Tetracyclines
What are they? Tetracyclines are a widely used group of antibiotics in the treatment of bacterial infections.
What are they good for? Although the development of strains of bacteria resistant to tetracyclines has reduced their effectiveness in some conditions, they are still used for chest infections caused by chlamydia and mycoplamsa micro-organisms. They are also used in the treatment of non-specific urinary infections, cholera, brucellosis and rarer conditions, such as Q fever. Long-term treatment with these drugs can improve acne when taken orally or applied to the skin as a solution
How do they work? Antibiotics, of which tetracyclines are one group, work either by killing the bacteria directly or by halting its ability to multiply, allowing the body's natural defences to overcome the remaining infection.
Any contraindications? They are not recommended for those with poor kidney function as they can cause further deterioration in the condition. Tetracyclines can increase the action of oral anticoagulants and reduce the effectiveness of oral contraceptives. Antacids and milk may interfere with the absorption of tetracyclines.
Possible side-effects? Common side-effects include nausea, vomiting and diarrhoea. Rashes may develop and if prescribed for children or pregnant mothers, it can cause discolouration of developing teeth. - Dr Muiris Houston
Alternative Remedy: Honey
What is it? Honey is the nectar of the flowers of plants, gathered by bees, stored in their stomachs for transport to the hive and there concentrated by evaporation.
What is it good for? Taken internally, honey is effective in the treatment of colds, flus and respiratory infections such as bronchitis, rhinitis and sinusitis. It is also used externally in the treatment of burns, surgical wound infections and surgical incisions.
How does it work? Natural bee honey contains the extracts of many medicinal flowering plants. The plant nectars are altered through the digestive system of the bees to form new compounds. Honey contains many valuable enzymes, antibiotic agents, minerals, proteins and vitamins.
Any contraindications? Honey is not recommended for infants under 12 months, as their digestive systems are not fully formed. Wildflower honey, as opposed to clover or alfalfa honey (which are usually heavily sprayed with pesticides), contains the broadest range of valuable compounds.
Possible side-effects? In rare instances, people with allergic reactions to bee stings may have adverse reactions to honey. - Sylvia Thompson
