Calcarea Phosphorica is an over-the-counter homeopathic remedy, a highly diluted calcium phosphate (one of the Schuessler “tissue salts”), used for occasional exhaustion and weakness during recovery from illness and sold in the U.S. since about 1984. The dilution means most people notice no side effects at all, but its uses come from homeopathic tradition rather than accepted medical evidence, and the FDA has not evaluated them. If symptoms have not improved after 72 hours or get worse, stop and see a doctor, since lasting tiredness can signal low iron or another problem that needs real treatment.
Clinical pearls
- Take it about 30 minutes away from food; children six and older take the tablet crushed and dissolved in water.
- It does not supply a useful amount of calcium, so it cannot replace a calcium or vitamin D supplement for bones.
- Sensitive teeth, growing gum swelling or severe indigestion call for a dentist or doctor visit, not more of this remedy.
- Tissue salt tablets are often made on a lactose or sugar base, so check the inactive ingredients if you avoid either.

Calcarea Phosphorica on the U.S. market: products, makers and brands
How Calcarea Phosphorica appears in the FDA’s National Drug Code Directory — including its dosage forms, strengths, brand names, manufacturers, and FDA-listed product records. These are directory records, not sales or prescription volume.
The FDA lists Calcarea Phosphorica products.
Calcarea Phosphorica side effects reported to the FDA (FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Calcarea Phosphorica — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Calcarea Phosphorica in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.
