First, let me tell you what doxycycline is and what it is used for. Doxycycline is a tetracycline antibiotic that inhibits bacterial growth and is thought to have anti-inflammatory effects. Doxycycline is used to treat many different bacterial infections including acne, urinary and respiratory tract infections, eye infections, gum disease, gonorrhea, chlamydia, and syphilis. It can also be used prevent malaria and treat infections caused by mites, ticks, or lice.
Some common questions that people have about doxycycline are:
- How should I take doxycycline?
- What are the possible side effects of doxycycline?
- What are the interactions of doxycycline with other drugs or foods?
- What are some alternatives to doxycycline?
- What are the reviews of doxycycline from other users?
How should I take doxycycline?
The usual dose of doxycycline is 100mg to 200mg, taken once or twice a day. You might take a lower dose, such as 40mg once a day or 20mg twice a day, for rosacea or gum infections. Children younger than 12 years old may need to take a lower dose than adults. The dose depends on your child’s age and weight.
You should take doxycycline exactly as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.
Doxycycline comes in different forms, such as tablets, capsules, liquid, and injection. Depending on the form you are taking, you may need to follow different instructions on how to take it. Here are some general tips:
- If you are taking tablets or capsules, swallow them whole with a full glass of water while sitting or standing. Do not break, crush, chew, or open them.
- If you are taking liquid doxycycline, shake it well before each use. Measure the dose with a marked measuring spoon, oral syringe, or medicine cup. Drink plenty of fluids to avoid throat irritation and ulceration.
- If you are taking delayed-release tablets or capsules, you may take them with or without food. However, if they upset your stomach, you may take them with food or milk. You may also sprinkle the contents of the capsules on a spoonful of cold, soft applesauce and swallow it right away without chewing.
- If you are taking doxycycline to prevent malaria while traveling, start taking the medicine 1 or 2 days before you travel. Take the medicine every day during your trip and continue taking it for 4 weeks after you return. However, do not use the medicine for longer than 4 months.
- If you are using Oracea™ delayed-release capsules for rosacea, you should take this medicine on an empty stomach, preferably at least 1 hour before or 2 hours after meals.

What are the interactions of doxycycline with other drugs or foods?
Doxycycline may interact with other drugs or foods and affect how they work or increase the risk of side effects. Therefore, you should tell your doctor about all the medicines you are taking, including prescription and nonprescription drugs, vitamins, and herbal products.
Some examples of drugs that may interact with doxycycline are:
- Antacids, calcium supplements, iron products, and laxatives containing magnesium. These products may reduce the absorption of doxycycline and make it less effective. You should take doxycycline at least 2 hours before or 4 hours after taking these products.
- Birth control pills. Doxycycline may make birth control pills less effective. You should use another method of contraception while taking doxycycline and for at least 7 days after finishing it.
- Blood thinners, such as warfarin. Doxycycline may increase the effect of blood thinners and cause bleeding problems. You may need to have your blood tested more often and adjust your dose of blood thinners while taking doxycycline.
- Penicillin antibiotics, such as amoxicillin and ampicillin. Doxycycline may reduce the effectiveness of penicillin antibiotics and make them less able to treat infections. You should not take doxycycline and penicillin antibiotics at the same time.
- Retinoids, such as isotretinoin and acitretin. These drugs are used to treat severe acne and other skin conditions. They may increase the risk of intracranial hypertension (increased pressure in the brain) when taken with doxycycline. You should not take doxycycline and retinoids at the same time.
Some examples of foods that may interact with doxycycline are:
- Dairy products, such as milk, cheese, yogurt, and ice cream. These foods may also reduce the absorption of doxycycline and make it less effective. You should avoid eating or drinking dairy products within 2 hours before or after taking doxycycline.
- Alcohol. Drinking alcohol while taking doxycycline may increase the risk of liver damage and stomach irritation. You should limit your alcohol intake while taking doxycycline.
- Grapefruit juice. Grapefruit juice may increase the amount of doxycycline in your blood and cause more side effects. You should avoid drinking grapefruit juice while taking doxycycline.
These are not all the possible interactions of doxycycline with other drugs or foods. You should always check with your doctor or pharmacist before taking any new medicines or changing your diet while taking doxycycline.
What are some alternatives to doxycycline?
Doxycycline is not suitable for everyone. Some people may be allergic to it or have other medical conditions that prevent them from taking it safely. Some people may also prefer to use other treatments for their infections.
If you are looking for some alternatives to doxycycline, you may want to consider the following options:
- Other tetracycline antibiotics, such as minocycline, tetracycline, or demeclocycline. These drugs have similar effects and uses as doxycycline but may have different side effects and interactions. They may also be more expensive than doxycycline.
- Other types of antibiotics, such as macrolides (e.g., azithromycin), fluoroquinolones (e.g., ciprofloxacin), sulfonamides (e.g., sulfamethoxazole), or cephalosporins (e.g., ceftriaxone). These drugs may be effective against different types of bacteria than doxycycline and may be used for different infections. However, they may also have different side effects and interactions than doxycycline. They may also be less effective against some bacteria that are resistant to them.
- Non-antibiotic treatments, such as topical creams, gels, or lotions for acne or rosacea; antihistamines, corticosteroids, or anti-inflammatory drugs for allergic reactions or inflammation; antimalarial drugs, such as chloroquine or mefloquine, for malaria prevention or treatment; or antiparasitic drugs, such as ivermectin or permethrin, for infections caused by mites, ticks, or lice. These treatments may have different mechanisms of action and benefits than doxycycline but may also have different side effects and interactions than doxycycline. They may also be less effective than doxycycline for some conditions.
These are not all the possible alternatives to doxycycline. You should always consult your doctor before switching to another treatment for your infection. Your doctor will be able to recommend the best option for you based on your medical history, condition, and preferences.
What are the reviews of doxycycline from other users?
Doxycycline is a widely used antibiotic that has helped many people treat their infections. However, like any medicine, it may not work for everyone or cause some unwanted effects. The reviews of doxycycline from other users may vary depending on their individual experiences and expectations.
To get an idea of what other users think of doxycycline, you can read some of their reviews online. For example, you can visit [Drugs.com], [WebMD], or [Everyday Health] and search for doxycycline. You will find ratings and comments from users who have taken doxycycline for different conditions.
Here are some examples of reviews from these websites:
- “I was prescribed Doxycycline 100mg twice a day for 10 days to treat a sinus infection. I started feeling better after 3 days but then I developed severe nausea, vomiting, diarrhea, and loss of appetite. I had to stop taking it after 7 days because I couldn’t tolerate it anymore. It also made my skin very sensitive to sunlight and I got sunburned easily. I don’t recommend this drug at all.”
- “I have been taking Doxycycline 40mg once a day for rosacea for about 6 months now and it has been amazing. My skin is clear and smooth and I have no side effects at all. It also helps with my acne and prevents breakouts. It is a bit expensive but worth it for me. I highly recommend this drug for rosacea.”
- “I took Doxycycline 100mg once a day for 2 weeks to prevent malaria while traveling in Africa. It worked well and I didn’t get sick at all. However, it made me very dizzy and tired and gave me headaches and stomach cramps. It also stained my teeth yellow and made them sensitive. I’m glad I didn’t have to take it longer than 2 weeks.”
These are just some examples of reviews from other users. You should keep in mind that these reviews are subjective and may not reflect the average or typical experience of taking doxycycline. You should also remember that everyone reacts differently to medicines and that your experience may be different from others.
