There are a few different types of the Pill. The combined pill contains estrogen and progestin, which stop the ovaries from releasing eggs. The pill also thickens the cervical mucus, preventing the sperm from reaching the egg. The 'mini' pill contains only one hormone, a progestin, which offers an alternative to those affected by the hormone estrogen. Ask your healthcare provider whether the combined pill is a suitable method of contraception for you based on your medical history.
USAGE
Consume it as you would any other tablet - place it in your mouth and swallow. It is taken daily and ideally at the same time every day, regardless of whether you have sex. Different pills have different intake cycles. For example, some pill types requires you to take hormone-free pill during the breaks to maintain continuous intake. If you miss one or more pills, or start a pill pack too late, have a look into the Patient Information Booklet provided to you with the pill pack. If you have any doubts or concerns, please contact your healthcare provider.
