Features of Senfuli
Senfuli is an ED treatment medication designed to improve symptoms of erectile dysfunction (ED).

This product contains the same active ingredient as the globally renowned ED treatment drug Viagra, characterized by large pale blue diamond-shaped tablets.

Efficacy of Senfuli
The active ingredient Sildenafil inhibits PDE-5 (phosphodiesterase type 5), an enzyme that impedes erectile function.

The PDE-5 enzyme breaks down cyclic guanosine monophosphate (cGMP), which is essential for erection.

When cGMP is broken down, erection becomes impossible, a condition known as ED (erectile dysfunction).

Sildenafil works by inhibiting the PDE-5 enzyme, dilating blood vessels around the penis and relaxing smooth muscles in penile cavernous tissue.

The resulting vasodilation and muscle relaxation effects facilitate increased blood flow into penile cavernous tissue, thereby inducing erection.

Duration of Senfuli's Effects
Effects last for 4 to 6 hours. Note that medication alone does not trigger automatic erection; sexual stimulation or arousal is required to initiate erectile response.

Specifications of Senfuli
Available in 50mg/100mg strengths through personal import channels on this website.

First-time users are advised to use a pill splitter to divide tablets, starting with half-dose administration.

Additional Information
This product maintains equivalent efficacy to Viagra while offering superior cost-effectiveness, significantly reducing medication expenses.

Dosage Timing
The correct way to take Sildenafil is on an empty stomach, one hour before sexual activity.

After the first dose, if another dose is needed, wait at least 24 hours before taking it again.

Dosage Reference
The Sildenafil sold on this site comes in 50mg and 100mg dosages. You can use a pill cutter to split the 50mg or 100mg tablets into halves for administration.

If the 25mg dose is not effective, you can gradually increase to 50mg or 100mg. Adjust to the appropriate dose based on your individual condition.

Some users take 2-3 times the prescribed dose at once to seek stronger effects, but this will not enhance the efficacy.

The maximum dose for a single sexual activity is 100mg.

For individuals with a small build, 25mg or 50mg may be sufficient.

Sildenafil with 100mg of active ingredient is more suitable for tall foreign men.

Recommended Dosage
When taking sildenafil-based medication for the first time, it is recommended to start with a 25mg dose.

Dietary Effects
It is recommended to fast for 2 hours before taking it.

This is related to the absorption process of sildenafil, the main ingredient.

Sildenafil needs to be absorbed through the intestines into the bloodstream.

Food in the stomach can cause the tablet to be absorbed prematurely, delaying its arrival in the intestines.

If a high-fat meal is consumed before taking it, the fat can coat the intestinal wall, reducing the absorption rate of the ingredient.

Poor absorption may cause the medication to fail or be insufficient, so it is essential to take it on an empty stomach.

The ingredient is absorbed within 30 minutes after administration, after which eating is unrestricted.

Alcohol Effects
Although it can be taken with alcohol, note that the vasodilatory effect may accelerate intoxication, so avoid excessive drinking.

Contraindications
・Individuals with cardiovascular disease (heart or vascular disorders) who are not suitable for sexual activity

・Individuals with severe liver dysfunction

・Patients with hypotension or uncontrolled hypertension without treatment

・Individuals with a history of cerebral infarction, cerebral hemorrhage, or myocardial infarction within the past 6 months

※Please follow your doctor's advice when taking it.

Common Side Effects
Common side effects include: decreased blood pressure due to vasodilation, eye congestion, facial flushing, palpitations, nasal congestion, etc.

These symptoms are attributed to the vasodilatory effects and may subside as sexual arousal increases and penile blood flow intensifies.

Special Symptoms
Special symptoms involving visual abnormalities may occur, such as experiencing blue-tinted vision as if wearing blue-tinted glasses, or difficulty distinguishing blue-green hues.

These are usually temporary and not a cause for concern. However, if significant vision loss occurs, there is a risk of non-arteritic anterior ischemic optic neuropathy (NAION).

If symptoms like sudden vision deterioration or blindness occur, consult an ophthalmologist immediately.

Additionally, an erection lasting more than 4 hours and accompanied by pain may indicate a risk of priapism (persistent erection).

If an erection persists beyond 4 hours, seek immediate medical treatment.

※What is Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION)?
This condition involves dysfunction or necrosis of optic nerve cells due to interrupted blood supply to the optic nerve.
This state is called ischemic optic neuropathy.
Although a direct causal relationship is not fully established, it is believed to be associated with the use of ED treatment medications.

※What is Priapism (Persistent Erection)?
Priapism, also known as persistent erection, is a condition where the penis remains erect and cannot return to a flaccid state or has difficulty doing so.
It is also termed penile rigidity.
The primary cause is believed to be dysfunction of the intracavernosal arterial system.
If an erection does not subside naturally and lasts more than 4 hours, seek medical attention immediately.

Contraindications
Contraindicated drugs are those that interact with Cenforce and should not be taken simultaneously.

・Nitrates and NO donor drugs
(Nitroglycerin, Amyl nitrite, Isosorbide dinitrate)
Concomitant use may enhance the blood pressure-lowering effect.

・Amiodarone hydrochloride
(Ancarone tablets)
Combined use may enhance the QTc interval prolonging effect caused by amiodarone hydrochloride.

Drug Interaction Precautions
Drugs requiring special precautions when taken with Cenforce are those that need careful attention due to potential interactions.

・Grapefruit (including juice)
Because its furanocoumarin components inhibit the activity of metabolic enzymes in the body, leading to delayed drug breakdown.
This may result in excessive absorption of the drug components, thereby enhancing the drug effect or worsening side effects.

・CYP3A4 inhibitors/inducers
Ritonavir, Saquinavir, Darunavir

・Antihypertensive drugs
Since Cenforce itself has a blood pressure-lowering effect, concomitant use with antihypertensive drugs may cause temporary symptoms such as dizziness, instability, and other signs of hypotension.

・Store in a cool place away from direct sunlight and low humidity.

・Keep out of reach of children.

・Do not change containers to avoid accidental ingestion or changes in quality.

・If you need to take the remaining medicine after dividing it, store it sealed to avoid contact with air and consume it within two days.

・Do not take or use products that have passed the expiration date.
