Doxycycline is an antibiotic that is used to treat a variety of infections caused by bacteria, including urinary tract infections, pneumonia, skin infections, and sexually transmitted infections like gonorrhea and syphilis.
It works by inhibiting the growth of bacteria, preventing their ability to multiply and spread.
Doxycycline belongs to a class of drugs known as tetracyclines. It is also commonly used in the treatment of acne, rosacea, and other types of bacterial infections.
Doxycycline is available as a tablet, capsule, or liquid suspension. It is usually taken once a day, and is available in the form of a liquid or liquid capsule.
Doxycycline is usually taken with or without food, but it can be taken on an empty stomach. It is important to take this medicine regularly to get the most benefit from it.
It can also be taken with or without food, but it is important to take the medication at the same time each day. You can take it with or without food, but you should continue to take it as prescribed.

Malaria is a serious tropical disease spread by mosquitoes. If it isn’t diagnosed and treated promptly, it can be fatal.
A single mosquito bite is all it takes for someone to become infected.
Symptoms of malaria
It’s important to be aware of the symptoms of malaria if you’re travelling to areas where there’s a high risk of the disease. Symptoms include:
a high temperature (fever) sweats and chills headaches vomiting muscle pains diarrhoea Symptoms usually appear between 7 and 18 days after becoming infected, but in some cases the symptoms may not appear for up to a year, or occasionally even longer.
When to seek medical attention
Seek medical help immediately if you develop symptoms of malaria during or after a visit to an area where the disease is found.
Malaria risk areas
Malaria is found in more than 100 countries, mainly in tropical regions of the world, including:
large areas of Africa and Asia Central and South America Haiti and the Dominican Republic parts of the Middle East some Pacific islands
Thehas more information about the risk of malaria in specific countries.
Preventing malaria
Many cases of malaria can be avoided. An easy way to remember is the ABCD approach to prevention:
Awareness of risk – find out whether you’re at risk of getting malaria before travelling Bite prevention – avoid mosquito bites by using insect repellent, covering your arms and legs, and using an insecticide-treated mosquito net Check whether you need to take malaria prevention tablets – if you do, make sure you take the right antimalarial tablets at the right dose, and finish the course Diagnosis – seek immediate medical advice if you develop malaria symptoms, as long as up to a year after you return from travelling
Side effects
Like all medicines, doxycycline can cause side effects, although not everyone gets them.
Common side effects These common side effects happen in around 1 in 10 people. Keep taking the medicine, but talk to your doctor or pharmacist if these side effects bother you or don’t go away:
a headache feeling sick or vomiting being sensitive to sunlight Serious side effects Serious side effects are rare and happen in less than 1 in 1,000 people.
Call a doctor straight away if you get:
Bruising or bleeding you can’t explain (including nosebleeds), a sore throat, a high temperature (38C or above) and you feel tired or generally unwell – these can be signs of blood problems.
Severe diarrhoea (perhaps with stomach cramps) that contains blood or mucus, or lasts longer than 4 days ringing or buzzing in your ears
Serious skin reactions or rashes, including irregular, round red patches, peeling, blisters, skin ulcers, or swelling of the skin that looks like burns – these could be signs of a rare reaction to the medicine called Stevens-Johnson Syndrome
Yellow skin or the whites of your eyes go yellow – this could be a sign of liver problems joint or muscle pain that has started since you began taking doxycycline
Headache, vomiting and problems with your vision – these could be signs of pressure around your brain (intracranial hypertension)
A fingernail coming away from its base – this could be a reaction to sunlight called photo-onycholysis
A sore or swollen mouth, lips or tongue
Severe pain in your tummy, with or without bloody diarrhoea, feeling sick and being sick – these can be signs of pancreatitis difficulty or pain when you swallow, a sore throat, acid reflux, a smaller appetite or chest pain which gets worse when you eat – these could be signs of an inflamed food pipe (oesophagitis) or oesophageal ulcer
Serious allergic reactions
Allergic reactions to doxycycline are common and occur in more than 1 in 100 people.
