What is Defencath?
From the FDA label:DEFENCATH (taurolidine and heparin) CLS contains taurolidine, a thiadiazinane antimicrobial, and heparin sodium, an anti-coagulant. Taurolidine Taurolidine is an antimicrobial agent derived from the naturally occurring amino acid taurine. The chemical name is 4,4'-methylenebis(1,2,4-thiadiazinane)-1,1,1',1'-tetraoxide. The molecular weight is 284.36, and the molecular formula is C 7 H 16 N 4 O 4 S 2 . The structural formula of taurolidine is: Heparin Sodium Heparin is an anticoagulant consisting of heterogeneous group of straight-chain anionic mucopolysaccharides, called glycosaminoglycans. It is composed of polymers of alternating derivatives of α-D-glucosamido ( N -sulfated, O -sulfated, or N -acetylated) and O -sulfated uronic acid (α-L-iduronic acid or β-D-glucuronic acid). Heparin is derived from porcine intestinal mucosa. The structure of heparin sodium (representative subunits) is: DEFENCATH is for central venous catheter instillation use. DEFENCATH CLS is available as a sterile, non-pyrogenic, preservative-free, clear, aqueous-based solution of taurolidine and heparin with a pH of 5.5-6.5 in the following strengths: 3 mL of catheter lock solution in a single-dose vial containing taurolidine 40.5 mg/3 mL (13.5 mg/mL), and heparin 3,000 USP Units/3 mL (1,000 USP Units/mL) 5 mL of catheter lock solution in a single-dose vial containing taurolidine 67.5 mg/5 mL (13.5…
How to use
DEFENCATH is for instillation into CVCs only [see Indications and Usage (1) ]. DEFENCATH is not intended for systemic administration. Do not use DEFENCATH as a catheter lock flush product. Withdraw a sufficient volume of DEFENCATH catheter lock solution (CLS) from the vial using a sterile needle and syringe to fill the catheter lumens. Use 3 mL or 5 mL single-dose vial (depending on the volume of the catheter lumens) to instill DEFENCATH into each catheter lumen at the conclusion of each HD session for patients with kidney failure requiring chronic HD. Prior to initiation of the next HD session, DEFENCATH should be aspirated from the catheter and discarded. If DEFENCATH cannot be aspirated, continue with standard of care CVC preparation and flush with normal saline. If a catheter malfunction is suspected, appropriate standard of care measures should be instituted. Each DEFENCATH single-dose vial is designed for use with a single patient as a single instillation in the CVC. Discard any unused portion of DEFENCATH remaining in the vial. DEFENCATH is for instillation into CVCs only. ( 2 ) DEFENCATH is not intended for systemic administration. ( 2 ) Do not use DEFENCATH as a catheter lock flush product.

Side effects
The following clinically significant adverse reactions are described elsewhere in the labeling: Heparin-Induced Thrombocytopenia [see Warnings and Precautions (5.1) ] Drug Hypersensitivity [see Warnings and Precautions (5.2) ] The most frequently reported adverse reactions occurring in greater than or equal to 2% of patients in Trial 1 using DEFENCATH as a CLS were hemodialysis catheter malfunction, hemorrhage/bleeding, nausea, vomiting, dizziness, musculoskeletal chest pain, and thrombocytopenia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact CorMedix Inc at 1-844-424-6345 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Overview of the Safety Evaluation of DEFENCATH The safety of DEFENCATH was evaluated in a single, active-controlled, double-blind, randomized Phase 3 trial, LOCK-IT-100 (referred to as Trial 1), in adult patients with kidney failure receiving chronic HD through a CVC. In Trial 1, the safety population was comprised of 797 patients with 398 patients using DEFENCATH as a CLS and 399 using heparin as a CLS. Patients used DEFENCATH as a CLS for a mean duration of…
Warnings
Important safety information
Heparin-Induced Thrombocytopenia (HIT) : HIT was reported in Trial 1 at an incidence rate of 0.3% in patients using heparin, a component of DEFENCATH as a CLS. If HIT occurs, discontinue DEFENCATH and institute appropriate supportive measures.

If a hypersensitivity reaction occurs, discontinue DEFENCATH and institute appropriate supportive measures. ( 5.2 ) 5.1 Heparin-Induced Thrombocytopenia Heparin-induced thrombocytopenia (HIT) was reported at an incidence rate of 0.3% in Trial 1 in patients using heparin, a component of DEFENCATH, as a CLS. If HIT occurs, discontinue DEFENCATH and institute appropriate supportive measures [see Contraindications (4) ] . 5.2 Drug Hypersensitivity Drug hypersensitivity reactions were reported at an incidence rate of 0.5% in Trial 1 in patients using heparin, a component of DEFENCATH, as a CLS.

Frequently asked questions
- How much does Defencath cost?
- Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $2.24 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.

- pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Defencath.

Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
