Foundayo (orforglipron) and Wegovy (semaglutide) belong to a class of drugs known as glucagon-like peptide-1 (GLP-1) receptor agonists. GLP-1 medications work by mimicking a natural hormone that regulates appetite in the brain. They tell your body you are full, which helps you eat less and lose weight.

The drugs do similar things and have similar side effects, but differ in how you take them. The table below compares the main features of Foundayo and Wegovy.

You take Foundayo and Wegovy in different ways. However, for both drugs, you start at a low dose and increase it gradually until you reach a maintenance dose. However, it’s not necessary to increase the dose each month if the current dose is working well for you.

Foundayo is a tablet you swallow once a day, with or without food. The dosage starts at 0.8 milligrams (mg) daily and can go up to 17.2 mg.

Wegovy was first approved as a once-weekly injection that you give yourself in the stomach, thigh, or arm. However, it’s now also available as a once-daily tablet that you take on an empty stomach with a small amount of water.

Wegovy injections usually start at 0.25 mg once weekly and can be increased to 2.4 mg or 7.2 mg. The tablet version goes from 1.5 mg up to 25 mg daily.
