Conditions Treated by Mercilon®
Mercilon® is a brand of oral birth control medication. It is known as a combined birth control pill as it contains both Estrogena dn Progestogen compounds. Mini-pills only contain Estrogen. Unlike some other combined birth controls is not used for other purposes like clearing up acne, it does still help with other menstrual conditions like helping menstrual regulation, PMS and reduces menstrual cramping. The Progestin hormone in Mercilon® works in two ways to help prevent pregnancy. When the pill is taken orally the Progestin gets secreted into the bloodstream. This is where Mercilon® controls how you avoid becoming pregnant. The hormone controls when the egg is released from the ovaries and it also thickens the cervical mucus which blocks the sperm from reaching the egg. If the egg cannot be reached y the sperm then no pregnancy can happen!
Mercilon® Dosage Information
  • Typical dosage recommendations
    Mercilon® birth control medication should be taken orally once once a day. It is advised to take Mercilon® at the same time every day. This will help you avoid missing doses by mistake. It will also better ensure that you remain covered with steady hormone levels throughout the month. You should take the very first dose of Mercilon® on the first day of your menstrual cycle, the day when your period begins. There are 28 pills in each strip, the last few of them are placebo pills. When you reach the end of the strip immediately start taking the next strip. There is no need to have a break in between packets like you have to do when taking some other brands of birth control. We like birth control that contains placebo pills, it just means that there is no need for calculation the break days and less chance that you might forget to start the next strip on time. All you have to do is work your way around the strip of tablets make sure that you take a pill once a day, at the same time every day.

    Accidents do happen. If you skip a dose consult with your doctor or the Mercilon® packet insert which contains missed doses instructions. Missing a dose or being late for a dose can result the birth control being less effective, which leave you open to becoming pregnant.

    Always keep a ready stock of Mercilon® in your medicine cabinet in case of missed doses or emergency.
  • Missing a dose
    Mercilon® is 99% effective in preventing pregnancy but it's only this effective if it is used every day as prescribed. After 12 hours delay in taking a pill Mercilon® becomes ineffective and you are no longer protected against becoming pregnant. If you are a few hours later in taking the pill, take it as soon as possible and then take the next dose at the scheduled time. If you totally miss the dose and do not remember until you are about the take the next scheduled dose then take both doses at the same time. You are not protected from pregnancy when this happens so make sure you use a barrier contraceptive for 2 days afterwards to ensure that you are fully protected against pregnancy.

    If you miss 3 doses of Mercilon® in a row then ask your doctor what to do. It's probably better to discard the current strip of pills and start a new pack instead. Always use a supplementary birth control method like condoms, spermicides etc when you miss a dose to avoid becoming pregnant.
  • Overdosing
    Overdosing can happen by accident, especially when you have missed some doses and take multiple doses at the same time. Always consult with your doctor on what to do when you miss a dose of Mercilon®. This is especially important if it is the second time that you have missed a dose in the same strip of pills. If you have taken multiple Mercilon® doses and experience nausea, vomiting, extreme stomach pain and vaginal bleeding. then you could be suffering from an overdose. Contact your doctor immediately.
Mercilon® Side Effects
Like most medications and other brands of birth control, Mercilon® has side effects. Most Mercilon® side effects are nothing to worry about but some of them can be very serious. If the side effects last more than one day then consult with your doctor and consider changing birth control. The most common side effects of Mercilon® include nausea, headaches, depression, low libido, acne, breast pain, weight gain and changes to the menstruation like irregular bleeding or no bleeding. Even though these side effects sound minor you should let your doctor know about them.

It's possible that you can start feeling very tired or start experiencing vaginal infections, hair loss, painful periods, very heavy periods or start vomiting when taking Mercilon® birth control. If the side effects are affecting your quality of life then talk to your doctor about switching birth control. You might experience less side effects using a different method of birth control or a different strength birth control pill. Likewise, if you wear contact lenses and find that they are not as comfortable as they used to be or if you start developing skin rashes or get an ovarian cyst.

In rare cases Mercilon® can cause very serious side effects like blood problems, nipple discharge, gallstones, hearing loss, liver problems and high blood pressure. See the packet insert for full details of side effects. If you experience a sever side effect then stop taking Mercilon® immediately.

It’s rare but it is possible to have an allergic reaction to Mercilon®. If you start experiencing hives, difficulty in breathing, facial swelling, swelling of the lips, tongue or nose then go straight to the doctor and stop taking Mercilon® immediately. Other serious side effects may include sudden numbness or weakness, loss of sensation in certain parts of the body, severe headaches, confusion, problems with speech and hearing, blurred vision or balance.
