What the statute actually says
Texas Occupations Code section 169.003 governs what a low-THC prescription can contain. It says a prescription may only provide for a 90-day supply based on the dosage prescribed to the patient, and may provide up to four refills of a 90-day supply. It also allows a physician to prescribe more than one package in a 90-day period.
What the statute does not do is set an expiration date, and it imposes no mandatory re-evaluation schedule. That is worth sitting with, because essentially every article you will read on this subject says a Texas prescription is good for one year and must be renewed annually. That advice is imported wholesale from states that issue a card with an expiry printed on it. Texas does not issue a card, and its statute does not contain the rule those articles are describing.
What is true is that the prescribing physician sets a follow-up interval as a clinical matter, most clinics work on a roughly twelve-month cycle, and most of them sell a "renewal" priced accordingly. So the practical answer and the statutory answer land in similar places. They are not the same thing, and the difference matters the moment your circumstances are not typical.
The refill clock, which nobody warns you about
One initial 90-day supply plus four refills is five fills in total. At a steady dose that comfortably outlasts a year, which is why the refill limit is invisible to most patients and why nobody writes about it. It stops being invisible in three situations.
- Your dose went up. A 90-day supply is defined by the dosage on the prescription, so a higher dose means the same fill covers the same 90 days but you may be back for a new prescription sooner if the physician rewrites it.
- You ordered ahead. Patients who consolidate orders to clear a free-delivery threshold, or who stock up before hurricane season, move through fills faster than the calendar suggests.
- Your physician wrote more than one package in a period. The statute permits it, and it draws down what you have left.
None of this is a problem if you know the number. Ask the dispensary how many fills remain the next time you place an order, because they can see your registry entry and you cannot. It takes one question and it is the only way to know which clock is going to run out first.
What a lapse actually costs
Less than patients fear, and more than it should. There is no penalty, no state paperwork, no waiting period, and nothing on your record. Your CURT entry stops supporting new fills and a physician has to evaluate you again before it resumes. If you were expecting a punishment, there isn't one.
The real cost is the gap. However long it takes to notice, book, complete a video visit, and have the new prescription entered is time you are without medicine, and for a patient managing seizures, spasticity, or pain that has been stable for months, that is not a neutral week. The second cost is money: some services charge renewal pricing only if you are continuous and full new-patient pricing if you have lapsed. Ask which before you let one run out.
When to book
Book the renewal visit when you place what you believe is your last fill, not when an order fails. There is no rule against being re-evaluated while refills remain, early renewal is routine, and doing it that way removes the gap entirely rather than shortening it. If you are not sure which fill is your last, that is the question to ask the dispensary described above.
What renewal costs across the services
Checked against each provider's own site on 2026-10-16, the annual cost across the services we compare runs from $45 at Quick Med Cards, which quotes a range rather than a price, and $98 at NuggMD up to $199 at Veriheal. The detail that matters for renewal is what happens in between: Leafwell charges $99 for a renewal as well as a new patient, so there is no second-year discount to wait for. Zen Cannabis Clinic is $150 flat for the year and bills nothing for refill requests. Texas Cannabis Clinic is $160 for twelve months but charges $75 for an extra visit in between, which matters if your dose is still moving.
The buying lesson is the one nobody applies at the time: compare year two, not year one. This is an annual expense for as long as you stay in the program, and a service that wins on the first visit while charging full price every year afterward is more expensive than it looks.
