Drug & supplement interaction

Strontium + Amitriptyline

Amitriptyline brand name: Elavil.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Strontium and Amitriptyline 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 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.

Strontium and Amitriptyline

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 Amitriptyline and Strontium 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.

How we checked

Why No Interaction Is Listed for Amitriptyline

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amitriptyline is filed under 15 classifications — including tricyclic antidepressants (tcas), antidepressant drugs, cytochrome p450 2c19 (cyp2c19) substrates. Strontium has documented interactions with 5 drug classes — the most serious being androgens (moderate), antacids (moderate) and estrogens (moderate) — and none of Amitriptyline’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Strontium and Amitriptyline 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.

  • A heart attack Worth acting on Additional detail

    Strontium

    “Orally, clinical research shows that strontium ranelate increases the relative risk of venous thromboembolism and pulmonary embolism by about 50% compared with placebo. The reason for this is unknown. Strontium ranelate also seems to increase the risk of myocardial infarction by about 1.6-fold in patients with osteoporosis.”

    Listed in the ADVERSE REACTIONS section of the FDA label for Amitriptyline. Read the label on DailyMed ›

Reported for Strontium but not commonly for Amitriptyline: blood clots, stomach pain, bone thinning and memory problems.

Effects for Amitriptyline come from the ADVERSE REACTIONS section of its FDA label; effects for Strontium come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 17,459 voluntary FDA FAERS reports for Amitriptyline 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.

Special populations

Strontium in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When consumed orally in food amounts. Strontium has not been linked to toxicity when consumed in dietary amounts, which are typically about 0.5 mg to 1.5 mg/day. ...when strontium chloride is used topically and appropriately as a toothpaste. Strontium chloride hexahydrate (Sensodyne-SC) is an FDA approved product.

Pregnancy And Lactation Likely Unsafe

When strontium-89 chloride is used during pregnancy or lactation. Strontium-89 chloride is a radioactive isotope which may cause fetal harm. It is FDA pregnancy risk category D; avoid using. Since strontium behaves similarly to calcium in the body, strontium-89 is likely to be excreted into breast milk; avoid using during lactation. There is insufficient reliable information about the safety of oral strontium when used in amounts exceeding typical dietary intake during pregnancy or lactation; avoid using.

About Strontium

What is Strontium?

  • Bone health and osteoporosis
  • Reducing fracture risk
  • Tooth sensitivity (in some toothpastes)
  • Supporting bone density

Strontium is a mineral that has been studied mainly for bone health and osteoporosis. The prescription form (strontium ranelate) showed benefit for fracture risk but carries serious heart-related safety concerns, while the over-the-counter supplement form (strontium citrate) has much less evidence. Talk to your doctor or pharmacist before using it, especially if you have heart disease or are at risk for blood clots.

Mineral element (not a plant) · Capsules and tablets, usually as strontium citrate or strontium ranelate (prescription in some countries)

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

Strontium: dosing

There is no firmly established dose for over-the-counter strontium supplements. Strontium and calcium compete for absorption, so they are usually taken at different times of day. Do not assume more is better, since higher amounts may increase risks.

Taking Strontium and Amitriptyline Together: Common Questions

Is it safe to take Strontium with Amitriptyline?
We do not list a known interaction between Strontium and Amitriptyline. 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 Strontium and Amitriptyline 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.
How was the Strontium and Amitriptyline combination checked?
Interactions in our licensed database are recorded against drug classes. Amitriptyline is filed under 15 classifications, and Strontium has documented interactions with 5 drug classes — none of Amitriptyline's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Strontium interact with any other medications?
Yes. Strontium has 101 documented drug interactions in our database — Amitriptyline is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Amitriptyline interact with any supplements?
Yes. Amitriptyline has documented interactions with 296 supplements in our database — Strontium is not one of them. The Amitriptyline interaction page linked on this page lists every one, ranked by severity.
