Doxycycline generally offers a good safety profile for acne treatment, but prolonged use can present some risks. Extended courses may increase your susceptibility to yeast infections, particularly Candida. Monitor for symptoms like vaginal itching or thrush. Also, long-term use can disrupt gut bacteria, potentially leading to digestive upset. A balanced diet rich in probiotics may help mitigate this.
Sun Sensitivity
Doxycycline significantly increases your skin’s sensitivity to sunlight. This photosensitivity makes you much more prone to sunburn, even with minimal sun exposure. Use a broad-spectrum sunscreen with an SPF of 30 or higher daily, even on cloudy days. Seek shade during peak sun hours (10 am to 4 pm), and wear protective clothing like hats and long sleeves when outdoors. Reapply sunscreen frequently, especially after swimming or sweating.
Other Potential Long-Term Effects
While rare, long-term doxycycline use has been associated with tooth discoloration in children and discoloration of the nails. For children, discuss potential long-term side effects thoroughly with your doctor. If you notice any unusual changes in your teeth or nails, consult your doctor immediately.
