Doxycycline is an antibiotic drug in the class of antibiotics called tetracyclines. It’s the name of the active ingredient. The medicine is available in various brands with different names, appearances, and packaging. Whichever brand you’re prescribed, Doxycycline fights the infection in the very same way.
Doxycycline’s dosage forms include capsules, tablets, suspension, and injections. The most popular strengths of tablets and capsules are 50mg, 75mg, and 100mg.
What Are the Doxycycline Uses?
Doxycycline is used in the treatment of various health conditions:
- Acne
- Rosacea
- Respiratory tract infections
- Gum disease
- Eye infections
- Malaria infections
A doctor may also prescribe this medication for other reasons, such as:
- Preventing malaria, especially for people travelling in high-risk areas
- Avoiding risk of sexually transmitted illnesses in bisexual, gay, and other men who engage in sex with other men.
- Treating infections caused by ticks, mites, or lice
Please ask your doctor if you’re unsure why you’re taking Doxycycline.
How Does Doxycycline Work?
Doxycycline stops bacterial growth. For example, it works in acne by reducing bacteria on the skin’s surface. This drug is also believed to have an anti-inflammatory action.
How to Take Doxycycline
You should take Doxycycline exactly as directed by your healthcare provider. Follow the guide on your prescription label. Do not use this medication in smaller or larger quantities or longer than recommended.
Take capsules or tablets with a full glass of water. We recommend drinking plenty of liquids while taking this medicine. Most brands can be taken with milk or food if needed. However, different doxycycline brands may have different instructions about taking them with or without food.
Swallow a delayed-release tablet or capsule whole; please do not break, crush, or open it. Try to sit up or stand for at least 30 minutes after taking Doxycycline. That reduces your risk of developing oesophagus irritation (oesophagitis).
Do not stop taking this medicine until your healthcare provider tells you that it’s OK to do so.
Forgotten, Missed Dose, and Overdose
In case you miss your dose, do this:
- If it’s close to the usual time, take it as soon as you remember. Then, take subsequent doses at the usual times.
- If it’s close to when you take the next dose, take your next dose at the time you planned and continue as usual. You don’t want to take a double dose to compensate for the missed dose.
Please call your pharmacist or doctor if you need clarification. Seek emergency medical help or contact the Poison Help line if you overdose on Doxycycline.
