Health Signal Pro is an Edinburgh-based health information publisher, established in 2025, that examines medication claims against current US prescribing information and named clinical trials. Its editorial method—Ping, Trace, Flag, Post—starts with a reader’s claim, checks the relevant label, identifies what the evidence does not support, and publishes the findings with clear cautions and a named medical reviewer. The site states that it does not dispense medicines or provide a checkout.

Its coverage focuses on nine medicines: sildenafil, tadalafil, vardenafil, ivermectin, isotretinoin, prednisone, gabapentin, ciprofloxacin, and metformin. Drug notes and a 27-file journal explore practical use, trial evidence, medication history, dosing considerations, and risks such as interactions, kidney function, tendon injury, and tapering. The site also references sources including FDA labels, named trials, WHO lists, MedlinePlus, and CDC materials.

Three physicians sign and answer questions within their areas: Dr. Julian Osei, Dr. Elena Vasquez, and Dr. Nathan Whitfield. Health Signal Pro presents its content as educational reading, emphasizing label-based limits and safety flags rather than treatment or purchasing advice.
