Managing energy and fatigue around infusions

Managing energy with myasthenia gravis (MG) often starts with understanding how treatment days affect your body and planning around these factors whenever possible. And if you receive infusion therapy for MG, you probably know that managing fatigue around infusions can be just as challenging as treatment itself.

Infusion days may leave you more tired than usual, and the recovery period can disrupt your regular routine. Learning why this happens and how to prepare can help you conserve your energy and feel more in control of your MG treatment schedule.

Why infusion days can be physically draining

MG infusion fatigue happens for several reasons. The treatment itself takes time, sometimes several hours, during which you’re sitting still in an infusion center. Meanwhile, your body is working hard to process the medication, on top of the muscle weakness and tiredness that MG already brings.

Getting to and from your appointment can be exhausting. You’ll arrange a ride, check in, sit in the waiting room, receive your infusion, and then make the trip back home. Every step uses energy you may already be running low on.

Your body is also reacting to the infusion medication. Depending on the treatment, you may experience temporary side effects like headaches or fever, or you may just feel generally unwell.

Stress or anxiety about the appointment can wear you out before you even arrive. Worrying about side effects, timing, or how you’ll feel afterward adds a mental load that often shows up as physical fatigue.

Preparing your energy before infusion day

Planning for infusion days starts well before you walk into the clinic. Try to do less in the days leading up to treatment. If possible, clear your schedule the day before so you can rest and build up extra energy.

Get as much good sleep as you can the night before your infusion. Fatigue before and after infusions can pile up quickly, so starting out rested makes a difference. If MG symptoms are making sleep hard, let your care team know and ask for recommendations.

The night before, pack a small infusion bag. Include your insurance cards, a medication list, water bottle, snacks, phone charger, and anything else that might make the visit more comfortable. You’ll grab it when it’s time to leave without wasting energy in the morning.

It’s also important to eat a balanced meal before you leave home because low blood sugar (from skipping a meal) can reduce your energy levels and worsen fatigue. Aim for foods that give you steady energy rather than a quick spike and crash.

Even if you are able to drive yourself, asking someone to give you a ride can take a load off your body and mind.

Conserving energy during the infusion

Energy conservation during infusions means finding ways to rest while you receive treatment. Here are some energy-saving tips for MG patients:

• Bring items that help you relax, whether that’s a book, headphones, a tablet, a favorite blanket, or something else.
• Close your eyes and rest during the infusion.
• Stay hydrated, if it’s safe for you, by sipping water during and after your appointment.
• Let your care team know if you feel uncomfortable at any point.
• Ask for help adjusting your position, getting a pillow or blanket, or changing the room temperature.
• If your infusion center has recliners or beds instead of regular chairs, choose those when you can.

Managing fatigue after the infusion

Post-infusion weakness and fatigue often peak in the hours immediately following treatment. If you can, plan to go straight home and rest instead of trying to run errands or jump back into work.

Give yourself at least 24 hours of lighter activity after an infusion. MG infusion day fatigue doesn’t always fade overnight. Some people need a full day or two to feel more like themselves.

As you recover, watch for patterns in how treatment makes you feel. Certain infusions may leave you more tired than others, or you may notice other side effects that affect the days following. Tell your care team if you notice any patterns. They may be able to adjust your premedication protocol or infusion schedule to help combat fatigue.

If you need to nap, take one. If you only have energy for light tasks, stick with those. Pushing through severe fatigue may prolong recovery or worsen your symptoms. Listening to your body with MG and honoring your limits is an important part of protecting your strength over time.

Stay in contact with your care team about coping with infusion-related fatigue. If your exhaustion is worsening or not improving, it may be a sign that your treatment needs adjustment or that something else is contributing to your fatigue.

Practical tips for caregivers

Caregiver support on infusion days can make a world of difference. If you’re helping someone with MG, your role goes far beyond just providing a ride. There are plenty of tasks that can help ease their stress.

Once the infusion is over, you can help with physical tasks that take energy. Making a meal, throwing in a load of laundry, keeping track of medications, or handling household chores gives your loved one a chance to rest without worrying about to-dos piling up.

You might also find it useful to jot down a few notes after each infusion. That could include any side effects, how long it takes before they start to feel better, and what seems to make their fatigue better or worse. This record can be helpful to the care team when they are thinking about adjusting medications or planning future treatments.

Fatigue management for a chronic illness like MG is an ongoing process. What works well for one infusion cycle might need adjusting for the next. Pay close attention to how your body feels and tell your care team if you have any questions or concerns about treatment day or the fatigue that follows.