These are not all the side effects of doxycycline.
You can report any suspected side effect to the UK.
When and how often to take doxycycline
The for doxycycline can vary depending on the area surveyed.
Clinical Pharmacology:Doxycycline hyclate (200 mg/d) for the treatment of rosacea. Doxycycline hyclate is indicated for the treatment of rosacea. Doxycycline hyclate can reduce the number of red or pimples, tinea pedis, and tinea corporis and provides relief from the symptoms of rosacea. Doxycycline hyclate may be used alone or in combination with other topical therapies.
Efficacy:Clinical studies have shown a significant improvement in the ability of rosacea patients to achieve and maintain a regular, hard, clean, moist, and comfortable appearance (acne, facial flushing, increased blood flow, and sensitivity to sunlight). There have been many clinical trials on rosacea, and results have been reported in over 50% of rosacea patients. However, there have been very few clinical trials comparing rosacea with other measures of severity or treatment of rosacea.
Mechanism of Action:Doxycycline is a tetracycline dihydrate and is an inhibitor of the biosynthesis of the proteins important for cell division. Doxycycline was shown to be an effective agent in studies comparing the efficacy of doxycycline hyclate and doxycycline for the treatment of rosacea. The mechanism of action of doxycycline is due to its ability to penetrate the oral mucosa and inhibit the growth of bacteria. Doxycycline is a broad spectrum antimicrobial agent with antifungal and antibacterial activity against a variety of gram-positive and gram-negative organisms.
Use in Children:There have been no controlled clinical trials on the use of doxycycline hyclate in children.
Use in Pediatric Patients:Doxycycline is not recommended for use in pediatric patients below the age of 8 years. Doxycycline is not recommended for use in patients with severe hepatic, renal or cardiac disease. Because of the risk of gastrointestinal adverse events associated with doxycycline, intravenous infusion of doxycycline or a combination of doxycycline and aspirin is considered the recommended treatment for this indication in pediatric patients.
Doxycycline and Salicylic AcidDoxycycline is a tetracycline that inhibits protein synthesis. Salicylic acid is an anhydride. Doxycycline is a broad spectrum antimicrobial agent that is bactericidal and non-selective for bacteria.
Doxycycline is not recommended for use in pediatric patients under the age of 8 years. Doxycycline is not recommended for use in pediatric patients with severe hepatic, renal or cardiac disease.
Clinical studies have demonstrated that doxycycline is a potent inhibitor of the synthesis of the proteins important for cell division.
Clinical studies have demonstrated that doxycycline is a potent inhibitor of the biosynthesis of the proteins important for cell division.
Use in Pediatric Patients with Other Indications:
Doxycycline is used for the treatment of various bacterial infections like that of chest, lung or nose (Ex. bronchitis, pneumonia, sinusitis), urinary tract (Ex. cystitis, urethritis), skin (Ex. acne), eyes or sexually transmitted diseases (Ex. gonorrhoea, syphilis, chlamydia).
It is also used to treat fevers associated with louse or tick bites and malaria (when chloroquine is ineffective). It can also be used to prevent certain infections like scrub typhus (a disease carried by small insects), Rocky Mountain spotted fever, travellers’ diarrhoea, malaria and leptospirosis.
Doxycycline:Tetracycline antibiotics
Doxycycline works by inhibiting the growth and replication of bacteria. It does this by binding to the bacterial ribosome, preventing the synthesis of proteins that are essential for the bacteria's survival.
Consult your doctor if you experience:
Do NOT take Doxycycline at the same time as:- take for 7 days if you have had an allergic reaction to doxycycline, any other tetracycline antibiotics or or nitroimidazines.-take for 5 days before becoming pregnant, orthodoxy, steer clear from others or unsuitable foodstake with food (lactagLYE and FUJER)
