Viagra Dosage Instructions and Common Side Effects
Proper Viagra Dosage Guidelines
The standard 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 medication proves insufficient. It's crucial to never take more than one dose within 24 hours, regardless of the strength prescribed.
How to Take Viagra Effectively
Take your tablet with a glass of water on an empty stomach when possible. Fatty meals can significantly delay the medication's onset of action, potentially reducing effectiveness. The medication typically begins working within 30-60 minutes and effects may last up to 4-6 hours. Remember that sexual arousal is still necessary - Viagra enhances natural response rather than creating automatic erection.
Common Side Effects to Expect
Most men tolerate Viagra well, but some may experience mild side effects including headache, facial flushing, indigestion, or nasal congestion. These effects are usually temporary and diminish as your body adjusts. Dizziness can occur due to temporary blood pressure changes, so avoid driving immediately after taking the medication if affected.
Serious Side Effects Requiring Medical Attention
Seek immediate medical help if you experience chest pain, sudden vision or hearing loss, or an erection lasting longer than 4 hours (priapism). These rare but serious side effects require prompt treatment. Contact your prescriber if you develop severe headaches, significant dizziness, or any concerning symptoms that persist.
Safety Precautions and Contraindications
Never combine Viagra with nitrate medications (GTN spray, isosorbide) as this can cause dangerous blood pressure drops. Inform your prescriber about all current medications, especially blood pressure treatments, alpha-blockers, or other erectile dysfunction therapies.
