Active Ingredients: Doxycycline
Respiratory tract and urinary tract infections caused by Klebsiella species Some Gram-positive bacteria have developed resistance to doxycycline. Indeed, malaria has become an increasing problem due to drug resistance.
As divers venture deeper into the tropics they incur increasing risk of contracting malaria. Lack of medical facilities, transportation and communication add additional complexity to managing this medical emergency.
Understanding malaria prophylaxis and general preventative measures is therefore of the utmost importance. The following section covers the most important considerations in selecting and using malaria prophylactic measures and medications.
This will stop the medicine irritating your food pipe or stomach. What if I forget to take it?
If you forget to take a dose, take it as soon as you remember, unless it's nearly time for your next dose. In this case, just leave out the missed dose and take your next dose as normal. Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.
You could also ask your pharmacist for advice on other ways to remember your medicines. What if I take too much? Accidentally taking an extra dose of doxycycline is unlikely to harm you.
Non-limiting examples of aryl groups include phenyl, toluyl, naphthyl, pyrrolyl, pyridyl, imidazolyl, thiophenyl, and furyl.
An aryloxy group can be, for example, an oxygen atom substituted with any aryl group, such as phenoxy. An aralkyl group can be, for example, any alkyl group substituted with any aryl group, such as benzyl.
An arylalkoxy group can be, for example, an oxygen atom substituted with any aralkyl group, such as benzyloxy. A heterocycle can be any ring containing a ring atom that is not carbon, for example, O, P, Si, or any other heteroatom.
A heterocycle can be substituted with any number of substituents, for example, alkyl groups and halogen atoms. A heterocycle can be aromatic heteroaryl or non-aromatic.
Non-limiting examples of heterocycles include pyrrole, pyrrolidine, pyridine, piperidine, succinamide, maleimide, morpholine, imidazole, thiophene, furan, tetrahydrofuran, pyran, and tetrahydropyran. An acyl group can be, for example, a carbonyl group substituted with hydrocarbyl, alkyl, hydrocarbyloxy, alkoxy, aryl, aryloxy, aralkyl, arylalkoxy, or a heterocycle.
Non-limiting examples of acyl include acetyl, benzoyl, benzyloxycarbonyl, phenoxycarbonyl, methoxycarbonyl, and ethoxycarbonyl. An acyloxy group can be an oxygen atom substituted with an acyl group.
An ester or an ester group comprises an acyloxy group. A non-limiting example of an acyloxy group, or an ester group, is acetate.
A carbamate group can be an oxygen atom substituted with a carbamoyl group, wherein the nitrogen atom of the carbamoyl group is unsubstituted, monosubstituted, or disubstituted with one or more of hydrocarbyl, alkyl, aryl, heterocyclyl, or aralkyl.
When the nitrogen atom is disubstituted, the two substituents together with the nitrogen atom can form a heterocycle.
