Top Generic choice
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Plan B 1-Step is an OTC emergency contraceptive medication for pregnancy prevention. Morning after pills are to prevent a pregnancy if barrier protection birth control is not used or fails and the woman is not taking an oral contraceptive. It works by temporarily delaying ovulation so that sperm do not meet an egg like they would without the use of emergency contraceptive. Plan B one step birth control must be taken within 72 hours of having unprotected sex. You can buy Plan B One Step OTC here at Canpharm with no prescription required.

Let the pharmacist know of any history of liver or kidney problems before purchasing this medication
Medication is only to be used for a single episode of unprotected intercourse, and using a barrier contraception method will be necessary until your next period. Wait 5 days after using emergency contraception medication before any resumption of use with hormonal birth control methods.
Never exceed dosage regulations of 1 tablet at one time, and be aware that this medication is an emergency contraceptive and will not work for month-to-month birth control
Be aware that unprotected sex not only increases the chance of unplanned pregnancy, but also increases your risk for STIs (sexually transmitted infections)

How long is Plan B One-Step effective?
Plan B One-Step is most effective when taken within 72 hours (3 days) after unprotected sex. However, it works best within the first 24 hours, reducing the risk of pregnancy by up to 87–95%. Its effectiveness decreases the longer you wait.
How to know if Plan B One-Step worked?
There is no immediate way to tell if Plan B worked. However, signs that it was effective include:
Can I take Plan B One-Step while breastfeeding?
Yes, Plan B is safe to take while breastfeeding. Only a small amount of the hormone levonorgestrel passes into breast milk and is unlikely to harm the baby.
Can Plan B One-Step delay your period?
Yes, Plan B can cause temporary changes to your menstrual cycle. Your period may come earlier or later than expected, and flow may be lighter or heavier than usual.
Does Plan B One-Step expire?
Yes, Plan B has an expiration date (usually 3–4 years after manufacturing). Using it after expiration may reduce its effectiveness, so check the package before taking it.
How long does Plan B One-Step last in your system?
Plan B remains in the body for a few days, but its effects on ovulation and hormones may last for a full menstrual cycle.
How often can you take Plan B One-Step?
You can take Plan B multiple times, but it should not be used as regular birth control. Frequent use may cause irregular periods, hormonal imbalance, and side effects like nausea or fatigue.
Does Plan B work if you are overweight?
Plan B may be less effective in people who weigh over 165 lbs (75 kg). Ella (a different emergency contraceptive) or a copper IUD may be better options for individuals in this weight range.
Can Plan B cause cramps?
Yes, Plan B can cause cramping similar to menstrual cramps. This is a common side effect as your body reacts to the hormone changes.
Can you take Plan B and birth control pills together?
Yes, you can take Plan B while on birth control. However, if you missed pills before taking Plan B, continue your regular birth control but use backup contraception (like condoms) for 7 days.
