Sterile Water for Injection, USP is distilled water that has been sterilized and is nonpyrogenic. It is packaged in a single-dose bottle and is intended for intravenous administration once an appropriate solute has been added. It is also possible to utilize it as a container for dispensing diluent, if desired.
What is SWFI diluent?
DESCRIPTION. Sterile Water for Injection, USP is a preparation of distilled water for injection that is guaranteed to be sterile, nonpyrogenic, and devoid of any solutes. Only as a sterile solvent, diluent vehicle, or carrier for solutions or medications that are appropriate for parenteral administration can it be used.
What is sterile water injection used for?
Before we begin – Commercially available sterile water (SW) for injection vials can be purchased in volumes ranging from 5 mL all the way up to 100 mL. The vast majority of these presentations, if not all of them, are currently on back order, and the estimated date of their resupply ranges from the end of January to the beginning of March 2018.
Because there is a shortage of SW for injection vials, the demand for SW for injection bags ranging in size from 250 mL to 3,000 mL has grown. In addition to that, there have been sporadic shortages of these goods in their bigger sizes. Pfizer and Fresenius Kabi are the two largest manufacturers of SW for injectable vials at the moment in the pharmaceutical industry.
As a result of manufacturing delays, Pfizer’s output has been significantly reduced. Fresenius Kabi has not stated a cause for the shortfall; nonetheless, it is customary that other producers are unable to match the market demand when one manufacturer manufactures less than the usual amount of a product.
Vials of sterile water for injection are most commonly used for the purpose of reconstituting drugs that are only accessible in powder form. Although the prescribing advice for some drugs may suggest other sterile liquids that can be used for reconstitution, the majority of pharmaceuticals require that sterile water for injection be used.
In the absence of a reliable supply of SW for injection, medical professionals are forced to choose between utilizing other treatment modalities or utilizing a sterile liquid for injection in place of SW, despite the fact that they do not have definitive information regarding the effects that this will have on the drug’s stability and compatibility.
- If prescription vials are reconstituted with a sterile liquid that is not mentioned on the product label, the results may include inadequate dissolving of the powder, precipitation, or deactivation of the active pharmaceutical component before the vials are further diluted or administered.
- The University of Utah Drug Information Service and the American Society of Health-System Pharmacists (ASHP) have been collecting data about the lack of SW for injection and cooperating with various stakeholders to create ways to address the issue.
Both organizations have been in communication with the Food and Drug Administration (FDA), compounding specialists, and pharmaceutical manufacturers in an effort to gather as much information as possible to be distributed to pharmacy professionals.
What do you mean by WFI in pharmacy?
The Water for Injection (WFI) standard is a quality benchmark for water that is set by pharmacopeial organisations all around the world. The most important pharmaceutical products and applications, such as hemofiltration, irrigation, the production of some active pharmaceutical ingredients, implantable medical devices, and a variety of other uses, all require the use of WFI.
- This requirement applies to injectable drugs as well as hemofiltration and irrigation.
- Due to the fact that distillation was the sole treatment method that was considered appropriate in the past, water for injection has traditionally been made by this method.
- As time went on, developments occurred in processes such as reverse osmosis, electrodeionization, and ultrafiltration.
Additionally, manufacturers gained experience using membrane technology to produce highly purified water. As a result, regulators reevaluated which processes were necessary for the production of WFI. The result of these efforts was the harmonization of WFI laws among the main Pharmacopeias in 2017, which made it possible to produce WFI using alternatives that were based on membranes.
What is WFI and sterile WFI?
What Is the Purpose of Water for Injection? As was said earlier, WFI is a type of sterile water that is utilized in the process of administering medications or treatments to patients via intravenous route. In addition to its application in the production of solutions, it is also put to use as a cleaning agent.
What is USP sterile water?
