Rifadin is a powerful antibacterial drug with the active ingredient rifampicin. The class of drugs to which Rifadin belongs is called rifampicin antibiotics. Rifampicins are a group of antibiotics that have potent antibacterial action against a wide range of bacteria. Their action is to inhibit the activity of bacterial RNA polymerase, resulting in disruption of bacterial RNA synthesis. This makes them particularly effective against many types of bacteria, including Mycobacterium tuberculosis (which causes tuberculosis), Staphylococcus aureus, Streptococcus pneumoniae and many others.

Rifadin para que sirve?

Rifadin, is used to treat a variety of infectious diseases, including tuberculosis, typhoid fever, leprosy and other bacterial infections. It causes bacteria to stop growing and multiplying, and then to die. The use of Rifadin is particularly effective in treating infections caused by bacteria that resist other classes of antibiotics.

Rifadin is available in capsule, tablet, and spray forms. The question of choosing between spray and pill depends on the specific situation, individual patient and disease characteristics. Here is a detailed consideration of both forms of the drug and their advantages in different cases.

Tablets (capsules)

Rifadin 300 tablets are usually more convenient to use as they can be swallowed whole with water, which is convenient for most patients. They provide a more stable dosage of the drug, which is important for optimal treatment effects. They are easier to store and carry as they do not require special storage conditions, unlike a spray. Tablets are usually preferred for the treatment of standard infections such as tuberculosis, when localized exposure to the affected areas is not required.


Rifadin spray, provides an option for topical application of the drug directly to the affected areas. This may be useful in the treatment of skin infections, wounds, or other superficial lesions. Systemic side effects are less likely to occur when using the spray, as the drug acts primarily locally. It is also preferred for patients with digestive problems, such as nausea or vomiting, as it does not require oral administration.

Rifadin spray, may be a better choice when treating skin infections, wounds, burns and other superficial lesions. For example:

Skin infections: Rifadin spray is effective in treating various skin infections, such as pyoderma (pustular skin lesions), boils, carbuncles, folliculitis, and fungal and viral skin infections.

  • Wounds and burns: For skin injuries such as cuts, scrapes, abrasions or burns, the spray may help prevent infection and promote faster wound healing.
  • Abscesses and External Soft Tissue Diseases: For abscesses, phlegmons, or other external soft tissue diseases, Rifadin spray may be used to reduce inflammation, kill pathogens, and speed up the healing process.
  • Oropharyngeal infections: In cases of throat, mouth, or other oropharyngeal infections, the spray may be used to apply topically to affected areas to help reduce symptoms and speed recovery.
  • Prevention of infections during medical procedures: Rifadin spray can be used to prevent infections during various medical procedures such as wound care, burns or skin manipulation.

Dosage of Rifadin 300mg tablets (capsules)

  • Treatment of tuberculosis: It is usually recommended to take 600–1200 mg of Rifadin per day for the treatment of active tuberculosis in adults. For children, the dosage can be calculated based on weight and age, usually 10–20 mg/kg of weight per day.
  • Prevention of tuberculosis: A low dose of Rifadin, usually 600 mg daily, may be used to prevent tuberculosis, especially in persons at high risk of infection (e.g., contacts).
  • Treatment of other infections: The dosage for the treatment of other infections caused by Rifadin sensitive microorganisms may vary and depends on the type of infection, its severity, and the site of localization.
  • Co-treatment of tuberculosis and HIV: In patients with tuberculosis and HIV infection, the dosage of Rifadin may be changed due to a possible interaction with other antiretroviral drugs. In this case, careful monitoring and dosage adjustment according to the physician's recommendations are necessary.

Rifadin side effects

  • Gastrointestinal disorders: One of the most common side effects is gastrointestinal disorders such as nausea, vomiting, diarrhea or abdominal pain. These symptoms can be mild and temporary, but in some cases require medical intervention.
  • Liver Dysfunction: Rifadin 300 may cause hepatic dysfunction, as manifested by changes in liver function values in biochemical blood tests, jaundice of the skin and sclera, and increased liver enzyme activity.
  •  Allergic reactions: In rare cases, allergic reactions to the drug may develop, manifested by skin rashes, pruritus, angioedema or anaphylactic shock.
  • Neurologic symptoms: Some patients may experience neurologic symptoms such as dizziness, headache, changes in taste sensation or neuritis.
  • Color change in bodily fluids: Use of Rifadin may cause urine, sweat, and tears to change to an orange color. This phenomenon is usually harmless, but may cause concern in patients.


