Vanliga frågor

How long does it take for tetracycline to work?

For most infections tetracycline starts to work after the first dose, with most people noticing improvements in their symptoms after 2-3 days. For acne it can take 6-8 weeks and for rosacea it may take several weeks to see noticeable results.

Is it safe to take tetracycline during pregnancy?

No, it is not safe to take tetracycline during pregnancy, especially after the first trimester. Tetracycline can affect the development of bones and teeth in a baby.

Can I drink alcohol while taking tetracycline?

You can drink alcohol in moderation while taking tetracycline. Alcohol does not stop tetracycline from working, however it may increase side effects such as stomach upset, dizziness, or feeling unwell. For best results, you should limit alcohol until you finish your course and feel fully recovered.

Why does tetracycline stain teeth?

Tetracycline can stain teeth because it sticks to calcium in developing teeth. Over time, this causes the teeth to change colour, starting yellow, then turning brown or grey as they’re exposed to light. Once this happens, the staining is permanent.

Why can't you take tetracycline before bed?

You should not take tetracycline before bed because lying down straight after taking it increases the chance of it getting stuck, causing irritation and possible inflammation of the throat. You should take it with a full glass of water and stay upright for at least 30 minutes afterwards.
