Citracal: Side Effects, Benefits & What to Expect

Citracal is an over-the-counter supplement containing calcium citrate and vitamin D. Postmenopausal women commonly want extra calcium in their diets to treat or prevent osteoporosis, and many pregnant and breastfeeding women do also, to be sure they are getting enough. Side effects are generally minor.

Common Side Effect

• The most common side effect associated with Citracal is constipation. This can become chronic in people taking Citracal on a long-term basis.

Other Side Effects

• Other side effects can include decreased appetite, nausea and vomiting, headache, dry mouth, unusual or unpleasant taste, increased thirst and increased urination. Lowering the dosage can help.

Precaution

• People who have had kidney stones may need to avoid Citracal, because excess calcium can be a cause. These individuals should consult with a doctor before taking calcium supplements.

Drug Interactions

• Calcium supplements can interfere with the absorption of other medications such as tetracycline antibiotics, digoxin, and heart and blood pressure medications.

Allergic Reaction

• Rarely, people can have an allergic reaction to Citracal. Symptoms include difficulty breathing or swallowing, throat closing, facial or tongue swelling, and a rash or hives.
