Adverse effects reported by trial participants treated with Siliq include headache, arthralgia, fatigue, oropharyngeal pain, and diarrhea.

With this latest nod, Trulicity is the first medication of its class allowed to be used in combination with mealtime insulin or basal insulin.
 
The most common side effects reported by trial patients treated with Trulicity included nausea, diarrhea, vomiting, abdominal pain, and decreased appetite. The drug also has a boxed warning alerting patients and prescribers to a potential risk of thyroid tumors.
 
7. Xermelo

Xermelo is indicated, in combination with somatostatin analog (SSA) therapy, for the treatment of adults with carcinoid syndrome diarrhea that is not adequately controlled by SSA therapy alone.
 
The drug works by inhibiting carcinoid tumors’ production of serotonin, reducing the frequency of carcinoid syndrome diarrhea.
 
The most common adverse events associated with the use Xermelo include nausea, headache, increased levels of the liver enzyme gamma-glutamyl transferase, depression, accumulation of peripheral edema, flatulence, decrease appetite, and fever.
