MemoPryl and St. John's Wort: Ask This Before the First Capsule
MemoPryl and St. John's wort are linked only through a sibling pack: the herb is one of six names we cannot confirm for your bottle, and no amount is printed. St. John's wort can weaken many medicines, so read your Supplement Facts panel and ask your doctor or pharmacist before you start.

Does MemoPryl contain St. John's wort?
We cannot say for the bottle you will receive. St. John's wort is named on a sibling MemoPryl pack, and no Supplement Facts panel has been supplied for either bottle image.
The two images disagree on the label. Label A reads "Cognitive Support Formula*" with 30 capsules. Label B reads "Advanced Formula" with 60 capsules. Neither shows an ingredient line.
Next step: when the bottle arrives, read the panel. Look for "St. John's wort", "hypericum" or "Hypericum perforatum". If the panel is missing, call the desk at +1 (302) 200-3480 before taking a capsule.
Why does St. John's wort clash with medicines?
It can change how the body handles many drugs, so they work less well. NCCIH says it can weaken crucially important medicines (NCCIH, St. John's Wort safety).
It may also contribute to serotonin-related side effects when combined with some antidepressants (NCCIH, St. John's Wort safety) (MedlinePlus, Serotonin syndrome). That is why this one herb gets its own page on a memory supplement site.
| Medicine group | What can happen |
|---|---|
| Antidepressants | Weaker effect, or serotonin-related effects |
| Birth control pills | May work less well |
| Warfarin and other blood thinners | Effect may change |
| Some seizure and heart medicines | Effect may weaken |
| Some HIV and cancer drugs | Effect may weaken |
| Cyclosporine (transplant) | Effect may weaken |
Which questions should I ask my pharmacist?
Take the bottle, or a photo of the panel, to the pharmacist and ask about every medicine you use, including the ones you take rarely.
Keep taking prescribed medicine. Do not stop a drug on your own to make room for a supplement.

FAQ01
MemoPryl questions people ask
Can I take MemoPryl with antidepressants?
Ask your doctor or pharmacist first. St. John's wort, named on a sibling pack, may cause serotonin-related effects with some antidepressants (NCCIH, St. John's Wort safety). Never stop a prescription yourself, and bring the bottle's panel to the appointment.
Does MemoPryl weaken birth control pills?
We cannot confirm that for your bottle, because no panel was supplied. NCCIH lists birth control pills among medicines St. John's wort can weaken (NCCIH, St. John's Wort safety). Ask a pharmacist before you start.
What are signs of a bad reaction to St. John's wort?
Agitation, sweating, shaking and fast heartbeat can point to serotonin syndrome (MedlinePlus, Serotonin syndrome). Stop the capsules and get medical help. A rash or sun-linked skin reaction is also a reason to call.
