Is hair loss a side effect of Xiidra?

No, hair loss isn’t a side effect of Xiidra. This side effect wasn’t reported in the drug’s clinical trials.

Some research shows there may be an association between alopecia (a condition that causes hair loss) and dry eye disease (the condition doctors prescribe Xiidra to treat).

Are there long-term side effects with Xiidra?

No, it’s not likely. Long-term side effects weren’t reported in the drug’s clinical trials.

Most side effects associated with Xiidra happen immediately after your dose and go away within a few minutes or hours.

If you have questions about the long-term side effects of Xiidra, talk with your doctor.

Blurred vision

Blurred vision is a possible side effect you may experience after applying a dose of Xiidra. However, this side effect wasn’t common in the drug’s clinical trials. And blurred vision caused by the drug isn’t expected to last. Your symptoms should go away after a couple of minutes or hours at most after you apply Xiidra eye drops.

Headache

Although rare, you may experience a headache from using Xiidra eye drops. It’s not clear why this side effect happens after using the drug. However, it wasn’t commonly reported in the drug’s clinical trials.

What you can do

If you develop a mild headache after using Xiidra, here are some ways to manage your symptoms at home:

  • apply an ice pack to your head or neck
  • practice meditation, yoga, or similar mindfulness activities
  • avoid alcohol until your symptoms go away, if applicable
  • take an over-the-counter pain reliever such as Tylenol (acetaminophen), if your doctor or pharmacist says the pain reliever is safe for you to use

If you consistently experience headaches that bother you or don’t go away while taking Xiidra, let your doctor know. They can evaluate your symptoms for other possible causes. If your symptoms are likely caused by Xiidra, your doctor may recommend that you stop using the eye drops or switch to a different treatment.

Allergic reaction

As with most drugs, Xiidra can cause an allergic reaction in some people. Allergic reactions weren’t reported in Xiidra’s clinical trials, but they have happened since the drug was approved for use.

Symptoms can be mild or serious and can include:

  • skin rash
  • itching
  • flushing
  • swelling under your skin, typically in your eyelids, lips, hands, or feet
  • swelling of your mouth, tongue, or throat, which can make it hard to breathe

What you can do

For mild symptoms of an allergic reaction, call your doctor right away. They may recommend ways to ease your symptoms and determine whether you should keep taking Xiidra. However, if your symptoms are serious and you think you’re having a medical emergency, immediately call 911 or your local emergency number.

Bad taste

Dysgeusia (metallic taste in the mouth) is a side effect Xiidra eye drops may cause. However, it was rarely reported in the drug’s clinical trials. Reports indicate this side effect typically lasts around 3 or 4 hours after applying a dose of Xiidra, although your experience may differ.

With dysgeusia, you experience a metallic or bad taste in your mouth. It may also cause foods you eat to taste metallic or bitter.

What you can do

Talk with your doctor if you experience dysgeusia while using Xiidra. Dysgeusia may go away with continued use of the eye drops. If this side effect bothers you or doesn’t go away, your doctor will likely stop your Xiidra treatment and recommend other dry eye treatments.

Sinusitis

Sinusitis (inflammation in your sinuses) is an uncomfortable but mild side effect Xiidra may cause. While sinusitis can be severe, no instances of serious sinusitis were reported in the drug’s clinical trials.

Symptoms of sinusitis can vary but may include:

  • green or yellow nasal discharge
  • postnasal drip (mucus that runs down the back of your throat)
  • pain or pressure in your face
  • runny or stuffy nose
  • reduced sense of smell or taste
  • sore throat
  • headache
  • cough

What you can do

If your sinusitis symptoms are mild, you may be able to treat them at home. Some tips include:

  • drinking plenty of fluids to stay hydrated
  • using a humidifier or vaporizer to keep your sinuses moist
  • rinsing your nasal passages using a nasal spray or nasal drops

Talk with your doctor if you notice symptoms of sinusitis that don’t go away or bother you while using Xiidra. They can evaluate whether you need a prescription treatment. They can also determine whether you should continue using Xiidra.

Be sure to talk with your doctor about your health history before you take Xiidra. This drug may not be the right treatment for you if you have certain medical conditions or other factors that affect your health. These are considered drug-condition or drug-factor interactions. The conditions and factors to consider include:

Contact lenses. If you wear contact lenses, it’s typically safe to use Xiidra. However, it’s important that you remove your contacts before each dose. You should wait at least 15 minutes after your Xiidra dose before replacing your contacts.

Allergic reaction. If you’ve had an allergic reaction to Xiidra or any of its ingredients, your doctor will likely not prescribe Xiidra. Ask your doctor about other medications that may be better options for you.

Alcohol with Xiidra

There’s no known interaction between using Xiidra and consuming alcohol.

However, some research has shown that drinking alcohol may be a risk factor for developing dry eye disease. This is the condition Xiidra is used to treat. It’s possible that drinking alcohol could worsen your dry eye symptoms. This may make it seem that Xiidra isn’t working.

If you drink alcohol, talk with your doctor to learn more about how it could affect dry eye and whether minimizing or avoiding it would be best for your dry eye symptoms.

Pregnancy and breastfeeding while taking Xiidra

It’s not known if it’s safe to take Xiidra while pregnant or breastfeeding. The drug’s clinical trials didn’t include pregnant people.

That said, Xiidra is an eye drop. Most of the medication stays in your eye, and the rest of your body doesn’t absorb much after you use it. So it’s unlikely that Xiidra would cause harm if used during pregnancy or while breastfeeding.

If you’re pregnant, breastfeeding, or planning for either, talk with your doctor. They can help determine whether Xiidra is safe for you.

Side effects of Xiidra are typically mild and go away after a few minutes or hours. Most side effects the drug can cause affect your eyes and only happen right after you administer a dose. The only serious side effect associated with the drug to date is allergic reaction.

If you’d like to learn more about Xiidra, talk with your doctor or pharmacist. They can help answer any questions you have about the drug’s side effects.
