(Qsymia, controlled appetite suppressant + anticonvulsant)
Qsymia is an FDA-approved combination of phentermine (appetite suppressant) and topiramate (anticonvulsant) in extended-release form. It produces greater weight loss than either drug alone. Long-term use is approved, but requires medical screening for cardiovascular disease, glaucoma, and psychiatric conditions. Teratogenic in pregnancy.
Long-term
FDA-approved combination with extended-release; teratogenic in pregnancy
Phentermine/topiramate ER produces mean 10% weight loss at the higher dose in clinical trials. Extended-release allows longer use than phentermine alone. Cognitive side effects and increased heart rate are possible. Absolutely not for pregnancy or women of childbearing potential without strict contraception.
People who did well on phentermine and need help with cravings as well as hunger.
Two medicines in one capsule: phentermine cuts appetite, topiramate dulls cravings. The same pairing as the brand Qsymia.
Topiramate can cause birth defects. Use reliable contraception and stop it at once if you become pregnant.
3–5 kg in 12 weeks (phentermine); up to 10% body weight (combination)
increased alertness and motivation (stimulant effect)
blood pressure and heart rate require close tracking
mood, anxiety, and sleep need supervision
Day 1
Video consultation with a US-licensed physician. Medical screening: blood pressure, heart rate, ECG may be required. Detailed discussion of risks, benefits, and contraindications. Informed consent required.
1Week 1
Start your dose (low dose for phentermine). Appetite suppression often noticeable within days. Energy increases. Monitor for jitteriness, heart palpitations, or insomnia.
2Weeks 2–4
Weight loss accelerates. Appetite remains suppressed. Your physician checks in weekly or biweekly to monitor cardiovascular and psychological effects.
3Weeks 5–12
Steady, significant weight loss. Physician continues close monitoring. At week 12 (or sooner if phentermine alone), plan for pause or switch to longer-term option.
4Week 12+
Maintenance or transition: if using phentermine alone, pause it (cannot use continuously). Phentermine/topiramate ER may continue if tolerated. Your physician guides next steps.
5Individual results vary. Benefits reflect what Zepym Health members commonly report to their physician at check-ins; they are not the results of a clinical trial.
This is the starting dose the pharmacy prints on the label. Your physician sets yours and adjusts it with you.
A sample week
Once a day
In clinical trials, phentermine/topiramate ER produced mean 10% weight loss, nearly double that of phentermine alone. Effects persist for a year of continuous use.
The combination is potent but requires careful screening for heart disease, glaucoma, and psychiatric conditions. Cognitive effects ('topiramate fog') and increased heart rate occur in some users.
Learn morePhentermine and phentermine/topiramate are controlled medications with significant risks. Do not use with uncontrolled high blood pressure, heart disease, recent heart attack or stroke, glaucoma, or history of substance abuse. Cardiovascular effects include increased heart rate, elevated blood pressure, and palpitations. Neurological effects include anxiety, insomnia, tremor, and (with topiramate combination) cognitive impairment. Phentermine/topiramate is absolutely teratogenic (causes birth defects); women of childbearing potential must use strict contraception. Tell your physician about all medications, cardiovascular disease, psychiatric conditions, and any history of drug or alcohol abuse. Stop and seek care for chest pain, severe headache, palpitations, shortness of breath, or psychiatric symptoms.

Taken by mouth, once a day, in the morning. The starting prescription is 1 capsule (15 mg phentermine / 12.5 mg topiramate) each time. Your physician sets your own dose and it is printed on your label.
The pharmacy carries 2: 15 mg / 12.5 mg, 30 mg / 12.5 mg. Your physician chooses which one you get.
Phentermine, Topiramate.
30 capsules at the starting strength, shipped to your door from a licensed US pharmacy.
Yes. The law requires a live video visit with the physician before it can be prescribed.
Topiramate adds appetite suppression and metabolic support. Together, they produce more weight loss than either alone. The extended-release form also allows longer use (beyond 12 weeks) while monitoring for side effects.
Phentermine is similar to amphetamine; it stimulates the central nervous system and carries risks of dependence, cardiovascular effects, and psychiatric symptoms. Schedule IV reflects these risks. Strict medical supervision is required.
Continuous phentermine use is FDA-approved only for 12 weeks or less. After that, tolerance develops and risks increase. Your physician may pause (typically 2–4 weeks) and restart, or switch to the combination (phentermine/topiramate ER, which is approved for longer use).
