The main purpose of the study is to investigate the blood concentrations of dabigatran etexilate and rosuvastatin when taken alone compared to when taken together with lasmiditan in healthy participants. The safety and tolerability of dabigatran etexilate or rosuvastatin in combination with lasmiditan will also be evaluated in healthy participants. The study has two parts. Each part will last up to 17 days, not including screening.

Inclusion Criteria:

• Are overtly healthy
• Body mass index (BMI) of 18.5 to 35 kilograms per meter squared (kg/m²)

Exclusion Criteria:

• have known allergies to lasmiditan, dabigatran, rosuvastatin-related compounds or any components of the formulation of lasmiditan, dabigatran, rosuvastatin, or a history of significant atopy
• have an abnormal blood pressure and/or pulse rate as determined by the investigator
• have clinically significant abnormalities on electrocardiogram (ECG) as determined by investigator
• have a history or presence of cardiovascular, respiratory, renal, gastrointestinal, endocrine, hematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; of constituting a risk when taking the study interventions; or of interfering with the interpretation of data. Appendectomy, splenectomy, and cholecystectomy are considered as acceptable
• have any medical conditions, medical history, or are taking any medications that are contraindicated in the dabigatran etexilate or rosuvastatin label
• are intending to use over-the-counter or prescription medication, including dietary supplements, traditional medicines, and herbal supplements, within 14 days prior to dosing and until study discharge (apart from occasional acetaminophen, hormonal contraception, or hormone replacement therapy)

• Part 2 only: have c.34AA, c.421AA, or c.34GA/421CA genotypes of ABCG2 as determined through genotyping
