Memodyne & Photosensitivity: A Sun Exposure Warning Worth Reading

This is a specific, less-discussed safety detail worth understanding on its own: St. John's Wort is associated with increased skin sensitivity to sunlight in some people.

Why this matters

St. John's Wort has documented associations with photosensitivity — increased skin sensitivity to UV light — a real, if less commonly discussed, effect distinct from its more widely known medication interactions.

What to actually do about it

• Use sun protection if you spend extended time outdoors after starting
• Watch for unusual sunburn or skin reactions in the first few weeks
• Mention this to your doctor if you have fair skin or a history of sun sensitivity
• Stop use and consult a doctor if you notice unusual skin reactions
