Kamagra Australia, containing sildenafil citrate, can interact with other medications, potentially causing adverse effects. It should not be taken with nitrates, often prescribed for chest pain, as this combination can lead to a dangerous drop in blood pressure. Additionally, combining Kamagra with certain blood pressure medications, and HIV protease inhibitors may also cause harmful interactions. It's crucial to inform your healthcare provider about all medications and supplements you're taking before using Kamagra. Always follow medical advice to ensure safe use and avoid potential risks associated with drug interactions.
