HoneyPezil Medication Interaction Checklist: What to Ask Your Pharmacist

By the HoneyPezil Insider editorial team · Updated · 2 min read

Quick answer: Arginine and citrulline relate to nitric oxide and can add to the effects of blood-pressure drugs, nitrates and erectile-dysfunction medicines, risking low blood pressure. Niacin can affect the liver and blood sugar, and some supplements affect bleeding. Show your pharmacist the label before starting.

Why interactions matter

HoneyPezil's amino acids feed nitric-oxide production, which relaxes blood vessels. Combined with drugs that also lower blood pressure, the effect can add up. A pharmacist can check your whole list in minutes.

The checklist

  1. Blood-pressure medicines: risk of low blood pressure and dizziness.
  2. Nitrates (nitroglycerin and similar): do not combine without medical approval.
  3. Erectile-dysfunction drugs (sildenafil-type): additive blood-pressure lowering.
  4. Blood thinners and antiplatelets: ask about bleeding risk.
  5. Diabetes medicines: niacin can affect blood sugar.
  6. Cholesterol medicines: niacin may interact; liver monitoring may be needed.
  7. Other supplements: niacin totals, nitric-oxide boosters and herbs.

How to talk to your pharmacist

Bring the bottle or a photo of the Supplement Facts panel and your medicine list. Ask: "Is there any interaction or reason to avoid this?"

Warning signs after starting

Light-headedness, fainting, a racing heart, chest pain, severe flushing or swelling need urgent care; see the NHLBI blood pressure page.

Documentation

Write down the date you started and any new symptoms in your journal. This helps your clinician.
