Viagra, or sildenafil, can cause side effects. Common ones include headache, flushing, nasal congestion, and indigestion. Less common, but still possible, are visual disturbances like blurred vision or sensitivity to light. Rarely, more serious side effects such as prolonged erection (priapism) occur; seek immediate medical attention if this happens.
Crucially, Viagra interacts with certain medications. Nitrates, often prescribed for chest pain, are a major concern. Combining them with Viagra can dangerously lower blood pressure. This combination may cause dizziness, fainting, or even a heart attack. Always inform your doctor about all medications you take, including over-the-counter drugs and supplements.
Alpha-blockers, used to treat high blood pressure and enlarged prostate, can also interact negatively with Viagra. This combination can lead to a significant drop in blood pressure. Your doctor should carefully monitor your blood pressure if you use both medications.
Specific medications to discuss with your doctor include: isosorbide dinitrate, nitroglycerin, amyl nitrate, and various alpha-blockers like tamsulosin (Flomax) and terazosin (Hytrin). This list is not exhaustive, so full disclosure is important.
Grapefruit juice also interacts with Viagra, potentially increasing its concentration in your bloodstream and raising the risk of side effects. Avoid grapefruit juice while using this medication.
Before taking Viagra, a thorough medical evaluation is necessary. Your doctor can assess your overall health and determine if Viagra is appropriate and safe for you, considering any existing conditions and medications you’re currently using.
