Product Description:

Aivlosin® (Tylvalosin Tartrate) Water Soluble Granules is a water soluble granular powder for oral use by administration in the drinking water. Each gram of Aivlosin® Water Soluble Granules contains 0.625 grams of tylvalosin as tylvalosin tartrate.ANTIBIOTIC CLASSIFICATION:Tylvalosin, the active ingredient in Aivlosin® Water Soluble Granules, is a macrolide antibiotic.

Mixing Directions:

Aivlosin® Water Soluble Granules may be mixed directly into the drinking water system or first mixed as a stock solution in a smaller amount of water, which is then added to the drinking water system, for example, using an automatic water proportioner.

Direct Mixing:

When mixing the product directly into the drinking water system, the contents of the sachet should be sprinkled onto the surface of the water and mixed slowly and thoroughly for at least 3 minutes. Prepare a fresh batch of medicated drinking water daily.

Stock Solution:

When preparing a stock solution, the recommended concentration is one 40-gram sachet per US gallon, or one 160-g sachet per four (4) US gallons or one 400-gram sachet per 10 US gallons. Sprinkle sachet contents onto the surface of the water of the stock solution and mix slowly and thoroughly for at least 10 minutes. Use the stock solution for dilution into the drinking water system as soon as it is prepared. Add one (1) fluid ounce of this stock solution per 131 fluid ounces (1 US gallon, 3 fluid ounces) of drinking water to provide a final concentration of 50 ppm. If using an automatic water proportioner, set the flow rate to add stock solution at a rate of 1 fluid ounce per 131 fluid ounces of drinking water (1:131). Prepare a fresh batch of medicated stock solution daily.


WITHDRAWAL PERIOD:When used in accordance with label directions, no withdrawal period is required before slaughter for human consumption.

Residue Warning

ANTIBACTERIAL WARNINGS:Use of antibacterial drugs in the absence of a susceptible bacterial infection is unlikely to provide benefit to treated animals and may increase the development of drug-resistant pathogenic bacteria.

User Safety Warnings:

NOT FOR USE IN HUMANS.KEEP OUT OF REACH OF CHILDREN.May cause skin irritation. Tylvalosin Tartrate has been shown to cause hypersensitivity reactions in laboratory animals. People with known hypersensitivity to Tylvalosin Tartrate should avoid contact with this product. In case of accidental ingestion, seek medical advice.When handling Aivlosin® Water Soluble Granules and preparing medicated drinking water, avoid direct contact with the eyes and skin. Wear a dust mask, coveralls and impervious gloves when mixing and handling this product. Eye protection is recommended. In case of accidental eye exposure, wash eyes immediately with water. If irritation persists, seek medical attention. Avoid eating, chewing gum and smoking during handling. Wash contaminated skin.The Safety Data Sheet contains more detailed occupational safety information.To report adverse effects in users, to obtain more information or obtain a Safety Data Sheet, call Pharmgate Animal Health LLC. at 1-833-531-0114.


Not for use in lactating or pregnant females, or males and females intended for breeding. The effects of Tylvalosin on swine reproductive performance, pregnancy and lactation have not been determined. The safety and efficacy of this formulation in species other than swine have not been determined.To assure both food safety and responsible use in swine, concurrent use of tylvalosin in medicated drinking water and tylvalosin or another macrolide in medicated feed or by any other route of administration should be avoided. Tylvalosin belongs to the macrolide antimicrobial drug class. Macrolides are ranked as a critically important drug in human medicine; therefore, minimizing the risk of development of antimicrobial resistance to this class of drug is very important. The following conditions of use and restrictions listed below are critical forthe FDA’s strategy of risk management associated with tylvalosin:Always treat the fewest number of animals necessary to control a respiratory disease or PPE outbreak.Do not immediately follow this macrolide treatment with another macrolide treatment via any route.Prescriptions should not be renewed or refilled for animals already treated with one course of therapy with tylvalosin asdirected (See Dosage and Administration above).

Adverse Reactions In Animals:

No adverse reactions related to the drug were observed during clinical or target animal safety trials.

