Oral Herceptin

Hello, my wife has been on herceptin for at least 4 years now. She does get a regular mug a and all has been well. We rescently switched to the new Tdium herceptin version. Now this is a miracle drug. Kathy has had stage 4 for ever. She had mets to the bones and every scan lights up like a christmas tree with activity. Only 2 months on the tedium and some of the spots are disappearing. We thought they would be there forever! But hear they are getting smaller is a miracle. For the eyes, she always either complains of tearing or dryness. Hope this helps.
