What is

Premarin in its oral form is a medication containing conjugated estrogens that are sustained in a slow-release tablet. Premarin is used to treat atrophic vaginitis, dyspareunia, and kraurosis vulvae. 

They have a number of uses, including:

  • As a treatment of menopausal and postmenopausal vasomotor symptoms (hot flashes and night sweats)
  • To help prevent osteoporosis caused by low estrogen levels, for those at risk of developing this condition
  • As a treatment for abnormal uterine bleeding, caused by hormone imbalances
  • As a treatment for vulvar or vaginal atrophy associated with menopause

For more resources, including a full list of the risks and benefits of Premarin tablets, please review the product monograph.

How does

As women enter the natural menopausal transition and move into the menopause life cycle, their bodies begin to produce less estrogen.

Premarin tablets work by providing their bodies with estrogen to replace the hormones that their bodies are no longer producing.

In turn, this can help reduce the severity of certain menopause-related symptoms. It also reduces the chances of experiencing certain conditions (i.e., osteoporosis, vulva or vaginal atrophy, etc.), which are also associated with the menopause life cycle.

Premarin dosage strength varies, depending on what symptoms you’re treating and the severity of those symptoms. Practitioners can prescribe Premarin tablets in 0.3mg, 0.625mg, and 1.25mg, depending on what they believe will best serve your individual needs.

What is
used to treat?

There are a number of different uses that oral Premarin treatments are used for. These include:

As a treatment for menopausal and postmenopausal symptoms (specifically, vasomotor symptoms like hot flashes and night sweats)

As a preventative treatment for osteoporosis, caused by low estrogen levels. This is only for women who are already at risk of this condition occurring

To help treat abnormal uterine bleeding, when your healthcare practitioner has been unable to determine the cause of the bleeding

As a treatment for vulva or vaginal atrophy that’s associated with menopause. Specifically, this helps treat symptoms like:

  • Itching
  • Burning
  • Vaginal dryness
  • Difficulty urinating
  • Burning sensation while urinating

The Premarin dosage recommended for you will depend on the recommendations of your healthcare practitioner, as well as the severity of your ongoing symptoms.

How do you take

Premarin tablets should be taken on the dosage schedule prescribed by your healthcare practitioner.

These tablets can be taken with or without food, but they should be swallowed whole. Don’t chew, break, or dissolve these pills.

Never take more Premarin than has been prescribed by your healthcare practitioner. 

Taking too much estrogen can be dangerous and lead to more severe side effects, while not following your dosage schedule (missing doses) can impact the efficacy of your medication

What are the common side effects of

The most common side effects from taking Premarin tablets include:

  • Breast pain
  • Breakthrough bleeding
  • Spotting
  • Joint pain
  • Hair loss
  • Changes in weight

Uncommon side effects include:

  • Change in menstrual flow
  • Nausea; bloating
  • Abdominal pain
  • Dizziness
  • Deadache (including migraine)
  • Changes in libido
  • Mood disturbances
  • Rash
  • Itching
  • Inflammation of the vagina 

There are also rare or very rare side effects that occur, appearing in less than 0.1% of people who take this medication:

  • A spontaneous flow of milk from the nipple
  • Painful periods
  • Vomiting
  • Irritability
  • Hives
  • Worsening of asthma 
  • Tender red nodules on the shins and legs
  • Increase in blood pressure 
  • Dizziness

If any of these side effects begin to become severe, be sure to talk to your healthcare practitioner at Felix. They may be able to suggest an alternative dose of Premarin, or medication that may work better for you.

MHT is the most effective treatment for menopausal symptoms and has been shown to prevent bone loss.

In menopausal women who start appropriately-dosed MHT prior to age 60 OR within 10 years of their last period, the health benefits outweigh the risks.

Risks of MHT are considered very rare (~1 case per 1000 to 10,000 women on MHT per year) and may include:

  • risks of stroke or blood clots in legs or lungs with oral estrogen (much lower risk with estrogen gel or patch)
  • risks of dementia in women older than 65 years,
  • risk of breast cancer (less than ~1 case per 1000 women on MHT per year)  

These conditions are all rare, but they highlight the importance of having a full discussion with your healthcare practitioner; especially if you’re experiencing moderate to severe side effects.

