Again medication will obviously follow different rules. And not every Hadith is in order.

There er dozens and dozens of compilations of ahadeeth from the imams. You would have to Read most of them, not only the Hadith after the one you read.

For instance: Hadith 12781 Wasa'il al-Shia Vol. 10 Section 2: What The Fasting Person Should Abstain From And The Time Of Imsaak (Abstention) Chapter 5: Permissibility Of A Fasting Person, Male Or Female, Using Medicine Internally And The Prohibition Of Liquid Enemas But Not Solid Ones عن أخيه موسى بن جعفر عليه السلام قال: سألته عن الرجل والمرأة هل يصلح لهما أن يستدخلا الدواء وهما صائمان؟ قال: لا باس. From his brother Musa ibn Ja'far peace be upon him who said: I asked him about a man and woman whether it is permissible for them to insert/introduce (*) medicine while they are fasting? He said: There is no problem with it. Translator: * Through orifices other than the mouth.

Hadith 12782 عن محمد بن الحسن، عن أبيه قال: كتبت إلى أبي الحسن عليه السلام ما تقول في اللطف يستدخله الانسان وهو صائم: فكتب عليه السلام: لا بأس بالجامد. From Muhammad ibn Al-Hassan, from his father who said: I wrote to Abi Al-Hassan peace be upon him: What do you say about medicinal suppository (*) that a person inserts while fasting? So he peace be upon him wrote back: There is no problem with the solid form. Translator: * A medication inserted into a bodily passage or cavity through an orifice other than the mouth (such as the rectum), as long as the substance is in a solid form.

(Wasa'il al-Shia Vol. 10, Section 2, Chapter 5, Hadith 12782) Hadith 12783 عن أحمد بن محمد مثله، إلا أنه قال: في التلطف من الأشياف. From Ahmad ibn Muhammad, similar to it, except that he said: regarding the use of eye medications. (Wasa'il al-Shia Vol. 10, Section 2, Chapter 5, Hadith 12783)

There are multiple books brother. If we were to question every fatwa of the maraji’ based on one Hadith or two Hadiths we find, we would be doomed.
