Vigora 100 mg Tablet (Sildenafil)

What is Vigora 100 mg?

Vigora 100 mg is an oral medicine prescribed for men experiencing erectile dysfunction, a condition that makes it difficult to achieve or maintain an erection during sexual activity. Each tablet contains 100 mg of Sildenafil Citrate, an ingredient also found in Viagra.

Manufactured by Zydus Healthcare Limited, Vigora belongs to the phosphodiesterase type 5 (PDE5) inhibitor group. These medicines help support the natural erection process by increasing blood flow to the penis when a man is sexually stimulated.

Vigora 100 mg is the highest recommended sildenafil dose for treating erectile dysfunction. Doctors may prescribe this strength when a lower dose has not provided enough improvement and has been well tolerated.

However, 100 mg is not the usual starting dose. A medical professional should assess your health, existing medicines, and possible risks before recommending it.

What is Vigora 100 mg used for?

Vigora 100 mg is used to treat erectile dysfunction in adult men. Erectile dysfunction occurs when a man repeatedly has difficulty getting or keeping an erection suitable for sexual intercourse.

The medicine may help by:

• Supporting erections during sexual stimulation.
• Improving blood flow to the penis when arousal occurs.
• Helping maintain an erection long enough for sexual activity.

Vigora does not permanently cure erectile dysfunction or address every possible underlying cause.

It is not intended to increase sexual desire, treat premature ejaculation, or prevent sexually transmitted infections.

Men who experience ongoing erection problems should consult a healthcare professional because erectile dysfunction can sometimes be linked to diabetes, cardiovascular disease, or other health conditions.

How does Vigora 100 mg work?

Vigora 100 mg works by blocking an enzyme called phosphodiesterase type 5 (PDE5).

During sexual stimulation, the body releases nitric oxide into the tissues of the penis. This activates a chemical called cyclic guanosine monophosphate (cGMP), which helps relax the smooth muscles surrounding blood vessels.

As these muscles relax, more blood can enter the penis, allowing an erection to develop.

Normally, the PDE5 enzyme breaks down cGMP and reduces its effects. Sildenafil temporarily blocks this enzyme, allowing cGMP to remain active for longer.

This helps improve the blood flow needed to get and maintain an erection.

However, Vigora does not automatically produce an erection after swallowing the tablet. Sexual stimulation is necessary for the medicine to work.

How to take Vigora 100 mg

Vigora 100 mg should be taken exactly as prescribed by your doctor. The correct dose depends on your medical history, other medicines, and how your body responds to sildenafil.

Follow these instructions when taking the medicine:

• Dosage: Take only the amount prescribed by your healthcare professional.
• Timing: Sildenafil is usually taken approximately one hour before planned sexual activity.
• Administration: Swallow the tablet with a glass of water.
• Food: It can be taken with or without meals, although a high-fat meal may delay its effects.
• Frequency: Do not take sildenafil more than once in 24 hours.
• Dose limit: Never exceed 100 mg in a single day.

For most men, sildenafil treatment starts at 50 mg. The dose may be reduced to 25 mg or increased to 100 mg depending on effectiveness and side effects.

Some men require lower doses because of age, medical conditions, or interactions with other medicines.

Do not start with 100 mg or increase your current dosage without medical guidance.

How long does Vigora 100 mg take to work and last?

Vigora 100 mg generally starts working within 30 to 60 minutes after taking the tablet. Some men may notice its effects earlier, while others may need more time.

Sildenafil can be taken between 30 minutes and four hours before sexual activity, although approximately one hour beforehand is commonly recommended.

Its effects usually last around four to five hours.

This does not mean an erection remains for the entire period. Instead, the medicine supports the ability to develop an erection when sexual stimulation occurs.

Several factors can influence the timing and duration, including:

• Whether the tablet was taken after a heavy meal.
• Individual metabolism and age.
• Liver or kidney function.
• Other medicines being taken.
• Overall health and response to treatment.

A higher dose does not necessarily produce a longer-lasting effect, but it can increase the risk of side effects.

What are the side effects of Vigora 100 mg?

Like other sildenafil medicines, Vigora 100 mg may cause side effects. Not everyone experiences them, and many common reactions are mild and temporary.

Common side effects

The most frequently reported side effects include:

• Headache
• Facial flushing or warmth
• Stuffy or runny nose
• Indigestion
• Dizziness
• Nausea
• Blurred vision
• Increased sensitivity to light
• Temporary changes in colour vision

These reactions may occur because sildenafil affects blood vessels and certain enzymes elsewhere in the body.

Side effects can be more noticeable with higher doses.

If symptoms continue, become uncomfortable, or happen repeatedly, contact your doctor. A lower dose or different treatment may be more suitable.

Serious side effects

Although uncommon, sildenafil can sometimes cause serious reactions that require immediate medical attention.

These include:

• An erection lasting longer than four hours.
• Sudden loss or significant reduction of vision.
• Sudden hearing loss, sometimes with ringing in the ears.
• Chest pain, fainting, or severe dizziness.
• A serious allergic reaction involving swelling or breathing difficulty.

An erection lasting more than four hours is called priapism and may permanently damage penile tissue without prompt treatment.

