Medicine Description visudyne 15mg
Visudyne 15 mg injection is a medication that contains verteporfin, a photosensitizer used in photodynamic therapy. Upon intravenous administration, verteporfin preferentially accumulates in abnormal blood vessels in the retina. When exposed to specific wavelengths of light, verteporfin undergoes a photochemical reaction, generating reactive oxygen species. This process leads to damage and occlusion of abnormal blood vessels, thereby reducing their permeability and mitigating associated conditions such as neovascular age-related macular degeneration. By targeting these pathological vessels, Visudyne helps to limit vision loss due to retinal diseases characterized by abnormal angiogenesis.
Indications and Uses of Visudyne 15 mg injection
- Age-related macular degeneration with choroidal neovascularization
- Pathological myopia with associated choroidal neovascularization
- Other eye conditions related to the proliferation of abnormal retinal blood vessels
Side Effects of Visudyne 15 mg injection
- Photosensitivity reactions
- Pain at the injection site
- Visual disturbances, including blurred vision
- Nausea
- Headache
- Skin reactions following light exposure
Storage and Handling
Visudyne 15 mg injection should be stored at 2°C to 8°C (36°F to 46°F) and protected from light. It should not be frozen. After preparation, the solution may be stored at room temperature and must be used within a specific timeframe to ensure its efficacy.
Patient Advice and Precautions
Patients should be advised to avoid direct sunlight or bright light exposure for a period after treatment to prevent photosensitivity reactions. It is essential to inform healthcare providers of any previous allergic reactions to verteporfin or similar medications. Regular follow-up appointments are crucial to monitor treatment efficacy and any potential side effects.
