Weight Loss Medications During Ramadan 2025

What medications can you use while fasting?

Oral medications can break your fast; however, certain medications can be used while fasting and will not break your fast such as:

• Inhalers or nebulizers
• Paracetamol suppositories
• Oxygen to help with breathing
• Intramuscular long-acting antipsychotic injections 
• Certain patches
• Vitamins and weight loss supplements (before you start the fat or after once your fasting is over) 

Besides this, if you are suffering from chronic illness or short-term illness, you can skip fasting as you have to take medications daily to manage the condition. 

Weight loss injections and Ramadan 

If you are using weight loss drugs, particularly GLP-1 receptor agonists in Ramadan, you must administer them with extra precautions while fasting.  

Mounjaro or Wegovy while fasting during Ramadan?

You can take Mounjaro or other GLP-1s while fasting during Ramadan as according to Islamic scholars and medical experts, necessary treatments do not break your fast until they come under the category of vital medical treatments. 

Whether you should take weight loss injections during Ramadan or not depends on your health condition and medical advice. If fasting leads you to dizziness, hypoglycemia, or weakness, breaking the fast is recommended. 

Moreover, medical professionals and Islamic scholars agree that your well-being should come first, and exceptions are made for individuals with health issues. 

What are GLP-1s and how do they work?

Medications like Mounjaro, Wegovy, Ozempic, and Saxenda, which are GLP-1 receptor agonists, are highly effective in helping you manage both type 2 diabetes and weight loss. These injectable treatments for obesity work by slowing down your digestion, curbing your hunger, helping you feel satisfied for longer periods, and regulating your blood sugar levels.

Impact of weight loss medication while fasting

Fasting with weight loss injections may increase the risk of:

• Hypoglycemia (low blood sugar level), especially if combined with other diabetic medications. Its symptoms may include sudden sweating, shaking, trembling, feeling hungry, and dizziness. 
• Nausea, slow digestion, bloating, or other digestive side effects, especially if eating large meals after iftar.
• Dehydration, since Ramadan involves long fasting hours and taking GLP-1 medications may reduce thirst and lead to dehydration.
• You must always consult your doctor before Ramadan to determine meal planning, hydration strategies, and medication dose adjustments to minimize the risk of adverse effects. 

Weight-loss pills and fasting

If you’re taking prescription weight loss pills like Orlistat, Rybelsus, or Mysimba, you need to pause/adjust while you fast during Ramadan. Align their administration with suhoor (pre-dawn meal) and iftar (meal at sunset). If you have them during the daytime or during fasting hours, it will break your fast.

Most importantly, you need to speak to your specific doctor about those medications to know their safety and effectiveness whilst fasting. Always follow medical advice in order to keep on track with weight loss goals and health in Ramadan.

What if I want to pause weight loss medications during Ramadan?

If you want to pause appetite control medications while fasting, it is essential to speak with your healthcare provider first. Some appetite suppressant medications or weight loss drugs such as Wegovy, Ozempic, etc. impact your blood sugar level, digestion, and appetite, ultimately affecting fasting. If you stop taking them suddenly, it will lead you to increased hunger, weight regain, or changes in blood sugar level. 

Consulting with your doctor will give you the best advice about dose adjustments, temporarily stopping safely, or switching to a different schedule, ensuring healthy weight loss during Ramadan.

What if I want to continue taking weight loss drugs during Ramadan?

If you want to take weight loss medications while observing Ramadan, figure out how they fit within fasting hours. Prescription weight loss injections require specific timing such as before meals or at regular intervals which may be a challenge while fasting. Consult your doctor to determine dose adjustments and the best time to take weight management treatments such as during Suhoor or Iftar. 

Best practices for using Mounjaro or other GLP-1s during Ramadan

If you want to take weight loss treatment with minimal side effects during Ramadan, follow these tips: 

1. Speak with your healthcare provider

Consult your healthcare provider to determine whether taking weight loss medications during Ramadan is safe for you. If ok, they will adjust your dosage and medication schedule and address concerns regarding fasting and medication use. 

2. Adjust your injection timing

• The best time to take weight loss medication in Ramadan is during non-fasting hours, either before suhoor or after iftar. This strategy will minimize the risk of adverse effects and help you stay on track without disrupting your fast. Stay consistent, stick to your prescription, and take your medication at the same day each week at roughly the same time (once weekly or once daily). 

