Your doctor will determine the appropriate doxycycline dosage based on your individual health and the specific procedure. Typically, a single dose of 100mg is prescribed the day before your HSG. This prophylactic dose helps reduce the risk of infection.
Doxycycline Before HSG
Take the prescribed dose with a full glass of water, preferably at least one hour before your HSG or as instructed by your physician. Avoid taking it with dairy products, antacids, or iron supplements as these can hinder absorption.
Doxycycline After HSG
Following the procedure, your doctor may prescribe a course of doxycycline to prevent post-HSG infection. This commonly involves taking 100mg twice a day for several days, typically between one and five days post-procedure. Always follow the prescribed dosage and duration meticulously. Do not stop taking the medication prematurely, even if you feel better.

Potential Side Effects
While generally well-tolerated, doxycycline can cause side effects like nausea, vomiting, diarrhea, or photosensitivity. Report any unusual symptoms to your doctor immediately. Proper hydration during treatment is recommended.
