What is Fallback solo?

Fallback Solo is used to stop pregnancy following unprotected sexual contact or the inability to use other methods for birth control (such as condom breakage or the absence of two or more birth control pills). Fallback Solo may also be employed for other purposes that are not covered in this guide to medication.

Side effects of Fallback Solo

Contact a medical professional immediately. Get medical attention immediately if you notice symptoms that are warning signs of an allergic response, such as hives, difficulty breathing, or swelling of your lips, face, and tongue. Consult your doctor or seek medical attention in an emergency if you experience extreme pain in your stomach or in your side. This could be the sign of a tubal pregnancy (a pregnancy that is implanted in the fallopian tube rather than the uterus). A tubal pregnancy can be a medical emergency.

Common adverse consequences of Fallback Solo may include:

  • Stomach pain.
  • Tenderness or pain in the breasts.
  • Nausea, vomiting, diarrhea.
  • Headache, dizziness.
  • Being fatigued and getting tired.
  • Changes in your menstrual cycle.

This is not a comprehensive list of possible side effects, and other side effects could be present. Consult your physician for advice regarding medical adverse effects. You can report symptoms to the FDA at 1-800-FDA-1088.


Fallback Solo does not end pregnancy when the fertilized egg has already been attached to the uterus. Consult a physician or pharmacist prior to taking levonorgestrel in the event that you frequently take medication to treat seizures, tuberculosis, or HIV/AIDS. Certain other medicines could make levonorgestrel less efficient.

Before you take this drug

Fallback Solo is not intended to be used as a routine method of birth control. Consult your physician about the various types of birth control options available. If you are pregnant, do not use this drug. Fallback Solo cannot end a pregnancy that is already in progress (the fertilized egg has been inserted into your uterus). Not authorized to be used by anyone less than 17 years old.

It is not recommended to take levonorgestrel if you are allergic to it. Talk to your doctor or pharmacist before you take levonorgestrel if you are regularly taking medications to treat seizures, tuberculosis, or HIV/AIDS. Certain medications may cause levonorgestrel to be less effective as an emergency contraceptive. Levonorgestrel could reduce the production of breast milk. If you are nursing, speak with your doctor.

How to take Fallback Solo?

Follow the instructions on the label exactly or as recommended by your doctor. Fallback Solo should be used as soon as possible after a sex that was not protected (no longer than 72 hours following the sex). Contact your doctor immediately in the event that you vomit within two hours of having taken Fallback Solo. Don't take another dose without consulting your physician. If your cycle is a bit late by a week or more beyond the time you expect, then you could be pregnant. Take a pregnancy test and consult your physician if you're pregnant. Fallback Solo is not a way to end pregnancy if a fertilized egg is attached to the uterus. Within 3 weeks of the time you took Fallback Solo, a doctor must confirm that you're not pregnant and that the medication has not produced any negative effects. Place it in a cool, dry place far from heat and moisture.

What happens if I miss a dose?

Because Fallback Solo is used as a single dose, it doesn't come with a daily dosage schedule.

What happens if I overdose?

Since Fallback Solo is supplied as one tablet at the exact dose, it is not likely for an overdose to occur if the levonorgestrel dose is taken as directed. Avoid taking more than one tablet at once.

What should be avoided?

Fallback Solo won't safeguard you from sexually transmitted illnesses--including HIV and AIDS. The use of a condom is your only method to safeguard yourself from these illnesses. Do not engage in sexual activities that aren't protected.

Interaction with other drugs

Certain medications may make Fallback Solo less effective, which could lead to pregnancy. Ask a doctor or pharmacist whether Fallback Solo is safe to take if you're using one of the following medications:

  • Efavirenz.
  • Rifampin
  • Seizure medication—carbamazepine, felbamate, fosphenytoin, phenobarbital, phenytoin, primidone.

This list isn't complete. Other medications can influence levonorgestrel. This includes medications that are prescribed and available over the counter, vitamins, and herbal remedies. The interactions of all drugs are included here.