DESCRIPTION. Sterile Water for Injection, USP is distilled water that has been sterilized and is nonpyrogenic. It is packaged in a single-dose bottle and is intended for intravenous administration once an appropriate solute has been added. It is also possible to utilize it as a container for dispensing diluent, if desired. There has been no addition of an antibiotic or any other ingredient.
What is another name for sterile water?
Bacteriostatic Water And Purity – Bacteriostatic water is a sterile kind of water that has been brought to a pH between 4.5 and 7.0 in order to exclude any possibility of bacteria growing in it. In addition to that, it is formulated with a bacteriostat, which is a substance that inhibits the development of bacteria in any form.
Can u drink sterile water?
Sterile Water for Irrigation is not considered to be potable water and is not designed to be taken by mouth in any way.
Is sterile water the same as saline?
We investigated the viability of using sterile water as an irrigation solution during percutaneous nephrolithotomy and came to the conclusion that it is safe to do so (PCNL). The components and procedures: This study included a total of forty-four individuals who were diagnosed with renal calculi.
These patients were then randomly assigned to one of two groups for PCNL. The calculi were approached by a single subcostal access using an Amplatz sheath. Sterile water or an isotonic saline solution was utilized as the irrigation fluid during the procedure. Before and 12 hours after the procedure, measurements were taken of creatinine, sodium, potassium, haptoglobin, and serum hemoglobin and haptoglobin.
During the procedure and for the next 24 hours afterward, the patients were monitored for any symptoms that would point to transurethral resection of the prostate syndrome. Results: There was no statistically significant difference between the two groups in terms of the mean calculus size, irrigation volume, irrigation time, or age.
Hemolysis was seen in 10 individuals in the group that received sterile water and 9 patients in the group that received saline. In the group that was given sterile water, the average change in haptoglobin level was -1.7 +/- 59 mg/dL, while the change in the saline group was 11 +/- 55 mg/dL. In addition, the mean decrease in plasma sodium level was -2.2 +/- 4.7 and -0.4 +/- 3.8 correspondingly in the sterile water group and the saline group.
There was no statistically significant difference between the two groups in any of these or any other laboratory data that were compared. There was no case of transurethral resection of the prostate syndrome or the requirement for a blood transfusion among the patients.
What is the difference between PW and WFI?
The temperature of the purified water in a PW loop is maintained at room temperature, whereas the temperature of the water for injection (WFI) in a WFI loop is maintained between 80 and 90 degrees Celsius. In point of fact, this indicates that a loop heat exchanger is required in order to both heat and cool the PW while the sanitation process is being carried out, as well as to heat the WFI and keep its temperature stable.
What is the temperature of WFI?
The WFI Process, Step F 0 – Heat is an efficient method for preventing the growth of microorganisms. The water is purified using heat throughout the various stages of the heat distillation process. The process begins by heating the feed water in the condenser, then continues on to the column pre-heaters in each stage, and finally concludes with the first column, which uses steam from the plant and exposes the incoming water to the highest temperature.
- In each column, the process of feed water to flash vaporization and condensing to final distillate takes place, culminating at the condenser output, which is normally between 95 and 99 degrees Celsius for the MWS.
- Eight bars is the typical maximum working pressure for plant steam, and 175 degrees Celsius is the temperature that corresponds to this pressure.
The temperature of the WFI processing, also known as the exposure temperature of feed water and WFI, is normally between 143 and 175 degrees Celsius throughout the process of manufacturing MWSs. When compared, the normal working temperature for the production of WFI using vapor compression technology is substantially lower, falling between between 100 and 105 degrees Celsius.
- This indicates that the F 0 value reached during a procedure involving multiple-effect distillation greatly exceeds the equal sterilization batch exposure period, but the F 0 value during a method involving vapor compression distillation does not reach 15 at any point throughout the process.
- The amount of time that this process spends “dwelling” in water is insufficient, and the temperature is inadequate.
Because the exposure time of water passing through the equipment is measured in seconds rather than minutes, a high temperature in exposure is critically important to achieving acceptable sterility levels that ensure a Sterility Assurance Level (SAL) of 10 -6.
