Can I take Quetiapine and Viagra connect together?

Why this happens

Both medicines can lower blood pressure. Quetiapine blocks certain receptors (alpha-1) that help control blood pressure, and Viagra (sildenafil) relaxes blood vessels. When used together, these effects add up. Additionally, both drugs can occasionally affect the electrical rhythm of the heart.

Use this combination with caution. If you feel dizzy or lightheaded, sit or lie down immediately. Always stand up slowly from a sitting or lying position. If you experience a painful erection or one that lasts longer than 4 hours, seek emergency medical help immediately. It is best to inform your GP that you are using both of these medications.
