Preparation and administration
Preparation for Application TachoSil comes ready to use in sterile packages and must be handled using sterile technique in aseptic conditions. Discard damaged packages as resterilization is not possible. When in the operating room, the outer aluminum foil pouch may be opened in a non-sterile environment (Fig. 1A) . The inner sterile blister must be opened in a sterile environment (Fig. 1B) .
Remove the TachoSil patch from the blister (Fig. 1C) , which can be used as a container for pre-moistening of the patch, if needed. Determine the size of patch(es) to be applied to the bleeding surface. Select the appropriate TachoSil patch so that it extends 1 to 2 cm beyond the margins of the wound. The patch can be cut to the correct size and shape if desired (Fig. 1D) .
If more than one patch is used, overlap patches by at least 1 cm. Prior to application, cleanse the area to be treated to remove disinfectants and other fluids. The fibrinogen and thrombin proteins can be denatured by alcohol, iodine or heavy metal ions. If any of these substances have been used to clean the wound area, thoroughly irrigate the area before the application of TachoSil.
Apply TachoSil directly to the bleeding area either wet or dry. If applied wet, pre-moisten TachoSil in 0.9% saline solution and then apply immediately. In the case of a wet tissue surface (e.g., oozing bleeding) TachoSil may be applied without pre-moistening.

Method of Application To ensure TachoSil adheres effectively, follow the recommended handling, preparation, and application procedures. Incorrect handling may result in non-adherence and reduced efficacy of TachoSil. Cleanse surgical instruments, gloves and adjacent tissues with saline solution to reduce the adherence to the TachoSil patch.
The white, inactive side of TachoSil may also adhere to surgical instruments (e.g., forceps), gloves or adjacent tissues covered with blood due to the affinity of collagen to blood. It is important to note that failure to adequately clean adjacent tissues may cause adhesions [see Warnings and Precautions ] . Apply the yellow, active side of the patch to the bleeding area (Fig. 2A) and hold in place with gentle pressure applied through moistened gloves or a moist pad for at least three minutes (Fig. 2B) .
To avoid pulling the patch loose, first place a clean surgical instrument at one end of the patch before relieving the pressure (Fig. 2C) . Gentle irrigation may also aid in removing the pre-moistened pad or gloved hand without removing TachoSil from the bleeding area. Leave TachoSil in place once it adheres to organ tissue.
Only remove unattached TachoSil patches (or part of) and replace with new patches. TachoSil cannot be resterilized once removed from inner pouch. Discard unused, opened packages of TachoSil at the end of the procedure.

Contraindications
Do not use TachoSil for: • Intravascular application. Bleeding from large defects in visible arteries or veins where the injured vascular wall requires repair and maintenance of vessel patency or where there would be persistent exposure of TachoSil to blood flow during absorption of the product. This can result in life-threatening thromboembolic events [see Warnings and Precautions (5.1) ] . • Individuals known to have anaphylactic or severe systemic reaction to human blood products or horse proteins [see Warnings and Precautions (5.2) ] . Do not apply TachoSil intravascularly. Intravascular application of TachoSil may result in life-threatening thromboembolic events.
( 4 ) Do not use TachoSil in individuals with known hypersensitivity to human blood products or horse proteins. ( 4 )

Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary A review of available data suggests that major birth defects occur in 2-4% of the U.S. general population and that miscarriage occurs in 15-20% of clinically recognized pregnancies, regardless of drug exposure. Animal reproduction studies have not been conducted with TachoSil. There are no adequate and well-controlled studies in pregnant women. It is also not known whether TachoSil can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. TachoSil should be administered to pregnant women only if clearly needed.
For breastfeeding, also see LactMed (National Library of Medicine), which summarizes milk levels and infant effects.

Not the price at the counterThese are not what a patient pays at the pharmacy counter. They are what pharmacies, health plans, and government buyers pay, before manufacturer rebates. A patient's cost depends on their insurance (copay, coinsurance, or deductible) or the pharmacy's cash price.
