Reviralis Side Effects and Safety: Ingredient Cautions and Medicine Interactions

Quick answer

Reviralis side effects are unstudied, because no trial has tested the capsules. Safety rests on the label and on research into single ingredients. The label warns people who are pregnant, nursing, under 18, have seizures or take antidepressants, blood thinners or nerve or heart medicines. Ask a clinician or pharmacist before starting.

Written by the Reviralis label deskUpdated

The short answer01

Is Reviralis safe?

We cannot call it safe or unsafe for you. No safety study of Reviralis exists, so the facts come from the label and from research on its single names.

The label says: not for anyone under 18, and ask a healthcare provider first if you are pregnant or nursing, have a medical condition or a history of seizures, or take prescription medicine, particularly an antidepressant, a blood thinner, or a medicine for the nervous or cardiovascular system. It also says not to exceed the recommended dose, which is two capsules a day.

The vitamin and mineral lines sit well below adult upper limits. The unknowns are the 18 blend names, whose amounts are hidden.

Possible effects02

What are the side effects of Reviralis?

No side-effect list exists for the product itself. The effects below are the ones reported for single ingredients, at amounts that may differ from the blend.

Reported effects of label names, by source
Label nameWhat sources report
Green tea leaf extractRare liver injury, mostly from capsule extracts; contains caffeine (NCCIH, Green Tea)
Bacopa monnieri extractNausea and cramps (Alzheimer's Drug Discovery Foundation, Bacopa monnieri)
Licorice root extractHigher blood pressure and low potassium from glycyrrhizin (NCCIH, Licorice Root)
DMAE bitartrateHeadache, drowsiness and confusion are reported; makers warn people with seizures (EBSCO Research Starters, DMAE)
PhosphatidylserineStomach upset and trouble sleeping (Cleveland Clinic, Phosphatidylserine)
L-glutamineCase reports of liver and kidney injury at high doses (MSK About Herbs, Glutamine)
Folic acid (400 mcg)Can hide a B12 deficiency (NIH ODS, Folate)

The blend ceilings are small. Green tea can hold at most 165.3 mg of extract, and licorice at most 47.3 mg. A ceiling is not a safe-dose finding. Liver injury from green tea is not predictable by dose (NCCIH, Green Tea), and the glycyrrhizin content of the licorice is not printed.

Medicines03

Does Reviralis interact with medications?

It may, and the label itself says to ask first. Several ingredients have documented interactions, which are listed here by the medicine they touch.

Medicines and the label names that may matter
MedicineLabel names involved
Blood thinners such as warfarinVitamin E (NIH ODS, Vitamin E), bilberry (MSK About Herbs, Bilberry Fruit), licorice (MSK About Herbs, Licorice)
Blood-pressure medicine and diureticsLicorice (MSK About Herbs, Licorice), olive leaf (MSK About Herbs, Olive Leaf), grape seed (NCCIH, Grape Seed Extract)
Thyroid medicineBacopa (Alzheimer's Drug Discovery Foundation, Bacopa monnieri), chromium (NIH ODS, Chromium)
Diabetes medicineChromium (NIH ODS, Chromium), niacin (NIH ODS, Niacin), olive leaf (MSK About Herbs, Olive Leaf)
Seizure medicineVitamin B6 (NIH ODS, Vitamin B6), folic acid (NIH ODS, Folate), DMAE (EBSCO Research Starters, DMAE)
Antibiotics (quinolones, tetracyclines)Zinc (NIH ODS, Zinc), magnesium (NIH ODS, Magnesium)

For antidepressants, no cited source documents a specific interaction beyond the label warning. One source says licorice may add to MAOIs, and its clinical weight is unknown (MSK About Herbs, Licorice). Tell your pharmacist about everything you take, including any antiviral.

Quick check04

Should you ask a clinician before taking Reviralis?

Yes, if any answer below is yes. Five questions take a minute and flag the common reasons to pause.

1. Does a clinician prescribe you an antiviral (acyclovir, valacyclovir or famciclovir) for herpes?
2. Do you take an antidepressant, a blood thinner, or a medicine for your nerves, thyroid, blood pressure or heart?
3. Do you have a history of seizures, liver, kidney or heart disease, high blood pressure, or another medical condition?
4. Are you under 18, pregnant or nursing?
5. Right now, do you have sores near your eyes, a fever with a stiff neck or severe headache, or sores with confusion?
Answer all fiveYour result shows here. It is a checklist, not medical advice.

Doubling up05

Can you take Reviralis with a multivitamin?

