Can you go swimming while taking clindamycin?

Antibiotics shouldn't affect your ability to swim.

However, the medical condition for which you've been prescribed antibiotics might require you to limit some activities.

You will have been prescribed antibiotics by a medical practitioner. Ring the practitioner or their office and ask whether you need to avoid or be careful about some activities.

Be clear about the kind of activities you are contemplating. For example, are you intending to swim competitively, or in training, or just to take a dip in a pool or the ocean, to splash around?