- This is because the exposure time of water passing through the equipment is measured in seconds.
- Calculating the F0 value for the WFI system is an essential step since it is an essential component for ensuring the safety of any production of this kind.
- The heat exposure of water is not only assessed using the temperature that is greatest in the first column, but the F 0 value also accumulates in every step of the process in which the exposure temperature is higher than 100 degrees Celsius.
When looking at water exposure in the WFI process at temperatures greater than the reference point of 121.1 degrees Celsius, an exponential increase in F0 accumulation can be seen. This is because the F0 accumulation is exponential. For instance, in the first column, the temperature of the feed-water might reach 170 degrees Celsius when operating at a plant steam pressure of eight bars.

What is LVP and SVP?
A drug that is intended for injection through the skin or another external boundary tissue, rather than through the alimentary canal, is known as a parenteral drug (LVP, SVP). This allows the active substances that the drug contains to be administered, using gravity or force, directly into a blood vessel, organ, tissue, or lesion.
- They are said to be “infused” when they are given to a human being intravenously (IV), “injected” when they are given to a human being intramuscularly (IM), or “subcutaneously” (SC).
- A large volume parenteral, also known as an LVP, is a container for a single dosage that has a capacity of more than 100 milliliters and is terminally sterilized by the use of heat.
The term “small volume parenteral” (SVP) is used to refer to all parenteral products that are not large volume parenterals (LVP), with the exception of biologicals.
What type is WFI?
A grade of water known as WFI is one that satisfies the purity requirements necessary for the production of injectable medications.
Can you drink WFI water?
Is the water used for water for injection (WFI) safe to drink? Although it is possible to consume WFI, doing so would be a very inefficient use of one’s resources in the absence of a compelling reason to do so. Because of how expensive it is to make, under normal circumstances you would not consume it because of how much it costs. People who are already healthy won’t gain from this in any way.
Is WFI purified water?
WATER FOR INJECTION (WFI) – In April of 2017, the PhEur 9.1 monograph 0169 was changed to enable WFI production with a purification technique equal to distillation. This harmonizes the regulations of the PhEur monograph with those of the USP and JP methods.
- This modification made it possible for membrane-based processes to be approved for use in WFI manufacturing, with specific considerations for the microbiological control safety guarantees that were needed in follow-up recommendations for GMP Annex 1 and Q&A from the European Medicines Agency (EMA).
- The manufacturing method that uses membranes is referred to as “Membrane WFI” or “Ambient WFI.” A two-pass RO, ion exchange, and ultrafiltration (UF) technique is becoming increasingly widespread, despite the fact that there is no established procedure for ambient WFI.
Going around in reverse order: • Ultrafiltration can be utilized to retain up to four logs of endotoxins and pyrogens. In the pharmaceutical industry, ultrafiltration units (UFs) are typically designed for a molecular cut-off weight (MWCO) of 10,000–20,000 Dalton, however certain applications require a MWCO of 6,000 Da.
• Continuous electrodeionization, also known as CEDI, is an ion exchange process that involves the utilization of DC electric current for the online regeneration of the resins. This method is typically utilized in place of replaceable or chemically regenerated systems, both of which present a potential for contamination.
CEDI is a polishing method that eliminates any minerals, CO2, NH4, SiO2, and TOC that can be left over after the RO process. • Although single-pass RO is allowed, two-pass RO provides “added assurance of the maintenance of the quality of the water produced,” as stated in the EMA Q&A document.
- This is because the second membrane acts as a barrier to any microorganisms that make their way through the membrane or o-ring defects, or that grow on the backside of the first-pass membrane.
- Single-pass RO is still permitted.
- In addition, pH correction is frequently utilized in conjunction with the second pass to reject excess CO2 and ensure the reliable operation of subsequent CEDI modules.
This is done in order to maximize the efficiency of the CEDI process.

