Slynd is a progestin-only birth control pill used to lower the chance for users to become pregnant.
Drospirenone is a progestin analogue of spironolactone that offers anti-mineralocorticoid and anti-androgenic activity. These properties allow Slynd to suppress ovulation without the use of estrogen.
This progestin-only pill has been found to offer effective pregnancy prevention with lower risks for adverse events than estrogen-based contraceptives. Slynd also provides a favourable bleeding pattern with its dosing regimen. You can also miss a single pill without losing efficacy.

Serious Side Effects
Some more serious adverse effects may occur when taking drospirenone. Stop taking Slynd and contact your doctor right away if you notice any of the following symptoms:
- Severe or ongoing nausea, vomiting, or diarrhea
- High potassium levels (nausea, weakness, tingling, chest pain, irregular heartbeats, loss of movement)
- Signs of a stroke (sudden numbness or weakness, sudden severe headache, slurred speech, problems with vision or balance)
- Signs of a blood clot (sudden vision loss, stabbing chest pain, shortness of breath, coughing blood, pain or warmth in one or both legs)
- Liver problems (loss of appetite, upper stomach pain, tiredness, dark urine, clay-coloured stools, jaundice)
- Symptoms of depression (trouble sleeping, weakness, tiredness, changes in mood)
Seek immediate medical attention if you develop pain in your lower stomach or side. This could indicate a tubal pregnancy, a condition where pregnancy implants in the fallopian tube instead of the uterus. Tubal pregnancies are medical emergencies and should be treated right away.

How does Slynd work for contraception?
Slynd suppresses your ovulation by altering your hormone levels. The efficacy of this medication’s contraception depends on how well you follow the directions. Studies have found that only 4 out of 100 Slynd users become pregnant during their first year of treatment.
When can I start taking Slynd?
If you are not taking any hormonal birth control, you can take Slynd on the first day of your natural menstrual cycle. If you are switching from a different hormonal contraceptive, start your Slynd blister pack on the same day you would start the next pack of your previous contraception. Follow your doctor’s directions for use and ask them if you have any questions or concerns.
