Deplin 15 (L-methylfolate, as levomefolate calcium 15 mg, with Algae-S powder) is a capsule dispensed by prescription for the clinical dietary management of people with depression or schizophrenia who have suboptimal folate levels, used under a doctor's supervision alongside their antidepressant or antipsychotic. Because Deplin is regulated as a medical food rather than an FDA-approved drug, it is frequently excluded from prescription drug benefits, so many people are quoted a cash price at the counter. Enter your ZIP code above to see today's price at pharmacies in your area, and compare it with L-methylfolate 15 mg equivalents.
What is Deplin 15 and how does it work?
Deplin 15 is a prescription medical food from Alfasigma USA. It is not an antidepressant, not an antipsychotic, and not an FDA-approved drug, so it has no FDA-approved indications and no FDA drug label. It is intended for the clinical dietary management of patients with depression or schizophrenia who have suboptimal folate levels, and it is meant to be used under a physician's supervision in addition to the medication a person is already taking, never as a replacement for it.
Each Deplin 15 capsule supplies 15 mg of L-methylfolate (levomefolate calcium, the Metafolin form) plus Algae-S powder from Schizochytrium. L-methylfolate is the already-active form of folate, vitamin B9, and it is the form that crosses the blood-brain barrier. In the brain, folate supports the production of the neurotransmitters serotonin, norepinephrine, and dopamine. Some people, including those with certain MTHFR gene variants, convert ordinary folic acid to the active form less efficiently, which is why a clinician may choose the pre-activated form.
Deplin 15 comes as a capsule; there is no tablet form of the current product. The labeled usual adult dose is one Deplin 15 capsule, or one to two Deplin 7.5 capsules, taken daily with or without food, or as directed under medical supervision. The product is labeled for adults and children 12 years of age and older. Your prescriber decides whether Deplin is appropriate for you and at what strength.
Deplin 15 cost: manufacturer program vs. an Rx.com cash coupon
Deplin is a medical food, and medical foods are frequently excluded from prescription drug benefits. Plans that do cover it often place it on a high tier or require paperwork, so a lot of patients are quoted a full cash price at the counter.
Alfasigma, the manufacturer, does not run a traditional copay card. Instead, it makes Deplin available through a direct-purchase pharmacy program, Brand Direct Health, which fills the prescription in a 90-day supply and ships it to you. The manufacturer describes this route as open regardless of your insurance status, so being uninsured or on Medicare, Medicaid, or another government plan does not by itself shut you out of it. Your prescriber sends the prescription to that pharmacy rather than to your local one. Terms, eligibility, and the current price are set by the manufacturer and its pharmacy partner and can change, so check the conditions on the manufacturer's own Deplin site before you commit.
An Rx.com coupon is a different route. It is a cash-price discount you take to a retail pharmacy, not insurance, so it can be used if you are uninsured, if you are on Medicare or Medicaid and paying cash, or if you would rather pick the prescription up locally than wait on a mail shipment. You cannot combine a cash coupon with your insurance on the same fill. The practical move is to compare all three, what your plan charges, what the manufacturer's direct program charges, and what the cash coupon price is at pharmacies near you, and pay whichever is lowest. Prices for the same prescription can vary from one pharmacy to the next, so it is worth checking more than one. Enter your ZIP code above to compare today's price at nearby pharmacies.
L-methylfolate alternatives and other Deplin products
Ask your prescriber and pharmacist about other L-methylfolate 15 mg products. Because Deplin is a medical food rather than an approved drug, these equivalents are not Orange Book generics and are not automatically substitutable the way a true generic drug is, so the pharmacy usually needs the prescriber to authorize the change. Prices for both the brand and the alternatives vary by pharmacy, so compare them on Rx.com before you fill.
- Deplin 7.5 is the same active ingredient at half the strength. The label allows one to two Deplin 7.5 capsules daily, so a clinician may start there or step down to it.
- Deplin FC is the "free & clear" formulation from the same manufacturer, available in 7.5 mg and 15 mg capsules. It is L-methylfolate calcium without the Algae-S powder blend, and it is formulated to be free of major allergens, including milk and soy, as well as dyes and titanium dioxide. If you are allergic or sensitive to milk or soy, Deplin FC is the version to ask your prescriber about, because Deplin 15 contains both.
- Cerefolin Brain Wellness, formerly sold as CerefolinNAC, is a different prescription medical food from the same manufacturer. It combines L-methylfolate with other ingredients and is intended for a different purpose, so it is not a substitute for Deplin 15.
- Folic acid is the non-activated form of vitamin B9. It is not interchangeable with L-methylfolate, and switching to it on your own is not a substitute for what your prescriber ordered.
Which of these is right for you is a decision for your clinician, not a price question alone.
Deplin 15 safety: what to know
Deplin does not carry an FDA boxed warning, because medical foods are not FDA-approved drugs and do not carry boxed warnings. That is not the same as saying there is nothing to watch for. The most important points to raise with your clinician:
- Deplin 15 contains milk and soy. The Algae-S powder blend in the capsule includes sodium caseinate (a milk protein) and soy protein, and the product carries a "Contains Milk and Soy" allergen statement. Deplin is contraindicated in anyone with known hypersensitivity to any component of the product. If you have a milk or soy allergy, tell your prescriber and pharmacist before you fill it, and ask about Deplin FC, the free-and-clear formulation made without the algal powder blend and without milk or soy.
- Allergic reactions are the adverse effect reported with oral L-methylfolate. Get medical help right away if you develop hives, swelling of the face, lips, tongue, or throat, or trouble breathing after a dose.
- It is not a folic acid substitute. L-methylfolate and folic acid are not interchangeable.
- Vitamin B12 matters. Folate can correct the anemia caused by a B12 deficiency while nerve damage from that deficiency quietly continues. If you are at risk for low B12, ask to be checked before and during treatment.
- It does not replace your antidepressant or antipsychotic. It is meant to be used alongside them, under supervision. Do not stop a prescribed medication on your own.
- Interactions. Folate can interact with anticonvulsants such as phenytoin, phenobarbital, carbamazepine, and primidone, and with methotrexate, pyrimethamine, capecitabine or 5-FU, and sulfasalazine. Give your pharmacist your full medication list.
Deplin is labeled for use in adults and children 12 years of age and older, under medical supervision. If you are pregnant or nursing, discuss it with your clinician first.