Stop using the medicine and seek urgent medical care if you experience any of these symptoms. Do not take nitrate medicines for chest pain after sildenafil; tell emergency medical staff when you last took it.

Vigora 100 mg drug interactions

Certain medicines can interact with Vigora 100 mg and increase the risk of side effects. Always tell your doctor about prescription drugs, over-the-counter medicines, and supplements you use.

Medicines that should not be combined

• Nitrates: Nitroglycerin, isosorbide mononitrate, and isosorbide dinitrate can cause a dangerous fall in blood pressure when combined with sildenafil.
• Riociguat: This medicine is used for certain types of pulmonary hypertension and must not be combined with sildenafil.
• Other ED medicines: Combining sildenafil with tadalafil, vardenafil, or other erectile dysfunction medicines is not recommended.

Medicines requiring extra caution

• Alpha-blockers: Medicines such as tamsulosin and doxazosin can increase the risk of low blood pressure.
• Blood pressure medicines: Sildenafil may add to their blood-pressure-lowering effects.
• Certain antifungal medicines: Ketoconazole and itraconazole can increase sildenafil levels.
• Some antibiotics: Clarithromycin and erythromycin may affect how sildenafil is processed.
• HIV medicines: Ritonavir can significantly increase sildenafil exposure and requires specific dosage restrictions.

Your doctor may recommend a lower dose or another treatment if you take medicines that interact with sildenafil.

Precautions and warnings

Before using Vigora 100 mg, discuss your medical history with a healthcare professional.

Special care is needed if you have:

• Heart disease or an irregular heartbeat.
• A history of heart attack or stroke.
• Very low blood pressure or uncontrolled high blood pressure.
• Severe kidney or liver disease.
• Certain inherited eye conditions.
• A previous episode of sudden vision loss.
• Sickle cell anaemia, leukaemia, or multiple myeloma.
• Peyronie’s disease or another condition affecting the shape of the penis.
• An active stomach ulcer or bleeding disorder.

Sexual activity can place additional strain on the heart. Men who have been advised to avoid sexual activity because of cardiovascular problems should not use erectile dysfunction medicines without medical clearance.

Vigora 100 mg is not intended for children or for use as a sexual enhancement medicine by people without erectile dysfunction.

Vigora 100 mg and alcohol

Drinking excessive alcohol while taking Vigora may increase dizziness, headache, and low blood pressure.

Alcohol can also make it more difficult to achieve an erection, which may reduce the expected benefit of treatment.

Avoid heavy drinking when using sildenafil. Grapefruit products may also affect sildenafil levels, so discuss their use with your healthcare professional.

What happens if you miss a dose or take an overdose?

Missed dose

Vigora 100 mg is normally taken when needed rather than on a fixed daily schedule. Therefore, missing a dose is generally not an issue.

Never take an extra tablet to compensate for a missed opportunity or to make the medicine work more strongly.

Overdose

Taking more sildenafil than prescribed can increase the risk of severe headache, dizziness, low blood pressure, vision disturbances, and prolonged erections.

If you take too much, seek urgent medical advice even if symptoms are not immediately noticeable.

Do not attempt to manage a suspected overdose by taking other medicines.

Vigora 100 mg vs Viagra 100 mg

Vigora and Viagra contain the same active ingredient, Sildenafil Citrate, in the same 100 mg strength. Their mechanism of action is therefore similar, although manufacturing standards, regulatory approvals, and product availability may differ.

Having the same active ingredient does not automatically mean two branded products have identical regulatory approval status. Product approval should be checked in the country where it is supplied.

Alternatives to Vigora 100 mg

If Vigora is unsuitable or does not provide the expected results, your doctor may recommend another treatment.

Possible alternatives include:

• Sildenafil 25 mg or 50 mg: Lower strengths may be suitable for men who experience side effects with higher doses.
• Viagra: Another sildenafil-containing medicine used for erectile dysfunction.
• Tadalafil: A different PDE5 inhibitor with effects that may last up to 36 hours.
• Vardenafil: An alternative PDE5 inhibitor used for erectile dysfunction.
• Avanafil: A PDE5 inhibitor that may have a faster onset in some men.

The right medicine depends on personal health, response to treatment, and possible drug interactions.

Do not switch between erectile dysfunction medicines or combine them without consulting a doctor.

How to store Vigora 100 mg

Correct storage helps protect the medicine from moisture and environmental damage.

• Store according to the temperature instructions printed on the original packaging, generally below 30°C.
• Keep tablets in a cool, dry place.
• Avoid direct sunlight and excessive humidity.
• Leave tablets in their original packaging until needed.
• Keep the medicine away from children and pets.
• Check the expiry date before use.

Do not use tablets that appear damaged, discoloured, or have passed their expiry date.

When should you consult a doctor?

Consult a healthcare professional before starting Vigora 100 mg, especially if you have an existing medical condition or regularly take other medicines.

You should also seek medical advice if erection difficulties continue despite treatment, side effects become troublesome, or the medicine no longer works as expected.

A doctor can help identify possible causes of erectile dysfunction, such as diabetes, circulation problems, hormonal changes, or medication-related effects.

Treating an underlying condition may improve erectile function and overall health.
