Pyrantel (dewormer, will NOT treat tapeworms)
Pyrantel (dewormer, will NOT treat tapeworms)
Sold on Amazon as “Pyrantel 50mg 16oz”
Can be given directly to your pet or mixed with food. Shake bottle before each use, this is extremely important because this is a suspension and the active ingredient will settle at the bottom of the bottle. For puppies: Administer at 2, 3, 4, 6, 8, and 10 weeks of age. Treat mother at the same time. For adults: First initial worming: give one dose followed by another dose 2 weeks later. Thereafter, give one monthly dose.
DOSAGE FOR DOGS: Measuring with an oral medication syringe, Give 1/10 (one tenth) of 1 cc for each 2 lbs of body weight or 0.05 cc per pound
*One teaspoon (5 cc or 5 ml) for a 100 lb dog
*One half of a teaspoon for a 50 lb dog
*One fourth of a teaspoon for a 25 lb dog
*One eighth of a teaspoon for a 12 lb dog
NOTE: If worms are resistant, the above dosage can be doubled. The dosing information listed above is for 2.5 mg of Pyrantel Pamoate per pound (this Pyrantel Pamoate suspension is 50 mg to 1 mL (1 mL = 1 cc) so 1 cc will treat 20 lbs, 5 cc’s will treat 100 lbs, and every 1/10 of 1 cc will treat 2 lbs). Pyrantel Pamoate is usually administered at either 2.5 mg per pound, or, in cases where worms are resistant, 5 mg per pound.
OVERDOSAGE: Pyrantel Pamoate has a moderate margin of safety. Doses approximately 7 times the recommended 2.5 mg per pound generally have not resulted in toxic reactions. Signs of an overdose could include panting, staggering, or loss of balance. Contact a veterinarian immediately should you notice any of these signs or in cases of accidental overdose.
SHELF LIFE – This product has a shelf life of 3 years stored at controlled room temperature. I wouldn’t give it after the expiration date on the bottle as it would be less effective, although not harmful, because according to a Material Safety Data Sheet for Pyrantel Pamoate, products of degradation are less toxic than the product itself.
2 week followup dose to catch any hatched eggs and then once a month thereafter to keep them worm free.
Pyrantel (dewormer, will NOT treat tapeworms)
Sold on Amazon as “Durvet Pyrantel Paste Wormer, 23.6gm”
This product is more concentrated than liquid pyrantel suspension “Pyrantel 50mg 16oz” (you will have to give your dog a large quantity, making administration harder) if you use the liquid, and it can also be hard to administer since it is unflavored.
The proper dosage in dogs for pyrantal is 2.5 milligrams (mg) per pound. Double if your dog’s worms are resisting treatment. Per the packaging, this product contains 171 mg/ml pyrantel. Here is a sample calculation for my puppy, who weighs 35 lbs.
35 lbs x 2.5 mg/lb x 1 ml/171 mg = ~ .5 ml of this product (or double for resistant worms).
In simpler terms, your dog needs .015 ml per pound (ie multiply your dogs weight by .015 to get the dosage in mls). If your dog or puppy is very small (less than 10 lbs) it will be too hard to measure; in this case, purchase the more dilute liquid, or the tablets if you don’t mind the higher price tag. Before measuring squeeze the product out of the tube into a glass, airtight container for storage label with expiration, dosage, and contents and store in a cool dark place at room temp. I measure with 1 cc syringe. Measure -slowly- to avoid sucking up air bubbles (which will lower your volume and thus the dose). Be sure to wash the syringe after each use.
Paste Dosage table (.015 ml per pound):
25 to 36 pounds: 0.54 ml
37 to 48 pounds: 0.72 cc
49 to 60 pounds: 0.90 cc
62 to 72 pounds: 1.08 cc
73 to 84 pounds: 1.26 cc
85 to 97 pounds: 1.47 cc
98 to 109 pounds: 1.63 cc
110 to 121 pounds: 1.83 cc
Fenbendazole (dewormer WILL treat: giardia, roundworms, hookworms, whipworms)
Fenbendazole Paste 10% (dewormer)
Sold on Amazon as “Safeguard Horse Dewormer – 25 Gm”
2cc paste per 10 lbs of dog weight
The way I measure it is take a medical syringe (without the needle) and hold it pressed against the large dewormer syringe. Press on the dewormer syringe plunger until you get the correct dose in the medical syringe.
Fenbendazole 10% (100 mg/mL) (dewormer)
Sold on Amazon as “Durvet Safeguard Goat Dewormer, 125ml”
Shake bottle well and then measuring with an oral medication syringe give 1 mL (equal to 1 cc or ¼ teaspoon) per each 5 lbs. of your dog’s weight mixed with a small amount of moist dog food (to make sure the dog consumes it all). Repeat this dose for three days in a row. If worms where found (not given as preventative), repeat again in 2 weeks.
IN DOGS fenbendazole targets: Roundworms (Toxocara canis, Toxascaris leonina), Hookworms (Ancylostoma caninum, Uncinaria stenocephala), Whipworms (Trichuris vulpis), and Tapeworms (Taenia pisiformis) as well as being effective against giardia.
Fenbendazole is very safe. Doses up to 100 times the recommended dose are tolerated without serious side effects.
Ivermectin for heartworm prevention
Ivermectin Paste 1.87% (for heartworm prevention)
Sold on Amazon as “Ivermectin Paste Dewormer – 6.08g dose @ 1.87% Apple Flavorl”
The recommended Ivermectin dosage for dogs is 2.72 mcg/lb, which is what you’ll find in the name brand medications like Heartgard. 1.87% Ivermectin= 1.87 gram/100 ml= 18.7 mg/ml= 18,700 mcg/ml. Let’s create solution that contains 1,000 mcg/ml; this concentration is easy to work with for large dogs- you will need to dilute it more if you have a small dog less than 20 lbs in order to be able to measure accurately.
