If you forgot to take progesterone last night, take the missed capsule as soon as you remember, unless it’s nearly time for your next dose. If it is, skip the missed one and take the next at your usual time. Don’t take two to make up for it. That is the NHS advice for Utrogestan, the micronised progesterone widely prescribed with oestrogen in the UK, and the leaflet for generic progesterone 100mg capsules gives the same instruction.
For one missed night, that is the whole of the advice. Missing a week or more is different, and worth a call to your GP surgery, pharmacist or menopause clinic. This page is about the separate progesterone capsule, often called the progesterone pill. If your progestogen is part of a combined tablet or patch, follow that product’s leaflet.
Key takeaways
- Forgot last night: take it when you remember, unless your next dose is nearly due. Never double up.
- Utrogestan is taken at bedtime, at least two hours after food, and can make you sleepy or dizzy. So plan carefully around a daytime dose, especially if you drive.
- Progesterone protects your womb lining from the thickening oestrogen can cause, which is why it matters that you take all the doses you’re prescribed.
- Forgot for a week or more: don’t take extra capsules to catch up. Ask your GP surgery, pharmacist or menopause clinic how to carry on.
- On sequential HRT, missed doses can cause bleeding. Note which nights you missed, log and track any bleeding, as you’re likely to be asked.
What should I do if I forgot to take my progesterone last night?
The NHS advice for Utrogestan is short: ‘take it as soon as you remember, unless it’s nearly time for your next dose. In this case, skip the missed dose and take the next dose at your usual time.’ It adds: ‘Do not take 2 doses to make up for a missed dose.’
What the advice doesn’t define is ‘nearly time’. Progesterone is a once-a-day dose at bedtime, so if you realise the next morning, tonight’s dose is still more than 12 hours away. Whether to take it now or let it go is a judgement call, and a pharmacist can answer it in a couple of minutes without an appointment.
A daytime dose has two catches. The NHS says to take Utrogestan at least two hours after food, and the Utrogestan patient leaflet says not to take it with food, so it can’t be taken with breakfast. The leaflet also warns that it can make you feel sleepy or dizzy, and says not to drive or use machinery if it does. Taking it at bedtime reduces those effects. In the middle of the day, you may experience some side effects.
The rule for one missed night is the same whatever your regimen: 200mg on days 15 to 26 of your cycle (sequential HRT), 100mg on days 1 to 25, or 100mg every night if your doctor has advised that.
Why missing progesterone is different from missing oestrogen
The oestrogen in your HRT is what eases most menopause symptoms. Progesterone is there for a different reason. If you still have a womb, oestrogen-based HRT can thicken the womb lining, which the NHS says slightly increases the risk of womb cancer. Taking progesterone with it reduces that risk.
That protection depends on taking the progesterone as prescribed. On continuous HRT, a run of missed nights means oestrogen without that protection. On sequential HRT, it means fewer progesterone days in that cycle than you were prescribed. If you forgot to take progesterone for one night, the NHS rule above covers it. A run of missed nights is something to tell your GP about.
On sequential HRT, missed doses can also cause bleeding. An NHS Scotland referral pathway for bleeding on HRT tells clinicians to check before referring anyone, because ‘missed doses or incorrect application on sequential preparations can result in bleeding’. If you bleed after missing progesterone, log and track which nights you missed. You’re likely to be asked.
Forgot to take progesterone for a week or longer
If you’ve missed several days, a week or more, don’t take extra capsules to catch up. Ring your GP surgery, pharmacist or menopause clinic and ask how to carry on. The right way to pick up again depends on your regimen and where you are in your cycle.
Some bleeding needs checking whatever the cause. The Utrogestan leaflet says irregular bleeding or spotting is common in the first three to six months (we have built functionality to capture unexpected bleeding), and to see your doctor as soon as possible if irregular bleeding carries on beyond six months, starts after more than six months of use, or continues after you stop. British Menopause Society guidance for clinicians also treats heavy bleeding (flooding or clots), a withdrawal bleed lasting more than seven days, and bleeding, even light, on most days for four weeks or more as reasons to investigate.
