How to Use This Medicine
Cream, Insert, Suppository
- Your doctor will tell you how much of this medicine to use and how often. Do not use more medicine or use it more often than your doctor tells you to.
- This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
- Wash your hands with soap and water before and after you use this medicine or insert the vaginal ring.
- To use the vaginal cream:
- This cream medicine comes in a tube with a plastic applicator. You will need to use the applicator each time you use the medicine. Wash the applicator with warm, soapy water after each use. Do not use the medicine without the applicator.
- Measure the cream using the marks on the plastic applicator. Make sure you use the correct mark for your specific dose.
- To use the vaginal ring:
- This medicine is contained in a ring that you or your caregiver will put into your vagina. The ring will slowly release small amounts of medicine for your body to absorb. Your caregiver will show you how to insert the ring.
- Leave the ring in its sealed wrapper until you are ready to use it.
- Once the ring is in place in your vagina, you should not be able to feel it. If you feel uncomfortable, the ring may not be inserted far enough. Gently push the ring farther into your vagina. If you feel pain, talk to your doctor.
- You will leave the ring in for 90 days (3 months), unless your doctor tells you a different schedule. After that time, remove the ring and insert a new one. If you forget to remove the ring after 90 days, call your doctor for instructions.
- The ring may move down into the lower part of your vagina accidently. This can happen if you strain to have a bowel movement. Use your finger to gently push the ring back into place. If the ring comes all the way out of your vagina, rinse it off with warm water and put it back in. Call your doctor if the ring comes out several times.
- If you need to remove the ring, hook your finger through the ring and pull it out.
- To use the vaginal tablet:
- The tablet should be used only in your vagina. Do not swallow the tablet.
- Each vaginal tablet comes packaged inside an applicator. Do not take the tablet out of the applicator. If the tablet comes out of the applicator when you open it but has not fallen out of the package, carefully put it back into the applicator for insertion. If the tablet falls out of the applicator when you try to insert it, throw it away and use a new applicator that still has the tablet inside it.
- Take the applicator out of the plastic wrap before you use it.
- Keep your hands clean and dry while you handle the tablet.
- Use the applicator only 1 time and then throw it away. Use a new applicator for each dose.
- It is best to always use this medicine at the same time of day. Most women will start by inserting a new tablet every day for 2 weeks, then change to inserting a new tablet only 2 days each week. Carefully follow the schedule that your caregiver tells you to.
