Can you take Mounjaro, Ozempic or the Wegovy pill during Ramadan?
Planning doses before the month, fitting injections and tablets around Suhoor and Iftar, low blood sugar, water, and when guidance says to break the fast.
Written for the United Arab Emirates. Reading from India? India version
Many people do, with a plan agreed with their doctor before Ramadan. Dubai doctors say stable patients can usually continue, and dose increases may be paused for the month. A weekly injection can be fitted around the fast. The Wegovy pill and Rybelsus need 8 hours without food and a 30-minute wait; Foundayo has no food rules.
Key takeaways
- Doctors in Dubai told Gulf News that stable patients on Ozempic can usually continue in Ramadan, while those still raising the dose may pause the increase.1
- The IDF-DAR Ramadan guidelines say the daily GLP‑1s they reviewed, such as liraglutide, need no further changes if the dose was settled 2 to 4 weeks before Ramadan.2
- The UK label for Wegovy tablets says to take them after at least 8 hours without food, then wait 30 minutes before eating or drinking.3
- IDF-DAR says to break the fast if blood sugar falls below 3.9 mmol/L or rises above 16.6 mmol/L, or with signs of dehydration or illness.2
- A 2025 review of 4 diabetes studies found fewer documented low-sugar episodes on GLP‑1s in Ramadan than on comparison medicines, but more nausea and vomiting.4

When should your Ramadan plan be made?
Before Ramadan begins. Doctors in Dubai told Gulf News that dosing decisions should be made with a doctor before the month starts, “not improvised midway through”.1
- GLP‑1 medicines are prescription-only in the UAE and should be used under medical supervision.5
- Whether to fast is your decision, with your doctor and, if you wish, a religious scholar. This post reports guidance; it does not tell anyone whether to fast.
- We could not find UAE labels online, so label rules here come from the UK or EU labels, and we say which.
- Every risk of these medicines is in Guide 5: Side effects and risks.
- Settled doses. The doctors said patients stable on their dose “can usually continue without adjustment”, if they keep up fluids and balanced meals.1
- Still increasing? People who recently started, or are still stepping the dose up, may pause the increase and hold a lower dose for Ramadan.1
- International guidance. IDF-DAR, the main Ramadan guideline for diabetes, says liraglutide, lixisenatide and exenatide need no further changes if the dose was settled at least 2 to 4 weeks before. It does not name the weekly pens.2 A 2026 UK pharmacy article, citing IDF-DAR, suggests finishing dose increases 4 to 6 weeks before.6
Most of this guidance was written for diabetes. A 2023 review found “a dearth of studies” on GLP‑1 users without diabetes during Ramadan.7 Islamic rules also exempt people who are ill from fasting, with missed days made up later.2
Does a weekly injection break the fast?
Egypt’s official fatwa authority has ruled that an injection under the skin does not invalidate the fast. We found no UAE ruling, so ask a scholar you trust.8
The 2006 ruling from Dar al-Ifta in Egypt was about insulin injected under the skin, the same way GLP‑1 pens are used. It says “the fast of one injected under the skin is valid”.8 A UK pharmacy article, citing IDF-DAR, also says injected GLP‑1s do not invalidate the fast, while a tablet swallowed in fasting hours would.6 IDF-DAR adds that pricking a finger to test blood sugar does not break the fast.2
Changing your injection day. The EU labels for Mounjaro, Ozempic and Wegovy allow the weekly day to change, as long as at least 3 days pass between two doses.9,10,11 The UK pharmacy article suggests injecting after Iftar may ease nausea. It says not to change the day and the dose at the same time.6 Your doctor sets the plan.
How do GLP-1 tablets fit around Suhoor and Iftar?
The Wegovy pill and Rybelsus are the hard ones. Both labels say to take the tablet on an empty stomach after at least 8 hours without food, then wait 30 minutes before eating or drinking.3,12
- Wegovy pill (oral semaglutide, for weight). Swallow it whole with a sip of water, up to half a glass (120 ml). Waiting less than 30 minutes lowers how much is absorbed.3
- Rybelsus (oral semaglutide, for diabetes). The same rules on the EU label: empty stomach, up to half a glass of water, a 30-minute wait.12
- Foundayo (orforglipron). The UK label says it can be taken once a day at any time, “without food or water restriction”.13
During Ramadan, the semaglutide tablet must fit inside the night. The UK pharmacy article suggests taking it on waking for Suhoor, with the permitted sip of water, then waiting 30 minutes before eating.6 That only works if you have not eaten for the 8 hours before. Where the timing is too tight, it says an injection may suit some people better during Ramadan, as an individual decision.6
A missed tablet. The UK Wegovy tablet label says to skip a missed dose and take the next one the following day.3 For Foundayo, the UK label says to resume as soon as possible, and never take more than one tablet a day.13 Our Wegovy pill post covers the tablet in full.
