How Viagra Works and Why Headaches May Occur
Understanding Viagra's Mechanism of Action
Viagra contains sildenafil citrate, which belongs to a class of medicines called PDE5 inhibitors. When you become 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, allowing increased blood flow to continue. This enhanced circulation helps achieve and maintain an erection during sexual activity.
Why Headaches Occur with Viagra Treatment
The same mechanism that increases blood flow to the penis can also affect blood vessels throughout your body, including those in your head. This vasodilation (widening of blood vessels) may cause headaches in some patients. Studies indicate that approximately 16% of men taking sildenafil experience headaches, making it one of the most common side effects reported.
Managing Viagra-Related Headaches Effectively
If you experience headaches when taking Viagra, several strategies may help. Ensure you drink plenty of water before and after taking your dose, as dehydration can worsen headaches. Taking paracetamol according to package instructions is generally safe with Viagra, though you should consult your prescriber first. Avoid alcohol, which can increase the likelihood of headaches and reduce Viagra's effectiveness.
Treatment Options at EverydayMeds
EverydayMeds provides both branded Viagra and generic sildenafil following an online consultation with UK-licensed prescribers. Both contain the same active ingredient (sildenafil citrate) and work identically, with generic sildenafil offering a more cost-effective option. Available doses include 25mg, 50mg, and 100mg tablets. Your prescriber may recommend starting with a lower dose if you experience troublesome headaches, as side effects are often dose-related.
When to Seek Medical Advice
Whilst mild headaches are common and usually manageable, you should contact your prescriber if headaches are severe, persistent, or accompanied by vision changes. Your healthcare provider may adjust your dose or consider alternative treatments. Never exceed one dose in 24 hours, and always follow the prescribed dosing instructions provided with your medication.
