Mercilon 28 (Desogestrel 0.15 mg + Ethinylestradiol 0.02 mg) is a low-dose combined oral contraceptive pill used to prevent pregnancy. It contains 28 tablets per pack (21 active + 7 reminder pills) and is taken once daily to provide reliable birth control when used correctly.

Looking for a Gentle, Low-Dose Birth Control Option?

Choosing the right contraceptive can feel overwhelming. There are so many brands, so many hormone combinations, and honestly — so much conflicting advice online.

That’s where Mercilon 28 stands out. It’s a low-estrogen combined pill, designed to be effective yet gentle for many women. If you want dependable protection with a predictable cycle, this might be the option your healthcare provider suggests.

Let’s break it down in simple terms so you know exactly what you’re taking and why.



What’s Inside Mercilon 28?

Each active tablet contains:

  • Desogestrel 0.15 mg (a progestin hormone)

  • Ethinylestradiol 0.02 mg (a synthetic estrogen)

The pack includes:

  • 21 active hormone tablets

  • 7 inactive (placebo/reminder) tablets

These two hormones work together to prevent pregnancy in three smart ways:

  1. Stop ovulation (no egg released)

  2. Thicken cervical mucus (harder for sperm to travel)

  3. Change the uterine lining (less likely for implantation)

It’s a triple-layer protection system. Simple, but effective.

What Is Mercilon 28 Used For?

Primarily, Mercilon 28 is used for:

  • ✔ Preventing pregnancy

  • ✔ Regulating irregular menstrual cycles

  • ✔ Reducing heavy menstrual bleeding

  • ✔ Improving period pain

  • ✔ Helping with mild acne (in some cases)

Doctors sometimes prescribe it for hormonal balance issues as well. However, it’s not meant to protect against sexually transmitted infections (STIs).

How to Take Mercilon 28 (Dosage Guide)

Consistency is everything here.

  • Take one tablet daily at the same time

  • Start on Day 1 of your period (recommended) or as directed by your doctor

  • After finishing 21 active pills, continue with the 7 reminder tablets

  • You’ll usually have a withdrawal bleed during the placebo week

  • Start the next pack immediately after finishing the current one

Missed a pill?

  • If less than 12 hours late: take it as soon as you remember

  • If more than 12 hours: protection may reduce — use backup contraception and check with a healthcare provider

No guessing. No long breaks. Just one pill a day.

Possible Side Effects

Like all hormonal contraceptives, Mercilon 28 may cause side effects — especially during the first few months while your body adjusts.

Common ones include:

  • Mild nausea

  • Breast tenderness

  • Headache

  • Mood changes

  • Spotting between periods

Less common but serious side effects may include:

  • Blood clots

  • Severe migraine

  • High blood pressure

  • Chest pain or shortness of breath

If you notice unusual leg pain, vision problems, or severe headaches, seek medical help immediately.

Most women tolerate it well, but awareness matters.

Important Warnings & Precautions

Mercilon 28 may not be suitable if you:

  • Smoke and are over 35

  • Have a history of blood clots

  • Have uncontrolled high blood pressure

  • Have certain types of migraines

  • Have liver disease

  • Are pregnant

Always inform your doctor about:

  • Other medications (especially antibiotics or anti-seizure drugs)

  • Herbal supplements like St. John’s Wort

  • Any past hormonal issues

Hormonal pills are safe for many women, but not for everyone. A quick medical consultation makes all the difference.

Why Many Women Prefer Low-Dose Pills

Here’s the honest part. Higher estrogen pills can sometimes cause more noticeable side effects. Mercilon contains just 20 mcg of Ethinylestradiol, which is considered low-dose.

That often means:

  • Lighter periods

  • Lower estrogen-related discomfort

  • Good cycle control

Of course, every body is different. What works beautifully for one person may not feel the same for another.

Final Thoughts

Mercilon 28 is a low-dose combined oral contraceptive designed for reliable birth control with cycle regulation benefits. It’s convenient, predictable, and widely used.
