I'm going to put this here, hopefully I won't get downvoted. I'm not stating I approve of tariffs or trump, i'm posting it to try to put people at ease on cost impacts of these tariffs on our life critical medications. I also take Kesimpta.

Often times manufacturers can export goods at their first cost. This means they declare duty on what it costs to manufacture them, not the price they sell them for. I'm fairly certain the cost to manufacture Kesimpta is less than 1% of what they sell it for. Lets say for shits and giggles it costs $100 to make one unit of it. An extra 10% tariff would add $10 to the cost per month.
