Arginine Injection

• You want to confirm arginine injection’s approved indications
• You have low blood pressure or a history of heart disease and want to know whether it is safe
• You have asthma or kidney disease and want to discuss it in advance

If fatigue persists, checking causes such as anemia, thyroid problems or sleep comes first.

• 01

  Where you are now, and where we start

  Arginine injection’s approved indications, and low-blood-pressure and cardiovascular contraindications

• 02

  The change you want, the impression you keep

  We check for low blood pressure, a history of heart attack or severe acidosis — these are contraindications in the label.

• 03

  How it differs from similar options

  Energy and fatigue relief are not approved indications. Tell us exactly what you hope for, and we will explain the evidence.

• 04

  Health information and recovery schedule

  The label calls for blood-pressure monitoring during and for 24 hours after administration, so we explain what to watch for once you are home.

Arginine injection is approved for treating hyperammonemia and for diagnostic testing.

In the MFDS drug database (nedrug), L-arginine hydrochloride injection is approved to lower blood ammonia during acute worsening of hyperammonemia caused by congenital urea cycle disorders and lysinuric protein intolerance. The 60% concentrate product is also approved as an acidifying agent for severe metabolic alkalosis and for pituitary function tests that measure growth hormone release. The label notes that low blood pressure can occur because it stimulates nitric oxide production.

How it works

• 01

  Ingredient

  The active ingredient is L-arginine hydrochloride. It goes by its ingredient name rather than a nickname.

• 02

  Approved indications

  Lowering blood ammonia during acute worsening of hyperammonemia caused by congenital urea cycle disorders and similar conditions. Some products are also approved for pituitary function testing.

• 03

  Blood pressure

  Because it stimulates nitric oxide production, blood pressure can drop; the label calls for blood-pressure monitoring during and for 24 hours after administration.

• 04

  Leakage outside the vein

  Skin necrosis and ulcers have been reported when it leaks outside the vein, so the infusion is to be stopped immediately if the injection site turns red or swells.

1. 01

   Contraindication check

   We check for low blood pressure, a history of heart attack, severe acidosis, conditions linked to nitric oxide production, and allergic tendency.

2. 02

   Who needs extra caution

   We check for liver or kidney disease, electrolyte imbalance and bronchial asthma.

3. 03

   Infusion and monitoring

   We give it slowly, watching the injection site and for blood-pressure-related symptoms, and explain what to watch for after you go home.

What the procedure is like

• On the day, don’t get up suddenly — move slowly.
• If you feel very dizzy, avoid driving.
• If the injection site swells or hurts, don’t rub it — contact the clinic.

Safety & considerations

Arginine injection is not a medicine approved for energy or fatigue relief. If you have low blood pressure or a history of heart disease, be sure to tell us in advance. Individual responses vary.

1. During infusion

   Speed-related reactions

   Rapid administration can cause nausea, vomiting, redness, headache, numbness and vein irritation.

2. During and right after

   Injection site

   Tell us at once if the injection site turns red, swells or hardens — this may be a sign of leakage outside the vein.

3. 24 hours

   Low blood pressure

   The label calls for blood-pressure monitoring during this period. If you feel very dizzy, lie down and contact the clinic.

Based on Korean-approved products with the same ingredient.

• Q. What is arginine injection originally used to treat?

  In Korea it is approved to lower blood ammonia when hyperammonemia suddenly worsens due to conditions such as congenital urea cycle disorders. Some products are also used in pituitary function tests that measure growth hormone release. Boosting energy or relieving fatigue is not among its approved indications.

• Q. My blood pressure tends to be low — can I have arginine injection?

  It is contraindicated in people with low blood pressure according to the label. This is because stimulating nitric oxide production can lower blood pressure. If your blood pressure is usually low, please be sure to tell us.

• Q. What should I be careful about in the day after arginine injection?

  The label calls for blood-pressure monitoring during and for 24 hours after administration, in case blood pressure drops. On the day, avoid getting up suddenly and move slowly. If you feel dizzy, sit or lie down, and avoid driving. If the dizziness is severe, stay lying down and contact the clinic.

• Q. Is it the same as arginine supplements?

  The ingredient name is the same, but the injection is a prescription-only medicine with its own approved indications and contraindications. If you take supplements, please tell us about them too. In particular, the label states that the injection must not be given to people with a history of heart attack or with severe acidosis.

• Q. The arginine injection site has become swollen and red.

  Redness and swelling at the injection site can be a sign that the solution has leaked outside the vein. If it leaks outside the vein, skin necrosis or ulcers can develop, so the label says to stop the infusion immediately when these signs appear. Don’t rub it — contact the clinic straight away.