I used 60 ml distilled water which I will add the Ivermectin to for the dilution. Note that 1% Ivermectin cannot be diluted with water, however, this paste is water soluble. This volume of water is easily measured with 3 ml blunt tip syringes with needles, which I also purchased here on Amazon ($9 for 10). I will need to add 3.4 ml of the paste to my 60 ml water. Measure the paste with a 1 ml syringe -very- slowly to avoid sucking up bubbles, which decrease your dosage. You can also buy these syringes cheaply on Amazon. The paste is too thick to measure with a needle, and I found the 3 ml syringe more challenging. Quick math check: 3.4 ml x 18,700 mcg/ml= 63,580 mcg Ivermectin. 63,580 mcg/63.4 ml= ~1000 mcg/ml. When you add this paste to the water it will turn milky; store in a glass container at room temp in a dark place (per label instructions); label with expiration date (found on box) and dosage so you won’t forget! Be sure to shake well before measuring as it will settle when stored.
With this dilution, the dosage would be .0272 ml per 10 lbs of dog; you can safely double that for extra protection, but I wouldn’t do more than that. For my dog I can measure this amount with a 1 ml syringe and dab it on some bread for her to eat. If your dog is picky you can take the needle off the 3 ml syringe and put it on the 1 ml and inject the solution into a piece of hot dog to more easily mask the taste. Also remember that Ivermectin is not safe for use on Collies, Collie mixes, and other herding breeds. This diluted solution has enough Ivermectin to treat 23,000 POUNDS of dog! Now do you see how horrifying it is to use a full or even half click of raw paste? And we didn’t even use the full tube 🙂
Ivermectin 1% (for heartworm prevention)
Sold on Amazon as “Ivermectin 1% [Noromectin] Injection For Cattle & Swine, 50 ml”
Dilute the ivermectin with food-grade (USP) glycerin or propylene glycol (liquid ivermectin injectable solutions are made with 40% glycerol and 60% propylene glycol, so we know that ivermectin mixes well with those ingredients.
Directions for making 30:1 dilution of 1% solution
A 30:1 dilution works best for smaller dogs. Ivemectin is given orally (never use pour-on solutions for heartworm prevention).
Mix 30 parts glycerin, propylene glycol, or vegetable oil to 1 part ivermectin 1% solution. Shake well before using to mix the ivermectin evenly. Refrigerate any unused portion (do not store mixtures with vegetable oil).
Dosage using Ivermectin 1% solution at 30:1 dilution for heartworm prevention (you may want to double these doses for better protection):
< 6 pounds: 0.05 cc (one-half of 0.1 cc, or 1 drop) 6 to 12 pounds: 0.1 cc 13 to 24 pounds: 0.2 cc 25 to 36 pounds: 0.3 cc 37 to 48 pounds: 0.4 cc 49 to 60 pounds: 0.5 cc 62 to 72 pounds: 0.6 cc 73 to 84 pounds: 0.7 cc 85 to 97 pounds: 0.8 cc 98 to 109 pounds: 0.9 cc 110 to 121 pounds: 1 cc To make a small amount of the mixture, you will need a 1 cc syringe that measures accurately to the tenth of a cc. Draw up 0.1 cc of Ivermectin solution in a 1 cc syringe, and mix well with 3 cc of glycerin, propylene glycol, or vegetable oil, giving you 3 ccs at a dilution ratio of 30:1. This is enough to treat 300 pounds of dogs using the 1% solution. To make larger amounts of the mixture, use a 1 fluid ounce dropper bottle, which is 30 ml. Put 1 ml of ivermectin solution in a 1 fluid ounce dropper bottle, then fill with glycerin, propylene glycol, or vegetable oil. This will be enough to treat 3,000 pounds of dogs (e.g., 300 10-lb dogs or 150 20-lb dogs) using the 1% solution. 1 cc of ivermectin 1% diluted 30:1 contains 333 mcg; 0.1 cc = 33 mcg. The exact dosage is 0.0824 cc (approximately 0.1 cc) per 10 pounds of body weight. Directions for making 9:1 dilution of 1% solution To make a small amount of the mixture, you will need a 1 cc syringe that measures accurately to the tenth of a cc or a dropper bottle. Draw up 0.1 cc of Ivermectin solution in a 1 cc syringe, and mix well with 0.9 cc of glycerin, propylene glycol, or vegetable oil, giving you 1 cc at a dilution ratio of 9:1. This is enough to treat 333 pounds of dogs using the 1% solution. Dosage using Ivermectin 1% solution at 9:1 dilution for heartworm prevention. up to 18 pounds: 0.05 cc (one-half of 0.1 cc, or 1 drop) 19 to 36 pounds: 0.1 cc 37 to 73 pounds: 0.2 cc 74 to 110 pounds: 0.3 cc 111 to 147 pounds: 0.4 cc Other Dilute Ivomec (you want the 1% injectable Ivomec for cattle) one part Ivomec to 9 parts propylene glycol....then give the dog 1/10 of a cc per 10 lbs. of dog of this solution (a 40 lb. dog gets 4/10 of a cc.) Simply add 0.3 ml’s of 1% Ivermectin injectable to one ounce of propylene glycol, making a 100 microgram/ml solution. Dose this at 0.1 ml per pound of body weight (10 micrograms per pound) once monthly."
