OVERVIEW of ivermectin trials
Whether motivated by an abundance of caution, or for less scrupulous reasons, the National Institutes of Health (NIH) have, thus far, declined to give Ivermectin a full A-1 approval rating for use in preventing or treating COVID-19, instead upgrading their previously negative recommendation to now neither favoring nor disfavoring Ivermectin to combat COVID-19 outside of clinical trials. Consequently, few medical practices are willing to prescribe Ivermectin for use in preventing or treating COVID-19. However, Ivermectin is readily available for treating humans for parasites (by prescription), or for treating animals for parasites, with no prescription required.
As required by the food and Drug Administration (FDA), each package displays a label warning, "Not for use in humans." This is a label. Not a law.
Referring to Page 24, above, of the FLCCC paper titled "Review of the Emerging Evidence Demonstrating the Efficacy of Ivermectin in the Prophylaxis and Treatment of COVID-19," (linked above,) dosage recommendation to prevent COVID-19 in humans (see page 24), is 0.2 mg/kg body mass. This is equivalent to 0.091 mg/lb. The amount of paste required, which is diluted to only 1.87% Ivermectin, is 0.0049 g/lb body mass. If 1.87% Ivermectin deworming paste is used as the source of Ivermectin, the recommended dose would translate to 0.0049 gram of paste per pound of body weight, meaning, for example, that a 204 lb person's dose would be one gram.
PLEASE NOTE: This is for information purposes only, and does not constitute medical advice.
Durvet lists its 1.87% deworming paste as containing the following ingredients:
"Reproductive Toxicity: Suspected of damaging fertility or the unborn child. [NOTE: This is not of general concern for the elderly, who are no longer reproductively active, and who are most susceptible to death by COVID-19]. Specific Target Organ Toxicity (Single Exposure): Not classified. Specific Target Organ Toxicity (Repeated Exposure): May cause damage to organs through prolonged or repeated exposure. Aspiration Hazard: Not classified Symptoms/Injuries After Inhalation: Prolonged exposure may cause irritation. Symptoms/Injuries After Skin Contact: Prolonged exposure may cause skin irritation. Symptoms/Injuries After Eye Contact: May cause slight irritation to eyes. Symptoms/Injuries After Ingestion: This material is harmful orally and can cause adverse health effects or death in significant amounts. Chronic Symptoms: Suspected of damaging fertility or the unborn child. May cause damage to organs through prolonged or repeated exposure."
The following are my own calculations based on the Safety Data Sheet (SDS) and package labeling, and may be in error. Corrections are welcome. (Please send corrections to email@example.com.) The Safety Data Sheet identifies the ingredients of the Durvet paste as "acutely toxic" if ingested in doses exceeding:
Paste...............................................534.76 mg/kg body weight. ((0.2mg Ivermectin/kg body wt)/(1.87%) = 10.7 mg paste/COVID dose). (534.76mg/kg)/(10.7mg/kg) = 50 x FLCCC-recommended COVID dose. At 50 x suggested COVID dose, Ivermectin is considered "acutely toxic."
Proprietary Component A............>100 ml/kg. If Component A has density approximating that of water, one g/ml, concentrations greater than 100 g/kg body wt. are toxic. Since paste is 80.98% Component A, the amount of paste per kg body wt. containing a toxic level of Component A would be >100g/.81 = >123.5g. One tube of 1.87% Ivermectin contains 6.08 g of paste. The amount of paste containing an acutely toxic quantity of Component A per kg of body wt. is (123.5g/6.08g = 20.3 tubes of paste PER KILOGRAM OF BODY WEIGHT. A 200 lb (90.7kg) man must ingest 1,842 tubes of paste for its Component A to reach a concentration considered acutely toxic.
Proprietary Component B..........37,605 mg/kg. ((37.605g of Component B are found in 37.605g/7.65% = 491.6g paste, the amount found in 491.6g/6.08g/tube = 80.86 tubes of paste PER KILOGRAM OF BODY WEIGHT. A 200 lb (90.7kg)man must ingest 7,334 tubes of paste for its Component B to reach a concentration considered acutely toxic.
Proprietary Component C............3160 mg/kg. ((3160 mg of Component C are found in 3.16g/7.5% = 42.133g of paste PER KILOGRAM OF BODY WEIGHT. A 200 lb (90.7kg)man must ingest 3,821 tubes of paste for its Component C to reach a concentration considered acutely toxic.
Ivermectin...............................................10 mg/kg. (10/0.2 = 50 x suggested dose to combat COVID-19). A 200 lb (90.7kg) man must ingest 8 tubes of paste containing 6.08g each of 1.87% Ivermectin in order to reach acute toxicity.
For comparison, the Safety Data Sheet for sodium chloride https://isolab.ess.washington.edu/safety/sds/sodium_chloride.pdf lists acute toxicity for oral consumption of common table salt (NaCl) as 4 mg/kg for rats, and 8 mg/kg for rabbits. (For ethical reasons, acute toxicity dosage for humans for this and other substances IS NOT TESTED.)
If reasonable use of common table salt is safe for human consumption, how much more so is Ivermectin, including Durvet Ivermectin paste with all its listed components?
