Compounded ketotifen capsules are a powerful mast cell stabilizer and antihistamine commonly used to manage mast cell activation syndrome (MCAS), allergic inflammation, and histamine-related disorders. Ketotifen works by blocking histamine receptors and preventing mast cell degranulation, helping reduce symptoms like hives, brain fog, flushing, and gastrointestinal discomfort. While not commercially available in capsule form in the U.S., ketotifen is a trusted therapy in functional and integrative medicine, especially for patients with chronic allergies, POTS, or Ehlers-Danlos syndrome. Our pharmacy compounds ketotifen in custom strengths, preservative-free, and filler-free formulations to support precise dosing and enhanced tolerability for sensitive individuals.
Prescribers choose compounded ketotifen for mast cell and allergic conditions, tailoring the strength to each patient. We compound each capsule to the exact strength your prescriber specifies, made to order in our pharmacy.
This is a compounded medication prepared to your prescription and used under a prescriber's guidance. Your prescriber will set the dose and schedule and monitor your response. Every batch is pharmacist-compounded, quality-verified, and shipped nationwide. Prescription required.
Frequently asked questions
What does ketotifen treat?
MCAS, chronic hives, and allergic conditions — it both blocks histamine and stabilizes the mast cells that release it.
Why is it compounded?
Oral ketotifen isn't commercially available in the U.S., so compounding is how patients here can access it at the right dose.
How is it different from a regular antihistamine?
It adds mast cell stabilization to antihistamine action, offering broader relief for mast cell-driven symptoms.
Is it monitored?
Yes — your prescriber sets the dose and schedule and monitors your response.
Do I need a prescription?
Yes. Ketotifen capsules are compounded to your prescriber's order and require a valid prescription. Our pharmacists prepare and verify every batch.

Request Prescribing AccessCompounded Ketotifen capsules combine two useful actions in one medication — an antihistamine and a mast cell stabilizer — making them valuable for mast cell activation syndrome (MCAS), chronic hives, allergic conditions, and related symptoms. Ketotifen blocks histamine while also calming the mast cells that release it, providing broader relief than a standard antihistamine alone. Because oral ketotifen isn't commercially available in the U.S., compounding is how patients here can access this helpful medication at the dose they need.
