persists for more than 4 hours without relief, seek professional medical treatment immediately.

Contraindications

Contraindicated medications refer to drugs that may interact with Tadacip and must not be taken concurrently.
