Safety points to know
Phentermine can raise heart rate and blood pressure and can cause trouble sleeping and dry mouth. It is not suitable for everyone, including people with certain heart conditions, uncontrolled high blood pressure, an overactive thyroid, glaucoma, or those taking or recently taking an MAOI.
Qsymia shares those cautions and adds others from topiramate, including a risk of birth defects, mood changes or suicidal thoughts, tingling, memory or attention problems, kidney stones and changes in blood chemistry. People who can become pregnant need a negative pregnancy test and reliable birth control while taking it. Do not stop Qsymia suddenly without talking to your physician.
Controlled-substance prescribing
Because both medicines are controlled substances, whether your physician can prescribe them by video visit depends on your evaluation and on the federal and Pennsylvania rules in effect at the time. Dr. Alatassi is Pennsylvania-licensed and DEA-registered.
