I have recently finished a long treatment program for severe psoriasis, after which I was instructed to moisturize the areas twice a day. In addition, I have a medicinal gel to apply to any spots which reappear, also twice a day. Normally, I skip Shabbat and maximum pour oil over the areas. Now, with Rosh Hashana being followed directly by Shabbat, I am worried about 3 days without the medicinal gel for the trouble areas. (I don’t know if it is important to the Rav, but it is a clear ointment, relatively loose and one is supposed to use the applicator itself to spread it.) Am I allowed to use it with a “shinui”? Is there a difference whether it is Rosh Hashana or Shabbos? Thank you so very much for your help!
Wish you and your and all of Am Yisrael a Ktiva and Hatima LShana Tova LAlter LHaim Toivim
The halachot of taking medications are the same on Yom Tov as on Shabbat, therefore it wouldn’t be permitted for you to apply the gel. I would suggest that you apply a generous amount of it before Yom tov so hopefully it will last you for longer.
As a side point, regarding applying oil, I understand that applying the oil will not be an issue mimariach (smearing), but I would be interested to know why applying oil to the areas that you want to heal would be different than healing it with a medicated gel.
Have a Kesiva Vchatima Tova, and I wish that your Yom Tov and Shabbos should pass without having any need to use anything.:
