Cenforce 100 mg Tablet (Sildenafil)

What is Cenforce 100 mg?

Cenforce 100 mg is an oral tablet used to treat erectile dysfunction (ED) in adult men. Each tablet contains 100 mg of Sildenafil Citrate, the same active ingredient found in Viagra. It belongs to a group of medicines called phosphodiesterase type 5 (PDE-5) inhibitors.

Cenforce is manufactured by Centurion Laboratories Pvt. Ltd. in India and is supplied in strips of 10 film-coated tablets. The 100 mg tablet is the highest dose of sildenafil approved for ED and is usually prescribed when a lower dose (25 mg or 50 mg) has not worked well enough.

Cenforce 100 mg is a prescription medicine. A doctor should check your heart health, blood pressure and current medicines before you start it.

What is Cenforce 100 mg used for?

Cenforce 100 mg is used to treat erectile dysfunction – the repeated inability to get or keep an erection firm enough for sexual activity.

• It helps men with ED get and maintain an erection when sexually aroused.
• It does not cure ED; it works only for the time the medicine is active in the body.
• It does not increase sexual desire and does not work without sexual stimulation.
• It does not protect against pregnancy or sexually transmitted infections, including HIV.

How does Cenforce 100 mg work?

During sexual arousal, the body releases nitric oxide, which raises a chemical called cGMP in the penis. cGMP relaxes the smooth muscles of the blood vessels so more blood can flow in and an erection forms.

An enzyme called PDE-5 breaks down cGMP. Sildenafil, the active ingredient in Cenforce 100 mg, blocks PDE-5. This keeps cGMP levels higher for longer, which improves blood flow to the penis and helps you get and keep an erection when you are sexually stimulated. Once arousal ends, the erection goes away normally.

How to take Cenforce 100 mg

Take Cenforce 100 mg exactly as your doctor has prescribed.

• Dose: One tablet, only when needed for sexual activity.
• Timing: About 1 hour before sexual activity. It can be taken anywhere from 30 minutes to 4 hours before.
• How: Swallow the tablet whole with a glass of water. Do not crush or chew it.
• Food: It can be taken with or without food. A heavy or high-fat meal can delay the effect, so a light meal works best.
• Maximum: Do not take more than one tablet in 24 hours.
• Alcohol: Avoid alcohol or keep it minimal; it can lower blood pressure and make erections harder to achieve.

If 100 mg causes side effects or feels too strong, ask your doctor about a lower strength. Do not increase the dose on your own.

How long does Cenforce 100 mg take to work and how long does it last?

Cenforce 100 mg usually starts working within 30 to 60 minutes of taking it. The effect lasts about 4 to 5 hours. During this time you can get an erection when sexually aroused – it does not cause a constant erection.

The onset can be slower after a heavy meal or alcohol. Age, liver or kidney function and other medicines can also change how long it lasts.

Cenforce 100 mg interactions

Drug interactions

• Never take with nitrates (nitroglycerin, isosorbide mononitrate or dinitrate) or “poppers” (amyl nitrite). The combination can cause a dangerous drop in blood pressure.
• Never take with riociguat, a medicine for pulmonary hypertension.
• Alpha-blockers for blood pressure or prostate problems (tamsulosin, doxazosin) can lower blood pressure further; your doctor may start you on a lower dose.
• Strong CYP3A4 inhibitors such as ritonavir, ketoconazole, itraconazole and clarithromycin raise sildenafil levels in the blood.
• Other ED or PAH medicines containing sildenafil, tadalafil or vardenafil should not be taken together.

Disease interactions

Tell your doctor before taking Cenforce 100 mg if you have or have had:

• Heart disease, heart attack, stroke or irregular heartbeat in the last 6 months
• Very low or uncontrolled high blood pressure
• Liver or kidney disease
• Retinitis pigmentosa or a past sudden vision loss (NAION)
• A deformed penis (such as Peyronie’s disease)
• Conditions that raise the risk of priapism: sickle cell anaemia, multiple myeloma, leukaemia
• Bleeding disorders or an active stomach ulcer

Food and alcohol interactions

• Grapefruit and grapefruit juice can increase sildenafil levels and side effects; avoid them.
• Alcohol in large amounts can lower blood pressure, cause dizziness and reduce the medicine’s effect.
• High-fat meals can delay the start of action by up to an hour.

Precautions and warnings

• Heart health: Sexual activity puts extra strain on the heart. If you are not fit enough for sex, do not take Cenforce 100 mg.
• Age 65 and over: Older men may need a lower starting dose, such as 25 mg.
• Driving: Cenforce can cause dizziness or vision changes. Do not drive or use machines until you know how it affects you.
• Women and children: Cenforce 100 mg is not meant for women or anyone under 18.
• Other medicines: Tell your doctor about every medicine, supplement and herbal product you take.

What if I miss a dose or take too much?

Cenforce 100 mg is taken only when needed, so there is no regular schedule and no missed dose. Never take two tablets to make the effect stronger.

Taking more than prescribed increases the risk of serious side effects such as low blood pressure, severe headache and a prolonged erection. If you take too much, contact a doctor or go to the nearest emergency department.
