Lifestyle & Tips
- Apply a thin layer to affected areas only, once daily, as directed by your doctor.

Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the allergic reaction you experienced, including any symptoms that occurred.
If you have elevated calcium levels in your blood.
If you currently have a skin infection.
If the skin where you will be applying this medication is thinning.
This list is not exhaustive, and it is crucial to discuss all your medications (including prescription, over-the-counter, natural products, and vitamins) and health conditions with your doctor and pharmacist. They will help determine if it is safe to take this medication with your other medications and health conditions. Never start, stop, or adjust the dosage of any medication without first consulting your doctor.
Precautions & Cautions
Before using any other medications or skin products, including soaps, consult with your doctor to ensure safe use. If you are undergoing light therapy, notify your doctor to avoid any potential interactions.
When applying this medication, avoid putting it on cuts, scrapes, or damaged skin. Exercise caution when applying it to large areas of skin or near open wounds, and consult with your doctor if you have any concerns.
To minimize the risk of severe side effects, use this medication only as directed by your doctor. Do not exceed the recommended dosage, frequency, or duration of treatment, as this may increase the likelihood of adverse reactions.
You may be more susceptible to sunburn while using this medication. To protect yourself, avoid exposure to sunlight, sunlamps, and tanning beds, and use sunscreen and protective clothing and eyewear when outdoors.
Prolonged use of this medication may increase the risk of developing cataracts or glaucoma. Discuss this potential risk with your doctor and monitor your eye health accordingly.
When using this medication in children, exercise caution, as the risk of certain side effects may be higher in this population. In some cases, this medication may affect growth in children and teenagers, and regular growth checks may be necessary. Consult with your doctor to discuss the potential risks and benefits.
If you are pregnant, planning to become pregnant, or breastfeeding, inform your doctor to discuss the potential benefits and risks to you and your baby. When breastfeeding, avoid applying this medication directly to the nipple or surrounding area to prevent potential harm to your baby.
Overdose Information
Overdose Symptoms:
- Excessive use may lead to systemic corticosteroid effects (e.g., Cushing's syndrome, adrenal suppression) or hypercalcemia (due to calcipotriene).
- Symptoms of hypercalcemia include nausea, vomiting, constipation, muscle weakness, fatigue, confusion, and increased urination.
What to Do:
If you suspect an overdose or experience severe side effects, seek immediate medical attention. Call your doctor or poison control center (1-800-222-1222). Treatment is symptomatic and supportive. Discontinue the medication and monitor serum calcium and HPA axis function.
Drug Interactions
Moderate Interactions
- Other topical corticosteroids (increased risk of systemic effects)
- Other vitamin D analogs (increased risk of hypercalcemia)
Monitoring
Baseline Monitoring
Rationale: To establish baseline for efficacy assessment.
Timing: Prior to initiation of therapy.
Rationale: To identify pre-existing skin damage that may affect absorption or increase risk of adverse effects.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Weekly or as clinically indicated during treatment period.
Target: Improvement in psoriasis symptoms.
Action Threshold: Lack of improvement or worsening of condition may require re-evaluation of diagnosis or treatment.
Frequency: At each follow-up visit.
Target: Minimal to no local reactions.
Action Threshold: Severe or persistent reactions may necessitate discontinuation or dose adjustment.
Frequency: Periodically, especially with extensive use, prolonged treatment, or occlusive dressings.
Target: Normal HPA axis function, normal blood glucose.
Action Threshold: Any signs of systemic absorption warrant immediate medical evaluation and potential discontinuation.
Frequency: Rarely needed, but consider if exceeding recommended dose or surface area.
Target: Normal serum calcium levels.
Action Threshold: Symptoms of hypercalcemia or elevated serum calcium levels require immediate medical attention.
Symptom Monitoring

- Burning
- Itching
- Erythema
- Folliculitis
- Skin atrophy
- Striae
- Telangiectasias
- Acneiform eruptions
- Perioral dermatitis
- Secondary infection

Special Patient Groups
Pregnancy
Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Animal studies have shown teratogenic effects with high doses of both calcipotriene and betamethasone. This medication should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
It is not known whether calcipotriene or betamethasone are excreted in human milk following topical application. Systemic absorption is low, but caution should be exercised when administered to a nursing woman. Avoid applying to the breast area to prevent infant ingestion.
Pediatric Use
Safety and effectiveness in pediatric patients under 12 years of age have not been established. Children may be more susceptible to systemic toxicity from topical corticosteroids due to a larger skin surface area to body weight ratio and immature skin barrier. Adrenal suppression and Cushing's syndrome have been reported in children receiving topical corticosteroids. Use with caution and for the shortest duration possible in adolescents 12 years and older.
Geriatric Use
No overall differences in safety or effectiveness were observed between elderly subjects and younger subjects. However, elderly patients may have thinner skin and be more susceptible to skin atrophy and other local side effects. Use with caution and monitor for adverse reactions.
Clinical Information
Clinical Pearls
- This combination product is highly effective for plaque psoriasis but should be used judiciously due to the potent corticosteroid component.
- Advise patients to apply a thin layer only to affected areas and to wash hands thoroughly after application to avoid accidental transfer to sensitive areas like the face or eyes.
- Emphasize the importance of not exceeding the recommended dose (60g/week) or duration (4 weeks) to minimize the risk of systemic side effects (HPA axis suppression, hypercalcemia).
- Educate patients about signs of skin atrophy (thinning, bruising, stretch marks) and systemic effects, and to report them promptly.
- Consider alternative or rotational therapies for long-term management to reduce cumulative corticosteroid exposure.
Alternative Therapies
- Topical corticosteroids (e.g., clobetasol, fluocinonide)
- Topical vitamin D analogs (e.g., calcipotriene, calcitriol)
- Topical retinoids (e.g., tazarotene)
- Topical calcineurin inhibitors (e.g., tacrolimus, pimecrolimus - off-label for psoriasis)
- Coal tar
- Anthralin
- Phototherapy (UVB, PUVA)
- Systemic therapies for severe psoriasis (e.g., methotrexate, cyclosporine, biologics, oral retinoids, apremilast)
