Sildigra Soft 50 delivers 50 mg of sildenafil in a chewable tablet.

Sildenafil is the original PDE-5 inhibitor, approved in 1998.

It is the molecule inside Viagra.

RSM Enterprises of India manufactures and exports this brand.

The tablet is mint flavoured and chewed rather than swallowed whole.

No water is required, which suits men who dislike swallowing pills.

A blister of 10 tablets is the standard pack.

The Sildigra family also includes 25 mg and Sildigra Soft100 mg strengths.

The label names 50 mg as the recommended dose for most men.

Sildenafil differs from tadalafil here, where the entry dose is much smaller.

From 50 mg a doctor can move up to 100 mg or down to 25 mg.

The decision rests on how well it worked and how well it was tolerated.

In trials, 74 percent of men on 50 mg reported improved erections.

On placebo the figure was 24 percent.

Moving to 100 mg lifted that to 82 percent, but side effects rose too.

It improves blood flow into the penis when you are aroused.

The result is an erection that comes more easily and holds better.

Trial diaries showed roughly two thirds of attempts succeeding.

On placebo, roughly one fifth succeeded.

It produces nothing at all without sexual stimulation.

It does not create desire, and it does not raise libido.

It does not delay ejaculation or extend how long sex lasts.

It does not alter penis size or shape.

It does not affect sperm movement or shape.

Less than one thousandth of a percent of the dose reaches semen.

It does not cure the cause of the problem.

It offers no protection against HIV or other infections.

It is not for women, and not for anyone under 18.

Sexual stimulation releases nitric oxide into the erectile tissue.

Nitric oxide switches on an enzyme called guanylate cyclase.

That enzyme raises levels of a messenger called cGMP.

cGMP relaxes the smooth muscle inside the corpus cavernosum.

Relaxed muscle lets blood flow in and fill the tissue.

An enzyme called PDE-5 continuously degrades cGMP.

Sildenafil inhibits PDE-5, so cGMP survives longer.

The erection therefore forms more readily and lasts longer.

Sildenafil has no direct relaxing effect on erectile tissue by itself.

At recommended doses it has no effect without sexual stimulation.

The drug amplifies a natural process. It does not replace one.

PDE-5 has relatives elsewhere in the body.

PDE-6 lives in the retina and handles light signalling.

Sildenafil is only about 10 times more selective for PDE-5 than PDE-6.

Tadalafil, by comparison, is 700 times more selective.

That narrow margin is why colour changes are commoner with sildenafil.

At 50 mg, 2 men in 100 reported them. At 100 mg, 11 in 100 did.

The effect is mild, temporary and peaks alongside blood levels.

Men describe a blue or green tinge, glare sensitivity, or slight blurring.

Testing found no change to visual sharpness or eye pressure.

PDE-3 governs how forcefully the heart contracts.

Sildenafil is roughly 4,000 times more selective for PDE-5 than PDE-3.

That wide margin limits direct effects on heart muscle.

It does not remove the blood pressure effect, which is separate.

Absorption is rapid. Peak levels arrive in 30 to 120 minutes.

Sixty minutes is the median.

Roughly 41 percent of a dose reaches the bloodstream.

A high-fat meal delays that peak by about 60 minutes.

It also cuts the peak level by about 29 percent.

This is a real difference from tadalafil, which food does not affect.

Both sildenafil and its active metabolite clear with a half-life near 4 hours.

The liver handles this, mainly via CYP3A4 with CYP2C9 as a minor route.

About 80 percent leaves in stool, about 13 percent in urine.

Confirm with a doctor that 50 mg suits your circumstances.

Check the blister is sealed and the expiry date has not passed.

Chew the tablet thoroughly before swallowing it.

No water is needed, though you may drink some if you prefer.

Aim for about one hour before sex. That is when it works best.

Anywhere from 30 minutes to 4 hours ahead is acceptable.

Skip the heavy fatty meal beforehand if you can.

Let arousal happen. The tablet does nothing without it.

Take one only, and none again for 24 hours.

Fried food, rich curries, cheese-heavy dishes and creamy sauces all count.

Eating one of those first pushes the peak back roughly an hour.

It also lowers that peak by around a third.

The tablet still works. It simply works later and less strongly.

A lighter meal, or an empty stomach, gives the most reliable result.

This is worth telling customers. Many blame the tablet for a heavy dinner.

The effect is measurable for up to about 4 hours.

It is noticeably stronger near the 2-hour mark than at 4 hours.

This is a shorter window than tadalafil offers, and that is by design.

It suits men who prefer a medicine that clears quickly.

It suits planned occasions less well than an all-weekend option would.

There is no schedule here, so nothing can be missed.

Never take a second tablet because the first seemed weak.

Doses far above the maximum produced the same effects, more often and more severely.

If you have swallowed several, go to a hospital emergency department.

Dialysis does not help, because sildenafil binds tightly to blood proteins.

Any nitrate medicine, taken regularly or occasionally.

Nitroglycerin, isosorbide mononitrate and isosorbide dinitrate all qualify.

Sprays, patches and ointments qualify equally.

Street nitrites known as poppers, including amyl and butyl nitrite.

Riociguat, or any other guanylate cyclase stimulator.

Known allergy to sildenafil or to anything in the tablet.

