Doxycycline 100mg Capsules - Vibramycin Antibiotic, Box of 30

Doxycycline treats a broad range of bacterial infections, including chest and respiratory infections, urinary tract infections, skin and soft tissue infections, and gum infections. It is commonly prescribed for chlamydia and other sexually transmitted infections, for acne and rosacea. It is also used to prevent malaria in travellers, but it does not work against viral infections.

Take one 100 mg capsule with a full glass of water while sitting or standing, and stay upright for at least 30 minutes. For most infections the first day uses 100 mg every 12 hours, followed by 100 mg once a day. Take it at the same time each day, keep dairy, antacids and iron two hours away, and finish the whole course.

Common side effects are nausea, vomiting, diarrhea, headache and rash. Doxycycline can make your skin more sensitive to sunlight, so use sun protection. It can also irritate the food pipe if a capsule is swallowed without enough water or while lying down. Rare but serious effects include severe allergic reactions, raised pressure inside the head, and diarrhea caused by C. difficile.

There is no direct chemical interaction between alcohol and doxycycline, so the occasional drink is unlikely to cause a problem. Heavy drinking, however, can slow healing, may reduce how well the antibiotic works, and can worsen nausea or stomach upset. If you have a history of alcohol dependence or liver problems, speak to your doctor before starting a course.

Yes. Antacids, dairy products, and calcium or iron supplements block absorption and should be kept at least two hours from a dose. Doxycycline is not recommended with isotretinoin, because the combination raises the risk of raised pressure inside the head. It can also strengthen the effect of blood thinners such as warfarin, and it is generally avoided during pregnancy and breastfeeding.

Many people notice an improvement within one to two days, but symptoms can take longer to settle and the full course must be completed to clear the infection. If your symptoms get worse or do not improve within a few days, contact a doctor instead of repeating the course.
