Consult your doctor before starting any medication, including sildenafil, vardenafil, or tadalafil. These medications can interact with other drugs, so provide a complete medication history.
Common Side Effects
Headache is a frequent side effect, often mild and transient. Facial flushing (redness) also occurs commonly. Nasal congestion and Dyspepsia (indigestion) are other reported side effects. These usually subside within a few hours. Rarely, you might experience Dizziness or Visual disturbances, such as blurred vision or changes in color perception. Report any persistent or worsening symptoms to your physician immediately.
Serious Side Effects: Seek Immediate Medical Attention
While rare, some serious side effects require urgent medical attention. Prolonged erection (priapism) is a medical emergency and needs immediate treatment to prevent permanent damage. Sudden vision loss or Hearing loss also warrant immediate medical evaluation. Similarly, Chest pain or Irregular heartbeat require prompt medical attention, as these could indicate serious cardiovascular problems. These are serious potential risks and need immediate action.
Specific Considerations
Heart conditions: These medications can affect blood pressure, so individuals with heart problems should discuss their use with their cardiologist. Liver and kidney disease can influence how these drugs are processed in the body, potentially increasing the risk of side effects. Patients taking nitrates should absolutely avoid these medications due to the risk of dangerously low blood pressure.
Medication Interactions
Alpha-blockers (often used for prostate problems) can interact with these drugs, leading to a significant drop in blood pressure. Other medications that affect the liver’s ability to metabolize the drugs may increase the risk of side effects. Always inform your doctor of all medications you are currently taking, including over-the-counter drugs and herbal supplements. This is paramount for safe usage.
