Medicine during Chauvihar or upvas: what has your guru advised?

A question many families quietly struggle with: a parent needs a night-time tablet, or someone keeping upvas falls ill.

What have gurus or sadhvijis told you about medicine during a vow, and about the agaar (exceptions) taken with the pachchakkhan? Please say which tradition you are describing.
