MIRENA vs. PARAGARD
Mirena
how it works
It releases small amounts of hormones into the uterus that inhibit fertilization.
duration
Five years.
side effects
Possible spotting and cramping in the first one to three months; periods decrease by 90 percent after a year. Small chance of acne.
user experience (mother of one):
"The spotting in the first three months was annoying, but it tapered off so quickly that it didn't really bother me. Now I don't get my period anymore."
effectiveness
99.8 percent (more effective than surgical sterilization).
cost
About $270; cost of insertion can vary.*
ParaGard
how it works
Its copper casing increases the production of ions and enzymes that inhibit fertilization. It's nonhormonal and thus safe for smokers.
duration
Ten years.
side effects
Possible heavy periods and intense cramping in the first three to four months; periods return to normal after a year.
user experience (mother of two):
"Insertion only involved a moment of mild discomfort; I didn't even know my doctor had finished, it was so quick. I did have some cramping later that day and spotting the following day. It felt like an aggressive Pap test: more pressure than pain."
effectiveness
99.2 percent (the same efficacy rate as surgical sterilization).
cost
About $200; cost of insertion can vary.*
