In the treatment of erectile dysfunction (ED), the minimum effective dose is often the safest. VIAGRA 25 mg is the original, brand-name medication containing 25 mg of Sildenafil Citrate. This dosage is the lowest therapeutic dose and is ideal for men who require a mild, controlled effect to minimize the risk of side effects.
What is VIAGRA 25 mg?
VIAGRA 25 mg is a medication manufactured by Pfizer, containing 25 mg of Sildenafil Citrate.
1. Indication and target dosage
The 25 mg Sildenafil dose is intended for:
-
The safest start: Men trying Sildenafil for the first time who want to maximize the reduction of side effect risk.
-
Elderly Patients: Men over 65, for whom the recommended starting dose is often 25 mg due to slowed metabolism and increased sensitivity.
-
Underlying Conditions: Patients with mild renal or hepatic impairment, or those taking certain other medications (e.g., alpha-blockers, after consulting a doctor).
-
Mild ED: When erection problems are intermittent or predominantly psychological.
2. Dosing Corridor
25 mg is the minimum therapeutic dose. If VIAGRA 25 mg is well-tolerated but the effect is insufficient, the dose can be increased to 50 mg or 100 mg after consulting a doctor.
Detailed mechanism of action of VIAGRA 25 mg
The mechanism of action of VIAGRA 25 mg is based on Sildenafil being a selective inhibitor of the PDE5 enzyme.
-
Trigger: Sexual arousal causes the release of nitric oxide (NO).
-
Erectile Cycle: NO stimulates the formation of cyclic GMP (cGMP), which relaxes the smooth muscles of the penile blood vessels, causing them to widen. This ensures blood flow.
-
PDE5 Blockade: Sildenafil 25 mg blocks the enzyme that degrades cGMP. Blocking this enzyme allows cGMP to persist longer, enhancing the natural blood flow and ensuring a firm erection.
Key takeaway: The efficacy of VIAGRA 25 mg is dependent on the presence of sexual arousal. The drug is not an aphrodisiac.
Instructions for using VIAGRA 25 mg
Strict adherence to the instructions is necessary for safety and efficacy.
1. Dosage and timing of intake
-
Dosage: 25 mg (one tablet) – is the standard single dose. The maximum daily dose is 100 mg.
-
Method: Swallow the tablet whole with a full glass of water.
-
Timing: Take 45–60 minutes before planned sexual activity. The effect lasts 4–6 hours.
2. Influence of food and alcohol
-
Food: Taking VIAGRA 25 mg with a heavy, fatty meal can slow down the onset of action. It is recommended to take it on an empty stomach or after a light meal for a faster effect.
-
Alcohol: It is not recommended to combine Sildenafil intake with excessive amounts of alcohol, as this can enhance the vasodilating effect and increase the risk of headaches and hypotension.
Critical contraindications
Even at the minimum 25 mg dosage, the drug has strict contraindications.
-
Interaction with Nitrates: Absolutely forbidden! Taking VIAGRA 25 mg with any form of organic nitrates (Nitroglycerin) or nitric oxide donors ("poppers") causes a life-threatening drop in blood pressure.
-
Severe Cardiovascular Diseases: Recent heart attack or stroke (within 6 months), unstable angina, severe heart failure.
-
Blood Pressure: Persistent hypotension (pressure < 90/50 mmHg) or uncontrolled hypertension.
-
Liver and Kidneys: Severe hepatic or renal failure.
-
Eyes: Hereditary degenerative retinal diseases (retinitis pigmentosa).
Side effects of VIAGRA 25 mg (Minimal Risk)
The 25 mg dosage has the best safety profile. Side effects occur extremely rarely and are very mild at this dose.
-
Possible (rare): Mild headache, mild facial flushing, slight nasal congestion.
-
The visual disturbances characteristic of Sildenafil are virtually non-existent at this dose.
Immediate medical attention is required for: An erection that lasts longer than 4 hours (priapism), or sudden loss of vision/hearing.
Professional advice on using
-
Start with 25 mg: VIAGRA 25 mg is the most sensible way to begin treatment. If this dose is sufficient, you minimize health risks by avoiding higher dosages.
-
"Placebo" and Confidence Effect: For men with mild ED or ED related to anxiety/stress, 25 mg is often enough for psychological assurance, and the effect is fully satisfactory.
-
Flexibility: If 25 mg did not help, you can safely increase the dose to 50 mg next time.
