Understanding Viagra's Mechanism and Travel Planning
How Viagra Works in Your Body
Viagra contains sildenafil citrate, which belongs to a class of medicines called PDE5 inhibitors. When sexually aroused, your body naturally releases nitric oxide, which increases blood flow to the penis. Viagra works by blocking the PDE5 enzyme that normally breaks down this process, helping maintain increased blood flow. Importantly, Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective.
Timing and Effectiveness
Viagra typically begins working within 30-60 minutes of taking it on an empty stomach. The effects can last up to 4-6 hours, though this does not mean you will have an erection for this entire time. Taking Viagra with a large or fatty meal may delay its onset of action. For optimal results, many patients find taking it 1 hour before planned sexual activity works best.
Travel Considerations and Storage
When travelling with Viagra, keep tablets in their original packaging with your name on the prescription label. Store at room temperature away from moisture and heat. For international travel, carry a letter from your prescriber confirming your prescription. Time zone changes may affect your usual dosing schedule, so plan accordingly with your healthcare provider's guidance.
Dosage Options Available
Viagra is available in three strengths: 25mg, 50mg, and 100mg. Most patients start with 50mg, which can be adjusted based on effectiveness and any side effects experienced. Never take more than one dose in 24 hours, regardless of strength. At EverydayMeds, patients can choose between branded Viagra and generic sildenafil during checkout - both contain the same active ingredient.
Safety and Contraindications
Viagra is not suitable for everyone. It should never be taken with nitrate medications (used for chest pain) as this can cause dangerous blood pressure drops. Men with severe heart conditions, recent stroke or heart attack, or those taking certain medications may not be suitable candidates. All patients require a clinical assessment before prescription approval.
