Drug & supplement interaction

Lithium + Asfotase Alfa

Asfotase Alfa brand name: Strensiq.

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 Lithium and Asfotase Alfa 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.

Interaction report

Lithium and Asfotase Alfa

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 Asfotase Alfa and Lithium 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 Lithium and Asfotase Alfa 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.

    Lithium

    “Orally, lithium can cause polyuria, polydipsia, and edema (9). Chronic lithium use has been reported to cause central or nephrogenic diabetes insipidus, hypocalciuric hypercalcemia, and nephrotic syndrome. Long-term lithium use is estimated to increase the odds of chronic kidney disease (CKD) by at least 2-fold and may contribute to CKD progression.”

Reported for Lithium but not commonly for Asfotase Alfa: a severe skin reaction, kidney problems, blood clots and memory problems.

Effects for Asfotase Alfa come from the ADVERSE REACTIONS section of its FDA label; effects for Lithium come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 9,959 voluntary FDA FAERS reports for Asfotase Alfa 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

Lithium in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When lithium carbonate and lithium citrate are used orally. Lithium can cause fetal toxicity and increases the risk for cardiac and other abnormalities, including neural tube and urethral defects. However, it does not seem to increase the risk for preterm birth or low birth rate. Some research suggests lithium might increase the risk for spontaneous abortion. Based on a meta-analysis of 2 population studies, taking lithium during pregnancy may increase the risk for spontaneous abortion when compared with the general population, but not when compared with patients with affective disorders not taking lithium during pregnancy. This suggests that it may be the presence of affective disorder itself, or the possible associated use of other teratogenic drugs or substances during pregnancy, which may increase the risk for spontaneous abortion. When the potential benefits to the mother and child outweigh the possible risk to the fetus, prescription lithium may be used with close monitoring by a healthcare professional. The safety of lithium supplements during pregnancy is unknown.

Lactation Likely Unsafe

When used orally. Lithium is secreted into breast milk and may cause adverse effects in the nursing infant. Prescription lithium may be used in circumstances when the potential maternal benefits outweigh the possible risk to the infant. The infant should be closely monitored for signs of lithium toxicity.

About Lithium

What is Lithium?

Lithium
  • Mood support
  • Bipolar disorder (prescription)
  • Healthy mental function
  • Irritability or stress
  • Sleep support

Lithium is a naturally occurring metal that, in prescription form (lithium carbonate or citrate), is an FDA-approved, well-proven treatment for bipolar disorder. Low-dose supplement forms like lithium orotate are sold for mood support, but there is very little reliable evidence that they work, and even small amounts of lithium can be risky for some people. Always talk to a pharmacist or doctor before taking any lithium product.

Mineral element (not a plant); various lithium salts · Capsules, tablets (lithium orotate, lithium aspartate in supplements; lithium carbonate and citrate as prescription drugs)

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

Lithium: dosing

There is no established, well-tested dose for low-dose lithium supplements, and product strengths vary widely between brands.

About Asfotase Alfa

What Is Asfotase Alfa Used For?

Brand name: Strensiq

Strensiq (asfotase alfa), given as a subcutaneous injection, is approved to treat perinatal/infantile-onset and juvenile-onset hypophosphatasia (HPP) — a rare genetic disorder in which the body lacks enough of an enzyme called TNSALP, leading to problems with bone mineralization, rickets, bone deformity, and muscle weakness.

HPP can present at birth or in childhood. Strensiq is the specific brand approved for these forms of the disease. Safety and effectiveness have been established in pediatric patients across both onset types.

Most-Reported Side Effects for Asfotase Alfa

From FAERS, the FDA’s public side-effect reporting system (9,959 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Injection site pain 1,327 reports
Fatigue 952 reports
Injection site erythema 869 reports

Taking Lithium and Asfotase Alfa Together: Common Questions

Is it safe to take Lithium with Asfotase Alfa?
We do not list a known interaction between Lithium and Asfotase Alfa. 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 Lithium and Asfotase Alfa 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.
Does Lithium interact with any other medications?
Yes. Lithium has 515 documented drug interactions in our database — Asfotase Alfa is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
