Zantac
Zantac and its active ingredient ranitidine have been sold in the United States since 1983, originally only as a prescription, and later also as an over the counter treatment for acid indigestion, heartburn, and sour stomach. Tens of thousands of people used Zantac every year, not knowing the extent of its danger.
Singulair
Singulair has been on the market since 1998. It is "indicated for" (meaning it is supposed to treat) asthma, hay fever and allergies. From 1998 on, Merck has received reports of neuropsychiatric injuries, like OCD, depression, tics, tremors, and suidicality. Regardless, Merck has played down Singulair's risks.
Finally in March of 2020, the FDA forced Merck to add a "Black Box Warning" to Singulair's label. This is the strongest kind of warning the FDA can require.
