WARNING Important Safety Information (See full prescribing information for complete boxed warning.)
Intended for use only by licensed health care provider experienced in administering allergenic extracts and trained to provide immediate emergency treatment in the event of a life-threatening reaction. Observe patients for at least 30 minutes following administration. Immunotherapy may not be suitable for patients with medical conditions that reduce their ability to withstand a systemic reaction. Allergenic extracts can cause serious systemic reactions, including anaphylactic shock and in rare cases death, especially in patients who have severe or steroiddependent asthma, cardiovascular disease, or in patients who use beta blockers. Do not inject intravenously. This product is intended for subcutaneous injection for immunotherapy and percutaneous use for diagnosis. Refer to contraindications, warnings, precautions, adverse reaction and over dosage for more detailed information.
Why Choose Our Ultrafiltered Dog Hair & Dander Extract?
Identify More Allergic Patients
When choosing an extract for skin prick testing, the Diagnostic Practice Parameter recommends using the highest concentration available.2,3 Recent studies suggest UF Dog produces more skin test positive reactions with a higher sensitivity for detecting more allergic patients than other dog extracts.4
Target an Optimal Dose: UF Dog’s higher concentration achieves the Immunotherapy Practice Parameter target maintenance dose of 15ug of Can f1.4
Formulation Flexibility: Preparing formulations with UF Dog offers specific advantages for your practice and your patients.
- Achieve an optimal dose with a typical injection volume2
- Avoid higher glycerin concentrations, which can be painful upon injection5
- Combine allergens into fewer vials so patients require fewer injections per visit
Switching is Simple
- Identify patients who tolerate their injections well and those with a complicated health history.
2. Determine an appropriate dose adjustment to account for potency difference and patient’s prior response to treatment.
3. Advance the patient to their target maintenance dose and monitor for tolerance.
