What should I watch for?

Tell your doctor or health care professional if your symptoms do not start to get better in a few days. If you are taking this medicine for a long time, visit your doctor or health care professional for regular checks. If you notice any changes in your vision see your eye doctor for an eye exam.

If you get a fever during or after you start taking this medicine, do not treat yourself. Contact your doctor or health care professional immediately.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells.

While in areas where malaria is common, you should take steps to prevent being bit by mosquitos. This includes staying in air-conditioned or well-screened rooms to reduce human-mosquito contact, sleep under mosquito netting, preferably one with pyrethrum-containing insecticide, wear long-sleeved shirts or blouses and long trousers to protect arms and legs, apply mosquito repellents containing DEET to uncovered areas of skin, and use a pyrethrum-containing flying insect spray to kill mosquitos.

This medicine can make you more sensitive to the sun. Keep out of the sun. If you cannot avoid being in the sun, wear protective clothing and use sunscreen. Do not use sun lamps or tanning beds/booths.

Avoid products with antacids and kaolin for 4 hours before and after taking a dose of this medicine.
