Haloperidol Oral Side Effects

Dizziness, drowsiness, difficulty urinating, sleep disturbances, headache, and anxiety may occur. If these effects persist or worsen, notify your doctor or pharmacist promptly.

Tell your doctor promptly if any of these side effects occur: muscle spasm/stiffness, shaking (tremor), restlessness, mask-like facial expression, drooling. Your doctor may prescribe another medication for you to take with haloperidol to decrease these side effects.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

In rare cases, haloperidol may increase your level of a certain chemical made by the body (prolactin). For females, this increase in prolactin may result in unwanted breast milk, missed/stopped periods, or difficulty becoming pregnant. For males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor immediately.

For males, in the unlikely event you have a painful or prolonged erection (lasting more than 4 hours), stop using this drug and seek immediate medical attention, or permanent problems may occur.

This medication may rarely cause a condition known as tardive dyskinesia. In some cases, this condition may be permanent. Tell your doctor immediately if you develop any facial/muscle twitching such as tongue thrusting, chewing movements, puffing or puckering of your mouth, or uncontrollable shaking.

This medication may rarely cause a serious condition called neuroleptic malignant syndrome (NMS). Seek immediate medical attention if you develop any of the following symptoms: fever, muscle stiffness, severe confusion, increased sweating, fast/irregular heartbeat.

Tell your doctor immediately if any of these rare but very serious side effects occur:
