Your first 90 days
Your first 90 days on Tarpeyo for IgA nephropathy
What happens before the first fill, the days that matter, the label's rules and who to call, from the label, the drugmaker's own program and one insurer's written rules.
Tarpeyo has no REMS, no required blood test and no dose step, which makes it the gentlest start among the IgA nephropathy drugs on paper. What it has instead is a single pharmacy that carries it, 4 capsules that go down whole an hour before breakfast, and a steroid's warnings about grapefruit and infection. This page lays out those first 3 months from the FDA label, Calliditas's own support program and one insurer's written rules.
What has to happen before the first bottle ships
Tarpeyo has no REMS, but it is sold through one specialty pharmacy and most plans want a prior authorization. The first bottle still waits on paperwork, not on a pharmacy counter. These are the 5 things in the way, in order.
One enrollment form, signed by you and your doctor
The Tarpeyo Touchpoints enrollment form starts everything. It lets the program look for financial help you qualify for and route the prescription to PANTHERx Rare Pharmacy, the only pharmacy that dispenses Tarpeyo. Your signature is on it too, so the office cannot send it without you.Tarpeyo Touchpoints
A hepatitis B check, and a word about infections
The label says to screen for hepatitis B before starting, because a steroid can wake up an old infection. It also says to avoid Tarpeyo in anyone with active or dormant tuberculosis, an untreated fungal, bacterial or viral infection, or herpes in the eye. Certain parasites are to be ruled out in people who have spent time in the tropics. Tell the nephrologist about any of these before day 1.FDA label
The conditions a steroid can worsen
The label asks prescribers to monitor people with high blood pressure, prediabetes or diabetes, osteoporosis, stomach ulcers, glaucoma or cataracts, or a family history of diabetes or glaucoma. The Patient Information adds liver problems and any planned surgery. None of these is a ban, but each one is something the doctor wants to know going in.FDA label
Vaccines, before rather than after
The label says corticosteroids may weaken the response to some vaccines and asks prescribers to advise on vaccine timing. Calliditas points out that Tarpeyo requires no immunizations before treatment. The practical question for your doctor is whether any shot you are due for should come first.FDA label
The call from 1-833-444-8277
Once the form is in, a Tarpeyo Touchpoints Care Navigator calls from that number to set up the first delivery and email tracking. Calliditas asks patients to save the number so the call is never missed. The box ships after you confirm.Tarpeyo Touchpoints
The days that matter
Counted from the first dose, with the 30-day refills, a check on the first weeks of side effects and the taper that ends the course at month 9. Type your first-dose date and the tiles become real dates you can add to your calendar.
The tiles below count days from a first dose. Enter the date of yours, or the date you expect, and each tile becomes a real date on your calendar.
The date stays on your device. It is not sent to Trial Friend or anyone else. The calendar file works with Apple, Google and Outlook calendars.Form in, insurance checked
The enrollment form reaches Tarpeyo Touchpoints, and the program looks for financial help you qualify for while the prescriber's office submits the prior authorization. The prescriber's office supplies the biopsy and lab records the insurer asks for.
The Care Navigator calls
A call from 1-833-444-8277 to confirm your address and a delivery window. Answering it is what gets the first box moving.
First dose, four 4mg capsules
All 4 capsules at once, in the morning, at least 1 hour before a meal, swallowed whole. One bottle holds 120, a 30-day supply.
Two weeks in, the side effects that show early
Swelling of the ankles or face, higher blood pressure, acne and muscle cramps were the most common effects in the trial, and most were reversible after the course. The label asks patients to report signs of too much steroid, so this is a reasonable point to note what has changed and tell the office.
Refill, then every 30 days
A 120-capsule bottle runs out here. A Care Navigator calls before each refill, or you can sign up for text reminders, and a Touchpoints pharmacist checks in during the course.
Refill, number 2
Refill, number 3
Taper to 2 capsules a day for the last 2 weeks
The label's course is 9 months, and when treatment is stopped the dose drops to 8mg a day for the final 2 weeks. A sudden stop is what the adrenal warning is about, so this step is not optional. The label has not established the safety or benefit of a second course.
