Is it okay to wear a pad when i insert monistat for a yeast infection to prevent it from getting on my underwear?

Yes: Yes, you can use a pad. Probably best to not use a tampon, to allow the cream to distribute through the vagina.

Of course: No problem at all, in fact sounds quite reasonable! you might want to follow with taking some acidophilus, both my mouth but can also insert a capsule vaginally at bedtime for a few days...

Sure: Doesnt sound like a problem.

Yes: It is fine to wear a pad to protect your underwear. Just remember to change the pad if it gets very wet.
