Doxycycline is available in various strengths, including:

• Oral capsules (50 mg, 75 mg, 100 mg, 150 mg)
  
• Oral tablets (20 mg, 50 mg, 75 mg, 100 mg, 150 mg)
  
• Oral suspension (25 mg/5 mL, 50 mg/5 mL)
  
  

The typical starting dose of doxycycline for bacterial infections can vary depending on factors such as the type of infection, its severity, your age, and other medical conditions. It's crucial to follow your healthcare provider's instructions regarding dosage and administration carefully.

For most adults and children 8 years and older with bacterial infections, the typical starting dose of doxycycline may be:

• 100 mg taken orally twice daily for capsules or tablets
  
• 200 mg taken orally once daily for capsules or tablets, depending on the condition being treated
  

For pediatric patients younger than 8 years old, the dose may be adjusted based on weight and the specific infection being treated. The oral suspension is often used for pediatric dosing.

Doxycycline should be taken with a full glass of water to avoid irritation of the esophagus and to ensure proper absorption. It's generally recommended to take it on an empty stomach, at least 1 hour before or 2 hours after meals unless otherwise instructed by your healthcare provider.

Your healthcare provider will determine the duration of treatment based on the type of infection and your response to the medication. It's important to complete the full course of treatment as prescribed, even if your symptoms improve before the medication is finished.

If you have any questions about your dosage or how to take doxycycline, contact your healthcare provider or pharmacist. If you want to talk to a provider right away, consider booking an online doctor appointment on Sesame to discuss your concerns.

If you miss a dose of doxycycline, take it as soon as you remember. If it's close to the time for your next dose, skip the missed dose and continue with your regular dosing schedule. Avoid taking a double dose of doxycycline to make up for a missed one.

Continue taking doxycycline as prescribed by your healthcare provider, even if you start feeling better. Abruptly stopping doxycycline can lead to rebound symptoms or complications. Follow your provider's instructions regarding the duration of treatment.

Store doxycycline according to the instructions provided by your healthcare provider or pharmacist. It should be kept at room temperature, away from excessive heat, light, and moisture. Ensure the container is tightly closed and keep the medication out of the reach of children.
