Consult your doctor before starting any erectile dysfunction medication. A thorough medical history and physical exam are crucial for determining the appropriate treatment and identifying potential risks.
Follow your doctor’s prescribed dosage precisely. Never exceed the recommended amount, as this can increase the risk of side effects.
Be aware of potential side effects. Common side effects include headaches, facial flushing, nasal congestion, and indigestion. More serious, though rare, side effects may include vision changes or hearing loss. Report any concerning side effects to your physician immediately.
Avoid alcohol and grapefruit while taking these medications. These substances can interact negatively with erectile dysfunction drugs and either increase side effects or reduce effectiveness.
Certain medications can interact with erectile dysfunction drugs. Provide your doctor with a complete list of all medications, supplements, and herbal remedies you are currently taking.
| Nitrates | Can cause dangerously low blood pressure |
| Alpha-blockers | May increase the risk of low blood pressure |
| CYP3A4 inhibitors | Can increase the concentration of erectile dysfunction medication in the blood |
Store medications properly, following the instructions on the label. Keep them out of reach of children and pets.
Don’t use erectile dysfunction medications if you have certain heart conditions or have experienced a recent heart attack or stroke. Your doctor will assess your suitability for these medications.
Regular exercise, a healthy diet, and managing stress can positively impact erectile function. Lifestyle changes can often complement medication treatment.
