Understanding Viagra's Mechanism and Troubleshooting
How Viagra Works in Your Body
Viagra contains sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When you become sexually aroused, your body naturally releases nitric oxide in the penis. This triggers increased levels of cGMP, a chemical that relaxes blood vessels and improves blood flow. The enzyme PDE5 normally breaks down cGMP, but Viagra blocks this process, allowing enhanced blood flow to continue and helping achieve an erection.
Common Issues and Solutions
If Viagra is not working as expected, several factors may be involved. Food, particularly fatty meals, can delay absorption and reduce effectiveness. Taking Viagra on an empty stomach or 2 hours after eating may improve results. Alcohol can also interfere with the medication's effectiveness and should be limited. Stress, anxiety, and relationship issues can impact sexual arousal, which is essential for Viagra to work properly.
Dosage Troubleshooting
The standard starting dose is 50mg, taken approximately one hour before sexual activity. If this proves insufficient, your prescriber may increase the dose to 100mg or reduce it to 25mg if you experience side effects. Never take more than one dose in 24 hours or exceed the prescribed amount. Some men find 25mg sufficient, particularly those taking certain medications or with underlying health conditions.
Choosing Between Viagra and Sildenafil
Both branded Viagra and generic sildenafil contain the same active ingredient and work identically. The main difference is cost - generic sildenafil typically costs less whilst providing the same clinical benefits. At EverydayMeds, patients can choose between branded or generic options during checkout following their clinical consultation. Both require the same prescription process and safety checks.
When to Seek Medical Advice
Contact a healthcare professional if you experience chest pain, sudden vision loss, or an erection lasting more than 4 hours. If Viagra stops working after previously being effective, or if you develop new health conditions, consult with your prescriber. Regular medication reviews help ensure continued safety and effectiveness. Never combine Viagra with nitrate medications or recreational drugs containing nitrates.
