What are the side effects of taking progesterone tablets?

For women planning pregnancy, menstrual irregularities are common. When visiting a hospital for evaluation, insufficient luteal function is often identified as the underlying cause—prompting physicians to prescribe progesterone tablets. These medications are highly effective in treating such conditions and can significantly improve fertility outcomes. However, potential side effects must be carefully monitored. So, what are the possible side effects of taking progesterone tablets? Below, we address this question.

What Side Effects Can Occur with Progesterone Tablet Use?

Generally, progesterone tablets are primarily used to treat endometriosis—including adenomyosis and endometriomas (“chocolate cysts”)—as well as menstrual disorders and dysmenorrhea. However, their use may disrupt endocrine balance and commonly cause gastrointestinal discomfort, such as nausea and vomiting. Prolonged or excessive dosing may lead to endometrial atrophy or ovarian atrophy, potentially resulting in amenorrhea or markedly reduced menstrual flow. Therefore, before initiating therapy, hormonal profiling (e.g., sex hormone assays) is recommended to guide targeted treatment. Dosage must always be determined by a physician based on individual clinical assessment; self-medication should be strictly avoided to prevent adverse effects.

Knowledge Expansion: Therapeutic Roles of Dydrogesterone Tablets

1. Management of Threatened Abortion

Dydrogesterone tablets have broad clinical applications, particularly in conditions associated with progesterone deficiency. Low endogenous progesterone levels may predispose women to recurrent miscarriage, infertility, or abnormal uterine bleeding—all of which pose significant health risks. Timely supplementation with dydrogesterone can effectively alleviate these complications. Moreover, dydrogesterone is indicated for uterine bleeding secondary to luteal phase insufficiency; bleeding typically ceases during treatment, and upon discontinuation, the endometrium sheds normally.

2. Treatment of Secondary Amenorrhea

In cases of secondary amenorrhea, dydrogesterone administration induces transformation of the endometrium from the proliferative to the secretory phase. Withdrawal bleeding typically occurs following cessation of therapy. When endogenous progesterone levels are inadequate, dydrogesterone provides effective hormonal supplementation. Similarly, in early pregnancy complicated by low progesterone levels, dydrogesterone supplementation supports optimal fetal development.

The above outlines the potential side effects associated with progesterone tablet use. We hope this information proves helpful to you.
