Step-by-Step Sildenafil Usage Guide

Sildenafil Dosage Guidelines

Official MHRA-recommended dosing:

Key dosage rules:

• Never exceed 100mg in 24 hours
• Take only once per day
• Do not combine with other ED treatments

Who Should Take Sildenafil

Sildenafil is appropriate for:

• Adult men (18+) diagnosed with erectile dysfunction
• Those with physical or psychological causes of ED
• Patients without contraindications (see next section)
• Those who can achieve erections with sexual stimulation
• Patients with stable cardiovascular status (cleared by doctor)

According to the PIL: "Sildenafil is a treatment for adult men with erectile dysfunction, sometimes known as impotence. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity."

Who Should Not Take Sildenafil

• Allergy: To sildenafil or any tablet ingredients
• Nitrate users: Taking medications for angina (chest pain)
• Poppers users: Using nitric oxide donors like amyl nitrite
• Riociguat users: For pulmonary hypertension
• Severe heart/liver problems: Including recent heart attack or stroke
• Low blood pressure: Or uncontrolled hypertension
• Certain eye conditions: Retinitis pigmentosa or history of NAION
• Women and children: Not indicated for use

The PIL states: "You should not take Sildenafil if you do not have erectile dysfunction" and "You should not take Sildenafil if you are a woman."

When to Take Sildenafil

Optimal timing considerations:

PIL guidance: "You should take Sildenafil about one hour before you plan to have sex. Swallow the tablet whole with a glass of water."

Optimal Timing and Administration

To maximise effectiveness:

• 60 minutes before: Ideal timing window
• 30-120 minute range: Effective period
• With food: Allowed but delays onset
• Without food: Optimal for fastest action
• Alcohol limit: ≤2 units recommended

Administration notes: "Sildenafil will only help you get an erection if you are sexually stimulated."

Dosage Adjustments for Special Cases

What to Avoid When Taking Sildenafil

• Nitrate medications: Including angina treatments
• Recreational "poppers": Amyl nitrite compounds
• Grapefruit juice: Inhibits drug metabolism
• High-fat meals: Delays absorption
• Excessive alcohol: >3 units reduces efficacy
• Other ED medications: Tadalafil, vardenafil, etc.

Common Misconceptions About Sildenafil Usage

• "Take when needed": Requires 60-min advance planning
• "Higher doses work better": 100mg is maximum effective dose
• "Works without stimulation": Requires sexual arousal
• "Daily use improves results": Only take before planned activity
• "Crushing speeds up action": Tablets must be swallowed whole

The NHS states: "Do not take more than one dose per day" and "Sildenafil will only help if you're sexually aroused".

Missed Dose Instructions

According to MHRA guidance:

• If forgotten before activity: Skip the dose
• Never take double dose to compensate
• Take next dose at least 24 hours later
• Do not take more than one tablet daily
