Forget to Take Your Malaria Tablets? Here’s What to Do

Published

Antimalarial tablets are effective in preventing malaria, a disease caused by mosquitoes. 

They contain medications that kill the malaria parasites in your body, protecting you from transmission. It’s vital to take these tablets as prescribed to ensure continuous protection.

But what happens when you forget a dose? This article will dive into each consideration.

Immediate Actions After Forgetting a Dose

If you forget to take a malaria tablet, don’t panic. 

It’s always important to keep your prescribing physician informed if you miss a dose or experience any issues. This can be tough while traveling, but with Runway Health, every online consultation includes access to chat-based care before, during, and after your travels, so you can message your physician directly for personalized guidance and reassurance whenever questions arise.

If you can’t get in touch with your physician, first check how much time has passed since your scheduled dose. If it’s just a few hours, no worries – take your next dose right away. If it’s too close to your next dose (for example, tomorrow), then skip today and continue tomorrow. 

Avoid multi-dosing, as it can lead to side effects and won’t provide extra protection.

Avoiding Double Dosing: Clear Guidelines

Taking two tablets at once does not make up for a missed dose and can actually create new problems.

Malaria medications like Malarone (Atovaquone/Proguanil) and Doxycycline are carefully formulated so that each tablet provides a specific, steady level of protection in your bloodstream. Doubling up can spike the drug concentration far above what your body is meant to handle at one time, which does not increase your level of protection but does increase the likelihood of side effects.

Potential issues include nausea, vomiting, dizziness, headaches, or severe stomach upset, and in rare cases, more serious complications such as liver stress or abnormal heart rhythms. For Doxycycline, taking extra tablets can heighten the risk of esophageal irritation or ulceration, especially if the dose is not taken with adequate water. For Malarone, double dosing can lead to intensified gastrointestinal symptoms or a sudden rise in liver enzymes.

Instead of trying to “catch up,” it is safest to resume your normal schedule as soon as possible and continue taking your next dose at the regular time.

Contacting a Healthcare Professional During Travel

If you’re unsure about what to do, reach out to your healthcare provider. They can guide you on the best course of action. 

They may recommend adjusting your schedule or offer additional advice based on your specific situation.

If you use Runway Health at get a prescription for Malarone, you get unlimited chat-based care with your physician – which allows you to connect to a doctor online, anywhere in the world.

Many travelers prefer this peace-of-mind, knowing they have a health expert to guide them during uncertainties or issues like missed doses.

Strategies to Compensate for Missed Doses

To catch up on missed tablets, take the next one at the usual time. It’s essential not to take extra tablets to make up for the ones you missed. 

If you’ve missed multiple doses, consult your healthcare provider. They might adjust your dosage to ensure continued protection.

Catching Up Safely: Supplementing Missed Tablets

Supplementing missed tablets involves returning to your regular schedule and not taking extra tablets. If you missed several doses, your healthcare provider may suggest a different approach to maintain effectiveness.

Adjusting Subsequent Doses

To ensure continuous protection, follow your healthcare provider’s recommendations for adjusting subsequent doses. They may provide specific instructions based on the number of missed tablets and the type of medication you’re taking.

Monitoring for Potential Symptoms

Even with missed doses, it’s vital to monitor for potential malaria symptoms. These include fever, chills, headache, and muscle aches. If you experience any symptoms, seek medical attention promptly, regardless of missed doses.

  • Recognizing Early Signs of Malaria – Early signs of malaria are similar to flu-like symptoms. Pay attention to any changes in your health and seek medical help if you suspect malaria, even if you’ve missed doses.
  • When to Seek Help – If you experience symptoms or have concerns about missed doses, contact your healthcare provider immediately. Early detection and treatment are crucial to prevent complications associated with advanced stages of malaria.

Communicating with Healthcare Providers

Be transparent with your healthcare provider about missed doses. 

Share accurate information about the number of tablets you missed and any symptoms you’re experiencing. Their guidance is essential for addressing the situation effectively.

Seeking Professional Advice on Adjustments

Consult your healthcare provider for advice on adjusting your treatment plan. They may recommend changes based on the number of missed doses and your overall health.

Preventive Measures Going Forward

To avoid future oversights, establish a routine for taking your malaria tablets. 

Integrate reminders, such as phone alarms or pill organizers, to help you stay on track. Consistency is key to effective malaria prevention.

Establishing a Routine

Incorporate taking your malaria tablets into your daily travel routine. This could be during meals or before bedtime, making it a habit that reduces the likelihood of forgetting.

Create Reminder Systems

Use technology to your advantage. Set alarms on your phone to receive notifications when it’s time to take your tablets. These reminders serve as a helpful tool to stay consistent with your medication schedule.

You might also consider using a medication adherence tool, or an app that helps you tracks doses. These devices provide an extra layer of accountability, helping to reduce missed doses and ensuring that protective levels of the medication remain in your system throughout your trip. Consistent adherence is critical for malaria prevention, and the right tool can make it easier to maintain a reliable routine even when traveling across time zones or keeping a busy itinerary.

Commonly Asked:

What if I miss more than one tablet?

If you miss multiple tablets, consult your healthcare provider. They can provide guidance on adjusting your dosage to maintain effectiveness.

Are there specific symptoms of malaria I should watch for?

Yes, symptoms include fever, chills, headache, and muscle aches. Seek immediate medical attention if you experience these, even if you’re taking malaria tablets.

Can I adjust my tablet schedule to make up for missed doses?

Follow your healthcare provider’s recommendations for adjusting subsequent doses. 

They may provide specific instructions based on the number of missed tablets and the type of medication you’re taking.

Can I combine my malaria tablets with other medications?

Again, consult your healthcare provider before combining preventive malaria pills with other medications. 

Some drugs may interact, affecting their efficacy or causing adverse effects. Your healthcare provider can provide personalized advice based on your medical history.

Are there specific foods or drinks I should avoid when taking malaria tablets?

For most malaria medications there are no strict dietary bans, but certain foods and drinks can affect how well the tablets work or how comfortable you feel while taking them. Malarone (Atovaquone/Proguanil) is generally very flexible and can be taken with or without food, though doctors recommend taking it with a meal or a milky drink to improve absorption and reduce stomach upset.

Doxycycline requires more care. It should be taken with a full glass of water and not on an empty stomach, because it can irritate the esophagus and cause heartburn. Travelers are advised to avoid dairy products, calcium-fortified juices, or antacids within about two hours of a dose because calcium, magnesium, and aluminum can reduce absorption and lower effectiveness. Iron supplements can have a similar effect.

Because each traveler’s itinerary and health profile can differ, it’s always best to discuss your diet and supplement use with a healthcare provider.

It’s crucial not to ignore side effects, as they may impact the overall effectiveness of the malaria tablets.

Final Thoughts on Forgetting to Take Malaria Tablets

Remember – missing a malaria tablet doesn’t mean all is lost. Follow the guidance provided by your healthcare provider, take the next dose as scheduled, and be vigilant for any symptoms. 

Establishing a routine and using reminders can help prevent future oversights. Remember, consistent adherence to your malaria prevention plan is paramount for your health and well-being.
