Complete Side Effects Guide and Safety Warnings
Dangerous Drug Interactions to Avoid
The most serious risk with Viagra involves combining it with nitrate medications. This includes GTN spray, isosorbide tablets, or any heart medication containing nitrates. This combination can cause a dangerous drop in blood pressure. If you take nitrates for chest pain, Viagra is not suitable for you. Always inform your prescriber about all medications you're taking, including over-the-counter remedies and supplements.
Common Side Effects You Should Expect
Most men experience mild side effects when starting Viagra treatment. Common reactions include headaches, facial flushing, indigestion, and nasal congestion. These effects typically occur within an hour of taking the tablet and usually subside within a few hours. Visual disturbances such as blue-tinted vision or increased light sensitivity can occur but are generally temporary.
When to Seek Immediate Medical Help
Certain side effects require urgent medical attention. If you experience chest pain during sexual activity, stop immediately and seek emergency help. A prolonged erection lasting more than four hours (priapism) requires immediate treatment to prevent permanent damage. Sudden vision or hearing loss, though rare, warrants immediate medical assessment.
Lifestyle Factors That Increase Side Effects
Alcohol can significantly increase your risk of side effects, particularly dizziness and low blood pressure. Large meals, especially those high in fat, can delay Viagra's effectiveness and may worsen digestive side effects. Grapefruit and grapefruit juice can interfere with how your body processes the medication, potentially increasing side effects.
Choosing Between Viagra and Sildenafil
Both branded Viagra and generic Sildenafil contain the same active ingredient and have identical side effect profiles. The choice often comes down to personal preference and cost considerations. EverydayMeds offers both options during checkout, allowing you to choose based on your individual needs and budget after consultation with our UK-licensed prescribers.
