Cialis Effects

The active ingredient in Cialis, "Tadalafil," promotes and maintains erections.
According to pharmaceutical company data, when taking Cialis (for ED patients), the successful penetration rate is 81.1% for 10mg and 82.1% for 20mg, demonstrating high ED improvement efficacy.

Cialis's effects can last up to 36 hours, exceeding one day, allowing for relaxed usage.

※Even if Tadalafil's effects persist, no erection will occur without sexual stimulation.
※Effect onset time varies by individual. (Approximately 1～4 hours after ingestion)

Beware of Counterfeit Cialis

When purchasing Cialis via cross-border e-commerce, some users may have concerns about overseas online shopping. However, with reputable platforms like ours, which have years of operational experience and a repeat purchase rate exceeding 78%, you can shop with complete confidence. All medications are sourced directly from pharmacies in their countries of origin, ensuring authenticity and medication safety.

Due to Cialis's global popularity, some fraudulent websites take advantage to sell counterfeit drugs.

One common counterfeit is ultra-high-dose Cialis. Genuine Cialis only comes in 5mg, 10mg, and 20mg dosages, while 50mg and 100mg versions are fakes.

To avoid purchasing counterfeit drugs, please verify carefully before buying.

Tadalafil product list:
・Cialis Generic Drugs

Cialis should be taken 1 hour before sexual activity with warm water.

The recommended starting dose is 10mg, with a maximum single dose of 20mg.
First-time users should start with 10mg and may increase to 20mg if insufficient effects are observed.
※Using a pill cutter to divide the tablet allows for 10mg half-dose administration.

Allow at least 24 hours between doses.

Duration After Single Dose

Cialis 20mg can maintain efficacy for up to 36 hours.
Therefore, the frequency of sexual activity is unrestricted during this effective period.

Note that this medication only enhances erectile function and does not boost energy or increase libido.

Re-dosing is permitted after 24 hours; daily intake can sustain the effect.

Food Interactions

Cialis is minimally affected by food intake.
Though it's advised to take on an empty stomach 2 hours before dosing, it can be taken with or without meals.
※High-fat meals may reduce drug absorption efficiency.

Cases of Ineffectiveness

If no effects are observed after administration, possible reasons include:

・Lack of sexual stimulation or arousal
The medication alone cannot induce erection; normal sexual stimulation is required.

・High-calorie meal consumption
While the impact is minor, it is not completely negligible.

・Insufficient time after dosing
Compared to other ED medications, Cialis has a longer onset time.
Individual variations exist—some may require 2-4 hours for full effect.
Early administration is recommended to avoid timing anxiety.

・Drug incompatibility
ED treatment varies individually; some may be insensitive to tadalafil.
If the brand-name version is ineffective, generics typically show the same result.
Alternative ED medications like Viagra or Levitra may be considered.

Contraindications

・Cardiovascular disease patients (those unfit for sexual activity)

・Patients with severe hepatic impairment

・Hypotensive patients or uncontrolled hypertensive patients

・History of stroke/myocardial infarction within the past 6 months

・Patients allergic to tadalafil

Specific Side Effects

·Visual abnormalities
Symptoms may include vision abnormalities resembling wearing blue-tinted glasses or difficulty distinguishing between blue and green colors.

·Non-arteritic anterior ischemic optic neuropathy (NAION)
Manifested as significant vision decline or loss.

This condition is a pathological state caused by insufficient blood supply to the optic nerve, leading to dysfunction or necrosis of optic nerve cells. Although the causal relationship remains unclear, studies suggest a weak correlation with the use of ED treatment medications.

·Persistent erection (Priapism)
May present as a painful erection lasting more than 4 hours that does not subside on its own.

This condition, also known as penile rigidity, is primarily caused by dysfunction in the arterial system within the corpus cavernosum of the penis.

If any of the above symptoms occur, seek immediate medical attention.

Precautions for Combined Medication

Caution-required drugs refer to medications that require special attention when used with Cialis.

· Grapefruit (including juice)
The furanocoumarin content may inhibit metabolic enzyme activity, delaying drug breakdown.
May result in excessive drug absorption, leading to heightened effects or aggravated side effects.

· CYP3A4 inhibitors/inducers
Ritonavir, saquinavir, darunavir

· Antihypertensive drugs
As Cialis itself has blood pressure-lowering effects, concurrent use with antihypertensives may cause temporary dizziness or other hypotension symptoms.

・Store in a cool, dry place away from direct sunlight.

・Keep out of reach of children.

・Do not transfer to another container to prevent accidental ingestion or product deterioration.

・For any remaining medication after dividing doses, store with minimal air exposure and consume within two days.
