Fildena 100 mg Tablet (Sildenafil Citrate 100mg) — Complete Clinical and Patient Information Guide

Product Overview

Fildena 100 mg Tablet (Sildenafil Citrate 100mg) contains Sildenafil Citrate 100mg as its active pharmaceutical ingredient. It belongs to the phosphodiesterase type 5 (PDE5) inhibitor and is clinically indicated for erectile dysfunction (ED) in adult males. This information guide has been developed in accordance with YMYL (Your Money Your Life) standards, drawing on established pharmacological literature, regulatory prescribing information, and peer-reviewed clinical evidence to provide accurate, balanced, and medically responsible product information for patients and healthcare professionals.

Fildena 100mg contains Sildenafil Citrate 100mg, offering a trusted and clinically proven approach to erectile dysfunction management. Erectile dysfunction affects an estimated 150–322 million men globally and is associated with significant psychological burden, relationship impact, and reduced quality of life. PDE5 inhibitors like sildenafil have transformed the management of ED, offering a safe, effective, and non-invasive pharmacological option with a well-characterised benefit-to-risk profile established across decades of clinical use and post-marketing surveillance. Fildena is one of the most widely recognised sildenafil generic brands, manufactured by Fortune Healthcare with multiple strength options to cover the full spectrum of ED severity.

About Fildena 100mg and Its Active Ingredient

Sildenafil Citrate 100mg is the active pharmaceutical ingredient in Fildena 100mg. The drug belongs to the phosphodiesterase type 5 (PDE5) inhibitor, a pharmacological class with a well-established clinical evidence base spanning multiple decades of research and real-world clinical use. Understanding the pharmacology, appropriate use, and safety considerations of this medication is essential for achieving optimal therapeutic outcomes while minimising risks — the hallmarks of evidence-based prescribing and responsible patient self-care.

Before initiating therapy with Fildena 100mg, patients should disclose their complete medical history, all prescription and over-the-counter medications, herbal supplements, and known allergies to their prescribing physician or pharmacist. Medical supervision is particularly important for conditions classified as YMYL — where the consequences of improper use, incorrect diagnosis, or drug interactions could significantly impact health outcomes.

Mechanism of Action

Sildenafil citrate belongs to the phosphodiesterase type 5 (PDE5) inhibitor class. During sexual stimulation, nitric oxide (NO) is released from endothelial cells and non-adrenergic non-cholinergic (NANC) neurons in the corpus cavernosum. NO activates guanylate cyclase, triggering intracellular synthesis of cyclic guanosine monophosphate (cGMP). Elevated cGMP activates protein kinase G, which phosphorylates myosin light-chain kinase, reducing intracellular calcium and causing smooth muscle relaxation in penile arterial and trabecular smooth muscle. This relaxation allows arterial blood inflow into the corpus cavernosum while venous outflow is restricted by the tunica albuginea, producing an erection. Phosphodiesterase type 5 degrades cGMP, terminating the erection signal. Sildenafil competitively inhibits PDE5 with high selectivity, preventing cGMP breakdown and thereby amplifying and prolonging the physiological erection response to sexual stimulation. Sildenafil does not directly cause erections — it potentiates the natural erectile response and requires sexual arousal to be effective. Peak plasma concentration is reached 30–120 minutes after oral administration; duration of action is 4–6 hours.

A clear understanding of the mechanism of action helps explain why this medication must be used under specific conditions — why timing relative to meals or sexual activity matters, why certain drug combinations are dangerous, and why the full course of treatment is necessary for maximum benefit. Healthcare providers use mechanistic knowledge to individualise therapy and anticipate interactions.

Clinical Indications

Fildena 100 mg Tablet (Sildenafil Citrate 100mg) is indicated for:

• Primary indication: erectile dysfunction (ED) in adult males
• Confirmed diagnosis required: Self-diagnosis and self-treatment of conditions managed by prescription medications is strongly discouraged. A qualified physician or specialist should confirm the diagnosis and determine whether this medication is appropriate for the individual patient’s circumstances.
• Treatment goals: The prescribing physician will establish clear therapeutic endpoints — symptom relief, functional improvement, laboratory targets, or lesion clearance — and will monitor response and adjust therapy accordingly.

Dosage and Administration

Take Fildena 100mg orally 30–60 minutes before sexual activity. High-fat meals delay onset by 60+ minutes — take on an empty stomach or after a light meal for fastest effect. Do not exceed one dose per 24 hours. Elderly patients or those with hepatic impairment: start at 25mg.

Adherence to the prescribed dosing schedule is critical for achieving therapeutic efficacy and minimising the risk of adverse effects. Patients who are uncertain about their dosing regimen should contact their prescribing physician or pharmacist before making any changes. Never adjust the dose or stop therapy without medical advice.

Who Should Use Fildena 100mg

Fildena 100mg is appropriate for adult patients who have been diagnosed by a qualified healthcare professional with the conditions listed above and for whom this specific formulation has been prescribed or recommended. Patients with the relevant confirmed diagnosis who have no contraindications to the active ingredient are appropriate candidates.

Contraindications — Who Should Not Use Fildena 100mg

Absolute contraindications: Any form of organic nitrate (glyceryl trinitrate/nitroglycerin, isosorbide mononitrate, isosorbide dinitrate, amyl nitrite/poppers) — the combination causes unpredictable, potentially life-threatening hypotension through additive cGMP-mediated vasodilation. Soluble guanylate cyclase stimulators (riociguat). Recent myocardial infarction or stroke (within 3–6 months). Unstable angina. Severe cardiac failure (NYHA Class III/IV). Significant hepatic impairment. Hypersensitivity to the active ingredient or excipients. Men for whom sexual activity is medically inadvisable due to cardiovascular risk. Non-arteritic anterior ischaemic optic neuropathy (NAION) in one eye — risk of second eye involvement.

