What to Avoid While on Immunosuppressants

Immunosuppressants are medications designed to reduce the activity of the body’s immune system. These drugs are commonly prescribed for individuals who have received organ transplants, preventing the immune system from recognizing and attacking the new organ as foreign tissue. They are also widely used to manage autoimmune diseases, conditions where the immune system mistakenly targets and damages the body’s own healthy cells and tissues, such as lupus or rheumatoid arthritis. While these medications offer life-changing benefits by controlling disease progression and preventing organ rejection, they also diminish the body’s natural defenses against pathogens. This weakened immune response significantly increases susceptibility to various infections, making it important to understand and avoid certain risks.

Reducing Infection Risk

Individuals taking immunosuppressants face an elevated risk of infection, necessitating careful attention to their environment. Minimizing exposure to pathogens begins with avoiding crowded public spaces, especially during peak seasons for respiratory illnesses. Maintain distance from anyone who appears sick, as even common colds can pose a more serious threat to a weakened immune system.

Meticulous hand hygiene is a simple yet powerful defense against infection. Frequent and thorough hand washing with soap and water for at least 20 seconds is recommended, particularly before eating, after using the bathroom, and after touching surfaces in public. When soap and water are unavailable, alcohol-based hand sanitizers containing at least 60% alcohol can be used.

Interacting with pets requires specific precautions to prevent zoonotic infections, which are diseases transmissible from animals to humans. Individuals on immunosuppressants should ideally delegate tasks like cleaning litter boxes or handling animal waste, as these can contain parasites such as Toxoplasma gondii or bacteria like Salmonella. If these tasks cannot be delegated, wearing gloves and a mask is advisable, followed by thorough hand washing.

Gardening and contact with soil can also present risks due to the presence of bacteria, fungi, and molds, including Aspergillus and Pseudomonas. When engaging in gardening activities, wearing protective gloves and long clothing can prevent cuts and scrapes, which serve as entry points for pathogens. A mask should be considered when disturbing dry, dusty soil or compost piles to avoid inhaling airborne spores.

Safe water practices are equally important for preventing waterborne illnesses. Avoiding stagnant water, such as that found in decorative fountains, and unchlorinated sources like some wells or hot tubs, can reduce exposure to harmful microorganisms. For those with private well water, boiling water for at least one minute or using certified water filters (e.g., reverse osmosis or those with an “absolute” pore size of one micron or smaller) is recommended for drinking and cooking.

Despite these preventative measures, infections can still occur. Recognizing the signs of infection early is important, as symptoms may be subtle in immunocompromised individuals. Fever, chills, unusual fatigue, or localized redness and swelling can indicate a problem. Promptly contacting a healthcare provider for any suspected infection allows for timely diagnosis and treatment, which can prevent more serious complications like sepsis.
