Tri-Previfem

How to take Tri-Previfem

You should always follow the guidance given to you by your health provider and read the instructions that come with your Tri-Previfem prescription carefully – even if you’ve used it before or you feel that you’re familiar with using birth control.

It’s important to take this birth control as instructed to ensure that you’re more than 99% protected from unwanted pregnancy. The instructions will tell you what to do if you miss a dose. It’s essential with birth control that delivers varying doses of hormones, like Tri-Previfem, to take the pills according to the instructions that come with them, to make sure you’re taking them in the right order.

Here are some general instructions for taking Tri-Previfem:

• Take Tri-Previfem by mouth, usually once a day, every day (usually at the same time)
• Find the first pill in the packet of Tri-Previfem, and follow the arrows along the pill strip
• It’s important not to skip any doses, start any packs late or take your pill at a different time of day to usual as this could leave you unprotected.
  
  

You should get your period during the 7 days where you take your inactive pills. After you’ve taken the last inactive pill then you should start a new pack the next day whether you’ve had a period or not. If your period doesn’t come during this time, it’s best to get checked out by your doctor.

Some people find it useful to set a reminder to take their pill so that they don’t forget to take it, even if they’re traveling or in a different time zone.

Vomiting, diarrhea and illness can stop all birth control from working well. If you’ve been unwell you might need to use a back-up birth control method (like condoms) to ensure that you don’t become pregnant.

How long does it take Tri-Previfem to work?

If it’s the first time you’re taking birth control, or you’re starting without switching from another type of hormonal birth control then you’ll need to use another type of contraception to prevent pregnancy.

For the first cycle of Tri-Previfem, you should use an additional form of non-hormonal birth control (like condoms or spermicide) for the first 7 days to prevent pregnancy.

This will mean that the hormones in Tri-Previfem have had enough to reach optimum levels in your body to protect you from pregnancy. If you’re not sure about this or you need help, ask your doctor for advice.

What should I do if I make a mistake when taking Tri-Previfem?

If you forget to take a pill or you’ve been ill with vomiting or diarrhea, then you may not be protected. If this is the case then you should use a back-up method of birth control like condoms or spermicide for 7 days to avoid becoming pregnant.

You should follow the directions in the leaflet that come with your prescription on what to do next. If you’re not sure if you took your pill, or you think you may have taken too many birth control pills too closely together, consult your doctor for help or advice.

As the hormones in Tri-Previfem are phased, it’s important to take them in the right order to ensure that you’re getting the right hormone levels at the right times of the month. Ask your doctor for advice if you’re not sure of what to do if you think you’ve taken the wrong pill at the wrong time or if your phased doses are out of sync.

If you do not get your period during the time where you’re taking the inactive pills in the pack then you should get in touch with your doctor for a check up, especially if you have any concerns about something that might have affected the effectiveness of Tri-Previfem.
