Malaria · Drug comparison
Both can prevent malaria where recommended, but the right choice depends on the destination and your health. Doxycycline is often less expensive per tablet and continues for 28 days after leaving the risk area; sun sensitivity and stomach or esophageal irritation matter. Atovaquone-proguanil continues for 7 days afterward and is generally well tolerated, but severe kidney impairment can rule it out. Compare full-course cost and your medication interactions with the clinician.

|---|---|---|
| Cost (generic) | Compare a full-course quote | Compare a full-course quote |
| Start before entering the malaria area | 1 to 2 days before | 1 to 2 days before |
| Continue after leaving the malaria area | 4 weeks (longer commitment) | 7 days (short tail) |
| Dosing | Once daily | Once daily, with food |
| Main downsides | Sun sensitivity, stomach upset, take upright with water | Cost; avoid in severe kidney disease |
| Cannot use if | Pregnant, on isotretinoin, allergic to tetracyclines | Severe kidney impairment, pregnant |

Stopping early can leave you unprotected. Doxycycline continues for a full 28 days after leaving the malaria area; atovaquone-proguanil continues for 7 days. Discuss which schedule you can complete, but convenience alone does not determine whether a drug is safe for you.
Mefloquine is another prevention option with weekly dosing and important neuropsychiatric and cardiac cautions. It is outside Bidwell’s service scope. A travel-medicine clinician can assess whether it or another option is appropriate; this is a service boundary, not a universal ban on remote prescribing.
Bidwell Health can review your trip and prescribe doxycycline or Malarone online when it is clinically appropriate, sent to your pharmacy.
A $45 asynchronous visit (no video, no membership) for adults in eligible states. Tell us your destination and dates and we match the pill to your trip. Request it at least two weeks ahead when you can, since you start before you leave.
Neither is best for everyone. The clinician checks destination guidance, health, interactions and cost. Doxycycline has a 28-day after-exposure course and can cause sun sensitivity or esophageal irritation; atovaquone-proguanil has a 7-day course afterward and is not used for prevention with severe kidney impairment.
Doxycycline must be continued for 4 weeks after leaving the malaria area. Malarone is continued for only 7 days after. That shorter tail is one of Malarone's main advantages for short trips.
Doxycycline is often cheaper per tablet, but it requires a longer after-travel course. Compare the full prescribed quantity of each drug, including shipping, before choosing. Drug choice also depends on destination, safety and interactions, not price alone.
No. Combining doxycycline with isotretinoin can raise pressure around the brain (pseudotumor cerebri). If you take isotretinoin, you should not use doxycycline for malaria; a clinician must assess an alternative such as atovaquone-proguanil, including its own contraindications.
For an illustrative 7-day stay in a malaria area, starting 2 days before entry means 37 daily doses of doxycycline (2 + 7 + 28), or 16 daily doses of atovaquone-proguanil (2 + 7 + 7). These are planning examples, not prescriptions; your clinician confirms the medicine, dose and dates. CDC malaria prevention guidance.
