Adults (18 years and older)
There is a lack of standard or well-established doses of arginine, and many different doses have been used and studied. A common dose is 2-3 grams taken by mouth three times daily. In studies, 0.5-16 grams of arginine has been taken daily by mouth for up to six months. Arginine has been applied to the skin in order to improve wound healing.
Doses of arginine used intravenously depend on specific institutional dosing guidelines and should be given under the supervision of a healthcare provider.
Children (younger than 18 years)
Arginine supplements are not recommended in children because there is not enough scientific information available and because of potential side effects.
Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
A severe allergic reaction, called anaphylaxis, has occurred after arginine injections. People with known allergies should avoid arginine. Signs of allergy may include rash, itching, or shortness of breath.
Side Effects and Warnings
Arginine has been well tolerated by most people in studies lasting for up to six months, although there is a possibility of serious side effects in some people.
Stomach discomfort, including nausea, stomach cramps, or an increased number of stools, may occur. People with asthma may experience a worsening of symptoms, which may be related to allergy, if arginine is inhaled.
Other potential side effects include low blood pressure and changes in numerous chemicals and electrolytes in the blood. Examples include high potassium, high chloride, low sodium, low phosphate, high blood urea nitrogen, and high creatinine levels. People with liver or kidney diseases may be especially sensitive to these complications and should avoid using arginine except under medical supervision. After injections of arginine, low back pain, flushing, headache, numbness, restless legs, venous irritation, and death of surrounding tissues have been reported.
