How To Use Kliofem

Complete Step-by-Step Usage Guide, Dosage Instructions & Safety Information

Key Takeaways: Using Kliofem Correctly

  • Dosage: One tablet daily (estradiol 2 mg + norethisterone acetate 1 mg), taken at the same time each day.
  • Administration: Swallow whole with water, with or without food. Use the calendar pack to track daily doses.
  • Missed dose: If within 12 hours, take it; if more than 12 hours, skip and continue next day. Do not double dose.
  • Starting & switching: Start any day; if switching from cyclical HRT, begin after withdrawal bleed ends.
  • Precautions: Stop Kliofem 4–6 weeks before major surgery to reduce clot risk. Avoid if you have certain cancers, liver disease, or history of blood clots.

Kliofem is a continuous combined hormone replacement therapy (HRT) taken daily without interruption. Using it correctly ensures maximum symptom relief and endometrial protection while minimising risks.

Important: When to Stop and Seek Help

Stop taking Kliofem and contact a doctor immediately if you develop: signs of blood clot (painful leg swelling, sudden chest pain, breathlessness), yellowing of skin/eyes (jaundice), sudden severe headache, migraine-like symptoms, swollen face/tongue/throat (angioedema), or if you become pregnant.

Step-by-Step Usage Guide: How to Take Kliofem

  1. Prepare your calendar pack: Turn the inner disc so that the day of the week aligns with the plastic tab. This reminds you when to take each tablet.
  2. Take the first tablet: Break the plastic tab and tip out the first tablet. Swallow it with a glass of water. Do not chew or crush.
  3. Daily routine: Each day, move the transparent dial clockwise by one space as indicated by the arrow. Take the tablet that appears in the opening. Maintain a consistent time (e.g., with breakfast) to build a habit.
  4. Finishing a pack: After taking all 28 tablets, start the next pack the following day without a break. Do not leave a gap between packs.
  5. If you need to switch from another HRT: If you are switching from a cyclical HRT (one with monthly bleeding), begin Kliofem after the withdrawal bleed ends. If switching from another continuous combined product, you can start immediately.

🗒️ Pro tip: Keep your pack visible, e.g., by your toothbrush, to help remember daily intake. Setting a phone alarm can also be helpful.

Dosage Instructions: How Much and How Often

Standard dose: One tablet daily, each containing 2 mg estradiol and 1 mg norethisterone acetate. This is a fixed dose; do not adjust without medical advice.

Duration: Your doctor will prescribe the lowest effective dose for the shortest time needed to control symptoms. Reassess at least annually.

What to do if you miss a dose

  • If you forget a dose within 12 hours of your usual time, take it as soon as you remember.
  • If more than 12 hours have passed, skip the missed dose. Take the next tablet at your usual time the following day.
  • Never take a double dose to make up for a forgotten one.
  • Missing a dose may increase the likelihood of breakthrough bleeding or spotting, especially during the first months of treatment.

If you accidentally take more than one tablet, contact your doctor or pharmacist. Overdose may cause breast tenderness, nausea, vomiting, or irregular bleeding.

Who Should Use Kliofem (Indications)

Kliofem is intended for postmenopausal women with at least 12 months since their last natural period and who still have their womb. It is used for:

  • Relief of moderate to severe menopausal symptoms such as hot flushes, night sweats, and vaginal dryness.
  • Prevention of osteoporosis in women at high risk of fractures where other treatments are unsuitable or not tolerated.

Experience in women over 65 years is limited, but it may be used if benefits outweigh risks.

Who Should NOT Use Kliofem (Contraindications)

Do not take Kliofem if any of the following apply. If you are unsure, speak to your doctor.

  • Known, past, or suspected breast cancer.
  • Known or suspected oestrogen‑dependent cancer (e.g., endometrial cancer).
  • Undiagnosed vaginal bleeding.
  • Untreated endometrial hyperplasia.
  • Current or past venous thromboembolism (deep vein thrombosis, pulmonary embolism).
  • Known thrombophilic disorder (e.g., protein C, protein S, antithrombin deficiency).
  • Active or recent arterial thromboembolic disease (heart attack, stroke, angina).
  • Liver disease with abnormal function tests.
  • Porphyria.
  • Hypersensitivity to estradiol, norethisterone, or any excipient (including lactose).

⚠️ Note: If you develop any of these conditions after starting Kliofem, stop immediately and consult your doctor.

Can Kliofem Be Taken With or Without Food?

Kliofem tablets can be taken with or without food. Swallow the tablet whole with a glass of water. There is no restriction on meals; however, taking it at the same time each day (e.g., with breakfast) helps establish a routine and reduces the chance of forgetting.

Avoid consuming grapefruit or grapefruit juice, as it may interfere with the metabolism of oestrogens, although the interaction is less pronounced than with some other drugs.

Special Conditions: Surgery, Liver Problems & Other Precautions

Surgery and prolonged immobility

If you are scheduled for surgery, inform your surgeon that you are taking Kliofem. You may need to stop taking it 4 to 6 weeks before the procedure to reduce the risk of blood clots. Ask your doctor when you can safely restart, usually after you are fully mobile again.

Liver disorders

Kliofem is metabolised in the liver. If you have a history of liver disease, your doctor will monitor your liver function. Do not use Kliofem if liver function tests are abnormal.

Other conditions requiring closer monitoring

Tell your doctor if you have: uterine fibroids, endometriosis, migraine, epilepsy, asthma, diabetes, high blood pressure, gallstones, or a family history of breast cancer. These conditions may require more frequent check‑ups while on Kliofem.

Pregnancy, Breastfeeding & Contraception Considerations

Pregnancy: Kliofem is for postmenopausal women only. If you become pregnant while taking it, stop immediately and contact your doctor. There is a potential risk to the fetus, and the product is contraindicated in pregnancy.

Breastfeeding: Do not use Kliofem if you are breastfeeding. The hormones can pass into breast milk and may affect the infant.

Contraception: If it is less than 12 months since your last period or you are under 50, you may still be fertile. Kliofem is not a contraceptive. Use additional barrier contraception (e.g., condoms) to prevent pregnancy until your doctor confirms you are postmenopausal.

Kliofem Usage FAQs

Skip the missed dose and take your next tablet at the usual time. Do not take a double dose. Missing doses may increase the chance of spotting or breakthrough bleeding.

Some medicines (e.g., epilepsy drugs, rifampicin, St John’s wort) can reduce Kliofem’s effectiveness. Always inform your doctor about all medicines, including herbal products, before starting.

You should be at least 12 months since your last natural period. If you have had a hysterectomy, timing is less strict; your doctor will guide you.

Kliofem is a continuous combined HRT, so you should not have regular periods. Some women experience irregular bleeding or spotting, especially in the first 3–6 months. If it persists, see your doctor.

You can stop at any time, but it’s best to discuss with your doctor first. Symptoms may return if you stop abruptly. Your doctor may advise tapering or switching to a lower dose.
