Erex Professional 100 Mg (Sildenafil Citrate)

Erex Professional is a dissolving tablet for erectile dysfunction (ED).

Each tablet contains 100 mg of sildenafil citrate.

Sildenafil belongs to the PDE-5 inhibitor drug class.

It helps adult men achieve and maintain a firm erection.

The tablet is placed under the tongue and allowed to dissolve.

No water is needed to take it.

It suits men who dislike swallowing tablets.

The active ingredient is identical to standard sildenafil tablets.

The medicine works only during sexual stimulation.

It does not increase sexual desire or libido.

It does not cure the underlying cause of ED.

It does not treat premature ejaculation.

It offers no protection against HIV or other STIs.

It is not a hormone, steroid, or aphrodisiac.

Erex Professional and Erex 100 mg is intended for adult men only.

Women and anyone under 18 must not use it.

ED can signal heart, hormonal, or vascular disease.

A full medical assessment should precede any ED treatment.

Sexual stimulation triggers nitric oxide release in penile tissue.

Nitric oxide activates an enzyme called guanylate cyclase.

This enzyme raises cyclic guanosine monophosphate (cGMP) levels.

cGMP relaxes smooth muscle in the corpus cavernosum.

Relaxed muscle allows penile arteries to widen.

Blood flows in and fills the erectile chambers.

Expanding tissue compresses the veins, trapping blood inside.

This produces and sustains a firm erection.

An enzyme called PDE-5 breaks cGMP down.

Rapid breakdown makes the erection fade too early.

Sildenafil blocks PDE-5, so cGMP stays elevated longer.

Blood flow is therefore maintained during sexual activity.

The tablet breaks down in saliva. A small amount may pass through the lining of the mouth. Most of the medicine is swallowed and absorbed in the gut. This is the same route as a conventional tablet.

PDE-5 enzymes in the penis become largely saturated at around 100 mg. Higher doses cannot block much more enzyme there.

PDE-6 is a related enzyme found in the retina. Sildenafil affects PDE-6 alongside PDE-5. This explains the blue-tinged vision some men notice.

Without sexual stimulation, no nitric oxide is released. The medicine then has nothing to act on.

Take one tablet 30 to 60 minutes before sexual activity.

The effect can last up to 4 to 5 hours.

Allow at least 24 hours after a dose before any nitrate.

A high-fat meal can delay onset by about one hour.

Dissolving tablets cannot be divided accurately.

Not applicable. This medicine is used only as needed.

Take the tablet exactly as your doctor prescribed.

Make sure your hands are clean and dry.

Remove one tablet from the blister just before use.

Place it under your tongue.

Allow it to dissolve completely.

Do not chew or crush the tablet.

Do not swallow it whole.

Swallow the dissolved medicine with your saliva.

Avoid drinking for a minute or two afterwards.

Take it 30 to 60 minutes before planned sexual activity.

Take it on an empty stomach for the fastest onset.

Avoid heavy or high-fat meals before dosing.

Sexual stimulation is required for the medicine to work.

The effect lasts around 4 to 5 hours.

Take no more than one tablet in 24 hours.

Do not combine it with any other ED medicine.

Do not take a second tablet if the first seems weak.

Do not share your tablets with anyone else.

Nitrates include glyceryl trinitrate and isosorbide mononitrate or dinitrate.

This covers nitrate sprays, patches, and sublingual tablets.

Nitrates plus sildenafil can cause a fatal drop in blood pressure. Never combine them. Allow at least 24 hours between a dose and any nitrate medicine.
