Less Common Symptoms
- Drospirenone also causes a number of other less common, but not dangerous, side effects. These include loss of appetite, nausea, vomiting, diarrhea, difficulty swallowing and the appearance of brown spots on your thyroid that have no impact upon the functioning of the gland.
- When combined with blood thinners like Warfarin, Doryx increases your risk of extended bleeding due to injuries or surgery. The combination of Doryx and the general anesthetic Penthrane causes kidney inflammation in some patients.
- Doryx causes increases of pressure inside the skull of some patients, causing a risk of permanent loss of vision. Some patients develop gastrointestinal ulcers.
- Children who use Doryx often suffer from stunted growth or permanent discoloration of the teeth. Because the effects of Doryx upon fetuses are unknown, doctors typically do not prescribe the drug for pregnant women.