The label, revision by revision
The FDA lists which sections changed in each revision of a label. These are the revisions the current Tarpeyo label records, dated by the FDA, with a plain note on what each one meant for a patient. Older references and handouts can lag these by months.
Current label dated January 21, 2026, read from the FDA's label database today. FDA label
- January 2026
The current label carries this date. Drugs@FDA lists no new approved supplement for it, so the FDA-approved changes on record remain the ones below.FDA label
- June 2024
The infection warning was expanded after an FDA letter to the whole corticosteroid class. It added the risk of waking latent infections such as hepatitis B, tuberculosis and certain parasites, and a note on Kaposi's sarcoma. The FDA's letter says the Patient Information did not change.FDA letter
- December 2023
Full approval. The indication changed from lowering protein in the urine in people with a protein ratio of 1.5g/g or more to reducing the loss of kidney function in adults at risk of progression. That is why the Express Scripts policy on this page sets a lower protein bar than 1.5g/g.FDA label
How the label says to take it
The parts of the prescribing information and the patient leaflet that come up in the first 3 months, in plain words.
- Morning, an hour before food, all 4 at once
The label says to swallow the delayed-release capsules whole in the morning, at least 1 hour before a meal, and never to open, crush or chew them. Calliditas says the capsule is designed for targeted delivery in the gut, which is why a broken capsule is not the same medicine.FDA label
- If you miss a dose
Take the prescribed dose at the next scheduled time. The label says not to double the next dose.FDA label
- No grapefruit
Grapefruit and grapefruit juice block the enzyme that clears budesonide and can raise the amount in your blood, so the label says to avoid them for the whole course.FDA label
- Medicines that do not mix
The label says to avoid strong CYP3A4 inhibitors, naming ketoconazole, itraconazole, ritonavir, indinavir, saquinavir, erythromycin and cyclosporine. Tell the pharmacist everything you take, including supplements.FDA label
- If you need surgery or fall seriously ill
The label says people on a corticosteroid may need an extra steroid dose during surgery or other severe stress, and to watch for adrenal suppression when stopping or switching steroids. Tell any surgeon or emergency team that you take Tarpeyo.FDA label
- Chickenpox and measles
The Patient Information says to avoid contact with anyone who has chickenpox or measles and to tell your doctor right away if you are exposed. Either illness can run a severe course in someone on a steroid.FDA label
- Pregnancy and breastfeeding
The Patient Information says Tarpeyo may harm an unborn baby and to talk to your doctor if you are pregnant or planning to be. The label does not require birth control. Infants exposed to steroids before birth are watched for low adrenal function.FDA label
- Storage
Room temperature, in the tightly closed original bottle, away from moisture. The cap is child-resistant.FDA label
What the label says to act on
The symptoms the label singles out, and what it tells patients and prescribers to do about each. If any of these happen, the label's instruction is the one to follow, with your care team.
Signs of too much steroid
Acne, easy bruising, a rounder face, ankle swelling, more body or facial hair, a fat pad between the shoulders, or pink or purple stretch marks. The Patient Information says to tell your doctor about any of these. In the trial, swelling of the legs or feet occurred in 17% of patients on Tarpeyo against 5% on placebo, and high blood pressure in 12% against 3%.FDA label
Infection
Fever, feeling tired, chills, aches, pain, or nausea and vomiting. The label says a steroid can mask an infection as well as cause one, and asks prescribers to consider stopping the drug if one develops. These are a same-day call rather than a note for the next visit.FDA label
Tiredness, weakness and low blood pressure
The Patient Information lists these as signs of adrenal suppression, which can appear when the course is stopped or under stress. The label is why the last 2 weeks are tapered rather than stopped.FDA label
Why the pharmacy or the insurer says no, and what fixes it
Most first-fill delays are one of these. Knowing which one tells you who to call.
