Always read the product label carefully. Common side effects include headache, flushing, nasal congestion, and upset stomach. These are usually mild and temporary.
More serious, though rare, side effects can include changes in vision, hearing loss, or prolonged erection (priapism). Seek immediate medical attention if you experience any of these.
OTC ED medications can interact with certain drugs. Nitrates, often prescribed for heart conditions, are a particularly dangerous combination, potentially causing a significant drop in blood pressure. Discuss all medications, including supplements, with your doctor before using an OTC ED medication.
Alcohol can intensify side effects. Limit or avoid alcohol consumption while taking these medications.
Certain pre-existing health conditions, like heart disease or high blood pressure, may increase your risk of experiencing side effects. Consult your physician before use if you have any underlying health issues.
If side effects are bothersome or persist, stop using the medication and contact your doctor or pharmacist for advice. They can help assess the situation and offer alternative solutions.
