Prescription refill online in Puerto Rico

A prescription refill online in Puerto Rico is a follow-up video visit to renew a non-controlled medicine you already take, even if another doctor prescribed it. Dr. Diana Nieves Castro, a Puerto Rico-licensed physician, checks how it's going and, if appropriate, prescribes it and we send your prescription to your pharmacy.

Is this an emergency?

This is not an emergency service. Call 911 or go to the nearest emergency room if you have:

  • Chest pain or pressure, or trouble breathing
  • Confusion or fainting
  • Signs of very low or very high blood sugar
  • An allergic reaction with swelling of the tongue or lips

What an online refill visit is

It's a way to renew your prescription without waiting for an in-person appointment: you're running low on your blood pressure pill, your inhaler or your thyroid medicine, and you need a new prescription for the pharmacy.

Anyone who already takes the medicine can book, even if we've never seen you and another doctor prescribed it. The doctor evaluates you in real time, because renewing a medicine is a medical decision, not paperwork.

How we renew your prescription by video

The doctor asks what you take the medicine for, how it's working, whether you've had side effects and what else you take. If you check your blood pressure or blood sugar at home, have your readings ready.

If appropriate, the doctor prescribes and we send your prescription to your pharmacy. Call the pharmacy first to check they have it in stock; your pharmacy benefit may cover it even though we don't bill insurance.

Online prescription refill price in Puerto Rico

A refill is a follow-up visit, the same price for every age, with no membership. You pay the pharmacy for the medicine.

If the doctor finds you need a full doctor visit, for example because of a new symptom, a side effect or a medicine that isn't working, she explains why and, only with your consent, you pay the difference. More on the follow-up visit page. Need a medicine you've never taken rather than a refill? See getting a new prescription online.

Which medicines you can refill: common examples

Non-controlled maintenance medicines you already take. Don’t change the dose or stop a medicine on your own while you wait for your visit. These are some of the most common refills:

  • High blood pressure, for example losartan.
  • High cholesterol, for example atorvastatin or another statin.
  • Type 2 diabetes, for example metformin or insulin such as insulin glargine (Lantus). If you use insulin, renew your prescription before hurricane season and read how to store it when the power goes out in medications and hurricanes.
  • Thyroid conditions, for example levothyroxine for hypothyroidism.
  • Asthma, for example an albuterol inhaler, and allergies.
  • Acid reflux or heartburn, and birth control you already use.
  • An antidepressant you already take, for example for anxiety or depression (see anxiety or depression medicines), if the doctor considers it appropriate to continue it.
  • If you already use Ozempic or Mounjaro for diabetes, the doctor evaluates the renewal if appropriate. If you want to start a weight-loss treatment, see medically supervised weight loss.
  • Other maintenance treatments the doctor considers appropriate to continue.

Controlled medicines

Some medicines, such as opioid pain medicines, benzodiazepines for anxiety or sleep, and ADHD stimulants, are controlled substances, and federal and Puerto Rico law put special rules on their prescriptions. A refill in a follow-up visit is for non-controlled medicines. A controlled medicine needs a doctor visit, where the doctor decides which treatment is appropriate and safe for you; we never promise a specific medicine.

When the doctor asks for lab work

Some medicines need up-to-date tests to be renewed safely, such as an A1C for diabetes or thyroid function tests. If you need them, the doctor gives you a lab order for a lab near you, then reviews the results with you at a follow-up visit.

Ran out or left your medicine at home?

If you're visiting Puerto Rico and left a medicine at home, we can help as long as you're physically on the island. A photo of the label or the box helps a lot. See what to do about a lost or forgotten prescription, care for visitors and, if you're traveling, how to bring your medicines to the island.

When to go to the ER

If you've run out of a medicine and have chest pain, trouble breathing, confusion, signs of very low or very high blood sugar, or a severe allergic reaction, don't wait for a refill: call 911.

Book your refill

Request a visit online 24/7: book a visit and choose Follow-up visit. Have the bottle or a photo of the label ready, plus your pharmacy's name and town. For a patient under 21, a parent with patria potestad (parental authority) or a legal guardian must stay on camera for the whole visit.

How we care for you

  • We evaluate, diagnose and treat; if needed, we give you a lab order for a lab near you.

  • We see adults and children of all ages. Patients under 21: a parent with patria potestad (parental authority) or a legal guardian is on camera for the whole visit and shows photo ID.

  • Real-time video visit. We send you a secure video link. It works on your phone, tablet or computer.

  • If appropriate, the doctor prescribes and we send your prescription to your pharmacy.

  • You must be physically in Puerto Rico during the visit (visitors, tourists and cruise passengers are welcome).

  • In an emergency, call 911.

Frequently asked questions

Can I get a refill if another doctor prescribed the medicine?

Yes. Anyone who already takes the medicine can book the follow-up visit. Have the bottle or a photo of the label handy.

Can I get a refill without a visit?

No. Every refill requires a real-time evaluation with the doctor.

My prescription expired—what do I do?

Book a follow-up video visit. Even if you already take the medicine, renewing an expired prescription requires a short visit with the doctor: she reviews your medicine and how you are doing and, if appropriate, prescribes it and we send the new prescription to your pharmacy. Don’t stop the medicine on your own in the meantime, and have the bottle or a photo of the label ready.

Which pharmacy do you send the prescription to?

If appropriate, the doctor prescribes and we send your prescription to your pharmacy in Puerto Rico. Tell the doctor the name and town of the pharmacy you prefer.

Can you refill losartan, metformin or levothyroxine by video?

Yes, if the doctor considers it appropriate; they are maintenance medicines that are often renewed. Book a follow-up visit and have the bottle or a photo of the label ready. The doctor checks how you are doing and, if appropriate, prescribes and we send your prescription to your pharmacy. Sometimes she asks for up-to-date labs, such as an A1C or thyroid tests.

Do you refill sleep or anxiety medications?

A refill in a follow-up visit is for non-controlled medicines. Some sleep and anxiety medicines are controlled; those need a doctor visit, where the doctor decides which treatment is appropriate and safe, under federal and Puerto Rico law; we never promise a specific medicine.

Before you pay

Why do I pay before choosing a time?

That is how booking works: you pay first and choose your time right after, in the same process, from the times the doctor has open. Before paying you see the price and the cancellation policy.

Can I cancel or change the time?

You can cancel your visit for a full refund, or change the time at no cost up to 2 times, if you do it 24 hours or more before it starts. Within 24 hours you can no longer cancel or change the time, and there is no refund: the doctor has that time reserved for you and your consent is signed. If you don't join in the first 10 minutes of the visit, it counts as a no-show and there is no refund. If the clinic can't see you (the doctor is not available, there is a technical problem on our side, or we can't complete a required check), we refund you in full. If the clinic moves your visit, you can cancel it for a full refund even if it is less than 24 hours away.

Do you record the visit?

No. We do not record the video or audio of visits.
