Safely Using Medications During Intermittent Fasting
Intermittent fasting has surged in popularity over recent years thanks to new research showing potential benefits like better weight control, lowered heart disease risk, improved mental clarity and blood sugar regulation. However, many wonder if combining intermittent fasting with taking regular medications is safe and effective.
Understanding How Intermittent Fasting Works
There are a few different intermittent fasting schedules, but the most common involves fasting for 14-16 daylight hours and restricting food intake to an 8-10 hour eating window. This fasting mimics hormonal changes that occur naturally when eating three meals a day plus snacks.
In a fasted state, blood sugar remains stable, insulin levels fall and fat burning increases. Following an eating window allows sufficient calories and nutrients to avoid deficits while still gaining advantages from fasting periods.
Using Medications Safely During Fasting Periods
Most oral prescription tablets and capsules are considered safe for use while fasting intermittently. Because there is no food intake during the fast, medication absorption into the bloodstream may even improve without a recently eaten meal.
However, some medication types require adjustments or added precautions:
- Blood sugar medications — Work with your doctor to avoid unsafe drops in blood glucose.
- Blood pressure medications — Monitor for low BP which may rise again after breaking fast.
- Antibiotics and antacids — Take these with food to prevent stomach upset.
- Aspirin or NSAIDs — Can irritate stomach lining during fasts.
- Diuretics — May cause dehydration without adequate fluids.
Plan medication dosing appropriately within eating or fasting windows. Break fasts early with food if feeling unwell.
Scheduling Medications Around Meals
To gain the most benefits from intermittent fasting, schedule necessary medication doses to align with planned mealtimes. For example, if eating between noon to 8pm daily:
- Take morning medication with breakfast at noon.
- Take midday or afternoon medication with lunch or dinner.
- Avoid medication after 8pm to prevent late snacking.
Ask a pharmacist or doctor to provide exact guidance tailored to the medications you take.
Making Dietary Changes to Accommodate Medications
Certain dietary considerations also help take medications safely during intermittent fasting windows:
- Drink plentiful fluids like water, unsweetened coffee/tea.
- Combine pills with soft foods like applesauce or yogurt.
- Avoid grapefruit which interacts with many medications.
- Restrict use of alcohol which increases side effects.
Check with your healthcare provider about any specific dietary restrictions.
Who Should Use Caution with Intermittent Fasting
While evidence shows intermittent fasting benefits most healthy adults, some people require a more customized approach or should not fast without medical guidance. Use added caution if:
Taking Medications for Diabetes
People using insulin or oral blood sugar lowering pills risk spikes or crashes in glucose while fasting. Work closely with your endocrinologist to make appropriate medication adjustments to prevent hypoglycemia.
Breastfeeding a Baby
Nursing mothers have higher calorie and nutrient needs. Strict fasting can diminish milk quality and supply. Most lactation experts recommend limiting fasting periods to 14 hours at the most.
Children or Teenagers
Youth need adequate energy and nutrition for proper growth and development. Consult pediatricians before recommending fasting for minors or tweens under age 18.
Underweight or Malnourished
People who are very lean, frail from illness or have nutritional deficiencies should meet full calorie needs instead of prolonged fasting.
While intermittent fasting does show promise for health, safety comes first. Get personalized medical advice about using medications during fasting periods.
Healthy Lifestyle Habits While Intermittent Fasting
Combining intermittent fasting with overall healthy lifestyle habits produces the best and safest results:
Emphasizing Nutrient Dense Foods
Fill non-fasting hours with plenty of vegetables, fruits, whole grains, beans, lentils, nuts, seeds and lean protein. This floods the body with antimicrobial and antioxidant compounds lacking during fasting.
Exercising Regularly
Incorporate both cardio and strength training sessions during fed states. This prevents loss of energy or muscle mass while fasting.
Supporting Gut Health
Eat probiotic and prebiotic foods at meal times to maintain a beneficial intestinal microbiome. Consider taking daily probiotic capsules as well.
Reducing Stress
Find healthy stress relief through yoga, meditation, nature immersion and good sleep hygiene. Lower stress balances hormones disrupted by fasting.
Being under a doctor's care provides safety backup when experimenting with intermittent fasting while taking medications or having an existing health condition. Make it a success by integrating other positive lifestyle factors.
The Bottom Line
Research continues to unveil unique mechanisms that make intermittent fasting one of the most effective health and longevity interventions. The key is following best practices customized to your situation, including proper coordination with prescription medications under medical guidance. This thoughtful approach allows reaping the most rewards from fasting periods while avoiding problems.
FAQs
Can I take supplements while intermittent fasting?
Yes, most dietary supplements like vitamins, minerals, fish oil, probiotics, protein powder or greens powders can be taken during fasting periods as long as you drink enough fluids. Time them alongside meals when possible.
What if I feel sick when taking medication while fasting?
Stop fasting immediately if you experience signs of illness like dizziness, weakness, shakes, nausea or cold sweats after taking medications without food. Eat something small, rest and contact your doctor if symptoms persist.
Will medications work as well if I take them while fasting?
Most oral medication absorption and effectiveness remains unaffected by intermittent fasting. Some studies even show increased potency on an empty stomach. Discuss any notices changes with your pharmacist or physician.
Can I apply topical medications during a fast?
Yes, topical medications in forms like creams, ointments, sprays, eye drops or eardrops can be used as directed during fasting periods without breaking the fast or interfering with the medication's effects.