If the gap happened because your supply ran out, ask a community pharmacist about an emergency supply, or use NHS 111 out of hours, rather than waiting days for a GP appointment.
TALIA reminds you to take your progesterone on the days you take it, whether that’s every night or set days of each cycle, and keeps a record of each dose you log alongside any spotting or bleeding. It can also warn you when your supply is running low. Everything stays on your phone. Download TALIA for iPhone or Android.
Can’t remember if you took your progesterone?
With brain fog, this one comes up a lot. The official guidance covers a dose you know you missed, not one you can’t remember. TALIA shows you in your History when a dose was missed.
On the extra-dose side, the NHS says taking an extra dose of Utrogestan ‘is unlikely to harm you’, though you may feel drowsy, dizzy, sleepy or tired. The leaflets are more cautious: if you’ve taken more than you should, they say to contact your doctor or a hospital.
Our suggestion, if you really can’t tell, is to wait for your next scheduled dose, so you can’t end up taking two. A pharmacist can help you decide.
The longer-term fix is a record, not a better memory. Tick each dose off in TALIA so you don’t have to rely on your memory.
If you keep forgetting your progesterone
Progesterone is easy to lose track of: a separate product on a different rhythm from your oestrogen, taken at bedtime when you’re tired and, on sequential HRT, only on 12 days of each cycle,
A few things help:
- Tie it to something you do every night anyway, such as brushing your teeth, while keeping the two-hour gap after food.
- Use a reminder that follows your actual schedule, so it isn’t a daily alarm you learn to ignore on the nights off.
- Track your supply so the next prescription is ordered before you run out.
If it keeps happening, tell your GP. There is more than one way to take the progestogen part of HRT. The NHS page on types of HRT says the Mirena coil ‘can be a good option if you do not want to take or use a medicine every day’, and that patches may be better than tablets if you ‘are likely to forget to take it’. Combined HRT patches contain both hormones.
If it’s your oestrogen patch, gel or spray you’ve missed, see what to do if you forget your HRT. For keeping several products in one record, there’s more on tracking HRT patches, gels and sprays.
Frequently asked questions
What should I do if I forgot to take my progesterone last night?
Take it as soon as you remember, unless it’s nearly time for your next dose, in which case skip it and take the next one at your usual time. Don’t take two to make up for it. That is the NHS advice for Utrogestan, and the leaflet for generic progesterone 100mg capsules gives the same instruction.
Can I take my progesterone in the morning if I forgot it last night?
The NHS rule allows it, as long as your next dose isn’t nearly due. Take it at least two hours after food, and don’t drive if it makes you sleepy or dizzy, which it can. If you’re unsure whether to take it or skip it, ask a pharmacist.
What happens if I forgot to take progesterone for a week?
On continuous HRT, that’s a week of oestrogen without the progesterone that protects your womb lining. On sequential HRT, it means fewer progesterone days that cycle than you were prescribed. Don’t take extra capsules to catch up. Ask your GP surgery, pharmacist or menopause clinic how to carry on, and log any bleeding.
Can a missed progesterone dose cause bleeding?
Yes. An NHS Scotland referral pathway says missed doses on sequential HRT can cause bleeding, and tells clinicians to check for this before referring. Whatever the cause, see your GP if bleeding is heavy (flooding or clots), a withdrawal bleed lasts more than seven days, you bleed on most days for four weeks or more, or irregular bleeding carries on beyond six months or starts after six months on HRT.
I can’t remember if I took my progesterone. Should I take another?
The official guidance doesn’t cover not knowing one way or the other. Waiting for your next scheduled dose means you can’t end up taking two. The NHS says an extra dose of Utrogestan is unlikely to harm you, but the leaflets say to contact your doctor if you’ve taken more than you should, so ask a pharmacist if you’re unsure.
