Proper Dosage and Administration Instructions
Standard Dosing Guidelines
The recommended starting dose for Viagra is 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 the lower dose proves insufficient. Never exceed one tablet in 24 hours, regardless of strength.
Timing and Food Considerations
Viagra should be taken 30-60 minutes before anticipated sexual activity. Taking it on an empty stomach may improve effectiveness, as fatty meals can delay absorption and reduce the medication's impact. The effects typically last 4-6 hours, though this doesn't mean you'll maintain an erection for this duration.
Common Side Effects to Expect
Most men tolerate Viagra well, but some may experience mild side effects. The most frequently reported include headaches (affecting up to 16% of users), facial flushing, nasal congestion, and indigestion. These effects are usually temporary and resolve within a few hours as the medication clears your system.
Serious Side Effects Requiring Medical Attention
Whilst rare, some side effects require immediate medical intervention. Priapism (erection lasting over 4 hours) affects fewer than 1 in 1,000 men but requires emergency treatment to prevent permanent damage. Sudden vision or hearing loss, though extremely uncommon, warrants immediate medical consultation.
Managing Minor Side Effects
If you experience headaches, staying hydrated and taking paracetamol may help. For nasal congestion, avoid decongestant medications and allow symptoms to resolve naturally. Should side effects persist or worsen, consult your prescriber about adjusting your dose or exploring alternative treatments.
Drug Interactions and Safety Precautions
Never combine Viagra with nitrate medications (such as GTN spray) as this can cause dangerous blood pressure drops. Inform your prescriber about all medications, particularly alpha-blockers, blood pressure medications, and HIV treatments. Excessive alcohol consumption may increase side effect risk and reduce effectiveness.
