It is permissable to utilize it for medical reasons. However, it’s important to note that it doesn’t truly fix any medical issues, but instead masks the symptoms.
By “fix medical issues” do you mean completely cure them? Well, very few medications actually do that. Antibiotics that are used to treat bacterial infections, I guess. Chemotherapy, maybe, when it does work – but it often does not.
But, blood pressure pills don’t cure hypertension. Insulin doesn’t cure diabetes. Etc, etc.
But that doesn’t mean the Catholic Church frowns upon such medications or obligates every Catholic to try “natural methods” first (even for diseases such as hypertension or diabetes where some natural methods can help a lot). It certainly does NOT forbid the use of pain medications that are expressly designed to “mask the symptom” of pain, not actually fix the underlying cause. Because sadly, not all causes of pain can be cured.
Whenever this issue comes up I notice many Catholics see the Pill the same way some Baptist see “demon rum”. Or how some secular humanists see “demon guns”.
But since unfortunately many posters have left CAF and won’t be challenging the “demon Pill” narrative. Let me note that there some reproductive issues that cannot be cured even with “natural” treaments, and apparently per many who have experienced “Napro” many Napro practitioners rely heavily on surgery – hardly a “natural” treatment IMHO.
I think the use of hormonal treatments to treat medical conditions are mostly a question of prudence and self-searching to ask, “Is the contraceptive effect of this medication, something that I’m just tolerating, or eagerly accepting as a loophole in Church teaching?” Since I have certainly come across my share of Catholics who proudly state that they have a “medical reason” to take the Pill and happily embrace the contraceptive effects as a side benefit, and that strikes me as a tad bit legalistic.
But I also know that many Catholics do prayerfully decide that medications with contraceptive effects are indeed licit in their situation.
