Drug & supplement interaction

Magnesium + Romosozumab-Aqqg

Romosozumab-Aqqg brand name: Evenity.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Magnesium and Romosozumab-Aqqg 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 Romosozumab-Aqqg 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

Magnesium and Romosozumab-Aqqg

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 Romosozumab-Aqqg and Magnesium 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.

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 Magnesium and Romosozumab-Aqqg 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. 2 of them are worth acting on rather than waiting out — marked below.

Bone thinning Worth acting on Additional detail
Magnesium
“Intravenously, magnesium may cause decreased skeletal muscle tone, muscle weakness, or hypocalcemic tetany.

Although magnesium is important for normal bone structure and maintenance, there is concern that very high doses of magnesium may be detrimental.”

Special populations

Magnesium in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally and appropriately. Magnesium is safe for those pregnant and breast-feeding when used in doses below the tolerable upper intake level (UL) of 350 mg daily.

Pregnancy And Lactation Possibly Safe

When prescription magnesium sulfate is given intramuscularly and intravenously prior to delivery for up to 5 days. However, due to potential adverse effects associated with intravenous and intramuscular magnesium, use during pregnancy is limited to patients with specific conditions such as severe pre-eclampsia or eclampsia. There is some evidence that intravenous magnesium can increase fetal mortality and adversely affect neurological and skeletal development. However, a more recent analysis of clinical research shows that increased risk of fetal mortality seems to occur only in the studies where antenatal magnesium is used for tocolysis and not for fetal neuroprotection or pre-eclampsia/eclampsia. Furthermore, antenatal magnesium does not seem to be associated with increased risk of necrotizing enterocolitis in preterm infants. There is also concern that magnesium increases the risk of maternal adverse events. A meta-analysis of clinical research shows that magnesium sulfate might increase the risk of maternal adverse events, especially in Hispanic mothers compared to other racial and ethnic groups.

Pregnancy And Lactation Possibly Unsafe

When used orally in excessive doses. Tell patients to avoid exceeding the tolerable upper intake level (UL) of 350 mg daily. Taking magnesium orally in higher doses can cause diarrhea. ...when prescription magnesium sulfate is given intramuscularly and intravenously prior to delivery for longer than 5 days. Maternal exposure to magnesium for longer than 5-7 days is associated with an increase in neonatal bone abnormalities such as osteopenia and fractures. The U.S. Food and Drug Administration (FDA) recommends that magnesium injection not be given for longer than 5-7 days.

How to take them

Some Romosozumab-Aqqg Products Have a Food Rule — Magnesium Should Not Break It

At least one FDA label for a product containing Romosozumab-Aqqg says to take it on an empty stomach. Most supplements — Magnesium included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Romosozumab-Aqqg on its own and move Magnesium to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Romosozumab-Aqqg 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.

Allow EVENITY to sit at room temperature for at least 30 minutes before injecting.

From the Dosage and Administration section of the FDA label we read for Romosozumab-Aqqg — 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.

Overlapping uses

What Romosozumab-Aqqg Is Prescribed For, and What Magnesium Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Romosozumab-Aqqg is a prescription medicine with approved uses on its FDA label. Magnesium is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Romosozumab-Aqqg is prescribed for: Evenity (romosozumab-aqqg) is approved to treat osteoporosis in postmenopausal women who are at high risk for breaking a bone. That includes women who have already had an osteoporotic fracture, have multiple risk factors for fractures, or have not responded to — or cannot tolerate — other osteoporosis treatments. Treatment with Evenity is limited to 12 monthly doses. If continued bone protection is needed after that course, a prescriber will typically recommend switching to a different type of osteoporosis medication called an anti-resorptive agent.

Magnesium has been studied for:

Osteoporosis Natural Medicines rates the evidence for Magnesium: Possibly Effective Read what the research shows

Magnesium for osteoporosis

Increased dietary and supplemental magnesium intake seems to increase bone mineral density and decrease bone loss in postmenopausal patients.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Romosozumab-Aqqg on your own; if you are taking Magnesium for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Magnesium

What is Magnesium?

Preventing or treating magnesium deficiency
Constipation
Muscle cramps
Sleep support
Anxiety and stress
Migraine prevention

Magnesium is an essential mineral your body needs for muscles, nerves, blood pressure, and many other functions, and supplements are useful for preventing or correcting deficiency. Some other uses, like easing constipation or preventing migraines, have reasonable support, while uses for sleep and anxiety are less proven. It is generally safe for most healthy people at recommended amounts, but talk to your pharmacist or doctor before starting, especially if you have kidney problems.

Mineral (not a plant part) · Tablets, capsules, powders, liquids, gummies, and topical Epsom salts; common forms include magnesium citrate, glycinate, oxide, chloride, malate, and aspartate

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

Magnesium: dosing

There is no single "best" dose for everyone, and the right amount depends on your age, sex, health, and the reason you are taking it. Different forms contain different amounts of actual (elemental) magnesium, which can be confusing.Do not assume more is better. There is an upper limit for magnesium taken as a supplement, and going above it raises the risk of side effects. If you are using magnesium for a specific condition like constipation or migraine, ask a health professional for guidance.

Taking Magnesium and Romosozumab-Aqqg Together: Common Questions

Is it safe to take Magnesium with Romosozumab-Aqqg?

We do not list a known interaction between Magnesium and Romosozumab-Aqqg. 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 Magnesium and Romosozumab-Aqqg have any of the same side effects?

Yes — our sources link each of them separately to 6 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 Magnesium and Romosozumab-Aqqg at the same time of day?

At least one FDA label for a product containing Romosozumab-Aqqg says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Romosozumab-Aqqg on its own and move Magnesium to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.

Are Magnesium and Romosozumab-Aqqg used for the same thing?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Magnesium in each. That is a conversation for your prescriber, especially if Romosozumab-Aqqg is being adjusted to a target.

Does Magnesium interact with any other medications?

Yes. Magnesium has 295 documented drug interactions in our database — Romosozumab-Aqqg is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