Individualization is key, and your MHT treatment plan should be reassessed (at least) once a year to monitor your health, as well as ensure that you are on the correct dosage and formulation.

Your practitioner can help you find balance between treating your symptoms safely, and avoiding increased risks.

Frequently asked questions

Premarin Tablets

Felix 101

What is Felix?

Felix is Canada’s first truly integrated healthcare platform. We provide on-demand treatment for everyday health needs like weight loss, mental health, sexual health, and more. Founded in 2019, our digital-first approach to healthcare includes everything from diagnosis to prescription — all accessible from the comfort of home.

Who can use Felix?

Anyone who is 18 years or older older (16 or older for acne and birth control prescriptions), and is located in Alberta, British Columbia, Manitoba, Newfoundland and Labrador, Nova Scotia, Prince Edward Island, Saskatchewan or Ontario. We cannot ship treaments outside of these provinces at this time.

Does Felix replace my doctor?

No. Felix provides a faster, hassle-free way for you to get a prescription to certain medications but our service does not replace your primary care provider. For matters that extend beyond obtaining a prescription lifestyle medication safely and easily, we encourage you to consult your primary health practitioner in person — whether for checkups, personal health concerns, or to inform them about the medications you are currently using.

Can I be accurately assessed remotely?

Absolutely. Our online assessments have been designed to ask all the necessary questions required for diagnosis. We've worked with specialist to create an assessment process that can provide sufficient information for the healthcare practitioner to determine whether or not you are eligible for a prescription and craft an appropriate treatment plan.

It's an emergency. What do I do?

Call 911 or proceed to your nearest emergency room immediately. Felix is not intended for medical emergencies. Once the emergency has been addressed or resolved, contact your prescribing practitioner to inform them of your experience as this may impact your current treatment plan.

Online Visits

How does this visit work?

After creating an account, you will complete a medical assessment for evaluation by one of the Felix healthcare practitioners. 

During your assessment, you will have the opportunity to send your practitioner questions via secure messaging.  

In most cases, practitioners will complete your assessment with secure messaging alone but sometimes they may determine you require an audio or video visit and/or further diagnostic testing to help determine the best treatment plan for you. 

If your practitioner has determined a prescription treatment is appropriate, they will approve your visit and write you a prescription. Our pharmacy will then ship your prescription to your home.

You’ll be able to message your healthcare practitioner if you have questions or want to make changes to your treatment at any time.

Do I need to complete my online visit at a scheduled time?

No. We use an asynchronous telemedicine model so you can complete your online visit in your own time and we save your progress so you can come back later to finish it.

If you are completing a visit in the mental health or weight loss categories, your healthcare practitioner may require a phone or video call to discuss your medical profile further during the assessment process.

Does the online visit require a phone or video appointment?

Most assessments do not require a phone or video conversation. Once a prescriber has reviewed the info in your assessment they will respond to you via secure instant messages that you can access within your Felix account.  

If you are completing a visit in the mental health or weight loss categories, your healthcare practitioner may require a phone or video call to discuss your medical profile further during the assessment process.

How quickly will a healthcare practitioner review my online visit?

You can expect to receive a response from a healthcare practitioner within 24 hours of submission. If you’ve been waiting longer than this, please email and we’ll look into it.

Can I just get the treatment and skip the online visit?

No. A visit with a licensed healthcare practitioner is required for all treatments currently provided through Felix’s service.

Please email our Customer Support team at and they will be able to assist you with the transfer.

Privacy and Security

Is my information private and secure?

Yes, your security is paramount to Felix’s mission. Personal health information provided during your medical assessment is strictly and legally confidential between you and the Felix healthcare practitioner.

Beyond that, all your account information (including the medical assessment, credit card, and shipping information, etc.) is also stored safely and securely. Felix is compliant with all federal and provincial health privacy legislation. It is our duty to protect your data with comprehensive security infrastructure and stringent data policies to ensure it stays private and secure.

