Contraceptive Pills

UK Meds asked our favorite doctor, Dr. Christian Jessen, to explain Contraceptives. Below is what he has to say.

Contraceptive pills, or birth control pills are a simple and effective way to prevent pregnancy. They can also help make your periods more regular and ease menstrual cramps. They can even, in some cases, help with acne. If you follow instructions properly and you use contraceptive pills in the right way they can provide reliable protection against pregnancy.

They work by stopping ovulation, if there is no egg being released then there is nothing to be fertilized by a sperm. Most birth control pills contain synthetic forms of the female hormones estrogen and progesterone. You can order contraceptive pills by UK Meds, a prescription is required but if you don't have one, the online doctor's service at UK Meds can assist you so you can order your contraceptive pills online, such as Brevinor, Cerazette, Cerelle, Cilest, Dianette, Evra Patch and many others from the convenience of your home.

What is Loestrin?

Loestrin is a combination hormone medication used to prevent pregnancy. Loestrin has two active ingredients: norethindrone, a progestin, and ethinyl estradiol, an estrogen. The combination of the two hormones prevent the release of an egg during the menstrual cycle, makes the vaginal fluid thicker to prevent the sperm from reaching an egg, and changes the lining of the uterus to prevent attachment of a fertilized egg.

Loestrin contains a small amount of iron in inactive tablets taken during the fourth week. The inactive pills do not contain hormones but are meant to keep you in the habit of taking one tablet each day and do not have enough iron to treat iron deficiency.

Loestrin also makes your period more regular, decrease blood loss and painful periods, decrease the risks of ovarian cysts, and treat acne.

The use of Loestrin does not protect you and your partner against sexually transmitted infections such as gonorrhea and HIV.