Clinical Pharmacology:

Tylvalosin is a 16-membered semi-synthetic macrolide antibiotic. Macrolides are generally considered to be bacteriostatic agents that exert their antibiotic effect by reversibly binding to the 23S rRNA of the 50S ribosomal subunit, thereby inhibiting bacterial protein synthesis. The spectrum of activity of most available macrolides used in veterinary medicine is primarily against Gram-positive bacteria and Mycoplasmas, with some activity against Gram-negative fastidious bacteria. These compounds have no activity against the naturally resistant Enterobacteriaceae including Escherichia coli and Salmonella spp. Typically, macrolides achieve higher concentrations in tissues than in plasma.

Control Of Porcine Proliferative Enteropathy (Ppe):

A multi-location challenge model study was conducted to confirm the effectiveness of AIVLOSIN® Water Soluble Granules for the control of PPE associated with Lawsonia intracellularis. Pigs were challenged by intragastric gavage with a mucosal homogenate containing a North American isolate of Lawsonia intracellularis isolated in 2005 that induces representative disease in challenged pigs. When at least 15% of the study pigs were showing signs of infection based on abnormal fecal scores, pigs were provided water containing tylvalosin at an inclusion rate of 50 ppm for five consecutive days, or were provided non-medicated water. Effectiveness was evaluated using clinical scores (pig demeanor score, abdominal appearance score, and fecal score) and clinically-validated gross PPE lesion scores. A conclusion of the effectiveness of 50 ppm tylvalosin for the control of PPE was determined based on a statistically significant (p = 0.0103) improvement in the clinically-validated gross PPE lesion scores in the 50 ppm tylvalosin-treated group compared to the non-medicated group.

Control Of Swine Respiratory Disease (Srd):

The effectiveness of Aivlosin® Water Soluble Granules for the control of swine respiratory disease (SRD) associated with Bordetella bronchiseptica, Haemophilus parasuis, Pasteurella multocida, Streptococcus suis and Mycoplasma hyopneumoniae was investigated in a natural field infection study conducted in the United States (three study sites) and Canada (one study site). Day 0 was defined when at least 15% of the candidate pigs were deemed clinically affected with SRD (moderate or severe respiratory score, moderate or severedepression score, and rectal temperature greater than or equal to 104.0 °F). On Day 0 a total of 980 pigs were enrolled and randomly assigned to a tylvalosin-treated group (50 ppm tylvalosin in drinking water for 5 consecutive days) or a non-medicated control group. Treatment success was evaluated on Day 7 and was defined as a pig with normal or mild respiratory score, normal or mild depression score, and rectal temperature less than 104.0 °F. The proportion of pigs meeting the definition of treatment success was numerically higher in the tylvalosin-treated group (48.5%) compared to the proportion of pigs meeting the definition of treatment success in the non-medicated control group (41.6%), and the observed difference was statistically significant (p=0.0353).Additional data to demonstrate the effectiveness of Aivlosin® Water Soluble Granules for the control of SRD associated with Mycoplasma hyopneumoniae was obtained in an experimentally-induced infection model study. Two hundred and forty (240) commercial crossbred pigs were challenged endotracheally with a representative isolate of M. hyopneumoniae. One hundred and ninety-two (192) study pigs were randomly assigned to either a tylvalosin-treated group (50 ppm tylvalosin in drinking water for 5 consecutive days) or a nonmedicated control group. Treatment was started when at least four of eight randomly pre-selected sentinel pigs exhibited a minimum of 3% weighted gross lung lesions consistent with M. hyopneumoniae infection. After a 5-day treatment period and a 5-day post-treatment period, study pigs were euthanized and necropsy performed to determine lung lesion scores. The analysis included 95 tylvalosin-treated pigs and 93 nonmedicated control pigs. There was a statistically significant (P<0.0001) improvement in pen mean M. hyopneumoniae lung lesion scores in the 50 ppm tylvalosin treated pigs (5.1%) compared to negative control (10.9%).
