What is Portia?

Portia is what’s called a combined birth control pill. It combines two hormones, an estrogen and a progestin, whereas mini pills only contain progestin. Both of these hormones already exist in your body, but it’s possible to be sensitive to one or to both. That’s why there are so many different types of birth control pills. They all do the same thing but have different versions and different amounts of estrogen and progestin. It can be a bit intimidating — we’ll help you figure out what birth control is right for you during your consultation.

The specific versions of estrogen and progestin in Portia are ethinyl estradiol and levonorgestrel.

Is there more than one dosage of Portia birth control?

Portia birth control has .15mg of levonorgestrel and .03mg of ethinyl estradiol. You might also see the ethinyl estradiol written as 30mcg — that’s micrograms. Other birth control pills which have the same amount of levonorgestrel and ethinyl estradiol are Seasonale, Jolessa, Quasense, Introvale, Chateal EQ, Marlissa, Altavera, Levora, Lillow, Kurvelo, Levlen, Nordette, Setlakin and Ayuna. 

Portia only comes in one dosage, which means there’s no Portia Lo if you like how you feel on Portia but want to adjust the amounts of estrogen or progestin. There are however other combined pills which have the same active ingredients in a lower dose. Lutera and Aviane both have .1mg of levonorgestrel and .02mg of ethinyl estradiol. 

Do I need a prescription for Portia?

Yes. But we make that simple too. Take our online consultation and a licensed doctor will review your info and give birth control recommendations based on your medical history and what you’re looking for in your contraception. Then, you sign up for an EveAdam treatment plan that includes regular refill deliveries. Your first order should arrive in 2-5 business days and then on the schedule you set.

How Portia works

Like other combined birth control pills, Portia works by changing the hormone levels in your body. Hormonal birth control can stop ovulation, which is when the ovary releases an egg every month. If there’s no egg, there’s no pregnancy. However, ovulation doesn’t stop for everyone who takes the pill, so there are other things Portia does as well.

Normally, the lining of your uterus will grow every month so that it’s easier for a fertilized egg to implant itself there. On hormonal birth control, the lining stays thin. This is also why you’re likely to experience a shorter and lighter period on Portia. Lastly, the hormones change the consistency of your cervical mucus. The thicker mucus acts as a shield against sperm. All of these things together make it very, very unlikely that you will become pregnant while taking Portia.

How to take Portia

Take Portia at the same time every day so it can be as effective as possible. Pick a time that’ll be easy to remember and that works for every day of the week. For example, early in the morning might not be a good idea if you’re an early bird on weekdays but sleep in on weekends. Lunch time, afternoon or evening might be a better idea — but it’s up to you. Portia comes in a pack of 28 pills. The first 21 pills are active pills, which means they contain hormones. The last week of pills doesn’t contain any hormones, and will be when you get your period.

Portia birth control side effects

It’s possible you’ll experience side effects while taking Portia. Most of the side effects associated with birth control aren’t serious, and many occur just after you start taking it and go away on their own as your body adjusts to the new hormone levels. The most common side effects are nausea, vomiting, spotting, weight gain, breast tenderness and difficulty wearing contact lenses. 

Serious side effects can occur, but they’re pretty rare — especially if you don’t smoke and are generally healthy. However, it’s important to know what they are in case they do happen.

Serious side effects include:

  • Blood clots
  • Stroke or heart attack
  • Liver tumors
  • High blood pressure

If you experience any serious side effects, stop taking Portia and go to the hospital.

Portia birth control: is there a generic equivalent?

Portia is the generic form of Nordette, both of which are combined birth control pills made by Teva. They have the same ingredients in the same amounts as Seasonale, Jolessa, Quasense, Introvale, Chateal EQ, Marlissa, Altavera, Levora, Lillow, Kurvelo, Levlen, Setlakin and Ayuna. These other medications may be made by other companies so they will have different packaging, pricing and inactive ingredients — but when it comes to effectiveness, they’re all equivalent.
