What is Bacteriostatic Water?

Composed of sterile water and 0.9% benzyl alcohol and an organic preservative agent, bacteriostatic water resists bacterial growth and contamination [1]. It is commonly used to reconstitute or dilute therapeutic substances for injection, including intramuscular, intravenous, intradermal, and subcutaneous routes [1, 2].

Bacteriostatic water formulations for injection have pH levels of 4.5-7, averaging 5.7. These formulations are less expensive to produce and more widely available than comparable products, such as sterile water [3].

A mainstay in medical facilities, research labs, and beyond, bacteriostatic water resists contamination for up to 28 days after initial use. Unused vials can remain viable for years with proper storage [4]. It is considered an ideal sterile solution due to its low toxicity and minimal interference with drug effectiveness.

However, bacteriostatic water for injection may not be the best option in all cases, such as in neonatal or pregnant recipients, or in cases of subjects being administered certain medications [3, 5].

When preparing bacteriostatic water for injection, all product indications should be closely followed, including recommended dosages and injection schedules [4].

What is Bacteriostatic Water Used For?

The primary uses of bacteriostatic water are as follows:

  1. It is used as a solvent or dilutant for drugs or therapeutic compounds that call for aqueous injection.
  2. The preservative agent (0.9% benzyl alcohol) in bacteriostatic water allows packaging in multi-dose vials that resist contamination for up to 28 days when used with sterile needles. This significantly reduces the risk of infection [4].
  3. It is an efficient solvent and presents minimal interaction with most medications [6].
  4. Apart from medications, bacteriostatic water is also indicated for the reconstitution and injection of therapeutic research peptides and hormones [7].
  5. Suitable injection routes are determined by the type of solute, the recipient’s needs, and target rates of diffusion and metabolization. These include subcutaneous, intramuscular, intravenous, and intradermal injection routes [1].

When using bacteriostatic water for injections, certain precautions must be followed. Handlers should adhere to the exact indications or medical instructions. Contraindications for bacteriostatic water injections include newborn babies and cerebrospinal injections [2, 8].

Additionally, bacteriostatic water must always be mixed with a solute before injection. Failure to do so risks the development of hemolysis, damaging the red blood cells [9, 10].

Adverse reactions are rare and can include fever, infection, and thrombosis. If symptoms appear, injections should be discontinued pending medical consultation [9].


Bacteriostatic Water for Injections

Bacteriostatic water is commonly used for the injection of therapeutic compounds. Now we will explore some of the most exciting applications.

Bacteriostatic Water for Peptides

Research peptides present great potential in emerging clinical contexts, such as combating symptoms of cardiovascular and metabolic diseases, as well as improving reproductive health [11]. Typically available as lyophilized powders to maintain purity and integrity, peptides require reconstitution before injection [12].

Bacteriostatic water works well as a peptide solvent, reconstituting the compounds without compromising their effectiveness. Plus, peptide solutions made with bacteriostatic water resist contamination. Experts state that it may be necessary to run trials in order to select the best solvent for various peptides, and sodium chloride water should be avoided [12].

This is the method of peptide reconstitution with bacteriostatic water for injection [13]:

  1. Gather the following: alcohol swabs, bacteriostatic water, peptide powder, and a sterile syringe.
  2. Wipe down all materials with an alcohol swab.
  3. Withdraw approximately 1mL of bacteriostatic water from the vial and slowly transfer it into the peptide container.
  4. Do not agitate the solution, which can damage the peptides. Allow the powder to naturally dissolve until the vial is transparent. If available, sonication may be performed in order to speed up the process.
  5. If you notice that the powder does not properly dissolve, try a stronger solvent.
  6. Be sure to consult indications for exact dosage and concentration.

Bacteriostatic Water for HGH (Human Growth Hormone)

Human growth hormone has a range of therapeutic applications, from enhanced physical composition and performance, to treatment of hormone deficiency in adolescents and children [14, 15].

Injection of HGH is considered safe when prescribed by a doctor. Exogenous formulations are available in powder and liquid forms. For the reconstitution of HGH powder, bacteriostatic water is a great choice, as it preserves HGH solutions and efficiently dissolves lyophilized aggregates [16].

The proper reconstitution of HGH before injection closely follows the above method. Injections are best suited to fatty areas, such as the thigh or waist. Handlers should follow the applicable dosage and administration schedule [16]. For safe storage, adhere to manufacturer indications.

Bacteriostatic Water for HCG (Human Chorionic Gonadotropin)

The clinical applications of the hormone hCG include fertility enhancement in both women and men, as well as a supplement to TRT in male subjects [17, 18].

Often available as a lyophilized powder, hCG is best reconstituted with bacteriostatic water for injection due to the solvent’s efficiency and preservative agents. HCG solutions are to be refrigerated to prevent degradation [19].

Reconstitution follows the above method. The dosage and administration schedule should follow applicable recommendations [18, 19].

Bacteriostatic Water vs. Sterile Water

Both substances are sterile solvents formulated for use in medical settings. Though their features overlap, bacteriostatic water and sterile water have several significant differences. Let’s explore their points of similarity and difference to understand their appropriate uses. You may be surprised to learn that they are not interchangeable [5].

First, let’s break down the basics of sterile water. This solution has no antimicrobial agents. It is simply water that has gone through purification and distillation processes for its safe use in various therapeutic contexts, namely injections, dilution, and irrigation. Because it is vulnerable to contamination, it is sold in single-dose containers [5].

Similarities

These are the primary similarities between bacteriostatic water and sterile water [5]:

  1. Both sterile solutions are formulated for medical use.
  2. Both act as dilutants or solvents of substances to enable injection.
  3. Both may be used in the injection of peptides, hormones, and various medications, often reconstituted from lyophilized powder.
  4. Both are suitable for subcutaneous intravenous, intramuscular, and intradermal injections.
  5. Both have the dangerous side effect of hemolysis when injected alone.
  6. Both are unsafe for use in neonates.
  7. Both meet US Pharmacopeia (USP) standards.

Differences

Here are the key differences between bacteriostatic water and sterile water [5]:

  1. Their pH levels and chemistry are distinct. Bacteriostatic water has a 0.9% benzyl alcohol content and an average pH level of 5.7, while sterile water is free of additives with a pH level of 5.0-7.0.
  2. Bacteriostatic water’s preservative content prevents contamination for multiple doses, while sterile water may be contaminated after one use. So, the former is available in multi-dose containers that are viable for up to 28 days after opening, while sterile water comes in single-dose vials. The re-use of sterile water for injections is strictly prohibited.
  3. Bacteriostatic water solutions remain sterile and safe for longer due to the preservative agent.
  4. FDA indications vary regarding drug interactions. Some drugs can interact poorly with each solvent, and they are not considered universally interchangeable in clinical contexts.
  5. Sterile water is formulated for irrigation, such as rinsing wounds, unlike bacteriostatic water.
  6. Bacteriostatic water should not be used on individuals with benzyl alcohol allergies.
  7. Bacteriostatic water has wider availability and is simpler to manufacture.
  8. Specialists generally consider bacteriostatic water to be a more efficient solvent or dilutant.

Despite their similarities, bacteriostatic water and sterile water differ in a few key areas. Overall, specialists agree that bacteriostatic water for injection is safer and more effective in most cases. Its preservative content reduces the risk of contamination and infection, boosts shelf life, and enables optimal solvency for aqueous injection [6].

There may be cases in which sterile water is more appropriate, as outlined above. Follow medical advice and relevant indications for maximum safety and results when using bacteriostatic water for injections.
