What is Lomaira?
Lomaira is similar to an amphetamine. This medicine stimulates the central nervous system (nerves and brain), which increases your heart rate and blood pressure and decreases your appetite.
Lomaira may also be used for purposes not listed in this medication guide.
You should not use Lomaira if you have glaucoma, overactive thyroid, severe heart problems, uncontrolled high blood pressure, advanced coronary artery disease, extreme agitation, or a history of drug abuse.

if you take other diet pills.
