MemoPryl and Medicines: Interaction Guide
Ask your doctor or pharmacist before you take MemoPryl with any medicine. Two ingredients named on a sibling pack matter most: St. John's wort can make many medicines weaker, and ginkgo may raise bleeding risk. The bottle you receive may differ, so read it. Keep taking prescribed medicine exactly as directed.

Is MemoPryl safe to take with other medicines?
It can be, but only after a doctor or pharmacist checks your list. Two of the six names tied to MemoPryl carry well-known interaction risks, and no warning text is printed on any image we have.
The six names come from a sibling pack and are unconfirmed for your bottle. If your bottle lists St. John's wort or ginkgo, treat the rows below as live. If it lists neither, read what it does list.
The simple rule: bring the bottle and your medicine list to the pharmacy counter before the first capsule.
Do not stop, skip or change a prescription because of a supplement. Ask first.
How does St. John's wort interact with medicines?
St. John's wort can weaken the effects of many medicines, including some that are crucial (NCCIH, St. John's Wort safety). That list covers antidepressants, birth control pills, warfarin, cyclosporine, some seizure drugs, some heart medicines, some HIV and cancer drugs and certain statins.
It can also add to serotonin-raising drugs. Together they may cause serotonin syndrome, which can be deadly if untreated (MedlinePlus, Serotonin syndrome). Symptoms include agitation, diarrhea, a fast heartbeat, hallucinations and fever.
Memorial Sloan Kettering advises stopping it at least a week before surgery or chemotherapy (MSK, St. John's Wort). It may be unsafe in pregnancy (NCCIH, St. John's Wort safety).
Does ginkgo interact with blood thinners?
Yes, it may. Ginkgo can thin the blood, and so can warfarin, aspirin and vitamin E. Taking them together may raise the risk of internal bleeding or stroke (FDA, Mixing Meds and Supplements).
Case reports include spontaneous bleeding, and seizures in people with a history or on drugs that lower the seizure threshold (MSK, Ginkgo). NCCIH notes the bleeding risk in people on anticoagulants (NCCIH, Ginkgo).
Clinicians may ask you to stop supplements two to three weeks before a procedure (FDA, Mixing Meds and Supplements). Tell your surgeon, dentist and anesthesia team.
Which medicines need a pharmacist check?
The table groups medicines by the concern a named ingredient raises. It is a prompt for your pharmacist, not a full list, and a missing medicine is not a clearance.
| Medicine type | Ingredient | Concern |
|---|---|---|
| Antidepressants (SSRIs and others) | St. John's wort | Weaker effect; serotonin syndrome (NCCIH, St. John's Wort safety) (MedlinePlus, Serotonin syndrome) |
| Birth control pills | St. John's wort | Weaker effect (NCCIH, St. John's Wort safety) |
| Warfarin, aspirin, other blood thinners | Ginkgo, St. John's wort | Bleeding risk; changed blood-thinner effect (FDA, Mixing Meds and Supplements) (NCCIH, St. John's Wort in depth) |
| HIV, transplant, heart, seizure drugs | St. John's wort | Lower drug levels (NCCIH, St. John's Wort safety) (FDA, Mixing Meds and Supplements) |
| Seizure medicines | Ginkgo, carnitine | Seizure risk in some people; carnitine levels fall with valproic acid and phenytoin (MSK, Ginkgo) (NIH ODS, Carnitine) |
| Anticholinergic drugs, thyroid medicine | Phosphatidylserine, bacopa | Possible reduced effect or cautions (Cleveland Clinic, Phosphatidyl.) (StatPearls, Bacopa monnieri) |
| Lactulose | L-glutamine | May reduce the ammonia-lowering effect (MSK, Glutamine) |

See packsWhat should you ask your pharmacist?
Ask three things: does any name on my bottle interact with my medicines, should I stop it before a procedure, and which symptoms mean I should call. Bring the bottle, not a photo of a website.

Stop the supplement and get medical advice. Call emergency services for severe symptoms such as stroke-like signs, heavy bleeding, a seizure or high fever with agitation.
For serious reactions, FDA asks you to submit a report through its Safety Reporting Portal (FDA, Report a Supplement Problem). Do not stop a prescribed medicine on your own while you wait for advice (MedlinePlus, Serotonin syndrome).

FAQ01
MemoPryl and medicines: common questions
Can I take MemoPryl with antidepressants?
Only after your doctor or pharmacist says so. St. John's wort, one name tied to MemoPryl, can weaken antidepressants and may cause serotonin syndrome when combined with some of them. Never stop your antidepressant on your own.
Does MemoPryl affect birth control pills?
It might, if your bottle holds St. John's wort. NCCIH lists birth control pills among medicines that herb can weaken. Ask a pharmacist about backup methods before starting. Check your own bottle for the ingredient list.
Is MemoPryl safe with blood thinners like warfarin?
Ask first. Ginkgo may raise bleeding risk, and St. John's wort can change how warfarin works. Both are tied to a sibling MemoPryl pack. Never change a blood thinner dose without your prescriber.
Should I stop MemoPryl before surgery?
Tell your surgeon before the date. FDA notes clinicians may ask you to stop supplements two to three weeks before a procedure, and MSK advises stopping St. John's wort at least a week before. Follow your care team's plan.
Can MemoPryl cause serotonin syndrome?
It could contribute if it contains St. John's wort and you take another serotonin-raising medicine. Symptoms include agitation, fast heartbeat and fever. Get care right away and do not stop your medicine on your own.
Does MemoPryl interact with aspirin or vitamin E?
Possibly. Ginkgo, aspirin and vitamin E can each thin the blood, and taking them together may raise bleeding risk, FDA says. Tell your pharmacist about all three before you start.
What if my MemoPryl bottle lists different ingredients?
Then judge the bottle, not the sibling pack. The six names are unconfirmed for your capsules. Read every ingredient on the panel with a pharmacist, and ask the order desk if there is no panel.
