Always read the product label carefully before use. Common side effects of some over-the-counter erectile dysfunction aids include headaches, flushing, nasal congestion, and upset stomach. These are usually mild and temporary. However, more serious, though rare, side effects can occur, including low blood pressure and vision changes. If you experience any unusual symptoms, stop use immediately and consult a doctor.
Interactions with Medications
Many OTC alternatives interact with certain medications. For example, some herbal remedies can interact with blood thinners, nitrates, and medications for high blood pressure. Always inform your doctor or pharmacist about all medications, supplements, and herbal remedies you are taking before starting a new product. This includes prescription drugs, over-the-counter medications, and dietary supplements.
Specific Product Considerations
The specific side effects and interactions vary depending on the active ingredients. Products containing L-arginine, for instance, may interact differently than those containing yohimbe. Check the product label and accompanying information for a complete list of potential side effects and drug interactions. If you have pre-existing health conditions, particularly heart problems, consult your physician before trying any OTC alternative to Viagra.
