How to get SMZ-TMP DS online in Canada with Maple.

First, choose your symptoms

Select your symptoms within the Maple app so the doctor can evaluate your symptoms and condition. Enter as much information as possible so that the doctor can make a thorough assessment.

If you don’t have employer / insurer coverage, fees may apply since many of our services aren’t covered by provincial health plans. This is often because of our use of secure messaging and a national network of doctors and nurse practitioners.

Payment may be required, and will include the prescriptions for SMZ-TMP DS if the doctor deems it necessary.

Next, you'll hear from the doctor

Once you’ve entered your symptoms, a doctor or nurse practitioner will review your case. If they’re able to help, your visit will start; if they can’t help, you’ll be notified before your consultation begins and you won’t be charged. You’re only charged if you speak with a Maple doctor.

Most often, you’ll speak to your doctor or nurse practitioner over text, though they may request audio or video chat if it’ll help with your diagnosis.

Get your medication

You'll get a prescription right on Maple, so you can send it to any pharmacy for pickup, or you can have it shipped with free delivery.

In some cases, a prescription won’t be recommended by the doctor. They will let you know if this is the case. Doctors may also not be able to prescribe some medications in certain provinces or regions.

Note: Maple is not a pharmaceutical manufacturer, nor are we an online pharmacy. This means you'll need to buy the medication from the pharmacy itself once you have your prescription.

Frequently Asked Questions

What is SMZ-TMP DS and how does it work?

Sulfamethoxazole trimethoprim (SMZ-TMP DS) is a medication which is a combination of two different antibiotics.

A SMZ-TMP DS prescription works by targeting and eliminating the bacteria that causes many different kinds of infections from within the body.

What are the uses for SMZ-TMP DS?

Sulfamethoxazole trimethoprim is most frequently used to treat bacterial infections.

Some examples of these kinds of infections include:

  • Bronchitis
  • Traveler’s diarrhea
  • Otitis media (middle ear infections)
  • Urinary tract infections

In cancer patients or patients who’ve undergone an organ transplant, sulfamethoxazole trimethoprim can be used to treat or prevent certain kinds of pneumonia (i.e. Pneumocystis jiroveci pneumonia, Pneumocystis carinii pneumonia).

This is also given to treat or prevent certain kinds of pneumonia in patients who have compromised immune systems, such as those caused by diseases like HIV or AIDS.

How do you use SMZ-TMP DS?

If you’ve been given a SMZ-TMP DS prescription online, it’ll only be available as a tablet or oral suspension liquid, to be taken by mouth. 

Dosage and frequency of use will depend on your needs, as well as the recommendations of the doctor.

Sulfamethoxazole trimethoprim should be taken with at least 8 ounces of water. If you begin to experience nausea or an upset stomach while taking this medication, it can be taken with milk or food to reduce these symptoms.

You should try to drink plenty of fluids during the course of this medication, to prevent kidney stones from forming.

Always take this medication until the full prescribed amount is finished, even if the symptoms of your illness disappear after a few days. Stopping the prescription prematurely could allow the bacteria to return, causing a relapse.

What are the side effects and risks of SMZ-TMP DS?

Common side effects from taking sulfamethoxazole trimethoprim include:

  • Nausea
  • Vomiting
  • Diarrhea
  • Loss of appetite

These side effects are normal and aren’t a cause for concern.

However, if you begin to experience any of the following, consult a doctor immediately:

  • Muscle weakness

  • Trouble breathing
  • Vision changes

These could be signs that you’re having an allergic reaction to sulfamethoxazole trimethoprim, and you should seek medical attention.

Tell your doctor immediately if you begin to experience:

  • Persistent diarrhea
  • Severe abdominal or stomach pain/cramping
  • Blood or mucus in your stool
