The Side Effects of Yaz Birth Control

If you have ever watched a drug commercial, you know that almost every drug comes with a variety of side-effects, from minor to severe. Oral contraceptives like Yaz also come with a variety of side-effects that you should be aware of.

It is important to note that just because a drug lists possible side-effects there is no guarantee that you will experience them. Understanding your drug’s side-effects will not only help you decide whether or not it is safe to take the medication, it will also help you know when to contact your physician for further instructions.

What Is Yaz?

Yaz is a prescription, low-dose oral contraceptive that prevents pregnancy and eliminates mild acne. In addition, it shortens your periods and lightens your menstrual flow. It also lowers your risk of ovarian and endometrial cancer. Yazcontains small doses of artificial hormones: progestin and estrogen and it is the only oral contraceptive on the market that claims to effectively treat premenstrual dysphonic disorder (PMDD), a condition that causes bloating, gastrointestinal upset, headaches and migraines, depression, mood swings, anxiety, irritability and/or intense anger.

What Are The Side Effects of Yaz ?

Side-effects have been reported with Yaz usage. Some of these side-effects include a reduced sex drive, headaches, increased appetite, mid-cycle menstrual spotting, breakthrough bleeding, increased vaginal discharge, nausea, vomiting, gastrointestinal upset, chronic yeast infections and/or unexplained weight gain.

Most of these side-effects will diminish with continued use, but if you experience leg cramps, edema in your legs or feet, severe chest pains, breathing difficulties, depression, lumps in your breasts, migraines, blood clots and/or changes in your vision, you should seek immediate medical care. These symptoms may indicate a blood clot in your lungs or legs and/or an allergic reaction.

Will Yaz Cause Me To Gain Weight?

It is unknown whether or not Yaz will cause you to gain weight. Although it is common to experience some weight gain with oral contraceptive use, it is possible to experience weight loss or no weight gain when using Yaz.

Current studies suggest that most women experience weight gain while taking oral contraceptives, but this does not hold true for all women. If you experience significant or unexplained weight gain or weight loss while on Yaz, contact your physician for further instructions on whether or not to continue the medication.

What Should I Do If I Forget To Take A Pill?

If you forget to take a pill, do not worry – just take the pill as soon as you remember. After you have taken the pill you missed, take the next pill at your normal time, even if it means you taking two pills that day instead of one. It is important to take your pills at the same time each day.

If you take your pill at a different time each day or you consistently forget to take your pill, it can increase your risk of pregnancy and side-effects. Missing one pill normally does not cause noticeable side-effects or an unwanted pregnancy, but in order to be safe, you should use an alternative type of birth control for the next few days.