Read more on our Privacy Policy.

Is this legal?

Yes! In Canada, only a licensed healthcare practitioner can write a prescription, and only a registered pharmacist can fill that prescription. We are supported by leaders in the Canadian pharmacology and specialized medical fields. Felix adheres strictly to all the regulations set forth by all applicable Colleges of Pharmacists and Colleges of Physicians and Surgeons in which we operate.

Is this safe?

Absolutely. All prescriptions obtained via Felix are provided by licensed Canadian healthcare practitioners—the same as you would get at a hospital, doctor’s office, or clinic. These practitioners do not provide prescriptions unless they deem it medically safe and appropriate to write them based on your medical profile and assessment answers. Our assessments have been crafted by the experts on our medical team. Finally, all Felix Pharmacies are provincially accredited just like any retail pharmacy.

How is my privacy protected?

Your privacy is our top priority. All your data is 256 bit SSL/TLS encrypted, and we take significant steps to keep your data secure. You can read our Privacy Policy for more information. 


How long will it take to get my treatment?

Not long. After completing your assessment, a practitioner will generally respond within 24 hours, and often much sooner.

Treatment plans will be processed within 2-3 business days of your approval date if there is nothing blocking fulfillment.

All packages are shipped via Express Post, which usually takes 2-3 business days. You will receive an email with your tracking number once your treatment has been shipped.

Is your packaging discreet?

Absolutely. All Felix shipments arrive in a nondescript blister package so you can have your treatment shipped wherever makes sense for you as long as there is someone there to sign for it.

Do I have to be home to receive my package?

A signature upon delivery may be required.

How much does it cost to ship my treatment?

There is currently no cost to have your treatment shipped to you from our Felix Pharmacy network.

What courier do you use for shipping?

Our pharmacy partners use Canada Post and/or Purolator for shipping.

Pricing and Payment

How much is the online visit?

Felix charges a fee for the online visit, but only if and when you are approved by the healthcare practitioner. In most cases the fee is $40 but varies by treatment category. The visit fee includes a prescription valid for up to a year (depending on the condition) and on-going support from the healthcare practitioner or pharmacist.

How much will my treatment cost?

It depends. Treatment costs vary but will be in line with what you would pay at a pharmacy in person. You will see the estimated cost of your treatment before insurance, during the online visit but will only be charged once approved. Once approved, your treatment and payment will be processed within one to two days.

Keep in mind that you won’t necessarily need to pay the full price yourself. If you have insurance, Felix’s partner pharmacies will bill your insurer directly. You may also be eligible for financial support in your province.

What payment methods do you accept?

We accept all major credit cards for any aspect of your treatment not covered by insurance or other financial support

When am I charged?

You will be charged for the online visit as soon as it is approved by the healthcare practitioner. From there, and after your prescription is activated by the pharmacy, you will be charged the medication cost for each shipment based on your chosen refill schedule. If you have provided insurance or benefits coverage details, it will be applied according to your plan.


Am I covered by my insurance?

Treatment coverage varies greatly between different insurance plans.

The good news is that if you are covered, Felix can bill your insurer directly, and then process your treatment plan at no additional cost to you. We recommend that you upload your private and/or provincial benefit card during the online visit so that our pharmacy partner can apply any coverage you are eligible for before processing your treatment plan.

Insurance coverage for treatment plans through Felix doesn't include the cost of your visit.

Is the online visit covered by my insurance or provincial health plans?

A Felix online visit is considered asynchronous since it is conveniently completed through a secure chat bases system. Currently, asynchronous visits are not covered by insurance or provincial health plans so you will be charged a visit fee, depending on the category of treatment you are requesting.

Is the medication covered by my insurance or provincial health plans?

Medication coverage varies greatly between different plans, provinces, and has specific criteria that determine eligibility. For private insurance, we recommend contacting your benefits administrator with your details and the Drug Identification Number (DIN) and the drug name to determine your coverage.
