4.1. Therapeutic indications

Brevinor is indicated for oral contraception, with the benefit of a low intake of oestrogen.

4.2. Posology and method of administration

Posology

The dosage of Brevinor for the initial cycle of therapy is 1 tablet taken at the same time each day from the first day of the menstrual cycle. For subsequent cycles, no tablets are taken for 7 days, then a new course is started of 1 tablet daily for the next 21 days. This sequence of 21 days on treatment, seven days off treatment is repeated for as long as contraception is required.

Patients unable to start taking Brevinor tablets on the first day of the menstrual cycle may start treatment on any day up to and including the 5th day of the menstrual cycle.

Patients starting on day 1 of their period will be protected at once. Those patients delaying therapy up to day 5 may not be protected immediately and it is recommended that another method of contraception is used for the first 7 days of tablet-taking. Suitable methods are condoms, caps plus spermicides and intra-uterine devices. The rhythm, temperature and cervical-mucus methods should not be relied upon.

Tablet omissions

Tablets must be taken daily in order to maintain adequate hormone levels and contraceptive efficacy.

If a tablet is missed within 12 hours of the correct dosage time then the missed tablet should be taken as soon as possible, even if this means taking 2 tablets on the same day, this will ensure that contraceptive protection is maintained. If one or more tablets are missed for more than 12 hours from the correct dosage time it is recommended that the patient takes the last missed tablet as soon as possible and then continues to take the rest of the tablets in the normal manner. In addition, it is recommended that extra contraceptive protection, such as a condom, is used for the next 7 days.

Patients who have missed one or more of the last 7 tablets in a pack should be advised to start the next pack of tablets as soon as the present one has finished (i.e. without the normal seven day gap between treatments). This reduces the risk of contraceptive failure resulting from tablets being missed close to a 7 day tablet free period.

Changing from another oral contraceptive

In order to ensure that contraception is maintained it is advised that the first dose of Brevinor tablets is taken on the day immediately after the patient has finished the previous pack of tablets.

Use after childbirth, miscarriage or abortion

Providing the patient is not breast feeding the first dose of Brevinor tablets should be taken on the 21st day after childbirth. This will ensure the patient is protected immediately. If there is any delay in taking the first dose, contraception may not be established until 7 days after the first tablet has been taken. In these circumstances patients should be advised that extra contraceptive methods will be necessary.

After a miscarriage or abortion patients can take the first dose of Brevinor tablets on the next day; in this way they will be protected immediately.

Method of administration

Oral administration.

4.9. Overdose

6.3. Shelf life

5 years.

6.4. Special precautions for storage
