Complete Side Effects Guide for Safe Usage
Common Side Effects of Viagra
Most men tolerate Viagra well, but common side effects may include headaches (affecting up to 16% of users), facial flushing, indigestion, and nasal congestion. These effects typically occur within 1-2 hours of taking the medication and usually resolve as the drug clears from your system. Dizziness and visual disturbances such as blue-tinged vision or increased light sensitivity may also occur. These common side effects are generally mild and temporary.
Serious Side Effects Requiring Medical Attention
Seek immediate medical help if you experience sudden vision loss in one or both eyes, sudden hearing decrease or hearing loss, chest pain, irregular heartbeat, or shortness of breath. Priapism (erections lasting more than 4 hours) requires emergency treatment to prevent permanent damage. Severe allergic reactions, though rare, may include rash, itching, swelling of face/tongue/throat, or difficulty breathing. Contact emergency services immediately if these occur.
Dangerous Drug Interactions
Never combine Viagra with nitrate medications (GTN spray, isosorbide) as this can cause a dangerous drop in blood pressure. Alpha-blockers for enlarged prostate may also interact, requiring dose adjustments. Inform your prescriber about all medications including blood pressure treatments, HIV protease inhibitors, antifungal medications, and antibiotics like erythromycin. EverydayMeds clinical assessments screen for these interactions before prescribing.
Who Should Avoid Viagra
Men with severe heart disease, recent heart attack or stroke (within 6 months), severe liver problems, or very low blood pressure should not use Viagra. Those taking nitrates or riociguat cannot safely use this medication. The clinical consultation process ensures only suitable candidates receive treatment.
Viagra vs Sildenafil: Same Side Effect Profile
Both branded Viagra and generic sildenafil contain the same active ingredient and have identical side effect profiles. EverydayMeds offers both options, allowing patients to choose between the branded or more cost-effective generic version based on their preference, with the same safety considerations applying to both.