3. Maintain balanced meals

If you are taking weight loss medications during Ramadan, eat a healthy, balanced diet such as:

1. Iftar: Eat light foods such as soup, and dates, protein-rich foods such as chicken & whole grains, and fiber-rich foods such as fresh vegetables before consuming complex carbohydrates and healthy fats. 
   Suhoor: Consume high-protein and high-fiber meals to stay full for longer.
2. GLP-1 obesity medications mostly cause side effects related to the digestive system such as nausea, diarrhea, constipation, and vomiting. To avoid these risks and ensure your bowel habits remain healthy, avoid processed sugar and calorie-dense meals at suhoor and iftar and drink plenty of water.

4. Stay hydrated

• GLP-1 medications can increase the risk of dehydration while fasting. So, while taking obesity treatment injections during Ramadan, drink plenty of water and consume hydrated foods such as watermelon, yogurt, and cucumbers between suhoor and iftar. Coconut water is also the best option to replenish lost fluids and electrolytes. Limit caffeinated beverages as they can lead to dehydration. 

5. Avoid increasing your dose

If you are taking weight loss medications during Ramadan, stick to your prescribed dose. If you increase your dose while fasting, it will cause serious effects that are harder to deal with while fasting. If you have any queries regarding increasing or decreasing your dose, consult your doctor for personalized advice. 

6. Monitor side effects 

While taking weight loss medications during Ramadan, if you notice nausea, dizziness, weakness, headache, or any other sign of low blood sugar level or dehydration, consult your GP immediately. You may also experience some serious side effects such as:

• Dark urine
• Mood changes
• Sweaty skin
• Rapid heartbeat or breathing
• Confusion or disorientation
• Very dry mouth, skin, and mucous membranes
• Sunken eyes
• Low blood pressure
• Blurred vision

If you experience any of these effects, break your fast and seek immediate medical help to avoid further complications. 

7. Listen to your body

If you are struggling to maintain energy levels and taking medications while fasting causes severe side effects, consult your doctor. Also, Islam allows exemption from fasting for medical reasons, so prioritize your health. 

Can I exercise while fasting on weight loss medications? 

Exercise is crucial for weight loss and stopping it can affect your weight loss goals. So, you can exercise while fasting on weight loss medications; however, you must do it safely. Choose low-moderate workouts such as walking or light strength training before suhoor or after iftar. This will replenish your energy and avoid the risk of dehydration or fatigue.

You should not start a new exercise program during Ramadan or do not overexert yourself as it can lead to exhaustion or injury. 

Ramadan weight loss plan 

Some useful tips for Ramadan fasting while on weight loss injections include:

Begin with a gentle iftar

At Iftar, break your fast with water, fruits, and a small serving of dates to replenish your energy level, raise your blood sugar levels, and restore hydration after a long period without water or food. Weight loss medications suppress appetite so avoid overeating and focus on gentle iftar to avoid the risk of adverse effects. 

Pause for Maghrib prayer 

After iftar, pause for Maghrib prayer, letting your body start digestion and develop natural satiety signals. This break also prevents overeating and controls your hunger during the subsequent main meal. 

Choose healthier cooking methods

At Iftar, prepare food with healthier cooking methods such as baking, grilling, or air-frying. It will savor your taste buds at iftar and keep your weight loss goals on track. Avoid deep-frying kebabs, samosas, and crispy pakoras. Although these foods look tempting, they contain unhealthy fats and refined carbohydrates and lead to digestive discomfort and a feeling of sluggishness. 

Embrace mindful eating

It is natural to feel hungry after hours of fasting. However, you must practice mindful eating habits at iftar and in non-fasting hours. Do not skip your pre-dawn meal and consume fiber-rich and protein-rich foods. This way will aid digestion and prevent overeating.

Prioritize sleep

Weight loss medications and fasting can affect your energy level and metabolism, so get enough rest and good quality sleep to maintain your overall health. 

What do medical experts say about fasting while using weight loss medications?

Diabetes specialists and endocrinologists have evaluated the use of GLP-1 weight loss injections (Mounjaro, Wegovy, Saxenda, etc.) during Ramadan. According to the study, these medications are safe and can be used while fasting due to their greater weight reduction and low risk of causing hypoglycemia. 

Another study indicated that combining GLP-1 agonists with moderate exercise during Ramadan can effectively reduce body mass index and improve overall health. However, the individual responses vary, consult your doctor for personalized advice. 

Final thoughts on Ramadan and weight loss medication

Mounjaro, Wegovy, Saxenda, and other GLP-1 medications are effective and safe to use for weight loss while fasting in Ramadan. However, you must adjust the dosage timing with proper planning and medical consultation to avoid the risk of adverse effects. Maintain your injection timing, eat a balanced meal, monitor side effects, and stay well-hydrated for optimal results.
