Side Effects
Side effects may include:
  • Cramps
  • Delayed Healing of Wounds (from topical application of aloe)
  • Gastrointestinal Upset
  • Intestinal Spasms
  • Rashes (from topical application of aloe)
  • Weakness
Precautions and Adverse Events:
  • Avoid or contact a licensed healthcare practitioner, if you have intestinal/bowel obstruction, fecal impaction, inflammatory bowel diseases (such as Crohn’s disease, ulcerative colitis), acute abdomen, appendicitis, abdomen pains of unknown reason, liver, kidney, heart, and other gastrointestinal problems, allergies to plants in the order Asparagales (asparagus, onions, etc.).
  • You should not ingest aloe latex, and use caution if you take products containing the outer part of the aloe leaf, since these products may contain some aloe latex. The FDA in 2002 required that all aloe laxative products should be removed from stores or reformulated because manufacturers did not provide the necessary safety information.
  • Consumption of large doses and long-term use of aloe may cause body salt imbalances, severe stomach discomfort, dehydration, reddish urine, bloody diarrhea, kidney damage or failure, edema, accelerated bone deterioration, blood build-up in the pelvis, irregular heartbeat, weak muscles, severe diarrhea (aloe is a strong laxative), albuminuria, melanosis coli (usually a reversible condition after discontinued use of aloe), severe weight loss.
  • Consumption of aloe has caused a few cases of liver inflammation (hepatitis); these incidences may have been due to long-term use of aloe and hypersensitive allergic responses to aloe.
  • Use caution and monitor your blood sugar levels, if you are taking aloe and have diabetes. If you have low blood sugar symptoms, contact a licensed healthcare practitioner.
  • Children younger than 12 years of age should not ingest aloe because of its strong laxative properties or, in other cases, it may instead cause constipation.
  • There are reports of serious adverse events (and possibly death) from aloe injections, aloe overdose, and ingestion of aloe latex.
  • After applying aloe to areas of skin treated by dermabrasion and chemical peel, patients had severe dermatitis.
  • Long-term use of topical and oral products containing aloe may cause minor to severe allergic skin reactions.
  • Especially avoid aloe latex if you have hemorrhoids; it may worsen the condition.
  • Aloe can cause contact dermatitis.
[57-71]


Pregnant or Nursing

Do not use aloe if you are or may be pregnant. There are concerns that aloe can cause miscarriage, premature births, or congenital malformations. Though, there is not enough research on the use of supplements containing aloe during pregnancy and breast-feeding, you should consult a licensed healthcare practitioner. [57-71]



Interactions

Major

  • Avoid aloe use at least 2 weeks before surgery; it may interact with anesthetics
  • Digoxin; aloe appears to interact with digoxin and can cause hypokalemia
  • Drugs that may cause potassium loss (Hypokalemia Drugs)
  • Drugs to Treat Irregular Heartbeats
  • Furosemide
  • Hydrochlorothiazide
  • Sevoflurane, an anesthetic
  • Thiazide Drugs
[72-77]

Moderate
