Fasting for those taking psychiatric medications

Honorable Rabbi Fried, shalom! In your newsletter Azamra LiShimchah 5783 dealing with the laws of Tisha B'Av, the following question is presented: Should a person suffering from depression fast on Tisha B'Av? The answer is that a person suffering from mental health issues is exempt from fasting, as stated in chapter 554, paragraph 6. If we follow this ruling, about 10% of the population is exempt from fasting. In Israel Today newspaper, it states that in 2022, 7.5% are taking anti-depression and anxiety medications, and in the Haaretz newspaper, it was reported that in 2018, about 20% of the adult population is taking them. My question is whether the Rabbi's exemption from fasting is specifically for those in severe condition, etc., because there are completely normative people who take medication. Also, regarding the types of medications: there are different types and dosages, for example, like the difference between taking Tylenol and an epidural injection that a woman takes during childbirth. With the blessing of the Torah.

Shalom!
Each case is individual. Indeed, according to the basic law, anyone taking these medications should check if fasting does not adversely affect him. And if there is a concern, he should not fast.
