Description
Generic Doxycycline Antibiotic

Chemical Name: DOXYCYCLINE (dox-i-SYE-kleen)
Doxycycline Hyclate Generic
Vibramycin Hyclate (doxycycline hyclate) is a prescription antibiotic used to treat several types of bacterial infections. It can treat certain lung infections, some sexually transmitted infections, Rocky Mountain spotted fever, other tick-borne illnesses, and more. It may also be used with other treatments for severe acne or to help prevent malaria during short-term travel. It may also be used for people with allergies to penicillins. Doxycycline belongs to a group of antibiotics called tetracyclines, and it works by stopping bacteria from making proteins they need to grow and spread. It does not work for viruses, so it will not treat colds, flu, or other viral illnesses.
You can get this medicine easily from Canada Pharmacy.
Directions
Take Vibramycin Hyclate exactly as prescribed by your healthcare provider. For most adult infections, the usual dose is 200 mg on the first day (taken as 100 mg every 12 hours), followed by 100 mg once per day. More serious infections may need 100 mg every 12 hours.
Childre's doses are based on body weight, and the length of treatment depends on the infection. For malaria prevention, adults usually take 100 mg once per day, starting 1 to 2 days before travel and continued throughout the trip, as well as for 4 weeks after leaving the area (up to 4 months total). Swallow each capsule with a full glass of fluid, and do not take it right before lying down or going to bed. You may take it with food or milk if it upsets your stomach.
Finish all the medicine, even if you feel better. If you miss a dose, take it when you remember, unless it is almost time for your next dose. Do not take two doses at once.
Ingredients
The active ingredient in Vibramycin is doxycycline hyclate. The inactive ingredients in the capsules may include magnesium stearate, microcrystalline cellulose, and sodium lauryl sulfate.
Cautions
Before using this medication, you may want to consult a healthcare provider about the following:
- Any existing health conditions
- Any allergies
- A list of all medications currently being taken
Tetracyclines, including doxycycline, can permanently stain developing teeth with a yellow-gray-brown color and affect bone growth. Therefore, doxycycline is generally not used during the last half of pregnancy, in infants, or in children up to 8 years of age unless the benefits clearly outweigh the risks.
Doxycycline can make the skin much more sensitive to sunlight, leading to a more severe sunburn. Avoid excessive sun and tanning beds, use sun protection, and stop the medication and contact your healthcare provider if your skin becomes red or sunburned.
Take each dose with plenty of fluid, and do not take it just before lying down, to reduce the risk of irritation or ulcers in the esophagus.
Antibiotics, including doxycycline, can cause a serious intestinal infection called Clostridioides difficile-associated diarrhea that may appear during or even weeks after treatment.
In rare cases, tetracyclines have caused increased pressure around the brain, also called intracranial hypertension, with symptoms such as headache, blurred or double vision, or vision loss. Avoid taking doxycycline together with isotretinoin, an acne medication, and seek medical care for vision changes.
Serious skin reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and DRESS, have been reported. Stop the medication and seek medical care if you develop a spreading rash, blistering or peeling skin, or sores in the mouth.
Several products reduce how well doxycycline is absorbed, including antacids that contain aluminum, calcium, or magnesium, iron supplements, and bismuth subsalicylate; separate these from your dose. Doxycycline can also increase the effect of blood thinners, such as warfarin, may make birth control pills less effective, and may be less effective when taken with medicines such as barbiturates, carbamazepine, phenytoin, and rifampin.
As with other antibiotics, doxycycline can lead to the overgrowth of organisms that are not affected by it, such as yeast, which may cause a vaginal yeast infection. Tell your healthcare provider if new symptoms develop.
Tell your healthcare provider if you are pregnant, may become pregnant, or are breastfeeding. Store below 30°C (86°F) in a tightly closed, light-resistant container, and keep it out of reach of children.
Contraindications
Avoid taking or using this medication if any of the following apply:
- A known allergy or hypersensitivity to doxycycline or any other tetracycline-class antibiotic.
Side Effects
Common side effects of Vibramycin Hyclate include:
- Nausea and vomiting
- Diarrhea
- Loss of appetite
- Increased sensitivity to sunlight
- Skin rash
- Irritation or soreness when swallowing
- Vaginal yeast infection
Stop taking Vibramycin Hyclate and get medical help if you have signs of a serious allergic reaction, such as swelling of the face, lips, tongue, or throat, trouble breathing, hives, or a severe, blistering, or peeling skin rash. Contact your healthcare provider for watery or bloody diarrhea, severe or ongoing headache with blurred or double vision, which may be a sign of increased pressure around the brain, pain or trouble when swallowing, yellowing of the skin or eyes, easy bruising or bleeding, or any side effect that is severe or does not go away.
