Summary
estradiol

Iclevia is a birth control pill. It contains two hormones, a progestin and an estrogen, that work together to prevent pregnancy.

tacrolimus topical

Tacrolimus extended-release capsules help prevent organ rejection in kidney transplant patients. It works by suppressing your immune system.

What It Treats
estradiol

Iclevia is used by women who can get pregnant to prevent pregnancy. It contains two types of hormones. These hormones stop you from releasing an egg and also change the lining of your uterus, which prevents pregnancy.

tacrolimus topical

This medicine is used to prevent your body from rejecting a new kidney after a transplant. It is for adult patients who can swallow capsules whole. You will take it with other medicines that also suppress your immune system.

How It Works
estradiol

Iclevia contains two hormones: levonorgestrel (a progestin) and ethinyl estradiol (an estrogen). These hormones prevent pregnancy by stopping ovulation (the release of an egg from the ovary). They also change the lining of the uterus to prevent a fertilized egg from implanting.

tacrolimus topical

Tacrolimus belongs to a class of drugs called calcineurin inhibitors. It lowers the activity of your immune system. This helps prevent your body from attacking your new kidney.

Cigarette smoking increases your risk of serious heart problems from birth control pills. This risk is higher if you are over 35 and smoke more cigarettes. You should not take Iclevia if you are over 35 and smoke.

tacrolimus topical

This medicine can increase your risk of serious infections and certain cancers. These problems could lead to hospitalization or even death. This drug is not approved for liver transplants and may increase the risk of death in female liver transplant patients.

Pregnancy
estradiol

Do not use Iclevia if you are pregnant. If you become pregnant while taking Iclevia, stop taking it right away. Iclevia can reduce milk production, so you may want to use a different birth control method while breastfeeding.

estradiol is classified in the Estrogen Hormone drug class, while tacrolimus topical sits within the Calcineurin Inhibitor (Topical) class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.

Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, estradiol has 22,953 submissions while tacrolimus topical has 0. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known moderate interaction flagged in FDA labeling, attributed to estradiol can slow down how your body breaks down tacrolimus, which may increase the amount of medicine in your blood to unsafe levels.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.

A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
