Fildena 100 mg Tablet (Sildenafil)

What is Fildena 100 mg?

Fildena 100 mg is an oral medication used to treat erectile dysfunction (ED) in adult men. Each tablet contains 100 mg of Sildenafil Citrate, the same active ingredient found in Viagra, the original branded sildenafil medicine.

It belongs to a group of medicines called phosphodiesterase type 5 (PDE-5) inhibitors. These medicines help improve blood circulation in the penis, making it easier to achieve and maintain an erection during sexual stimulation.

Fildena is manufactured by Fortune Healthcare in India and is marketed as a generic alternative to Viagra. However, Fildena itself is not approved by the US FDA, and its regulatory status may differ between countries.

The 100 mg strength is the maximum recommended single dose of sildenafil for ED. Doctors generally begin treatment with 50 mg and may adjust the dose according to individual response and tolerance.

Fildena 100 mg should only be used after consulting a healthcare professional.

What is Fildena 100 mg used for?

Fildena 100 mg contains sildenafil, which is used to treat erectile dysfunction in adult men. ED is a condition in which a man repeatedly finds it difficult to get or maintain an erection firm enough for sexual activity.

Sildenafil treatment may help by:

• Improving the ability to achieve an erection during sexual stimulation.
• Helping maintain an erection suitable for sexual activity.
• Supporting erectile function in men diagnosed with ED.

Fildena 100 mg does not permanently cure erectile dysfunction, increase sexual desire, or work without sexual stimulation.

It also does not prevent pregnancy or protect against sexually transmitted infections.

How does Fildena 100 mg work?

Fildena 100 mg works by supporting the natural process that produces an erection. Its active ingredient, Sildenafil Citrate, blocks an enzyme called PDE-5.

During sexual stimulation, the body releases nitric oxide in the penile tissues. This increases the level of a chemical called cyclic guanosine monophosphate (cGMP).

The cGMP chemical relaxes smooth muscles around blood vessels, allowing more blood to enter the penis.

Normally, the PDE-5 enzyme breaks down cGMP. Sildenafil slows this process, helping the blood vessels remain relaxed so an erection can develop and be maintained.

The medicine does not create sexual desire or produce an erection automatically. Sexual stimulation is necessary for it to work.

When sexual stimulation ends, the erection usually goes away naturally.

How to take Fildena 100 mg

Take Fildena 100 mg exactly as prescribed by your doctor. The appropriate sildenafil dose depends on your health, current medications, treatment response, and possible side effects.

For most adults, the recommended starting dose of sildenafil is 50 mg. A doctor may increase it to 100 mg if needed and safely tolerated.

Follow these general instructions:

• Dose: Take only the sildenafil strength prescribed by your healthcare professional.
• Timing: Take it approximately 1 hour before sexual activity. Sildenafil may be taken between 30 minutes and 4 hours beforehand.
• How to take: Swallow the tablet whole with a glass of water.
• Food: It can be taken with or without food. A heavy or high-fat meal may delay its effect.
• Maximum dose: Do not take more than 100 mg or more than one prescribed sildenafil dose within 24 hours.
• Alcohol: Avoid excessive alcohol because it can increase dizziness and low blood pressure.

Do not take additional tablets if the medicine does not work as expected.

If you experience side effects or find the prescribed strength unsuitable, speak with your doctor about adjusting the dosage.

How long does Fildena 100 mg last?

Fildena 100 mg generally begins working within 30 to 60 minutes after taking it. Its erection-supporting effects commonly last approximately 4 to 5 hours, although this can vary.

During this period, an erection may occur when sexual stimulation is present. The medicine does not cause a continuous erection.

Food intake, age, metabolism, liver or kidney function, and other medicines can influence how quickly sildenafil works and how long its effects remain noticeable.

Missed dose and overdose

Fildena 100 mg is usually taken when needed before sexual activity, so there is generally no regular dosing schedule or missed dose.

Never take two tablets together or double the prescribed amount.

An overdose may cause severe headache, dizziness, low blood pressure, vision changes, or a prolonged erection.