You can, but check the totals first. Two products can add up past an adult upper limit even when each looks modest.

Reviralis already carries vitamin B6 at 12 mg, zinc at 10 mg and folic acid at 400 mcg. Type in your other product's amounts and compare each total with the limit.

Take a multivitamin or another supplement too? Type what its label prints per day for any line below. Leave the rest blank.

  1. Vitamin C125 mg from Reviralis

    6.2% of the 2,000 mg adult upper limit.

  2. Vitamin E27 mg from Reviralis

    2.7% of the 1,000 mg adult upper limit.

  3. Niacin12.5 mg from Reviralis

    35.7% of the 35 mg adult upper limit.

  4. Vitamin B612 mg from Reviralis

    12.0% of the 100 mg adult upper limit.

  5. Folic acid400 mcg from Reviralis

    40.0% of the 1,000 mcg adult upper limit.

  6. Iron1 mg from Reviralis

    2.2% of the 45 mg adult upper limit.

  7. Zinc10 mg from Reviralis

    25.0% of the 40 mg adult upper limit.

  8. Selenium50 mcg from Reviralis

    12.5% of the 400 mcg adult upper limit.

  9. Copper0.052 mg from Reviralis

    0.5% of the 10 mg adult upper limit.

Type any amounts from your other products. The bars show each total as a share of the adult upper limit.

Upper limits are the adult tolerable upper intake levels from NIH (NIH ODS, Zinc) (NIH ODS, Vitamin C) (NASEM 2019, DRI Tolerable Upper Intake Levels for Elements) (NIH ODS, Vitamin B6) (NIH ODS, Folate) (NIH ODS, Vitamin E) (NIH ODS, Niacin) (NIH ODS, Magnesium); they apply to nutrients from supplements, and a limit is a ceiling for healthy adults, not a target. A checking aid, not medical advice.

When to get care06

When should you stop Reviralis and call a doctor?

Stop and call a clinician for a rash, stomach pain, a fast heartbeat, yellow skin or eyes, or any new symptom you cannot explain. Call 911 for chest pain, trouble breathing or a seizure.

  1. Painful sores near the eyesHerpes in or near the eye can harm sight. Get care the same day.
  2. A first outbreak, or sores you are unsure aboutA clinician can confirm what it is and talk about antivirals and partner safety.
  3. Sores that do not heal in 2 to 3 weeksOr frequent outbreaks. Ask about daily suppression.
  4. A weakened immune systemOutbreaks can be longer or more severe. Tell your clinician about any outbreak.
  5. Fever, stiff neck, severe headache or confusionCall 911 or go to an emergency room.
  6. Pregnant, or a new baby with sores or feverCall a clinician or emergency care right away.

From the CDC and Mayo Clinic (CDC, About Genital Herpes) (CDC, STI Treatment Guidelines: Herpes) (Mayo Clinic, Cold Sore Symptoms and Causes). This list is not complete, and a supplement is never a reason to wait.

Report a reaction to FDA MedWatch (FDA, MedWatch). Herpes care is separate: keep any prescribed antiviral, since Reviralis is not one. See antivirals and clinician care.

FAQ07

Reviralis Safety: Questions Answered

What are the side effects of Reviralis?

No study lists them for the product. Reported effects for single names include stomach upset, nausea, headache and, rarely, liver injury from green tea extract. Stop and call a clinician for any new symptom.

Is Reviralis safe during pregnancy?

We cannot say it is. The label tells you to consult a healthcare provider if you are pregnant or nursing. Sources also flag DMAE, phosphatidylserine and licorice for pregnancy, so do not start without medical advice.

Can I take Reviralis with an antidepressant?

Ask first. The label names antidepressants as a reason to talk to your provider. No source we read documents a specific interaction, but that does not mean there is none. Your pharmacist can check your list.

Is Reviralis safe with blood thinners?

Ask your prescriber first. Vitamin E, bilberry and licorice have documented links to bleeding or warfarin effects, and the label warns about blood thinners. Do not start it without that advice.

Can Reviralis cause liver problems?

Rarely, a green tea extract has been tied to liver injury, mostly from capsules. The label ceiling for green tea is 165.3 mg of extract, but injury is not predictable by dose. Stop if you see yellow skin or dark urine.

Can I take Reviralis if I have seizures?

Not without a clinician's advice. The label names a history of seizures as a reason to ask first, and makers of DMAE warn people with epilepsy. Folic acid and vitamin B6 can also interact with seizure medicines.