- The prescription went to a retail or other specialty pharmacyOnly PANTHERx Rare Pharmacy dispenses Tarpeyo. The enrollment form routes it there, and the prescriber's office can resend a stray prescription. This is a routing problem, not a denial.Tarpeyo Touchpoints
- Prior authorization not yet approvedThe insurer wants the criteria below documented, most often the biopsy, a protein measurement, and 90 days at the highest tolerated dose of an ACE inhibitor or ARB. The nephrologist's office supplies the records.Express Scripts policy
- The plan says you have had Tarpeyo beforePolicies approve one course of about 10 months and ask that the patient has not been treated with Tarpeyo before, because the label has not established a second course. If this is a continuation of an interrupted first course, the prescriber's records showing the dates settle it.Express Scripts policy
- A copay you cannot payCommercial insurance: the Tarpeyo Touchpoints copay program, which can bring the cost to $0 for eligible patients. The program's eligibility rules name commercial insurance only, so people on Medicare or Medicaid need other help, and our help paying page lists which charity funds are open.Tarpeyo Touchpoints
Express Scripts prior authorization policy, January 29, 2025
- Age 18 or older, with IgA nephropathy confirmed by biopsy
- Protein in the urine of 0.5g a day or more, or a urine protein-to-creatinine ratio of 0.8g/g or higher
- At least 90 days on the highest tolerated dose of an ACE inhibitor or an ARB
- At least 90 days of supportive care, meaning blood pressure control, lifestyle and heart risk measures

- Prescribed by or with a nephrologist
Approval length. 10 months in total. A patient already on Tarpeyo is approved for the months left to reach 10.
This policy was reviewed in January 2025 and lowered its protein threshold from the 2024 version. Other plans set their own thresholds and several revised them in 2025 and 2026, so yours may differ. It is here as an example of what a plan asks for, not as a rule. Express Scripts policy
Who to call, and what they can do
The drugmaker's program handles most of the first-fill problems above. Charity funds and foundation help are on the help paying page.
- A Care Navigator who looks for financial help you qualify for, schedules the first delivery and calls before each refill
- Copay assistance that can bring the cost to $0 for eligible US residents with commercial insurance, by the program's own terms
- Home delivery through PANTHERx Rare Pharmacy, with email tracking and optional text reminders for refills
- A Touchpoints pharmacist who checks in during the 9-month course to answer questions about the drug
Trial Friend takes no money from this program. Tarpeyo Touchpoints
Five questions for the pharmacist or the support line
- Will the delivery call come from 1-833-444-8277 or from PANTHERx, and what days should I expect it?
- I take my blood pressure pill in the morning too. Does the hour-before-food rule change when I take it?
- Which of my other medicines or supplements are strong CYP3A4 inhibitors?
- If I get a fever or am exposed to chickenpox, who do I call first, the nephrologist or you?
- When my last bottle comes, will it hold the 2-capsule taper, or do I use the same bottle and take fewer?
Questions people ask in the first weeks
How long does it take to get Tarpeyo after it is prescribed?
There is no fixed number. The enrollment form, the prior authorization and the delivery call each take their own time. Calliditas's own advice is to answer the call from 1-833-444-8277 so the first box is not held up.
Can I pick up Tarpeyo at my regular pharmacy?
No. Calliditas distributes it only through PANTHERx Rare Pharmacy, which delivers to your home. No other pharmacy carries it.
What if I miss a dose of Tarpeyo?
The label says to take the prescribed dose at the next scheduled time and not to double up.
Does Tarpeyo require blood tests?
The label requires no scheduled test during treatment, which Calliditas points out as a difference from some other IgAN drugs. It does ask for hepatitis B screening before the start, and your nephrologist will still check protein and kidney function to see how the drug is working.
Can I eat grapefruit on Tarpeyo?
No. The label says to avoid grapefruit and grapefruit juice for the whole course, because they raise the amount of budesonide in the blood.
Why was Tarpeyo denied by my insurance?
Most often the plan wants proof of a biopsy, a protein level above its threshold, or 90 days on an ACE inhibitor or ARB. Some also ask for confirmation that this is your first course. The nephrologist's records usually resolve it, and the office handles the appeal.
Can I take a second course of Tarpeyo?
The label says the safety and benefit of further courses have not been established, and insurer policies approve one course of about 10 months. Whether to repeat it is a conversation with your nephrologist.
