Quick answer: Arginine and citrulline may lower blood pressure. Taken with blood pressure medicine, nitrates or ED pills such as sildenafil, Melonex could push pressure too low. Ask your doctor first, and do not use L-arginine after a recent heart attack.
Why it matters
Nitrates and ED pills work through the same nitric oxide pathway. Adding extra arginine or citrulline may increase the effect and cause dizziness or fainting.
Signs of low blood pressure
- Dizziness or light-headedness on standing
- Blurred vision
- Fatigue or nausea
- Fainting
The heart attack warning
A trial of L-arginine after heart attack was stopped early because of more deaths in the arginine group. MedlinePlus advises against it in that situation.
Questions for your doctor
- Is it safe with my current medicines?
- Which home readings should make me stop?
- Should I check my pressure more often at first?