If you take more sildenafil than prescribed, seek urgent medical advice. An erection lasting longer than four hours requires immediate emergency treatment.

Side effects of Fildena 100 mg

Like other sildenafil-containing medicines, Fildena 100 mg can cause side effects. Some men experience mild symptoms, while others may not notice any.

Side effects are more likely with higher doses or certain medication combinations.

Common side effects

Some commonly reported side effects include:

• Headache: Mild or moderate head pain.
• Flushing: Warmth or redness of the face.
• Indigestion: Stomach discomfort or acidity.
• Blocked nose: Nasal congestion or a runny nose.
• Dizziness: Feeling lightheaded.
• Back pain: Occasional back or muscle discomfort.
• Vision changes: Blurred vision, blue-tinted vision, or sensitivity to light.
• Nausea: Feeling sick or uncomfortable in the stomach.

Most common side effects are temporary. However, contact your healthcare provider if they continue, become severe, or affect daily activities.

Serious side effects – stop and get medical help

Although uncommon, sildenafil may cause serious reactions that need immediate medical attention.

Seek emergency help if you experience:

• An erection lasting longer than four hours (priapism).
• Sudden vision loss in one or both eyes.
• Sudden hearing loss or a significant hearing change.
• Chest pain or a severe irregular heartbeat.
• Fainting or severe dizziness.
• Facial swelling, breathing difficulty, or another serious allergic reaction.

Do not ignore these symptoms, as delayed treatment may lead to serious complications.

Interactions

Fildena 100 mg may interact with certain medicines, existing health conditions, food, and alcohol. Some interactions increase sildenafil levels in the blood, while others may cause a dangerous fall in blood pressure.

Drug interactions

Important medication interactions include:

• Nitrates: Nitroglycerin, isosorbide medicines, and recreational nitrite products called poppers must never be combined with sildenafil.
• Riociguat: This medicine must not be used with sildenafil because it can severely lower blood pressure.
• Alpha-blockers: Medicines such as tamsulosin and doxazosin may increase the risk of dizziness and low blood pressure.
• Other PDE-5 inhibitors: Do not combine sildenafil with tadalafil, vardenafil, avanafil, or another sildenafil product without medical direction.
• Ritonavir: This medication can greatly increase sildenafil exposure and requires a substantially reduced dosing schedule.
• Strong CYP3A4 inhibitors: Ketoconazole, itraconazole, and clarithromycin may increase sildenafil levels and the risk of side effects.

Disease interactions

Tell your doctor if you have:

• Heart disease, irregular heartbeat, or a recent heart attack or stroke.
• Very low blood pressure or uncontrolled high blood pressure.
• Severe liver or kidney problems.
• Retinitis pigmentosa or a history of sudden vision loss.
• Peyronie’s disease or another penile deformity.
• Sickle cell disease, leukaemia, or multiple myeloma.
• Bleeding disorders or an active stomach ulcer.

These conditions may require additional medical assessment, a lower dose, or an alternative treatment.

Food and alcohol interactions

• High-fat meals: May delay the start of sildenafil’s effect.
• Alcohol: Excessive consumption can increase dizziness and interfere with erectile function.
• Grapefruit: May increase sildenafil exposure and side effects, so discuss grapefruit consumption with your healthcare provider.

Precautions and warnings

Before using Fildena 100 mg, a healthcare professional should review your medical history and all medicines you currently take.

Important precautions include:

• Heart health: Sildenafil may be unsuitable if sexual activity is unsafe because of a serious heart condition.
• Age 65 and above: Older adults may need a lower starting dose, commonly 25 mg.
• Blood pressure: Sildenafil can lower blood pressure, particularly when combined with certain medications.
• Driving: Avoid driving or operating machinery if you experience dizziness or vision problems.
• Pregnancy and breastfeeding: Fildena 100 mg is not indicated for use during pregnancy or breastfeeding.
• Children: This medicine is not intended for anyone under 18.
• Other medicines: Tell your doctor about prescription medicines, non-prescription products, and herbal supplements.
