Cenforce 100 mg Tablets (Sildenafil Citrate)

What Is Cenforce 100?

Cenforce 100 is a prescription medication containing sildenafil citrate, the same active ingredient found in Viagra. It is manufactured by Centurion Laboratories and is used as a treatment for erectile dysfunction (ED) in adult men. This standard-strength sildenafil formulation comes in tablet form and provides an effective, affordable alternative to brand-name ED medications. Each tablet contains 100 mg of sildenafil citrate, which is the most commonly prescribed dosage for men experiencing moderate erectile dysfunction.

What Is Cenforce 100mg Used For?

Cenforce 100 mg is used to treat erectile dysfunction by improving erectile response during sexual stimulation. It works by enhancing blood flow to the penis, which helps improve erection quality during intimacy. It does not treat libido, premature ejaculation, or sexual arousal disorders. The drug is intended for use only in adult men diagnosed with ED.

How Does Cenforce 100 Mg Work?

Cenforce 100 mg improves erectile function by sustaining cGMP levels and enhancing penile blood flow during arousal. Sildenafil citrate, the active ingredient in Cenforce, is a PDE5 inhibitor that blocks the enzyme phosphodiesterase type 5, which degrades cyclic guanosine monophosphate (cGMP) in penile tissue. By preventing cGMP breakdown, the medication enables this molecule to remain active longer, promoting prolonged smooth muscle relaxation and stronger erections.

Sexual stimulation triggers a nitric oxide–cGMP sequence that sildenafil magnifies.
During arousal, nitric oxide is released in the penis, which activates guanylate cyclase, an enzyme that boosts cGMP production. Accumulated cGMP relaxes vascular smooth muscle, allowing increased blood flow into the corpus cavernosum. Sildenafil 150 mg prolongs this process by maintaining elevated cGMP concentrations.

Erections depend on arousal, and sildenafil does not induce erections automatically.
The medication amplifies natural responses but does not initiate them. Sexual stimulation remains essential for nitric oxide release, which is the first step in the drug’s effect chain.

How Long Does Cenforce 100 Last?

Cenforce 100 typically begins to take effect within 30 minutes after ingestion, though individual response times may vary based on factors such as metabolism, food consumption, age, and overall health. The medication remains active in the body for approximately four to six hours, providing an extended window of opportunity for sexual activity.

The period of peak effectiveness, known as the half-life, occurs approximately 2-3 hours after taking the medication. During this time, the 150 mg dosage provides its most potent effects, with gradually diminishing efficacy over the subsequent hours. After the active period, the medication is metabolized and eliminated from the body through normal kidney and liver processes without accumulating in the system when used as directed.

What Is The Dosage Of Cenforce 100?

The recommended dosage of Cenforce 100 is one tablet before 30 minutes of sexual activity per 24-hour period. Exceeding this dosage increases the risk of severe side effects without enhancing efficacy. Adjustments to dosage should only be made under medical supervision.

Can I Take Cenforce 100 With Alcohol?

Alcohol can reduce Cenforce 100’s effectiveness and increase side effects like dizziness.  Both alcohol and sildenafil lower blood pressure, and when combined, can cause lightheadedness, headaches, delayed drug effect, and impaired judgment during sexual activity. Small amounts (1 drink or less) may have minimal impact, but heavy drinking should be avoided.

Is Cenforce 100 The Same As Viagra?

Cenforce 100 and Viagra are similar in their primary function because both contain 100 mg of sildenafil citrate, the active ingredient that treats erectile dysfunction by increasing blood flow to the penis. However, there are key differences between the two. Viagra is the original branded medication developed by Pfizer and is regulated under strict FDA standards in the United States. Cenforce 100, on the other hand, is a generic version manufactured by Centurion Laboratories in India. Although their effects are pharmacologically equivalent for most users, the formulations may differ slightly due to inactive ingredients. Cenforce is generally much more affordable than Viagra, making it a popular choice in markets where brand-name drugs are either unavailable or too expensive.

What Is The Price Of Cenforce 100 Mg?

The cost of Cenforce 100mg can vary, based on the seller, how much you buy, and where you are located. Typically, Cenforce 100 mg is less expensive than branded products like Viagra.

Where Can I Buy Cenforce 100?

Cenforce 100 mg can be found on various online websites, but care should be exercised. Being a generic form of Viagra, it is generally sold outside of the regulatory controls, and thus chances are higher of it being a counterfeit or low-quality product. The U.S. FDA and other health agencies have cautioned against buying erectile dysfunction drugs from unapproved internet sellers because of possible health risks. To maintain efficacy and safety, consumers can access Cenforce 100 mg only from licensed pharmacies or telehealth providers with valid prescriptions.

Is Cenforce 100 Safe?

Cenforce 100 is considered safe for most healthy men when used as prescribed by a healthcare professional, but it is not suitable for everyone. Men with certain medical conditions, such as severe heart disease, significant liver or kidney impairment, or anatomical abnormalities of the penis, should avoid taking sildenafil citrate unless advised otherwise by a doctor. Safety also depends on avoiding drug interactions. Cenforce 100 should not be taken alongside nitrates, alpha-blockers, or other PDE5 inhibitors, as these combinations can cause dangerous drops in blood pressure (hypotension). Alcohol, grapefruit juice, and certain antibiotics or antivirals can also interfere with how the medication is absorbed or metabolized.
