Femoston

  • Hormone Replacement Therapy (HRT)
  • For relief of menopausal symptoms
  • No tablet-free week

About Femoston

Femoston is a Hormone Replacement Therapy (HRT). It contains two types of female hormones, an oestrogen (oestradiol) and a progestogen (dydrogesterone). Femoston is used in postmenopausal women who have not had a period in more than six months.

Femoston is used for:

  • Relief of symptoms occurring after menopause (e.g., hot flashes).
  • Prevention of osteoporosis (fragile bones).

How to use Femoston

Always use this medicine exactly as your doctor or pharmacist has told you. Contact your doctor or pharmacist if you are not sure.

When to start taking Femoston

You can begin taking Femoston on any convenient day if:

  • You are not taking any other HRT preparations.
  • You are switching from a combined continuous HRT product (i.e., combined oestrogenprogestogen tablets or patches).

You can begin taking Femoston immediately after the 28-day cycle if:

  • You are currently using a ‘cyclic’ or ‘sequential’ HRT preparation, which involves taking an oestrogen tablet or patch for part of the month, followed by both oestrogen and progestogen tablet or patch for up to 14 days.

How to take Femoston

Take the tablet with a drink of water. Femoston tablets can be taken with or without food. It is also important to take your tablet each day at about the same time to avoid missing a dose and to keep a constant level of medicine in the body.

Femoston is taken without a break between packs. The days of the week are printed on the back of the blister strips. This is to show you on which day to take each tablet.

Dosage

Each strip of Femoston contains 28 tablets. The two tablet strengths have different colours.

  • Take one tablet a day. Follow the order printed on the calendar pack. The tablets from the part marked with arrow 1 should be taken first, then the tablets from the part marked with arrow 2 should be taken. When a strip is empty, you must start with a new strip of Femoston on the next day. There is no tabletfree week.

Alcohol/driving

This medicine does not interact with alcohol or impair your ability to drive safely.

If you take more or less Femoston than you should/stop taking Femoston

If you have taken more Femoston tablets than you should, dizziness, nausea, breast tenderness and withdrawal bleeding may occur. No treatment is necessary, but if you are worried contact your doctor for advice.

If you forget to take Femoston, take the missed tablet as soon as you remember. If it is more than 12 hours since you took the last one, take the next dose without taking the forgotten tablet. Do not take a double dose. Bleeding or spotting may occur if you miss a dose.

Do not stop taking Femoston without consulting your doctor first.

When not to use Femoston

Femoston is not suitable for every female. Do not take this medicine if:

  • You have, or have had, breast cancer, or if you are suspected of having it.
  • You have a malignant tumour which is sensitive to oestrogens, such as cancer of the womb lining (endometrium), or if you are suspected of having it.
  • You have any unexplained vaginal bleeding.
  • You have excessive thickening of the womb lining (endometrial hyperplasia) that is not being
  • treated.
  • You have, or have had, a blood clot in a vein (thrombosis), such as in the legs (deep venous thrombosis) or the lungs (pulmonary embolism).
  • You have a blood clotting disorder (e.g., protein C, protein S, or antithrombin deficiency).
  • You have, or recently have had, a disease caused by blood clots in the arteries, such as a heart attack, stroke or angina.

  • You have a rare blood problem called porphyria, which is passed down in families.
  • You are allergic to any of the other ingredients in Femoston (see section 'What Femoston contains').

If any of the above conditions appear for the first time while taking Femoston, stop taking it at once and consult your doctor immediately.

If you are going to have surgery, tell the surgeon that you are taking Femoston. You may need to stop taking Femoston about four to six weeks before the operation to reduce the risk of a blood clot.
