Shipping Update

We are now seeing improvements in our shipping times. However, things are not yet back to normal and there are still some delays occurring. We will provide updates as the situation changes.

Our normal shipping time averages 1 - 2 weeks. Due to the pandemic, shipments may sometimes take an additional 2 – 4 weeks to arrive, depending on the source country of your order. Shipments from the United Kingdom and Canada are generally quicker than from other countries.

Please note that these times are averages and individual shipping times will vary. We highly recommend that you place your order at least 2 – 4 weeks or more ahead of your normal reorder time to avoid running out of your medication.

We offer a shipping guarantee when you place an order with us. If your order does not arrive within 6 weeks from the date it was shipped, we will re-ship your order to you at no additional cost.

What Janumet is and what it is used for

Janumet contains two different medicines called sitagliptin and metformin.
• sitagliptin belongs to a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors)
• metformin belongs to a class of medicines called biguanides. They work together to control blood sugar levels in adult patients with a form of diabetes called ‘type 2 diabetes mellitus’. This medicine helps to increase the levels of insulin produced after a meal and lowers the amount of sugar made by your body. Along with diet and exercise, this medicine helps lower your blood sugar. This medicine can be used alone or with certain other medicines for diabetes (insulin, sulphonylureas, or glitazones). What is type 2 diabetes? Type 2 diabetes is a condition in which your body does not make enough insulin, and the insulin that your body produces does not work as well as it should. Your body can also make too much sugar. When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems like heart disease, kidney disease, blindness, and amputation.

How to take Janumet

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
• Take one tablet:
• twice daily by mouth
• with meals to lower your chance of an upset stomach.
• Your doctor may need to increase your dose to control your blood sugar.
• If you have reduced kidney function, your doctor may prescribe a lower dose. You should continue the diet recommended by your doctor during treatment with this medicine and take care that your carbohydrate intake is equally distributed over the day. This medicine alone is unlikely to cause abnormally low blood sugar (hypoglycaemia). When this medicine is used with a sulphonylurea medicine or with insulin, low blood sugar can occur and your doctor may reduce the dose of your sulphonylurea or insulin. If you take more Janumet than you should If you take more than the prescribed dosage of this medicine, contact your doctor immediately. Go to the hospital if you have symptoms of lactic acidosis such as feeling cold or uncomfortable, severe nausea or vomiting, stomach ache, unexplained weight loss, muscular cramps, or rapid breathing (see section “Warnings and precautions”). If you forget to take Janumet If you miss a dose, take it as soon as you remember. If you do not remember until it is time for your next dose, skip the missed dose and go back to your regular schedule. Do not take a double dose of this medicine. If you stop taking Janumet Continue to take this medicine as long as your doctor prescribes it so you can continue to help control your blood sugar. You should not stop taking this medicine without talking to your doctor first. If you stop taking Janumet, your blood sugar may rise again. If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. STOP taking Janumet and contact a doctor immediately if you notice any of the following serious side effects:
• Severe and persistent pain in the abdomen (stomach area) which might reach through to your back with or without nausea and vomiting, as these could be signs of an inflamed pancreas (pancreatitis). Janumet may cause a very rare (may affect up to 1 in 10,000 people), but very serious side effect called lactic acidosis (see section “Warnings and precautions”). If this happens, you must stop taking Janumet and contact a doctor or the nearest hospital immediately, as lactic acidosis may lead to coma. If you have a serious allergic reaction (frequency not known), including rash, hives, blisters on the skin/peeling skin and swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing, stop taking this medicine and call your doctor right away. Your doctor may prescribe a medicine to treat your allergic reaction and a different medicine for your diabetes.

Uncommon (may affect up to 1 in 100 people): stomach ache, diarrhoea, constipation, drowsiness Some patients have experienced diarrhoea, nausea, flatulence, constipation, stomach ache or vomiting when starting the combination of sitagliptin and metformin together (frequency is common).
