I was diagnosed May 2007 with a breast carcinoma, most of it invasive--stage 1, grade 3, node negative, e.r.+, 1 cm., moderately high oncotype score of 29. I did chemo and radiation, and started tamoxifen at the end of March 2008. I am supposed to travel to southern India for 3 weeks from end December to mid January 2009. It's a spiritual trip to an ashram in a small rural town, and the temperature could reach 100 degrees farenheit. We're staying in a hotel with air conditioning, but yesterday I was told that it's not uncommon for the electricity to go out--not just in the hotel, but any, where and everywhere in this town, which is off the beaten track and not near a big city where one might find a lot of tourists, services, etc. I know that tamoxifen should be stored at temps. between 68 and 77 degrees F. I have several questions: If the electricity goes out and the tamoxifen is in 90- or 100-degree heat for any period of time, will the drug lose significant efficacy? More important, how much risk am I taking to my health/treatment if I cannot store the tamoxifen at the right temperature for 1, 2, or even 3 weeks if we lose electriciy? Finally, is there equipment or packaging I can take with me to protect the medicine from excessive heat? I really want to go on this trip, but I will cancel it rather than jeapardize my cancer treatment, esp. since it's only about 17 months since my diagnosis, and because I had an aggressive, grade 3 tumor.Please help! Thanks.
