How Long Does Sildenafil Work and What Side Effects Occur?
Sildenafil Duration: What to Expect
Sildenafil typically remains effective for 4-6 hours after taking a dose, though this varies between individuals. The medication reaches peak concentration in your bloodstream within 30-60 minutes, with effects gradually diminishing over the following hours. This duration applies to both generic sildenafil and branded Viagra, as they contain identical active ingredients.
It's important to understand that sildenafil doesn't cause continuous erection for 4-6 hours. Instead, it maintains your ability to achieve erections when sexually aroused during this timeframe. The actual erection should subside naturally after sexual activity ends.
Common Sildenafil Side Effects
Most men tolerate sildenafil well, experiencing mild side effects that often improve with continued use. The most frequently reported side effects include headache (affecting approximately 16% of users), facial flushing (10%), and indigestion (7%). These occur because sildenafil affects blood vessels throughout your body, not just in the genital area.
Nasal congestion, back pain, and muscle aches may also occur, typically resolving within a few hours. Visual disturbances, such as slight colour vision changes or increased light sensitivity, affect fewer than 3% of users and are usually temporary.
Comparing Sildenafil Options: Generic vs Branded
Both generic sildenafil and Viagra contain identical active ingredients and produce the same duration of action and side effect profiles. The primary difference lies in cost and appearance. Generic sildenafil typically costs significantly less whilst providing equivalent effectiveness and safety.
EverydayMeds offers both options at checkout, allowing you to choose based on your preferences. Some patients prefer branded Viagra for familiarity, whilst others opt for generic sildenafil for better value. Both undergo rigorous quality testing and regulation by the MHRA.
Managing Side Effects Effectively
If you experience side effects, several strategies may help. Taking sildenafil on an empty stomach can reduce indigestion, whilst staying well-hydrated may minimise headaches. Avoiding alcohol and fatty meals can improve both effectiveness and tolerability.
Most side effects are dose-related, meaning they may improve if your prescriber adjusts your dose from 100mg to 50mg or 25mg. Our clinical team can discuss dosage adjustments during your consultation to optimise both effectiveness and comfort.
When to Seek Medical Advice
Whilst serious side effects are rare, certain symptoms require immediate medical attention. Contact emergency services if you experience chest pain, prolonged erection lasting over 4 hours, or sudden vision or hearing loss. These situations, though uncommon, need prompt medical evaluation.
Contact our clinical team if you experience persistent side effects that don't improve after several doses, or if the medication becomes less effective over time. We can review your treatment and discuss alternatives or adjustments.
