Phentermine is an oral stimulant-based appetite suppressant. Rivas prescribes it selectively, monitors response closely, and provides treatment in person at Maryland clinics only.
Safety & candidacy
Your Rivas provider evaluates you at your first visit and makes the determination. The information below offers general context about who this treatment may fit.
Common side effects
Side effects and their frequency vary by medication and patient. Your provider will review risks, contraindications, and medication interactions during your evaluation.
Phentermine works through the central nervous system rather than the GLP-1 pathway. It increases norepinephrine signaling to help reduce appetite and is generally taken during waking hours under provider direction.
It is an oral prescription option for patients who prefer a pill or may benefit from a different mechanism. The plan is based on medical history, current medications, blood pressure, prior response, goals, and tolerability.
Phentermine is FDA-approved for short-term weight management. Rivas may use it longer term under ongoing supervision when clinically appropriate; longer-term prescribing is off-label and requires continued monitoring.
A daily pill offers a non-injection option for appropriate patients.
Your care path
A Maryland provider reviews cardiovascular history, current medications, blood pressure, and weight.
The first follow-up is generally at two weeks to review response, sleep, side effects, blood pressure, and progress.
Rivas treats obesity as a chronic condition rather than framing regain as a personal failure. Follow-up supports maintenance, catches returning appetite or weight changes early, and lets the provider reconsider the plan over time. Individual results vary.
Every visit includes a provider visit, vitals and weigh-in, and medication. No separate pharmacy trip required.
