Everything You Need to Know About Sildenafil
How Does Sildenafil Work?
Sildenafil belongs to a class of medicines called PDE5 inhibitors. It works by increasing blood flow to the penis when you become sexually aroused. The medication blocks an enzyme called phosphodiesterase type 5, which allows blood vessels to relax and widen. It's important to understand that sildenafil doesn't cause automatic erections - sexual stimulation is still required for the medication to be effective.
Dosages and How to Take Sildenafil
Sildenafil tablets are available in three strengths: 25mg, 50mg, and 100mg. Most men start with 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if 50mg isn't sufficiently effective. You should take only one tablet within any 24-hour period. Food, particularly fatty meals, can delay how quickly the medication works.
Branded Viagra vs Generic Sildenafil
Both contain the same active ingredient - sildenafil citrate - and work identically. Viagra is the original branded version manufactured by Pfizer, while generic sildenafil offers the same therapeutic benefits at a lower cost. At EverydayMeds, you can choose between branded Viagra and generic sildenafil during checkout, depending on your preference and budget. Both require the same prescription process and clinical assessment.
Common Side Effects and Safety
Most men tolerate sildenafil well, but some may experience side effects including headaches, flushing, indigestion, nasal congestion, or dizziness. These are usually mild and temporary. More serious side effects are rare but require immediate medical attention, such as prolonged erections lasting over four hours, sudden vision or hearing loss, or chest pain. Always inform your prescriber about current medications and medical conditions during your consultation.
Who Cannot Take Sildenafil?
Sildenafil isn't suitable for everyone. You cannot take sildenafil if you're using nitrate medications (such as GTN spray), have severe heart disease, recent heart attack or stroke, severe liver problems, or very low blood pressure. The online consultation process helps identify any contraindications or potential drug interactions to ensure sildenafil is safe for you to use.
