Injected Drug Use

Summary about Disease


(Focus: Risks associated with Injected Drug Use) Injected drug use carries significant health risks. These risks stem from the injection process itself (introducing bacteria/viruses directly into the bloodstream), the substances injected (potentially toxic or contaminated), and lifestyle factors often associated with drug use. These risks include infections (local and systemic), damage to veins and other tissues, overdose, and the spread of bloodborne diseases.

Symptoms


Symptoms vary widely depending on the specific health issue. Here are some examples:

Local Injection Site Infections: Redness, swelling, pain, warmth, pus discharge, abscess formation.

Systemic Infections (e.g., Bacterial Endocarditis): Fever, chills, fatigue, heart murmur, shortness of breath, night sweats.

Viral Infections (e.g., HIV, Hepatitis C): Often asymptomatic initially. Later symptoms vary widely depending on the stage of the infection and can include flu-like symptoms, jaundice, abdominal pain, fatigue, and weight loss.

Overdose: Slowed or stopped breathing, unresponsiveness, pinpoint pupils (opioids), rapid heartbeat, agitation, seizures (stimulants).

Collapsed Veins: Scarring, darkening of the skin along veins, difficulty finding veins for injection.

Cellulitis: Red, swollen, and painful skin around the injection site.

Causes


The primary cause is the injection of drugs using non-sterile equipment and/or injecting contaminated drugs. Specific causes include:

Sharing Needles and Syringes: Transmits bloodborne viruses (HIV, Hepatitis B, Hepatitis C) and bacteria.

Using Non-Sterile Equipment: Introduces bacteria and fungi into the bloodstream or tissues.

Injecting Contaminated Drugs: Drugs may be contaminated with bacteria, fungi, or other harmful substances during production, storage, or preparation.

Unsafe Injection Practices: Poor hygiene, injecting into areas with poor circulation, or repeated injections into the same site.

Compromised Immune System: Drug use can weaken the immune system, increasing susceptibility to infections.

Medicine Used


Medications vary widely based on the specific condition:

Bacterial Infections: Antibiotics (oral or IV).

Viral Infections (HIV): Antiretroviral therapy (ART).

Viral Infections (Hepatitis C): Antiviral medications.

Overdose (Opioid): Naloxone (Narcan).

Abscesses: Incision and drainage, followed by antibiotics.

Pain Management: Analgesics (use with caution, especially in individuals with a history of drug use).

Wound Care: Topical antibiotics, wound dressings.

Is Communicable


Yes, many health risks associated with injected drug use are communicable:

HIV: Highly communicable through sharing needles, syringes, and other injection equipment.

Hepatitis B: Communicable through sharing needles and unprotected sex.

Hepatitis C: Highly communicable through sharing needles and injection equipment.

Bacterial Infections: Some bacterial infections (e.g., Staphylococcus aureus) can spread through contact with infected wounds or contaminated surfaces, though this is less common than viral transmission through direct blood-to-blood contact.

Precautions


Never Share Needles, Syringes, or Other Injection Equipment: This is the most crucial precaution to prevent the spread of bloodborne diseases.

Use Sterile Needles and Syringes Every Time: Access sterile equipment through syringe service programs (SSPs).

Clean Injection Site: Use alcohol swabs to clean the skin before injecting.

Wash Hands Thoroughly: Before and after injecting.

Dispose of Needles Safely: Use a sharps container and follow local regulations for disposal.

Get Vaccinated: Vaccinations are available for Hepatitis A and B.

Consider Pre-Exposure Prophylaxis (PrEP) for HIV: If at high risk of HIV exposure.

Seek Medical Care Immediately: For any signs of infection or other health problems.

Substance Use Treatment: Seeking help to stop using drugs can eliminate the risks associated with injection.

Safe Injection Sites: In some locations, safe injection sites are available where people can use drugs under medical supervision with clean equipment.

How long does an outbreak last?


This is not an outbreak, but rather a persistent health risk associated with a specific behavior. The duration of specific infections varies:

Acute Infections (e.g., Bacterial Infections): Can resolve within days or weeks with appropriate treatment.

Chronic Infections (e.g., HIV, Hepatitis C): Can last a lifetime if untreated.

Outbreaks of Bloodborne Diseases: Outbreaks related to contaminated drug supplies can last weeks to months depending on the source and how quickly it is controlled.

How is it diagnosed?


Diagnosis depends on the suspected condition:

Local Injection Site Infections: Physical examination, wound culture.

Systemic Infections: Blood cultures, imaging studies (e.g., echocardiogram for endocarditis).

HIV: Antibody tests, viral load tests.

Hepatitis B and C: Blood tests (antibody and viral load).

Overdose: Clinical presentation (e.g., slowed breathing, unresponsiveness), toxicology screen.

Collapsed Veins: Physical examination.

Timeline of Symptoms


The timeline of symptoms varies greatly.

Injection Site Infections: Develop within days.

Overdose: Immediate.

HIV: Initial flu-like symptoms can appear weeks after infection. The chronic phase (AIDS) can take years to develop without treatment.

Hepatitis C: Many people are asymptomatic for years. Chronic liver disease can develop over decades.

Endocarditis: Symptoms can develop rapidly (acute) or gradually (subacute) over weeks or months.

Important Considerations


Stigma: Individuals who inject drugs often face stigma, which can prevent them from seeking medical care.

Substance Use Disorder: Addressing the underlying substance use disorder is crucial for long-term health.

Harm Reduction: Strategies like needle exchange programs and safe injection sites aim to reduce the harms associated with drug use.

Mental Health: Co-occurring mental health conditions are common and should be addressed.

Access to Care: Ensuring access to affordable and comprehensive healthcare is essential for this population.

Legal Issues: Fear of legal repercussions can deter individuals from seeking help.
