Why this happens
Both medicines work by widening your blood vessels to lower blood pressure or improve blood flow. When used together, their effects add up, which can lead to an excessive drop in blood pressure.
What you should do
Back to contentsUse this combination with caution. If you feel dizzy or lightheaded, sit or lie down until the feeling passes. When moving from a lying or sitting position, stand up slowly. If you experience chest pain, severe dizziness, or fainting, contact your doctor immediately. It is also best to avoid or strictly limit alcohol, as it can make these side effects worse.
