Does Doxycycline cause nausea when taken on an empty stomach? 

Yes, Doxycycline does cause nausea when it is taken on an empty stomach. Doxycycline is an antibiotic and such meds are always heavy on the stomach and cause symptoms like nausea, vomiting, diarrhoea, abdominal pain, etc. 

It’s not surprising for Doxycycline to act in the same way. Another reason for antibiotic-induced gastrointestinal side effects is the mechanism through which these meds work. 

Doxycycline and other antibiotics kill bacterial growth non-selectively and not all bacteria present in our body are infectious. Some gut bacteria are considered ‘good’ and they are essential for normal digestion. When antibiotics damage the good bacteria, your GI side effects increase significantly. 

What does research suggest?

There have been several studies and reports investigating the potential link between doxycycline and nausea. One research study indicated that Doxycycline can cause nausea and vomiting 3-times more frequently than other antibiotics (1).

Another study indicated that taking Doxycycline after a meal reduced the incidence and severity of nausea compared to taking it on an empty stomach. This indicates that taking Doxycycline with food can reduce the intensity of nausea.

However, it may still cause nausea to some extent. If you are taking Doxycycline and are concerned about any of the side effects, reach out to your doctor. 

What to do if Doxycycline causes Nausea when taken on an empty stomach? 

If taking Doxycycline with an empty stomach makes you nauseous, take your antibiotic with food. This way the med will not come in direct contact with the lining of your stomach and the acid will be utilized to help digest the food. 

However, I would recommend not taking antibiotics with dairy products or acidic foods. The rest seems fine. Another proper way to prevent GI side effects on Doxycycline is the concomitant use of probiotics. 

Probiotics replenish the good bacteria killed by your antibiotics and help get some relief from GI side effects. Although it is a basic practice to prescribe probiotics with antibiotics, it might not be a practice in every country of the world.

If your doctor hasn’t prescribed you, you can ask your local pharmacist for a probiotic and you don’t really need a prescription to purchase them. If you’re concerned about any other side effects, talk to your doctor or pharmacist.
