Elestrin and EstroGel are both prescription transdermal estradiol gels used for menopausal symptoms, but they differ mainly in the amount of estradiol delivered per pump and where/how much gel you apply.
| Elestrin | EstroGel | |
|---|---|---|
| Active ingredient | Estradiol | Estradiol |
| Concentration | 0.06% | 0.06% |
| Estradiol per pump | 0.52 mg | 0.75 mg |
| Gel per pump | 0.87 g | 1.25 g |
| Usual dose | 1 or 2 pumps once daily | 1 pump once daily |
| Application area | Upper arm/shoulder | Entire arm, wrist to shoulder |
| Main use | Moderate-to-severe hot flashes due to menopause | Hot flashes; also labeled for moderate-to-severe vulvar/ xxxx atrophy |
So, although both are 0.06% estradiol, one pump of Elestrin is not equivalent to one pump of EstroGel. Elestrin delivers 0.52 mg estradiol per pump, while EstroGel delivers 0.75 mg.
Another practical difference is application. Elestrin is spread over the upper arm and shoulder, whereas EstroGel is spread in a thin layer over the inside and outside of the entire arm from wrist to shoulder.
Because their pump doses and absorption instructions differ, they shouldn't automatically be substituted pump-for-pump without instructions from a prescriber or pharmacist.
