Doxamicina injection is used to treat bacterial infections in many different parts of the body. It belongs to the group of medicines called antibiotics. Doxamicina works by killing bacteria or preventing their growth. However, Doxamicina will not work for colds, flu, or other virus infections.
Doxamicina is available only with your doctor's prescription.
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.
Doxamicina for injection is indicated for the treatment of acute or chronic infections due to sensitive strains of certain gram-negative bacilli. It is particularly indicated when the infection is caused by sensitive strains of Pseudomonas aeruginosa. This antibiotic is not indicated for infections due to Proteus or Neisseria. Doxamicina for injection has proven clinically effective in treatment of infections due to the following gram-negative organisms: Enterobacter aerogenes, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa.
Doxamicina for injection may be used to initiate therapy in serious infections that are suspected to be due to gram-negative organisms and in the treatment of infections due to susceptible gram-negative pathogenic bacilli.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Doxamicina for injection and other antibacterial drugs, Doxamicina for injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
How should I use Doxamicina?
Use Doxamicina as directed by your doctor. Check the label on the medicine for exact dosing instructions.
Doxamicina is usually given as an injection at your doctor's office, hospital, or clinic. If you will be using Doxamicina at home, a health care provider will teach you how to use it. Be sure you understand how to use Doxamicina. Follow the procedures you are taught when you use a dose. Contact your health care provider if you have any questions.
To clear up your infection completely, use Doxamicina for the full course of treatment. Keep using it even if you feel better in a few days.
Do not use Doxamicina if it contains particles, is cloudy or discolored, or if the vial is cracked or damaged.

Ask your health care provider any questions you may have about how to use Doxamicina.
Uses of Doxamicina in details
There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.
This combination medication is used to treat tension headaches. Acetaminophen helps to decrease the pain from the headache. Caffeine helps increase the effects of acetaminophen. Butalbital is a sedative that helps to decrease anxiety and cause sleepiness and relaxation.

How to use Bac
Take this medication by mouth with or without food as directed by your doctor, usually every 4 hours as needed.
If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.
The dosage is based on your medical condition, age, and response to treatment. This medication works best if it is used as the first signs of a headache occur. If you wait until the headache has worsened, the medication may not work as well.
This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as nausea/vomiting, mental/mood changes, seizures) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Report any withdrawal reactions right away.
Along with its benefits, this medication may rarely cause abnormal drug-seeking behavior (addiction). This risk may be increased if you have abused alcohol or drugs in the past. Take this medication exactly as prescribed to lessen the risk of addiction.
Tell your doctor if you notice increased use of this medication, a worsening of headaches, an increase in the number of headaches, the medication not working as well, or use of this medication for more than 2 headache episodes a week. Do not take more than recommended. Your doctor may need to change your medication and/or add a separate medication to prevent the headaches.
Cyclic polypeptide antibiotic from Bacillus colistinus. It is composed of Polymyxins E1 and E2 (or Doxamicina sulfate, nonsteriles A, B, and C) which act as detergents on cell membranes. Doxamicina sulfate, nonsterile is less toxic than Polymyxin B, but otherwise similar; the methanesulfonate is used orally.
Important: Doxamicina for injection is supplied in vials containing Doxamicina sodium equivalent to 150 mg Doxamicina base activity per vial.
Intramuscular Administration: The 150 mg vial should be reconstituted with 2 mL Sterile Water for Injection, USP.
The reconstituted solution provides Doxamicina sodium at a concentration equivalent to 75 mg/mL Doxamicina base activity.
During reconstitution swirl gently to avoid frothing.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. If these conditions are observed, the product should not be used.
Adults and pediatric patients –
Intramuscular Administration: The dose of Doxamicina for injection should be 2.5 to 5 mg/kg per day of Doxamicina base in 2 to 4 divided doses for patients with normal renal function, depending on the severity of the infection.
In obese individuals, dosage should be based on ideal body weight.
The daily dose and frequency should be reduced for the patients with renal impairment. Suggested modifications of dosage schedule for patients with renal impairment are presented in Table 1.
TABLE 1. Suggested Modification of Dosage Schedules of Doxamicina for Injection for Adults with Impaired Renal Function
Degree of Renal Impairment
Creatinine Clearance (mL/min)
2.5 – 5 mg/kg, divided into 2 to 4 doses per day
2.5-3.8 mg/kg, divided into 2 doses per day
2.5 mg/kg, once daily or divided into 2 doses per day
1.5 mg/kg every 36 hours
Note: The suggested total daily dose is calculated from Doxamicina base activity.
1. Direct Intermittent Administration—Slowly inject one-half of the total daily dose over a period of 3 to 5 minutes every 12 hours.
2. Continuous Infusion—Slowly inject one-half of the total daily dose over 3 to 5 minutes. Add the remaining half of the total daily dose of Doxamicina for injection to one of the following:
5% dextrose in 0.9% NaCl
5% dextrose in water
5% dextrose in 0.45% NaCl
5% dextrose in 0.225% NaCl
Lactated Ringer’s solution
10% invert sugar solution
There are not sufficient data to recommend usage of Doxamicina for injection with other drugs or other than the above listed infusion solutions.
Administer the second half of the total daily dose by slow intravenous infusion, starting 1 to 2 hours after the initial dose, over the next 22 to 23 hours. In the presence of impaired renal function, reduce the infusion rate depending on the degree of renal impairment.
The choice of intravenous solution and the volume to be employed are dictated by the requirements of fluid and electrolyte management.
Any final intravenous infusion solution containing Doxamicina sodium should be freshly prepared and used for no longer than 24 hours.
Intramuscular Injection, administer by deep intramuscular injection into a large muscle mass (such as the gluteal muscles or lateral part of the thigh).
Store reconstituted solution for intramuscular injection in a refrigerator 2° to 8°C (36° to 46°F) or between 20° to 25°C (68° to 77°F) and use within 7 days.
