How to take Triphasil
To get immediate protection from pregnancy, start taking Triphasil on the first day of your period. You can also start taking it on days 2-5 of your period, but you’ll need to use an additional form of contraception, such as condoms, for the first seven days.
Take one pill at the same time each day, in the correct order as shown on the strips.
Once you’ve taken the 21 active pills, you’ll take the seven red, hormone-free pills. You should experience a bleed during this period. So long as you’ve taken the 21 active pills correctly and on time, you don’t need to use any extra contraception during this time.
Once the blister is finished and you’ve taken the 7 inactive pills, start a new strip on the next day. You may still be bleeding at this point. Don’t worry about this. Just start your next strip of pills regardless.
Provided you’re taking Triphasil as instructed, you’ll always start a new strip on the same day of the week.
Triphasil missed pill: what you should do
If you’re less than 12 hours late in taking a pill, take it immediately. This may mean taking two pills at once. Take any pills that follow at the usual time. Your protection from pregnancy shouldn’t be reduced.
If you’re more than 12 hours late taking a pill, or you’ve missed more than one pill, your protection from pregnancy may be impacted.
In the event that you’ve missed a pill during the first week of your period, you’ll also need to use an extra method of contraception, like condoms, for the next 7 days. If you’ve had sex during this week, you could be pregnant.
If you miss a pill during the second week of your period, take it as soon as you remember. This may mean taking two pills at the same time. Take any pills that follow as you would usually. So long as pills have been taken correctly during the seven days before the missed pill, you don’t need to use any additional forms of contraception. But if this isn’t the case, or if you’ve missed more than one pill, you should use another method of contraception for the next seven days.
Should you miss a pill during the third week of your period, take the pill you missed most recently as soon as you can, even if you have to take two pills at the same time. Any pills that follow, just take them at the usual time. But rather than taking the seven inactive pills at the end of the strip, start a new strip of active pills immediately after finishing the previous ones (in other words, skip the red pills). It’s unlikely that you’ll get any withdrawal bleeding until you’ve reached the end of the second strip, but you may experience some spotting or breakthrough bleeding on the days you are taking the pills.
Alternatively, if you miss a pill during the third week of your cycle, stop taking pills from your current strip. Then take a break from any pills for up to seven days, including days on which you forgot to take pills, and then continue with a new strip as normal.
If you’ve missed pills and don’t get a withdrawal bleed during the first, pill-free break, you may be pregnant. Contact our clinician via your Treated account and they can guide you through the next steps.
What dose of hormones does each Triphasil pill contain?
A pack of Triphasil pills contains three different doses of hormones: 30 micrograms (mcg) ethinylestradiol and 50mcg levonorgestrel, 40mcg ethinylestradiol and 75 mcg levonorgestrel, and 30mcg ethinylestradiol and 125mcg levonorgestrel.
Each strip contains six brown active tablets, five white active tablets, ten yellow active tablets and seven inactive red tablets. The six brown tablets are the 30mcg/50mcg dose, the five white tablets are the 40mcg/75mcg dose, and the yellow ochre tablets are the 30mcg/125mcg dose. The seven inactive tablets are hormone-free, meaning that they contain no active ingredients and are essentially the same as taking nothing at all. Taking the inactive pills might help you keep track of your regimen.
Because there are different quantities of hormones in each strip, it’s especially important that you take the pills in the right order to ensure that you get maximum protection from pregnancy.
