Yaz Side Effects Center
Yaz (drospirenone and ethinyl estradiol) is an oral contraceptive used for preventing pregnancy, treating premenstrual dysphoric disorder (PMDD), and treating moderate acne in females at least 14 years of age. A generic version of Yaz is available. Common side effects of Yaz include headache, menstrual irregularities, nausea (especially when you first start taking Yaz), vomiting, bloating, stomach cramps, breast pain/tenderness/swelling, nipple discharge, fatigue, irritability, decreased sex drive (libido), changes in weight or appetite, mood changes, freckles or darkening of facial skin, increased hair growth, loss of scalp hair, problems with contact lenses, or vaginal itching or discharge. Yaz may increase the risk of blood clots, stroke, and heart attack. It can also increase blood potassium levels.
The usual dose of Yaz is one tablet daily. Nonsteroidal anti-inflammatory drugs or NSAIDs (for example, Motrin), spironolactone, potassium supplements, ACE inhibitors, and angiotensin-II receptor antagonists (ARBs) may contribute to increased potassium levels when combined with Yaz. Drugs that increase or decrease drug metabolism may decrease or increase blood levels of Yaz, respectively. There is little or no increased risk of birth defects in women who inadvertently use oral contraceptives during early pregnancy. Small amounts of the hormones in Yaz are excreted in breast-milk.

- Vascular events [see WARNINGS AND PRECAUTIONS]
- Liver disease [see WARNINGS AND PRECAUTIONS]

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Contraception and Acne Clinical Trials
The data provided reflect the experience with the use of Yaz in the adequate and well-controlled studies for contraception (N=1,056) and for moderate acne vulgaris (N=536).
For contraception, a Phase 3, multicenter, multinational, open-label study was conducted to evaluate safety and efficacy up to one year in 1,027 women aged 17 - 36 who took at least one dose of Yaz. A second Phase 3 study was a single center, open-label, active-controlled study to evaluate the effect of 7 28-day cycles of Yaz on carbohydrate metabolism, lipids and hemostasis in 29 women aged 18-35. For acne, two multicenter, double-blind, randomized, placebo-controlled studies, in 536 women aged 14-45 with moderate acne vulgaris who took at least one dose of Yaz, evaluated the safety and efficacy during up to 6 cycles.
The adverse reactions seen across the 2 indications overlapped, and are reported using the frequencies from the pooled dataset. The most common adverse reactions ( ≥ 2% of users) were: headache/migraine (6.7%), menstrual irregularities (including vaginal hemorrhage [primarily spotting] and metrorrhagia (4.7%), nausea/vomiting (4.2%), breast pain/tenderness (4%) and mood changes (mood swings, depression, depressed mood and affect lability) (2.2%).
PMDD Clinical Trials
Safety data from trials for the indication of PMDD are reported separately due to differences in study design and setting in the Contraception and Acne studies as compared to the PMDD clinical program.
Two (one parallel and one crossover designed) multicenter, double-blind, randomized, placebo-controlled trials for the secondary indication of treating the symptoms of PMDD evaluated safety and efficacy of Yaz during up to 3 cycles among 285 women aged 18-42, diagnosed with PMDD and who took at least one dose of Yaz.
Common adverse reactions ( ≥ 2% of users) were: menstrual irregularities (including vaginal hemorrhage [primarily spotting] and metrorrhagia) (24.9%), nausea (15.8%), headache (13.0%), breast tenderness (10.5%), fatigue (4.2%), irritability (2.8%), decreased libido (2.8%), increased weight (2.5%), and affect lability (2.1%).
Adverse Reactions ( ≥ 1%) Leading to Study Discontinuation
Contraception Clinical Trials
Of 1,056 women, 6.6% discontinued from the clinical trials due to an adverse reaction; the most frequent adverse reactions leading to discontinuation were headache/migraine (1.6%) and nausea/vomiting (1.0%).
Acne Clinical Trials
Of 536 women, 5.4% discontinued from the clinical trials due to an adverse reaction; the most frequent adverse reaction leading to discontinuation was menstrual irregularities (including menometrorrhagia, menorrhagia, metrorrhagia and vaginal hemorrhage) (2.2%).
PMDD Clinical Trials
Of 285 women, 11.6% discontinued from the clinical trials due to an adverse reaction; the most frequent adverse reactions leading to discontinuation were: nausea/vomiting (4.6%), menstrual irregularity (including vaginal hemorrhage, menorrhagia, menstrual disorder, menstruation irregular and metrorrhagia) (4.2%), fatigue (1.8%), breast tenderness (1.4%), depression (1.4%), headache (1.1%), and irritability (1.1%).
Serious Adverse Reactions
Contraception Clinical Trials: migraine and cervical dysplasia
Acne Clinical Trials: none reported in the clinical trials
The following adverse reactions have been identified during post approval use of Yaz. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Adverse reactions are grouped into System Organ Classes, and ordered by frequency.
Vascular disorders: Venous and arterial thromboembolic events (including pulmonary emboli, deep vein thrombosis, cerebral thrombosis, retinal thrombosis, myocardial infarction and stroke), hypertension (including hypertensive crisis)
Hepatobiliary disorders: Gallbladder disease, liver function disturbances, liver tumors
Immune system disorders: Hypersensitivity (including anaphylactic reaction)
Gastrointestinal disorders: Inflammatory bowel disease
Musculoskeletal and connective tissue disorders: Systemic lupus erythematosus
