Complete Quick Reference Guide for Sildenafil Tablets
What Are Sildenafil Tablets?
Sildenafil tablets contain the same active ingredient as branded Viagra but are available as a generic medication at a lower cost. These prescription-only medicines work by increasing blood flow to the penis when sexually aroused, helping men achieve and maintain erections suitable for sexual activity. EverydayMeds offers both generic sildenafil and branded Viagra, allowing patients to choose their preferred option at checkout.
The medication belongs to a class of drugs called PDE5 inhibitors, which block the phosphodiesterase type 5 enzyme. This action helps relax blood vessels and improve circulation to the penile tissue during sexual stimulation.
Available Strengths and Dosing
Sildenafil tablets are available in three strengths: 25mg, 50mg, and 100mg. The typical starting dose is 50mg, taken approximately 30-60 minutes before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects or increase to 100mg if 50mg proves insufficient.
The maximum dose is one tablet per 24-hour period. Taking sildenafil on an empty stomach or after a light meal can help it work more quickly, as high-fat meals may delay the onset of action. The effects can last 4-6 hours, though this doesn't mean an erection will persist for this duration.
How Quickly Does Sildenafil Work?
Most men find sildenafil begins working within 30-60 minutes of taking the tablet. However, sexual stimulation is still required for the medication to be effective. The tablet doesn't cause automatic erections but rather helps the body's natural response to sexual arousal.
For optimal timing, take your prescribed dose about one hour before planned sexual activity. Some men may notice effects as early as 15-30 minutes, whilst others may need to wait up to 90 minutes, particularly if taken with food.
Common Side Effects Quick Reference
The most frequently reported side effect is headache, affecting more than 1 in 10 men. Other common side effects include facial flushing, indigestion, nasal congestion, dizziness, and temporary visual changes such as a blue tinge to vision or increased light sensitivity.
These side effects are typically mild and temporary, often becoming less noticeable with continued use. If you experience persistent or severe side effects, consult your prescriber about potentially adjusting your dose.
Important Safety Considerations
Never take sildenafil with nitrate medications such as GTN spray or isosorbide tablets, as this combination can cause dangerous drops in blood pressure. Recreational drugs containing nitrates ("poppers") must also be avoided completely.
Men taking alpha-blockers for prostate problems or blood pressure medications should inform their prescriber, as dose adjustments may be necessary. If you have heart conditions, recent stroke or heart attack history, or severe liver problems, sildenafil may not be suitable for you.
Effectiveness and Expectations
Clinical studies show sildenafil helps approximately 70-80% of men with erectile dysfunction. The medication may become more effective over several uses as you and your body adjust to the treatment. It's important to maintain realistic expectations - sildenafil helps with the physical aspects of achieving erections but doesn't increase sexual desire or arousal.
If the medication doesn't work effectively on the first few attempts, discuss with your prescriber whether a dose adjustment might help before considering it ineffective.
Storage and Handling
Store sildenafil tablets in their original packaging below 30°C, away from moisture and direct sunlight. Keep all medications out of reach of children and never share your prescription with others. Check expiry dates regularly and dispose of expired medications safely through your local pharmacy.
When to Seek Medical Advice
Seek immediate medical attention if you experience an erection lasting more than 4 hours (priapism), sudden vision or hearing loss, chest pain during sexual activity, or signs of severe allergic reaction. These are rare but serious side effects requiring urgent treatment.
Contact your prescriber if you're experiencing persistent side effects, the medication isn't working effectively after several attempts, or if you develop new medical conditions or start new medications that might interact with sildenafil.