Who is at risk of low blood sugar while fasting?
Mainly people with diabetes who also take insulin or a sulfonylurea, such as gliclazide. Used alone, GLP‑1s carry a low risk of severe low sugar, IDF-DAR says.2
GLP‑1s raise insulin mainly when blood sugar is high, which is why the risk is low on their own.2 Doctors in Dubai warned that low sugar can cause shakiness, weakness and confusion, especially in people on more than one diabetes medicine.1
- Blood sugar below 3.9 mmol/L (70 mg/dL).
- Blood sugar above 16.6 mmol/L (300 mg/dL).
- Signs of low or high sugar, dehydration or illness.

What about eating and drinking between Iftar and Suhoor?
Eat enough, and drink steadily through the night. A Dubai internist warned that appetite loss can lead people to skip Suhoor, causing tiredness, dizziness, dehydration and headaches.1
- Water. A Dubai endocrinologist advised two to three litres of water spread across the night, less salty food at Suhoor, and less caffeine.1
- Iftar. A large, heavy Iftar is a main trigger for nausea and bloating. The doctors advise eating slowly and smaller portions.1 The UK pharmacy article suggests 1 or 2 dates and fewer fried and sweet foods.6
- Slimming products. The doctors warned against detox teas and herbal mixtures alongside injections, as they can upset the gut and raise the heart rate.1
Persistent vomiting, severe stomach pain or signs of dehydration need a medical review, the doctors said.1 More on meals is in Eid and Iftar eating on GLP‑1s and Guide 8.
What do studies of GLP-1s in Ramadan show?
The studies are few and mostly in diabetes. They found fewer low-sugar episodes than with older diabetes medicines, but more stomach side effects.4
- A 2025 review pooled 4 studies of 754 people with type 2 diabetes who fasted. Documented low-sugar episodes with symptoms were less likely on a GLP‑1 than on comparison medicines (risk ratio 0.38, meaning about 62% lower). Nausea and vomiting were more common.4
- Weight-loss users. A 2023 review found almost no studies of people without diabetes taking GLP‑1s during Ramadan.7
- Stomach effects (feeling sick, vomiting, diarrhoea, constipation) are very common, more than 1 in 10 people, on the EU Mounjaro, Ozempic and Wegovy labels.9,10,11
- Dehydration from vomiting or diarrhoea can harm the kidneys, the EU labels warn.10,11
- Low blood sugar is more likely with insulin or a sulfonylurea.2
- Pancreatitis is uncommon (1 in 100 to 1 in 1,000) on the EU Mounjaro, Ozempic and Wegovy labels. The sign is severe stomach pain that won’t go away.9,10,11
Questions people ask
Can I take Mounjaro during Ramadan?
Ramadan guidance does not rule it out. Dubai doctors say stable patients can usually continue, and the plan should be agreed with a doctor before Ramadan begins.1
Does a Mounjaro injection break my fast?
Egypt’s Dar al-Ifta ruled that an injection under the skin does not invalidate the fast.8 We found no UAE ruling, so you may wish to ask a scholar.
What is the best time to inject in Ramadan?
The labels allow you to move your weekly day if at least 3 days pass between doses.9,10 A UK pharmacy article suggests injecting after Iftar may ease nausea.6
When should I take the Wegovy pill in Ramadan?
The label needs 8 hours without food before it and a 30-minute wait after.3 A UK pharmacy article suggests taking it on waking for Suhoor.6
When should I break my fast?
IDF-DAR says to break it if blood sugar is below 3.9 mmol/L or above 16.6 mmol/L, or with signs of low sugar, dehydration or illness.2
How we researched this
On 12 October 2026 we read the IDF-DAR 2021 Ramadan guidelines, a February 2026 Gulf News report quoting doctors in Dubai, the Dar al-Ifta fatwa on injections, a 2026 UK pharmacy article, and the UK and EU labels for the medicines. Study figures come from the published reviews.
We found no UAE fatwa on injections while fasting and no UAE guidance on GLP‑1 tablets in Ramadan, so we say where each source comes from. We left out insulin and sulfonylurea dose changes, because they read as dosing instructions. Ramadan dates move each year; check the official announcement.
Before you move on
- Agree your Ramadan plan with your doctor before the month starts.
- Weekly injections can be moved if at least 3 days pass between doses.
- The Wegovy pill and Rybelsus need 8 hours without food and a 30-minute wait; Foundayo has no food rules.
- Know IDF-DAR’s break-the-fast numbers if you have diabetes, and drink steadily overnight.
