Drug & supplement interaction

Sulfur + Lovastatin

Lovastatin brand names: Mevacor, Altocor.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Sulfur and Lovastatin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Lovastatin states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Sulfur and Lovastatin

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Lovastatin and Sulfur in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Sulfur at all — not against Lovastatin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

No Interaction Found — But Data Suggests Sulfur and Lovastatin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

Reported for Sulfur but not commonly for Lovastatin: kidney problems and dry skin.

Effects for Lovastatin come from the ADVERSE REACTIONS section of its FDA label; effects for Sulfur come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 25,528 voluntary FDA FAERS reports for Lovastatin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Pregnancy And Lactation Possibly Safe

When applied topically and appropriately, short-term. Topical products containing sulfur in concentrations up to 6% have been safely applied nightly for up to 6 nights. There is insufficient reliable information available about the safety of sulfur when used orally; avoid using.

How to take them

Some Lovastatin Products Have a Food Rule — Sulfur Should Not Break It

At least one FDA label for a product containing Lovastatin says to take it with food. If you take Sulfur on an empty stomach out of habit, keep them separate — and take Lovastatin with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Lovastatin products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Lovastatin tablets USP should be given with meals.

From the Dosage and Administration section of the FDA label we read for Lovastatin — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Lovastatin

This page covers Sulfur only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Lovastatin page lists 184 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Apple (major), Beer (major), Grapefruit (major) and Siberian Cocklebur (major).

By severity: 8 major · 140 moderate · 36 minor.

From our pharmacist’s overview on the Lovastatin page

“Lovastatin (Mevacor) lowers cholesterol, and the liver clears it through an enzyme called CYP3A4, which is where most of these 184 supplements collide with it. This list deserves careful attention.”

About Sulfur

What is Sulfur?

  • Acne and oily skin
  • Rosacea
  • Seborrheic dermatitis and dandruff
  • Scabies and other skin parasites
  • Joint pain (as MSM)

Sulfur is a mineral used mainly in topical skin products for acne, rosacea, dandruff, and certain skin infections, and has a long history in dermatology. Topical sulfur is generally well tolerated but can be drying and smelly; oral sulfur supplements like MSM are taken for joint pain, though the evidence is limited. Talk with your pharmacist or doctor before starting any sulfur product.

Elemental sulfur (mineral) or sulfur-containing compounds · Topical creams, ointments, lotions, soaps, and bath products; oral MSM (methylsulfonylmethane) capsules and powders

An interaction check asks whether these two react with each other — it does not ask whether Sulfur is a good idea for someone in your situation. Here is what our Sulfur record says about it on its own.

Sulfur: dosing

There is no single standardized dose for sulfur, and the right amount depends on the product and how it is used. Topical products contain different concentrations of sulfur, so always follow the directions on the label.For oral supplements like MSM, there is no firmly established dose.

About Lovastatin

What Is Lovastatin Used For?

Brand names: Mevacor, Altocor

Lovastatin is used to lower high LDL ("bad") cholesterol and total cholesterol in people whose levels have not improved enough with diet alone. It is also used to slow the buildup of plaque in the arteries (coronary atherosclerosis) in people who already have coronary heart disease.

In adults without existing heart disease but with high cholesterol and low HDL ("good") cholesterol, lovastatin tablets are approved to reduce the risk of heart attack, unstable angina, and the need for procedures to open blocked arteries. Lovastatin tablets are also approved for adolescents aged 10–17 with a specific inherited condition called heterozygous familial hypercholesterolemia (heFH), when diet changes alone haven't been enough.

Most-Reported Side Effects for Lovastatin

From FAERS, the FDA’s public side-effect reporting system (25,528 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 1,535 reports
Nausea 1,401 reports
Diarrhea 1,275 reports
Dyspnea 1,226 reports

Taking Sulfur and Lovastatin Together: Common Questions

Is it safe to take Sulfur with Lovastatin?
We do not list a known interaction between Sulfur and Lovastatin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Sulfur and Lovastatin have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Sulfur and Lovastatin at the same time of day?
At least one FDA label for a product containing Lovastatin says to take it with food. If you take Sulfur on an empty stomach out of habit, keep them separate and take Lovastatin with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Lovastatin products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Lovastatin interact with any supplements?
Yes. Lovastatin has documented interactions with 184 supplements in our database — Sulfur is not one of them. The Lovastatin interaction page linked on this page lists every one, ranked by severity.
