The morning after pill

Emergency contraception in the Adler pharmacy

In Switzerland there is the possibility of emergency contraception without a prescription after unprotected sexual intercourse. As soon as possible after a contraceptive breakdown, but no later than 120 hours afterwards, the use of a hormonal emergency contraceptive can significantly reduce the likelihood of an unwanted pregnancy following a consultation with the pharmacist.
The emergency contraceptive pill is intended for emergency situations such as condom failure, pill-taking errors or other situations of unsafe contraception. It does not protect against sexually transmitted diseases such as HIV infection or bacterial diseases (syphilis or gonorrhoea)

Background knowledge about the morning after pill

The time of ovulation determines the fertile days in the cycle. Ovulation usually takes place between the 12th and 16th day before the next menstruation, but the cycle can be shortened or prolonged by various factors such as travel, diet, illness or stress. That is why it is difficult to predict "safe days" without a medical aid.
It is possible to take the morning after pill at any time during the cycle.
For the rest of the cycle, and until you have started using another effective contraceptive, an additional method of contraception, e.g. condoms, must be used.

Bleeding delayed

The next menstrual period can be postponed and start a few days earlier or later. If menstruation is delayed by more than 5 days or if there is abnormal bleeding (less severe, unusually long or painful), we recommend that you consult a doctor as soon as possible.

Effect on fertility

Fertility is not affected by taking the emergency contraceptive pill.

Effecting mechanism

According to current knowledge, the main effect of levonorgestrel is to inhibit or delay ovulation. Further effects such as inhibition of implantation in the uterine lining and a change in cervical mucus are discussed.
  • The earlier the tablet is taken, the more effective it is.
  • The active ingredient does not lead to an abortion of an existing pregnancy.

Unwanted side effects

The following side effects may occur especially in the first days after taking the morning after pill: Nausea, headache, lower abdominal pain, fatigue, dizziness or vomiting. In case of vomiting within 3 hours after taking the tablet or severe diarrhoea within 12 hours, an additional tablet must be taken as soon as possible. Breast tenderness and spotting or intermittent bleeding may persist until the next menstrual period.
The drug may interfere with the ability to react. Caution when driving.
If the treatment was ineffective, i.e. if you become pregnant despite taking the morning after pill, no harmful effect on the baby can be expected.

Other emergency contraceptive options are:

  • the hormone pill with ulipristal acetate:
From 18 years of age, prescription only, up to 120 hours after unprotected sexual intercourse at the latest.
  • the insertion of a copper spiral by the gynaecologist