  • Allergy: The first and main contraindication to the use of Rifadin, is a known allergy to the drug or its components. Patients experiencing an allergic reaction to rifampicin or other drugs in this class should avoid its use.
  • Liver failure: The drug should be used with caution in patients with impaired liver function or a history of liver failure, as it may aggravate the liver condition.
  • Patients with leukopenia: Rifadin may depress bone marrow function and cause leukopenia. Therefore, its use requires caution in patients with pre-existing disorders of hematopoiesis.
  • Treatment of children and pregnant women: For children and pregnant women, the use of Rifadin-rifampicin requires special attention and an evaluation of the benefits of treatment versus the potential risks to the child.

Interaction with other drugs

  • Anticoagulants: Rifadin may reduce the effectiveness of anticoagulants such as warfarin by accelerating their metabolism in the liver. This may lead to a decrease in prothrombin time and an increased risk of thromboembolic events.
  • Antituberculosis drugs: In concomitant use of rifadin-rifampicin with other antituberculosis drugs, interaction is possible, as a result of which their pharmacokinetic parameters may change. For example, combination with isoniazid may increase toxicity of the latter.
  • Antiepileptic drugs: Acceleration of metabolism of antiepileptic drugs such as carbamazepine and phenytoin is possible, which may lead to a decrease in their effectiveness and increase the risk of seizures.
  • HIV drugs: Interaction of Rifadin with antiviral drugs for HIV treatment, such as protease or integrase inhibitors, may decrease their concentration in the blood and reduce their effectiveness.
  • Antibiotics: Interaction of Rifadin-rifampicin with other antibiotics may lead to changes in their pharmacokinetics and, as a result, worsening of treatment efficacy or increased toxicity.
  • Cardiovascular drugs: Combination of Rifadin-rifampicin with drugs for the treatment of cardiovascular diseases, such as antiarrhythmic agents or hypoglycemic drugs, may require adjustment of their dosage and monitoring of the patient's condition.

Duration of action and half life

Rifadin has a long and stable antibacterial action due to its high fat-solubility and ability to be actively concentrated in the tissues of the body. This allows maintaining effective concentrations of the drug in the body for a long time after its administration.

The half-life of Rifadin is about 3–4 hours. This means that every 3–4 hours, the level of the drug in the blood decreases by about half.

Because of Rifadin's long action and relatively short half life, it is usually taken once or twice a day. The exact number of doses per day and the length of the course depend on the type of infection, its severity, patient characteristics, and other factors.

It is important to adhere to a regular regimen to ensure stable concentrations of the drug in the body and maximize the effectiveness of treatment. Intermittent or improper use of Rifadin 300 mg, can lead to a decrease in the effectiveness of treatment and the emergence of resistance of microorganisms to the drug.

Price and cost

The cost of Rifadin can vary depending on the country and manufacturer. However, generic forms of this drug are usually available at a lower price.

Generic Rifadin is a medication that is an analog of the original drug Rifadin, which contains the active ingredient rifampicin. Generics are copies of the original medication produced by other pharmaceutical companies after the patents for the original medication have expired.

Generics undergo mandatory clinical trials to prove their effectiveness, safety, and quality. Because generics are produced after the patent on the original drug has expired, they are usually available at a lower price. This makes treatment available to more patients and can reduce healthcare costs.

Although generics are manufactured by other pharmaceutical companies, their production is strictly controlled to ensure that they meet high quality and safety standards. Many generics have quality certificates confirming that they meet international standards for the production of medicines.

Rifadin 300 mg is an effective drug widely used for the treatment of bacterial infections, including tuberculosis. Its long duration of action and relatively short half-life provide effective and stable treatment of various infections. Proper adherence to the regimen and duration of the course helps to achieve optimal treatment results and prevent the development of resistance to the drug.
