Drug doxycycline is indeed a drug that can be done as prevention of malaria for people who want to travel to malaria endemic areas. Usually these drugs are taken 1x a day regularly over a period of time to work well to prevent malaria.
As with other drugs, doxycycline has side effects. Not everyone is affected by this effect, but the usual side effects reported are:
Nausea
Gag
Diarrhea
Missing appetite
Itching on the anus or vagina
Dizzy
Swallowing pain
Tongue swelling
Dry mouth
Anxious, pounding, excitement
Back pain
Skin color change
If you feel side effects such as headache, blurred vision, red spots on the skin, bleeding, shortness of breath, chest pain, joint pain or other irresistible symptoms, consult your doctor immediately.
In addition, it would be better if you drink it at the same time each day.
Choose a time where you can always drink it because if it is not regular, the levels in the blood will also not be stable. If you miss a dose, drink it immediately but if it is past a day, skip it and continue drinking it as usual. The most important thing is do not take two doses in 1 day.
So, hopefully useful.