Situations where a doctor has judged sex itself unsafe for your heart.

Use by women, or by anyone under 18.

Any heart attack, angina, irregular heartbeat or heart failure.

Heart surgery within the past six months.

Raised pressure in the lung arteries.

Any stroke, at any time.

Blood pressure that is low, or high and uncontrolled.

A penis that is bent or structurally unusual.

Any past erection lasting beyond four hours.

Sickle cell anaemia, multiple myeloma or leukaemia.

Retinitis pigmentosa, which runs in families.

Any episode of severe vision loss, particularly NAION.

Bleeding problems, or a history of stomach ulcers.

Liver problems of any severity.

Kidney problems, or dialysis treatment.

Every medicine you take, prescription or otherwise.

Avoid a high-fat meal in the hour before your dose.

Grapefruit juice raises sildenafil levels. Avoid it.

On alcohol, the evidence is narrower than people assume.

A study gave sildenafil 50 mg with alcohol at 0.5 g per kilogram.

Blood alcohol reached about 0.08 percent.

Sildenafil did not worsen alcohol’s effect on blood pressure.

No postural dizziness was reported in that study.

The 100 mg dose was never tested this way, so caution still applies.

Alcohol independently makes erections harder to achieve.

Never combine this tablet with poppers. See the contraindications.

Do I have a prescription from a doctor who knows my history?

Am I certain I take no nitrate in any form, including a spray?

Am I free of riociguat and of poppers?

Am I under 65, with healthy liver and kidneys?

If not, has my doctor considered starting me at 25 mg?

Am I stable on any alpha-blocker I take?

Am I clear of erythromycin, ketoconazole, itraconazole and ritonavir?

Has my heart been judged fit for sexual activity?

Have I avoided a heavy fatty meal this evening?

Has a full 24 hours passed since my last tablet?

Do I know which symptoms mean stop and get help?

Headache is by far the commonest complaint at every dose.

One man in five reported it at 50 mg.

Flushing affects roughly one in five at this strength too.

Indigestion climbs steeply above 50 mg, from 9 percent to 17.

Vision changes climb even more steeply, from 2 percent to 11.

Those two columns are the strongest argument for not jumping to 100 mg.

Across trials, 2.5 percent of men stopped because of side effects.

On placebo, 2.3 percent stopped. The difference was not significant.

Sildenafil did not meaningfully affect warfarin or tolbutamide.

At 50 mg it did not add to the bleeding time caused by aspirin.

It did not alter the levels of saquinavir or ritonavir themselves.

Show your doctor a written list of everything you take.

An erection that has not gone after four hours.

Four hours is the point of action. Do not wait for pain.

Untreated, this can permanently damage the penis and end potency.

Sudden loss of vision in one eye or both.

Sudden loss or reduction of hearing, with or without ringing.

Chest pain, dizziness or nausea after starting sex. Stop at once.

Fainting, or feeling you are about to faint.

Slurred speech, facial droop or weakness on one side.

Swelling of the face, lips, tongue or throat.

A spreading rash, particularly with blistering or peeling.

A seizure.

50 mg is the dose the label recommends for most men.

No compromise is involved in starting here.

74 percent of men on 50 mg reported improved erections in trials.

The placebo figure was 24 percent.

Sildenafil has the longest safety record of any ED drug, since 1998.

Over 3,700 patients took it in pre-marketing trials alone.

It worked across organic, psychological and mixed causes.

In diabetes-related ED, 57 percent reported improvement versus 10 on placebo.

After spinal cord injury, 83 percent reported improvement versus.

After radical prostatectomy, 43 percent improved versus 15.

Chewing removes the need for water, which some men strongly prefer.

The mint flavour masks the taste of the drug.

The 4-hour window suits men who want a medicine that clears quickly.

25 mg and 100 mg exist in the same brand, so the dose can be adjusted.

The claim of nil side effects is false. See Section 6 for the real figures.

No published study shows this chewable absorbs faster than a tablet.

It does not affect libido, despite one page saying so.

It is not FDA approved as a brand, though the molecule is.

The shorter window is a genuine trade-off, not purely an advantage.

Store at 25 °C. Brief excursions from 15 to 30 °C are permitted.

The patient leaflet gives a narrower range of 20 to 25 °C.

Keep tablets sealed in the blister until you take one.

A chewable absorbs moisture more readily than a coated tablet.

Humidity can soften it, make it sticky, or spoil the flavour.

Keep it away from direct sun and heat sources.

Do not refrigerate, and never freeze.

Bathrooms and cars are the two worst storage places.

Keep all medicines out of children’s reach.

A mint-flavoured chewable can be mistaken for a sweet. Store it securely.

Discard tablets that are soft, discoloured, sticky or crumbling.

Do not use past the printed expiry date.

Return unwanted tablets to a pharmacy.

Never give them to anyone else.

General information only. Not a substitute for medical advice.

Sildenafil is a prescription medicine wherever it is licensed.

This medicine does have side effects. Any claim otherwise is false.

Never adjust your own dose without medical direction.

100 mg is the approved ceiling for erectile dysfunction.

An erection lasting beyond four hours needs emergency care.

Tell any emergency team the exact time you took your dose.

The Sildigra brand is not FDA, EMA or MHRA approved.

Read the leaflet supplied with your own product.
