Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves breathing pure oxygen (O2) in a pressurized chamber to enhance the delivery of the gas to tissues and promote healing. Understanding drug contraindications is crucial in hyperbaric medicine to prevent adverse effects and maximize the benefits of therapy.
In this article, we focus on the drugs that require caution during HBOT, highlighting the importance of thorough patient assessment and safe clinical practice.
Overview of Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy works by increasing the inspired concentration of the gas under elevated pressure, raising tension in blood and tissues beyond what ambient pressure and normobaric oxygen can achieve. The elevated level enhances wound healing, fights infections, reduces edema, and is indicated in a range of conditions, including carbon monoxide poisoning, decompression sickness, and radiation therapy complications.
This environment supports systemic oxygenation, but the therapy may also cause toxic effects such as pulmonary and CNS oxygen toxicity, requiring careful management. Patients considering hyperbaric treatment should always disclose their medication use to healthcare providers for appropriate planning.
Drugs That Are Contraindicated or Require Caution with HBOT
Bleomycin
This chemotherapy drug is associated with the development of interstitial pneumonitis and fibrosis. Fatal cases have been reported in patients exposed to high concentrations after bleomycin therapy. HBOT is contraindicated or must be delayed for several months after bleomycin treatment, with a thorough pulmonary evaluation required before commencing treatment.
Doxorubicin
Concurrent administration with HBOT has been shown in studies to increase cardiac toxicity risk. It is advisable to discontinue doxorubicin before starting treatment to prevent adverse cardiac effects.
Cisplatin
Cisplatin may impair wound healing, a key effect of wound care and radiation injury, making it a relative contraindication. HBOT should ideally be started after cisplatin therapy completion, unless in emergencies.
Disulfiram
This drug inhibits superoxide dismutase, reducing free radical scavenging and increasing toxicity risk, including seizures and pulmonary complications during HBOT. It should be discontinued before treatment.
Mafenide Acetate (Sulfamylon)
The medication is a topical antibiotic used to prevent and treat infections associated with burn. Because it can increase the risk of toxicity and seizures, it is recommended to discontinue this treatment before undergoing therapy. Patients should always consult their healthcare provider before stopping or adjusting any prescribed medication.
Vasoconstrictors
Drugs that cause blood vessels to narrow (constrict), which reduces blood flow and increases blood pressure, such as nicotine, caffeine, and illicit substances (cocaine, amphetamines), are contraindicated as they reduce cardiac output and tissue perfusion, limiting the beneficial effects of the therapy.
Managing Drug Contraindications in Clinical Practice
Before starting treatment, a comprehensive patient evaluation includes a thorough review of the patient’s medication history, clinical condition, and potential substance interactions. Strategies to manage contraindications involve timing drug discontinuation appropriately, adjusting exposure parameters, and incorporating monitoring protocols to detect early signs of toxicity or adverse reactions. Collaboration among hyperbaric medicine specialists, oncologists, and primary care providers is essential to optimize patient safety and therapy effectiveness.
