Product Description

Doxycycline Capsules IP 100 mg is a broad-spectrum antibiotic from the tetracycline class, combined with lactic acid bacillus (a probiotic) to support gut health. 

It is used to treat various bacterial infections, including urinary tract infections (UTIs), intestinal infections (e.g., traveler's diarrhea), respiratory tract infections (e.g., pneumonia, bronchitis), eye infections (e.g., trachoma), gum infections (periodontitis), and sexually transmitted infections (STIs) like gonorrhea and syphilis. 

Bacterial infections occur due to the overgrowth of harmful bacteria inside or on the body. Doxycycline does not treat viral infections (e.g., colds, flu) or fungal/parasitic conditions. The probiotic component helps restore beneficial gut flora disrupted by antibiotics, reducing the risk of diarrhea.

Avoid being allergic to tetracyclines. Not recommended for children under 8 years (risk of tooth discoloration/permanent enamel hypoplasia) or during pregnancy/breastfeeding without medical advice.

Uses

Doxycycline 100 mg Capsules (with lactic acid bacillus) are indicated for:

• Bacterial infections of the urinary tract (UTIs), respiratory tract (e.g., acne, chlamydia), gastrointestinal tract (e.g., cholera, Helicobacter pylori), skin/soft tissue, eyes (e.g., conjunctivitis), gums (periodontitis), and genitals (e.g., gonorrhea, syphilis)

• Adjunct in malaria prevention or treatment of rickettsial infections (e.g., Rocky Mountain spotted fever)

• Acne vulgaris (moderate to severe) or rosacea (as an anti-inflammatory)

Use only for confirmed or suspected bacterial infections; complete the full course to prevent resistance. Typical duration: 7–14 days, depending on the infection.

How it works

Doxycycline 100 mg Capsules contain doxycycline hyclate, which inhibits bacterial protein synthesis by reversibly binding to the 30S ribosomal subunit, preventing the growth and spread of susceptible bacteria (bacteriostatic effect, but can be bactericidal at high doses).

It is effective against a wide range of Gram-positive, Gram-negative, and atypical bacteria. The included lactic acid bacillus (a probiotic) is a beneficial microorganism that colonizes the gut, helping to restore the balance of good bacteria disrupted by infections or antibiotic use, thereby preventing or alleviating antibiotic-associated diarrhea.

Benefits

Doxycycline 100 mg Capsules effectively combat bacterial infections like UTIs, respiratory issues, eye/gum infections, and STIs (e.g., gonorrhea, syphilis), providing relief from symptoms such as pain, fever, discharge, or swelling within 48–72 hours.

The probiotic addition minimizes gastrointestinal side effects like diarrhea, improving tolerability. It is particularly useful for conditions requiring broad-spectrum coverage, such as acne or malaria prophylaxis, and supports faster recovery when used as prescribed, reducing complication risks.

How to use

Take one 100 mg capsule every 12 hours (or as directed, e.g., 200 mg on day 1 followed by 100 mg daily) for the full prescribed duration.

• Swallow the capsule whole with a full glass of water while sitting or standing upright to prevent esophageal irritation; do not chew, crush, or open it.

• Take with food or milk to reduce stomach upset, but avoid dairy, antacids, iron supplements, or multivitamins within 2–3 hours, as they impair absorption.

• For best results, take at evenly spaced intervals; if a dose is missed, take it as soon as remembered unless near the next dose—do not double up.

• In children ≥8 years or elderly/renal-impaired patients, dose adjustments may be needed; consult a doctor. Do not self-medicate.

Side Effects

• Nausea

• Vomiting

• Stomach upset or abdominal pain

• Loss of appetite

• Diarrhea (less likely due to probiotic, but possible)

Safety Advice

• Alcohol: Avoid or limit alcohol, as it may exacerbate GI side effects or reduce efficacy; no direct interaction, but consult your doctor if concerned.

• Pregnancy: Category D (contraindicated, especially 2nd/3rd trimester—risk of fetal bone/teeth abnormalities and reduced uterine contractions). Use only if benefits outweigh risks (e.g., life-threatening infections); effective contraception advised.

• Breastfeeding: Avoid, as it passes into breast milk and may cause rash, diarrhea, or photosensitivity in infants. Pump and discard milk during treatment, plus 5 days after.

• Driving/Operating Machinery: May cause dizziness or blurred vision; use caution until effects are known.

Storage Conditions

• Store at a temperature below 30°C (86°F), in a cool, dry place away from direct sunlight, heat, and excessive moisture.

FAQs

What is the use of Doxycycline 100mg?

Doxycycline capsules are used to  treat infections by preventing the growth and spread of bacteria

Can I stop Doxycycline Capsules from being used on my own?

It is recommended to complete the course of Doxycycline Capsules IP 100mg even if you feel better, as it is an antibiotic. Leaving it in between may lead to even severe infection that will, in fact, stop responding to the antibiotic as well (antibiotic resistance).

Does Doxycycline dosage cause diarrhoea?

Doxycycline capsule 100mg is unlikely to cause diarrhoea as it contains lactic acid bacillus, a friendly bacterium. Lactic acid bacillus is a probiotic that helps restore the balance of good bacteria in the gut, which may have been upset due to infections or the use of antibiotics. Therefore, it helps in preventing diarrhoea.

Does the Doxycycline dose cause photosensitivity?

Doxycycline, which might make you sunburn more easily. Wear protective clothing, sunglasses, and sunscreen whilst going outside.
