Yes, it is quite common to experience sleepiness, headaches, and a feeling of weakness while taking Deviry 10 (medroxyprogesterone). These symptoms are typical hormonal side effects as your body adjusts to the medication. Please try to get plenty of rest, stay well-hydrated, and consider taking your dose close to bedtime to help manage the drowsiness. These effects usually subside as your body adapts, but if they become severe or worry you, please reach out to your doctor for guidance.