Water that is suitable for injection must be of an exceptionally high quality and free of major contaminants. For the preparation of solutions that will be administered through injection, a sterile form is utilized. In most cases, additional ingredients are required to be added to the solution before it may be put to such use in order to make it more or less isotonic.
- It may be administered subcutaneously, into a vein, or into a muscle by the use of an injection.
- In the manufacturing process, a version that is not sterile may be utilized, and the procedure of sterilization may take place at a later stage.
- Red blood cell destruction is a potential side effect of administering it intravenously into a vein before adjusting the concentration to be nearly isotonic.
This can eventually lead to issues with the kidneys. A fluid overload may also occur as a result of an excessive quantity. Distillation or reverse osmosis are the two most common methods used to produce injection water. It should have a non-water component content of less than one milligram per one hundred milliliters.
What happens if you are injected with water?
Additional Information: A saline solution is sometimes used when a person is given fluids intravenously (for example, through an IV bag). This might be confusing for patients. If you were to inject massive quantities of clean water directly into a vein, this would cause the blood cells in your body to become hypotonic, which might result in death.
Rinsing the eyes with saline solutions can also be used to alleviate inflammation, remove foreign items and/or chemicals, and improve overall eye health. The water included in emergency eye wash bottles could or might not be saline, but it should have some kind of chemical preservative in it to prevent the growth of microorganisms including bacteria, fungi, algae, and acanthamoeba, which could cause an infection in the eye.
It is important to keep in mind that standard eye wash bottles, despite the fact that they could offer some instant relief in the event of an emergency, have a very restricted capacity and do not satisfy the specifications set out by ANSI or OSHA for emergency eye washes.
Can you use sterile water for IV flush?
Shortage of 0.9 Percent Sodium Chloride – After the whole supply of saline flush syringes has been delivered to the pharmacy, the following pharmacy conservation practices should be implemented:
- Reduce the quantity of floor stock to make room for reserve inventory.
- Procure and dispense Small syringes with a diameter of 10 milliliters that store lesser amounts of saline (for example, 3 milliliters or 5 milliliters of fill capacity) are designed to be used with central lines.
- Utilize the bag and vial systems as much as possible for drug reconstitution or dilution, as well as the preparation of premixed pharmaceuticals (as available)
- Think about using different techniques for reconstitution or dilution, like infusions that have been prepared by the pharmacy.
- Small quantities of sodium chloride, 0.9%, should be kept on hand for the formulation of medications.
Utilize the nursing water saving practices outlined in the following paragraphs for saline flushes:
- Eliminate needless medication dilution
- To the greatest extent feasible, save saline flushes with a diameter of 10 milliliters for the central lines.
- When initiating IV lines and giving blood products, big capacity bags containing 0.9 percent sodium chloride should be used.
- Keep 10 mL vials of 0.9% sodium chloride on hand so that they may be used in the emergency code cart kits that are supplied from the pharmacist (together with EPINEPH rine).
- You should NOT attempt to dilute or reconstitute drugs by first drawing up the contents of the medication into a flush syringe that is prefilled with 0.9% sodium chloride and then delivering the product that is created by this process.
- When flushing VADs before and after administering medicine, DO NOT use the same saline syringe more than once.
- When flushing VADs, sterile water intended for injection should NOT be used.
- If an intravenous line, central line, or saline lock has not been used in at least 24 hours, remove it.
- Utilize central VADs that have a lumen count that is as low as possible.
- Get syringes for a saline flush from a pharmacy that outsources their products.
- In the event of a total blackout: In order to ensure that sterile compounding rules are met, you should have the pharmacist produce saline flushes (for example, by repackaging them from bags and labeling them correctly). A beyond-use date should be assigned depending on the USP.
Can sterile water for injection be used for inhalation?
Water that has been sterilized and appropriately packed is used to make McKesson sterile water for inhalation. This water is made from water that is intended for injection. When preparing inhalation solutions and using inhalators, you should always use sterile water for the inhalation process.
