Fallback Solo Review

Fallback Solo is a hormonal emergency contraceptive that prevents pregnancy if taken within 72 hours after you have unprotected sexual intercourse or your regular birth control fails.


Indications for use

  • Emergency contraception.

Mechanism of action

Extremely high levels of hormones (levonorgestrel) cause a thickening of the cervical mucus, which creates an obstacle for the sperm to reach the ovum. This also leads to a change in the thickness of the uterine membrane, and implantation of a fertilized egg becomes impossible.

Dosage and mode of application

Fallback Solo pack contains 1 pill of levonorgestrel 1.5 mg.

Take a pill as soon as possible but no later than 72 hours after unprotected sex.

The sooner you take the drug, the more likely it will be effective. If possible, take a pill within 24 hours after unprotected sexual intercourse.

The effectiveness of emergency contraception depends on the number of hours that have elapsed since unprotected sex.

You will find out that the levonorgestrel tablet worked when you start the next period and it turns out to be normal.

Remember that emergency contraception is extremely potent, and you should not take such pills more than once during a single period. You cannot use this birth control method as an ordinary means of preventing pregnancy. Use the drug only in special situations.

Side effects

The occurrence of any serious or long-term side effects after taking Fallback Solo tablet is very unlikely. As a rule, you can continue your day in the usual way.

The most common adverse reactions include:

  • nausea and vomiting;
  • headache;
  • bleeding from the vagina;
  • diarrhea;
  • fatigue.

The most common side effects are nausea, sometimes vomiting. There may be bleeding or spotting, but, as a rule, they are insignificant. Sometimes women also complain of headaches, fatigue and drowsiness, pain in the chest. All these symptoms should disappear within a few days after taking the contraceptive pill. In case of severe bleeding, a doctor’s consultation is necessary.

If the tablet was taken before ovulation, a woman can expect profuse menstrual bleeding in the near future. But if you take the pill in the luteal phase, your period may delay or extend.


Do not take Fallback Solo pill if you have any of the following contraindications:

  • disorders of blood clotting,
  • cardiovascular diseases,
  • diseases of the liver and gallbladder,
  • vaginal bleeding of unclear origin,
  • breast cancer (including in an anamnesis),
  • pregnancy.

It is not recommended to use emergency contraception if you suffer from arterial hypertension, diabetes.


Fallback Solo may interact with certain drugs. Its contraceptive effect may be reduced by rifampicin, ampicillin, tetracycline, barbiturates, carbamazepine, griseofulvin, preparations of St. John’s wort. In its turn, levonorgestrel may increase the toxicity of cycloserine.

Fallback Solo and pregnancy

If you are already pregnant, the pill simply does not work.

If you think you are pregnant, contact your doctor or family planning clinic as soon as possible.

If you have already taken the pill once since your last period and now find yourself pregnant, do not take this drug again.


Fallback Solo is not taken more than once a month, otherwise, the hormonal regulation of the woman’s body will be disrupted and this will lead to menstrual irregularities and even infertility.

The levonorgestrel birth control pill can be used in exceptional circumstances, it is not a regular contraceptive method.

The effectiveness of emergency contraception decreases with time.

The medication will not protect you from HIV infection and other sexually transmitted diseases (STDs).

Nausea and vomiting:

After taking a pill, some women (about 1 in 100) may have nausea or vomiting. If you vomit within 3 hours after taking the pill, you need to take another levonorgestrel 1.5 mg pill. If vomiting occurred more than 3 hours after taking the tablet, you do not need to take another pill of Fallback Solo.

When you should consult a doctor:

  • If menstruation is delayed by more than 5 days or if it is unusually abundant or meager;
  • If you are still worried that you are pregnant;
  • If you have sudden or unusual pain in the lower abdomen and your menstruation is late;
  • If you have doubts about your health or birth control methods that are most suitable for you.


Unfortunately, this method of preventing pregnancy does not give a 100% guarantee. The sooner you take the pill, the more likely it will work and prevent pregnancy. Fallback Solo is most effective when taken within the first 12 hours. If you take the pill immediately after sex or within 24 hours after it, the efficiency is almost 100%. The effectiveness decreases to 50% when a pill is taken within 36-72 hours.