Patients should inform their healthcare provider of all medical conditions and medications before starting Fildena 100mg. Self-medication without medical supervision — particularly for prescription medications — carries significant risks including delayed diagnosis of underlying conditions, inappropriate drug use, and preventable adverse effects or drug interactions.

Drug Interactions

Nitrates (all forms): absolute contraindication — potential fatal hypotension. Alpha-blockers (tamsulosin, alfuzosin, doxazosin): additive hypotension — use lowest dose of PDE5 inhibitor and allow ≥4-hour interval if co-prescribed. CYP3A4 inhibitors (ketoconazole, itraconazole, ritonavir, clarithromycin, erythromycin): significantly increase PDE5 inhibitor plasma levels — reduce PDE5 inhibitor dose (typically 25mg sildenafil maximum). Grapefruit juice: inhibits CYP3A4, increasing sildenafil exposure — avoid. Antihypertensive agents: additive blood pressure reduction — monitor. Alcohol: additive vasodilation and hypotension — advise moderation. Other PDE5 inhibitors: never combine.

Before starting Fildena 100mg, perform a complete medication review with a pharmacist or physician. Drug interactions can be clinically significant and potentially dangerous. Many interactions can be managed by dose adjustment, timing modification, or alternative drug selection — but only when identified and evaluated by a qualified professional.

Adverse Effects and Side Effects

Very common (>10%): Headache (most frequent, affecting up to 28% of patients — due to NO-mediated vasodilation in cephalic vessels), facial flushing, and nasal congestion.

Common (1–10%): Dyspepsia, dizziness, and visual disturbances (transient colour tinge or blurred vision — more common with sildenafil due to partial PDE6 inhibition in retinal photoreceptors). Myalgia and back pain more commonly reported with tadalafil (PDE11 activity in skeletal muscle).

Uncommon but important: Hypotension — particularly with concurrent alpha-blocker use, antihypertensive therapy, or alcohol consumption. Priapism — prolonged erection lasting more than 4 hours is a urological emergency requiring immediate medical attention to prevent ischaemic damage to erectile tissue. Non-arteritic anterior ischaemic optic neuropathy (NAION) — rare but serious; risk factors include optic disc anatomy (small cup-to-disc ratio), age, hypertension, diabetes, hyperlipidaemia, and smoking. Sudden sensorineural hearing loss — reported post-marketing, mechanism unclear. Severe skin reactions (Stevens-Johnson syndrome, exfoliative dermatitis) — very rare.

Not all patients experience side effects, and many effects are dose-dependent, transient, or manageable with appropriate supportive measures. Patients should be educated about which side effects require urgent medical attention (severe allergic reactions, priapism for ED medications, signs of intracranial hypertension with retinoids) versus those that are expected and manageable (initial dryness with isotretinoin, retinisation with tretinoin).

Special Population Considerations

Cardiovascular assessment: All men presenting for PDE5 inhibitor therapy should have their cardiovascular fitness for sexual activity assessed. Men in the intermediate cardiac risk category (multiple CV risk factors, stable angina, recent MI >3 months, NYHA Class II heart failure) should be reviewed by a cardiologist before prescribing. Low cardiac risk patients may receive PDE5 inhibitors without further investigation.

Renal impairment: No dose adjustment required for mild-moderate impairment. Sildenafil and vardenafil: start at 25mg in severe renal impairment. Tadalafil: 5mg maximum dose in severe renal impairment (CrCl <30ml/min). Hepatic impairment: Reduce dose by 50% in moderate hepatic impairment (Child-Pugh B). Avoid in severe hepatic impairment (Child-Pugh C).

Elderly (≥65 years): Start at 25mg sildenafil or 50mg vardenafil due to reduced clearance and increased sensitivity. Tadalafil requires no age-based dose adjustment but lower starting doses may be appropriate.

Diabetes mellitus: ED is extremely common in diabetic men, and all three PDE5 inhibitors are effective though response may be somewhat lower than in non-diabetic men — dose titration to maximum tolerated dose may be required.

Frequently Asked Questions

Q: How should I store this medication?
A: Store at room temperature (15–25°C), away from direct sunlight, heat, and moisture. Keep in the original packaging out of reach of children. Do not use after the expiry date.

Q: What should I do if I miss a dose?
A: Take the missed dose as soon as you remember, unless it is nearly time for the next scheduled dose. Do not double-dose. For as-needed medications (PDE5 inhibitors, dapoxetine), the concept of a missed dose does not apply — take when required before sexual activity.

Q: Can I stop this medication abruptly?
A: For most topical acne treatments, stopping does not cause withdrawal, though acne may gradually return. For isotretinoin, complete the prescribed course for maximum benefit. For oral antibiotics, complete the full prescribed course. For PDE5 inhibitors, these are as-needed — no tapering required.

Q: What makes Fildena different?
A: Fildena is manufactured by Fortune Healthcare, a reputable Indian pharmaceutical company. Fildena tablets are available in multiple strengths (25mg, 50mg, 100mg, 120mg, 150mg) and formulations (standard tablets, sublingual, chewable) — providing dosing flexibility across a wide range of patient needs and ED severity.
