fotosensytyzujce

Fotosensytyzujące refers to substances or treatments that increase a person's sensitivity to light, particularly ultraviolet (UV) radiation. This heightened sensitivity can lead to adverse reactions upon exposure to sunlight or artificial UV sources. The term is often used in medical contexts, particularly in dermatology and photodynamic therapy.

Certain medications can cause photosensitivity as a side effect. These can include antibiotics, diuretics, nonsteroidal anti-inflammatory drugs (NSAIDs), and retinoids. When a person is taking these medications, even brief exposure to sunlight can result in sunburn-like reactions, rashes, or other skin irritations. This reaction is known as a photosensitizing reaction.

Photosensitizing agents are also intentionally used in photodynamic therapy (PDT). In PDT, a photosensitizing drug is administered, which is then activated by a specific wavelength of light. This activation creates a chemical reaction that destroys targeted cells, such as cancerous cells or abnormal skin tissue. The light source used in PDT is typically a laser or LED lamp.

Individuals experiencing photosensitivity should take precautions to protect their skin from light exposure. This includes wearing protective clothing, using broad-spectrum sunscreen with a high SPF, and avoiding prolonged sun exposure, especially during peak UV hours. If a photosensitizing reaction occurs, it's advisable to consult a healthcare professional.
